Kellogg Heating Q/A: What Exactly Are High Efficiency Boilers?

Monday, February 13th, 2012

As a Kellogg resident you have already read plenty about how energy costs are rising. You know plenty well that heating your home is a substantial expense, and that the cost of running a boiler is constantly on the rise. That whole array of topics has been more than adequately covered.

So rather than spend more time telling you what you already know, this post is about one of the solutions to combat the high costs of home heating: high efficiency boilers. As technology has gotten better, so have boilers become more efficient at providing heat. It stands to reason that a more efficient boiler is one that costs less to run…but what does “efficient” really mean in the context of boilers? What makes a boiler “high efficiency”?

What Is a High Efficiency Boiler?

All boilers are rated according to a standardized system of rating efficiency, called the Annual Fuel Utilization Efficiency (AFUE). Essentially, this rating tells you how much heat energy is produced by a boiler compared to how much energy it draws. The higher a boiler’s AFUE rating, the more efficient it is.

For a boiler to be called high efficiency, it must carry an AFUE of at least 90%. For basis of comparison, older systems carry an AFUE of about 70%, while mid-efficiency systems run at about 82%.

In addition, a high efficiency system has a second heat exchanger for capturing and condensing flue gases, as well as a closed combustion system.

These three things — an AFUE of 90% or above, condensing flue gases and closed combustion – define a so-called “high efficiency” boiler.

Getting More Efficient

To go the high efficiency route, the most obvious option is to replace your current boiler with a high efficiency unit. But what if you have a fairly new boiler that is not ready to be replaced yet?

In that case, you can retrofit your existing boiler with high efficiency equipment. It won’t be quite the same as getting a top-of-the-line high efficiency boiler, but it will produce high efficiency results without costing as much.

The initial investment in a high efficiency boiler can be costly, but the savings over time in heating bills make it well worth the expense.  Call ACI NW with any questions about boilers.

Understanding the Heat Pump Defrost Cycle: A Guide from Greenacres

Friday, February 10th, 2012

If your Greenacres home has a heat pump, you’ll want to understand the defrost cycle to help you maintain your heat pump and troubleshoot repairs. While this is a basic guide, you should call a qualified HVAC technician if you experience major issues with your heat pump.

During the winter when a heat pump is heating your home, the cooler outdoor air that’s pumped in and heated may have excess moisture. The outdoor coil evaporates this moisture, but under certain weather conditions, frost can accumulate on the coil and decrease the overall efficiency of the heat pump.  To help reduce the potential for damage from the frost, heat pumps are manufactured with a defrost cycle to melt the frost from the outdoor coil. The defrost cycle occurs often during heavy frost conditions, so check weather reports if your defrost cycle seems to be running often.

At the beginning of the defrost cycle, the heat pump switches to the cooling mode and temporarily warms up the outdoor coil until it reaches somewhere around 60° F to melt the frost from the coil. To increase the temperature of the coil, the outdoor fan is prevented from turning on until the outdoor coil reaches the desired temperature. Weather conditions and the timing device both affect the amount of time it takes for the heat pump to move through the entire defrost cycle.

In older homes, electric heating pumps are sometimes installed to prevent cool air from being distributed throughout the home. This element will turn on with the defrost cycle and shut down the blower fan inside the house. If you have an older heat pump, you may want to consider upgrading to a more efficient model.

Call ACI NW any time if you have questions about the defrost cycle for the heat pump in your Greenacres home.

How Often Should I Replace My Furnace Filter?

Monday, February 6th, 2012

Just like the filter in your air conditioner, replacing your furnace filter is the key to a healthy and comfortable Coeur d’Alene home. By keeping a good filter replacement schedule, you will reduce wear and tear to the furnace and keep your home warm, while keeping your family healthy and controlling energy costs all winter.

But when does your furnace filter need to be changed? Well, each system is different, but there are some general guidelines and recommendations to follow that can help you keep it all straight and stay on top of your furnace filter situation.

Conventional Wisdom

The long-standing rule of thumb on furnace filters is to change them every month. This is good practice if you are using older fiberglass filters, but for newer, more efficient filters, you should do it a little differently. These should be inspected and cleaned at least once a month, but you may need to replace them that frequently also.

