Five Ways to Save Heat That You Might Not Have Considered

Friday, February 3rd, 2012

Finding new ways to lower the heating bills for your New Britain home is always a challenge. Maybe you’ve already insulated and sealed every crawlspace and crack, or you might have recently upgraded that old furnace, but there are always other ways to reduce heat loss in the winter.

Here are five ways to conserve heat that you might not have considered.

1. Insulate Recessed Light Fixtures

While recessed light fixtures save space and give you more control over lighting and design, such as task lighting in kitchens, they can be a hidden source of heat loss. Feel around your recessed lighting fixtures to see if there’s cool air or a draft. If you do, they could need more insulation. However, you have to be extremely cautious about what type of insulation you use around electrical wiring and fixtures. Check with the manufacturer, or call an electrician if you aren’t sure what type of insulation to use.

2. Insulate Water Heater Tanks

Part of your heating bill each month goes to heating the water in your home. Whether you have a gas, electric, solar, or hybrid hot water heater, every water heater tank has an R-value that determines how much heat it loses. If you have a low R-value, your tank may need more insulation. Call a professional plumber or check your owner’s manual for the R-value of the model you own, but the general rule is that if the tank is warm when you touch it, you may need to buy a “jacket” for your water heater. These are fairly inexpensive, easy to install, and can be found relatively anywhere you buy insulation.

3. Open Curtains on South End

The southern end of your home will get the most sunlight in the winter. If you have curtains or blinds on your windows or doors, leave them open during the day, and make sure you close them at night. Opening them will help warm up the home naturally during the day, and closing them will help keep the cold air out and warm air in at night.

4. Storm Windows and Doors

Many homeowners know they have the option of upgrading old doors and windows that leak air, but not everyone can afford to upgrade all the doors and windows at once. You can also install storm windows and doors to help reserve heat. Before you start comparing prices, remember to measure, since measurements will affect the cost.

5. Close Fireplace Flue

Whenever your flue is open, you are losing large amounts of heat. Close the damper if the fireplace or chimney is not being used. You can also consider upgrading to a more air tight damper.

You can always call Carney Plumbing, Heating & Cooling whenever you have questions about lowering your heating costs for your New Britain home.

Basic Home Heating Safety Tips

Wednesday, February 1st, 2012

While you should schedule a yearly maintenance visit with a qualified HVAC technician to check for any safety concerns, you can also reduce potential safety hazards in the heating system of your North Wales home. Whether you have a furnace, heat pump, or boiler, you can substantially decrease the chances of dangerous situations with a few minor routine tasks.

If you have any questions about how to better maintain your heating system, give Carney Plumbing, Heating & Cooling a call to speak with one of our expert HVAC technicians. Here are a few guidelines to get you started.

Ventilation in Forced-air Systems:

Regularly vacuum and clean out your heating vents and fan blower.
Check the condition of your chimney and vent pipe to make sure that none of the parts are damaged or show signs of deterioration.
Test the thermostat occasionally to make sure your heating system is working at optimal levels. There could be a safety concern if your heater is not properly heating your home.

Heat Exchangers:

Heat exchangers should be inspected often to prevent carbon monoxide leaks. Check for any obvious issues, such as rust or other damages.
The heat exchanger for furnaces should be inspected by a professional once a year in case there are hidden problems with the equipment, or if any of the components need to be replaced.
Check the pilot light in gas furnaces for any flickers or changes in color. Have someone turn up the thermostat while you watch the light, but turn off the system for five minutes first. If there are any changes, there could be a problem with the heat exchanger. Call a professional if you suspect issues with your heat exchanger.

Heating Equipment Inspections and Adjustments:

Boilers should be drained regularly to reduce sediment buildup, in addition to testing the water level safety controls. It’s best to have a North Wales professional perform these tasks if you aren’t sure how to do them on your own.
Adjust the temperature settings if you suspect that the heater isn’t working properly, and if it doesn’t work call a professional heating technician, or if you aren’t sure how to locate or adjust the controls.
Check the overall equipment for cracks, rust, or any other obvious signs of damage or deterioration that could create safety hazards.