Sometimes it is a little more complicated than these general guidelines, so it pays to be aware of some factors and conditions in your home that may affect how frequently you need to change your filter.

Things to Consider

As mentioned above, the first thing to consider is the efficiency of the filter. Because new filters are so efficient, when they get dirty or clogged with dust and debris, they actually restrict airflow, making your furnace bog down and work harder. So, it is important to stay on top of a monthly inspection and cleaning schedule with these filters.

Also take into account indoor air quality and sources of allergens both inside and outside your home. If you live in an area with a lot of pollutants in the air, you’ll want to replace your filters often to keep those out of your home. If you own a lot of pets, the dander and hair will wind up in your furnace filter and you may have to replace it more often.

Complicated enough for you? It doesn’t have to be. Simplify the whole process by doing the following: check your filter monthly and be prepared to change it that often, clean high-efficiency filters regularly, replace the filter at least every three months and again at the start of heating season.

If you do those things at a minimum, you will be in pretty good shape.

Things Your Air Filter Can’t Filter in Mead

Friday, February 3rd, 2012

Air filters are great to have in your Mead home. Many people who own air filters, especially those who suffer from allergies or asthma, swear by them as being very beneficial to their health and general well-being. They help you feel comfortable knowing that your air is clean and fresh.

But how confident should you be in your air filter? Is there anything your air filter is missing? Can you be sure that your air is as clean as can be?

Well, all air filters have limitations, and many do particularly well at trapping and removing certain types of air pollutants, but at the expense of letting others pass. What your air filter can and cannot do depends on what kind of equipment you have.

A conventional air filter, like the pleated kind you may have in your air conditioner, is designed to trap particles in the air. Pollen, dust, dander and other small but solid pollutants and irritants get trapped in their close-knit fibers. The thing to pay attention here is the filter’s HEPA rating—the higher it is, the smaller the particles it can trap. So, if you are using a lower rated filter, you may be trapping pollen but still breathing in smoke particles. Also, sometimes large, heavy particles settle before reaching the filter and can’t be trapped.

A less common option is the gas-phase air filter. As you may guess from the name, these filters are meant to filter out harmful gases in the air. They do not trap particles and usually have a short life, so they need to be replaced frequently.

In addition to filters, there are other air cleaning options like ultraviolet germicidal (UVG) lights and photocatalytic oxidation (PCO) cleaners. PCOs are meant to filter out harmful gases, but have limited use in homes. UVG lights use radiation that is harmless to people but deadly to microorganisms to pure air of bacteria and other pathogens.

In sum, if you are concerned about the quality of the air in your home, the best strategy is probably to use multiple solutions, such as a combination of an air filter and UVG lights, in order to get rid of as many pollutants as possible. Keep in mind, though, that no system is perfect in keeping everything out of your air.

Heat pump maintenance, the right way

Wednesday, February 1st, 2012

Heating and cooling your Spokane County home is a priority. You need your home and family to be comfortable all year round, so you either got or are considering a heat pump. These machines are great because under the right circumstances, they are essentially all-inclusive and incredibly efficient solutions for all your home heating and cooling needs.

Notice the “under the right circumstances” part. A number of things have to be considered when choosing a heat pump, such as the climate and the size of your home. But these are not the only circumstances that influence how well your heat pump works for you. Proper heating system maintenance is a vital component of heat pump ownership, ensuring that you get the best performance out of your heat pump for the longest time possible.

A major part of properly maintaining any machine is to keep it clean. A heat pump is no exception. Dirt and dust can affect the efficiency of your heat pump, as well as speed up corrosion problems. Keep the compressor and coils clean. Check them monthly or so and remove any accumulated dirt. Also, consistently check and change filters according to the manufacturer’s recommendations.

Simple cleaning is an easy and effective first step to heat pump maintenance, but there are some things that you just won’t be able to do on your own. For more intensive maintenance, it is best to call in a professional for an annual inspection.

During a routine maintenance check of your heat pump, a technician will inspect the whole heat pump system for problems. He will clean the compressor and coils, tighten any connections that may have loosened up and change the filters as needed. In addition, a skilled technician will be able to detect any early signs of trouble and make necessary repairs to prevent break downs. These small repairs can prevent big problems later on, thereby preventing some serious discomfort and a possible big expense.