In addition to performing these tasks, call a licensed heating contractor to inspect your heating system at least once a year.

Heating Installation Guide: System Ventilation 101

Monday, January 30th, 2012

What’s critical for proper ventilation during heating system installation?

Combustion heating systems (oil or gas) require adequate combustion air, typically supplied via unintentional air leaks or dedicated ducts to the outdoors.
A correctly functioning chimney (natural draft or manufactured) is essential to safely carry away combustion byproducts like carbon monoxide, preserving indoor air quality.
When installing a new 80%+ AFUE furnace, reline the chimney, older liners can be damaged by acidic condensation from higher-efficiency appliances.
Upgrading to a 90%+ AFUE unit or heat pump may eliminate the need for the old chimney; consider separately venting the water heater or resizing the chimney liner accordingly.
For fan-assisted furnaces installed between 1987-1993, inspect for horizontal venting in high‑temperature plastic, these recalled configurations should be replaced with stainless steel vent pipe, sometimes with an added draft-inducing fan.
Floor furnaces with long vent runs near the floor can pose safety risks; any signs of gas odors indicate an urgent venting issue requiring immediate professional attention.

Maintaining Proper Ventilation for Combustion Systems

Anytime you maintain, retrofit, or replace a gas heating system in your Buckingham home you also need to be concerned with air quality. Combustion air is needed by all oil and gas heating systems to support the combustion process. This air is provided in some homes by unintentional air leaks, or by air ducts that connect to the outdoors. The combustion process creates several byproducts that are potentially hazardous to human health and can cause deterioration in your home. You can protect yourself from these hazards, as well as maintain energy efficiency, by ensuring that your chimney system functions properly and that your gas heating system is properly ventilated. In some cases, installing a sealed-combustion furnace can also help.

Chimneys

Properly functioning chimney systems will carry combustion byproducts out of the home. Therefore, chimney problems put you at risk of having these byproducts, such as carbon monoxide, spill into your home.

Most older gas furnaces have naturally drafting chimneys. The combustion gases exit the home through the chimney using only their buoyancy combined with the chimney’s height. Naturally drafting chimneys often have problems exhausting the combustion gases because of chimney blockage, wind or pressures inside the home that overcome the buoyancy of the gases. Homeowners should also be aware of the signs of an undersized furnace, as improper system size can worsen ventilation and efficiency problems.

Atmospheric, open-combustion furnaces, as well as fan-assisted furnaces, should be vented into masonry chimneys, metal double-wall chimneys, or another type of manufactured chimney. Masonry chimneys should have a fireclay, masonry liner or a retrofitted metal flue liner.

Many older chimneys have deteriorated liners or no liners at all and must be relined during furnace replacement. A chimney should be relined when any of the following changes are made to the combustion heating system:

When you replace an older furnace with a newer one that has an AFUE of 80% or more. These mid-efficiency appliances have a greater risk of depositing acidic condensation droplets in chimneys, and the chimneys must be prepared to handle this corrosive threat. The comparison of high versus mid-efficiency furnaces can help you understand which system type will best fit your home while ensuring your chimney is properly lined. The new chimney liner should be sized to accommodate both the new heating appliance and the combustion water heater by the installer.

When you replace an older furnace with a new 90+ AFUE appliance or a heat pump. In this case, the heating appliance will no longer vent into the old chimney, and the combustion water heater will now vent through an oversized chimney. This oversized chimney can lead to condensation and inadequate draft. To avoid these issues, it’s crucial to check if your HVAC system is properly sized before installation and make sure venting is handled by a qualified professional.

Other Ventilation Concerns

Some fan-assisted, non-condensing furnaces, installed between 1987 and 1993, may be vented horizontally through high-temperature plastic vent pipe (not PVC pipe, which is safely used in condensing furnaces). This type of venting has been recalled and should be replaced by stainless steel vent pipe. If horizontal venting was used, an additional draft-inducing fan may be needed near the vent outlet to create adequate draft. Floor furnaces may have special venting problems because their vent connector exits the furnace close to the floor and may travel 10 to 30 feet before reaching a chimney. Check to see if this type of venting or the floor furnace itself needs replacement. If you smell gases, you have a venting problem that could affect your health. Contact your local utility or Buckingham heating contractor to have this venting problem repaired immediately.

Chimneys can be expensive to repair, and may help justify installing new heating equipment that won’t use the existing chimney.

HVAC Installation Guide: Where to Place a Thermostat for Accurate Heating

Monday, January 23rd, 2012

It’s easy to forget that with your furnace in the basement churning away all day to keep your Lansdale home warm, but your thermostat is the single most important device in ensuring your home is heated to the temperature you want. If it stops working or it misreads the temperature inside your home, your furnace won’t know what temperature it actually is and will turn on and off at the wrong time.

Where Not to Place Your Thermostat

To avoid inaccurate readings, avoid placing your thermostat in the following locations:

Direct Sunlight – Direct sunlight will almost always increase the perceived temperature of the thermostat. Unless you live in a greenhouse, this will be very uncomfortable for everyone in your home.
Windows – Windows can result in direct sunlight and breezes. If the windows are not properly sealed, cold air can blow in and make it seem cooler in your home than it really is. In any of these cases, your thermostat will misread the indoor temperature.
Drafts – Drafts from improperly sealed doors, windows, or anything else in your home can negatively impact the thermostat.
Heat Vents – Don’t place your thermostat near a radiator or heat vent where it is likely to be warmer than anywhere else in the house.
Kitchens – Kitchens tend to be warmer than other rooms in the house, especially when in use. Avoid placing a thermostat here unless you have a zone control system and your kitchen is separate from other rooms.

A properly placed thermostat will ensure your home is heated or cooled to the temperature you desire regardless of outdoor conditions. If you’re unsure whether your thermostat is calibrated properly, check the temperature with a separate thermometer in a different location in the same room. If it is significantly warmer or cooler in one place than another, try to determine which is more indicative of the actual comfort level in your Lansdale home. When properly located, your thermostat should never be an issue again.

What Is the Best Temperature to Heat My Home?

Friday, January 20th, 2012

Saving on energy costs is important for every Gwynedd Valley homeowner, but it’s not always clear what the average temperature would need to be in order to lower your heating bills. Generally, it’s best not to turn your thermostat above 68°F when you are at home, and to turn it down ten to fifteen degrees when you leave the house or while you’re sleeping. This can save up to 15% on your heating bills, but keep in mind that this percentage is greater in milder climates than colder climates.

Remembering to turn down the heat when you don’t need it is the biggest challenge when trying to save heat. One of the easiest ways to do this is to install a programmable thermostat that allows you to set the times you want the heat turned up or down. This will ensure that you are consistent with turning your heat down, and you can set it to turn on before you get up in the morning so that the house is already warm when you get out of bed. Depending on the brand and setting options, programmable thermostats are relatively inexpensive and easy to install.

One common misunderstanding about thermostats is that it takes more energy for the heating system to warm up the house after the thermostat has been turned down for an extended period of time. The belief is that the energy saved by not producing heat is cancelled out by the work it takes to heat up the home again. This is not the case, however, since the lower the temperature is inside your home, the longer it takes to lose heat. You will actually save more energy the longer the thermostat is set at a lower temperature. Conversely, the same theory applies to the cost of cooling your home in the summer, since higher interior temperatures slow down the flow of heat into the home.

Overall, if you want to save on heating costs, you should keep your home below 70°F as much as possible, and turn down the thermostat about fifteen degrees when you don’t need the heat. Closing off the doors and vents to unused rooms will also save energy, and you can put on extra clothing to help remind you to turn down the heat a few degrees while you are home. You don’t have to spend a fortune to heat your Gwynedd Valley home if you are consistent with your thermostat settings.

Comparing High-Efficiency and Mid-Efficiency Furnaces

Wednesday, January 18th, 2012

Whenever you are in the market for a new furnace for your Perkasie home, there are many models to choose from. Many of the furnaces manufactured within the last few years are high-efficiency furnaces with a high AFUE rating (AFUE measures the amount of fuel the furnace converts into heat). When people refer to a mid-efficiency furnace, they are usually talking about older furnaces.

Single-stage furnaces were considered to be an efficient heating system when they were manufactured, but compared to newer furnaces, they use up a lot more energy than they need to. Single-speed furnaces are designed to run at full capacity until the temperature inside the home reaches the thermostat setting. After they shut off, the home not only loses heat, but the furnace will also take longer and burn more fuel when it cycles on again.

Newer, two-speed and multispeed models run consistently at lower speeds, and the ones with variable-speed blowers are even more efficient because they can operate at various levels. These models will also automatically adjust to the thermostat to maintain a constant temperature, which saves energy by keeping the home at a consistent temperature so that there’s little heat loss.

When shopping for a new furnace, keep in mind that the AFUE ratings for multispeed and variable-speed furnaces only determine the efficiency of the actual furnace. If you are upgrading your old, mid-efficiency furnace to a high-efficiency furnace, you should make sure that your Perkasie home is properly insulated and sealed. You could also consider upgrading any older doors and windows to more efficient double-paned ones, or you can also install storm doors and windows.

What to Check If Your Furnace Isn’t Lighting

Friday, January 13th, 2012

If your furnace isn’t lighting properly and your family is starting to suffer because of it, there are a number of possible problems you should check for before calling a Harleysville professional. Some of these issues can be fixed quickly by you while others may be signs of a serious problem that needs professional attention right away.

Checking the Pilot Light

If you have a gas furnace, the first step is to check the pilot light and ensure it is still working properly. If the pilot light is still on but goes out when you try to light the furnace or simply won’t stay on when you relight it, you may need to have the gas valve replaced. In some cases, it is as simple as the pilot light not being large enough and the gas blowing out the light.

This happens when gas enters the chamber and doesn’t ignite right away. When it does ignite, which happens after more gas enters the chamber, the extra force of the ignition will blow out the light. This is still a problem and should be inspected to ensure you don’t have any potential gas related issues.

Still Not Lighting

If you don’t have a pilot light or the unit still isn’t lighting, it may be an electrical issue. Electrical ignitions for gas furnaces should spark when the thermostat is turned on, so if it doesn’t you know that the switch or relay are bad.

If you smell gas or anything similar in the room where the furnace is located, you should immediately turn off the unit and call your gas company, followed by a technician. There could be a leak causing low pressure that results in your pilot light going out. Whatever the case, you need someone to look at it immediately.

Your furnace should always turn on when you flip the switch and if it does not, assume there is a problem. If you cannot find the problem yourself and easily fix it, you should call a Harleysville professional. The risk inherent in an improperly working furnace (especially gas or oil) is too high to ignore.

Causes of Delayed Furnace Ignition

Wednesday, January 11th, 2012

Delayed ignition is usually accompanied by a loud banging or booming sound that resembles a small explosion in your gas appliance. In your New Britain home’s furnace, this can be terrifying and should never be ignored.

What Causes Delayed Ignition

Delayed ignition usually happens when you first turn on your furnace, often after a long delay between use, so usually early in the fall or late in the spring when you don’t necessarily have it on every day of the week.

What happens is moisture builds up over the course of a period of inactivity and begins to corrode the firebox in your furnace. That corrosion builds up to the point that it starts to block the ports that feed gas into the burners. When these ports get blocked, the burners down the line cannot light and when you flip the switch, they won’t light immediately.

Of course, while rust and corrosion are a risk, lint and dust can be equally problematic (and are more common if you don’t have your furnace cleaned properly each fall). Sulfur build up is also a possibility, as it is left behind by burning natural gas. It will appear as a layer of white on the surface of the burners or the pilot light.

When all of this happens and the ports are not cleaned properly, gas will build up in the chamber after it is turned on and, when it finally ignites, create the small boom sound. It doesn’t just sound like an explosion – it is one – and if ignored, it can become incredibly dangerous.

Solving the Problem

Delayed furnace ignition is an easy problem to avoid. All you need to do is have your furnace cleaned properly before turning it on each fall. A New Britain heating technician will clean the burners and ports and remove any dust, lint, rust or sulfur buildup that might block ignition and cause a delay.

When replacing your furnace, look for a device with corrosion resistant materials. You can learn more about these when it comes time to replace your furnace from a technician. Most importantly, be careful. It may be a small problem now, but if left to build up over time, that small boom can become a much larger one.

What Is a Gravity Furnace?

Monday, January 9th, 2012

A long time ago, gravity furnaces were a very popular means of heating a home. Instead of pressurizing and blowing air through vents to each room of your Buckingham home, a gravity furnace used gravity to move warm air between rooms.

The operation of these furnaces is pretty simple. When turned on, the furnace, which is located in your basement, burns fuel like gas or oil and produces heat. That heat is vented through ductwork to the top level of your home using the natural properties of gravity (hot air rises). The hot air exits vents as it travels up in the home and releases heat into the room.

Why to Replace a Gravity Furnace

While gravity furnaces can work nearly forever and have very few mechanical problems, they are incredibly expensive to operate and take up a lot of space. Due to the sheer volume of ducts needed to distribute air throughout your home and the cost of heating enough air to ensure it rises properly, you’re dealing with a heating efficiency of 50% or lower.

In fact, about half the energy you consume to heat air in a gravity furnace gets pumped straight out through the chimney. It’s a complete waste of money and a replacement will start saving you money almost immediately.

Newer furnaces have efficiency ratings of up to 95% which makes them nearly twice as efficient as gravity furnaces. Additionally, they take up less space and with modern components, you can install newer devices like zone controls, electronic readout and display and more. It’s a fantastic way to enjoy steady, reliable heat in your home without having to invest a fortune in the fuel needed to operate it.

Comfort Matters

Another thing to consider is the comfort level of your home. Because gravity furnaces release warm air through the middle of the house and cold air comes back down along the walls, homes that have them are rarely comfortable except in the middle of the house. Forced air furnaces with blower fans are much more efficient at distributing heated air and matching the thermostat settings you select.

What Does a Furnace Fan Limit Switch Do?

Friday, January 6th, 2012

When researching your Plymouth Meeting furnace and potential problems it might have, you’ve probably run across a few references to the fan limit switch. And while you know that it can break in a number of ways, do you know what the switch does and what you should look for when checking your furnace its air handler for problems?

What the Limit Switch Does

To put it very simply, the furnace fan limit switch is a control that tells your furnace’s fan when to turn on and off. So, when the furnace isn’t on, it tells the blower not to operate (and send cold air into your home) and when the furnace is on, it tells the blower to turn on and start circulating the warm air.

While the primary function of the limit switch is to turn the blower fan on and off, it also has a safety role. When the temperature in the air supply plenum gets too hot, the limit switch turns off the furnace boiler to keep there from being any damage from overheating. This is handy if there is a blockage in the air vents or the controls are messed up due to water damage or improper adjustments to the settings.

Looking for Problems

Most of the time, when there is an issue with your furnace turning off or on frequently, the limit switch is one of the first things you will check. Because the switch is electronic and is attached to a thermostat which measures temperature in the air supply plenum, a small problem can result in it not working properly. So, you can easily check it by temporarily bypassing the switch and seeing if your device turns on or off properly.

In many cases, if the limit switch is the problem, you will still need to call a Plymouth Meeting professional for replacement, but you can avoid a lot of headaches related to tracking down the source of the problem. If you suspect a limit switch problem, make sure to call someone immediately, because it does provide an important safety function and because without it your furnace won’t cycle on and off properly.