If you are considering a heat pump as a heating and cooling solution for your home, great. If you have already decided on one and had it installed, congratulations on making a smart decision. Now, make another smart decision to protect that investment by keeping your new heat pump properly maintained.

Electric Furnace Maintenance Tips

Monday, January 30th, 2012

Electric furnaces are clean – but homeowners pay for that cleanliness with high utility bills. Depending on the area of the country, electric bills can rival those of gas, oil, or propane. So it is only natural to assume that an efficiently running electric furnace is a must for homeowners who are looking to keep their energy costs down.

Electric furnaces are fairly simple machines. They use heating elements to warm the air, which is then distributed through the ventilation system via a fan or blower. The heating element is made up of a metal wire that is heated by normal electrical current. The element is used to warm or heat something, much like the function of an oven or toaster. Their operation is fairly simple – either they work or they don’t.

When a heating element fails it is usually because it is broken, bend, or misshapen. When that happens, it is time to replace it. You can do some preventive maintenance with a visual inspection of your heating elements. If your inspection does not reveal any problems, you can test the element for continuity. You should know how to use an ohmmeter to test it or ask a professional heating technician to check the elements for you.

Speaking of visual inspection, you can do a quick check for any frayed or damaged wires, which can be a source for wasted electricity, too. Another way to ensure that your electric furnace is running efficiently is to replace or clean your furnace filters on a regular basis. A clogged filter can make a furnace work harder and lead to premature mechanical failure.

And obviously, if the furnace is not working it is best to check for any blown fuses or tripped circuit breakers in the main electrical panel box. If you find one, make sure you replace it with another of the correct amperage.

Lastly, check to make sure the blower motor is operating correctly. You can have perfectly working elements but if the blower can’t push the warm air through your ventilation system, then all of the steps to ensure the electricity is working are for naught. You can usually hear a noisy motor or smell one that isn’t working improperly. Check it on a regular basis and check the fan belt for any damage or slippage, too.

As you have read, an electric furnace is a very simple machine with simple working parts. Maintaining it is just as simple.

Bayview Heating Tip: Most Energy Efficient Upgrades for Your Home

Friday, January 27th, 2012

Before you decide which upgrades will make your Bayview home more efficient, it would be best to get a home energy audit. You can do this yourself with a few simple tests, or you can hire a professional auditor. The auditor will use advanced equipment and techniques, such as blower doors and infrared cameras, to detect air leaks and places that need more insulation.

When your home is properly insulated and sealed, here are some upgrades you’ll want to think about to make your home more efficient.

High-Efficiency Furnaces & Heat Pumps

If you have an old single-stage furnace, it is time to upgrade. These furnaces were designed to run on two settings—either off or on, and when they are on, they run at full speed. Not only do they lose heat this way, but they also take longer to warm up your home. The new two-speed and multispeed models run at lower speeds to maintain a constant temperature. You can also buy ones with variable-speed blowers that operate on various speeds, which are the most efficient. Heat pumps are a good option if you need both heat and A/C in your home. While most heat pumps are manufactured to be efficient by design, the newer models are the most efficient way to heat and cool your home. If you have a heat pump older than 15 years, talk to an HVAC technician about a heat pump replacement.

Tankless Water Heaters

Tankless water heaters heat your water with individual units located near hot water applications. You also have the option of installing a single, whole-home tankless water heater, or for appliances that use more hot water, such as dishwashers and washing machines, you can install tankless models just for their use.

Water-Saving Toilets & Low-flow Plumbing Fixtures

Duel flush, or water-saving toilets are an excellent choice for an upgrade if you want to save water. These toilets use less water overall, and you have the option of using more or less water each time you flush. Installing low flow faucets and fixtures can also provide up to 60% in utility savings. Low flow plumbing fixtures reduce the flow rate for each fixture or application, which reduces the overall amount water used in the home. These are a good option if you’ve installed a tankless water heating system. Your tankless water heaters will be more efficient if the sum of the flow rate total for every fixture in the home is lower.

Hope Heating Installation Guide: How to Install a Programmable Thermostat

Wednesday, January 25th, 2012

Programmable thermostats are one of the best ways to save on heating costs, especially if you have a hard time remembering to turn down the heat in your Hope home. Installing a programmable thermostat will allow you to set the times you want the heat turned up or down. Not only will this make heating your home more consistent and save energy, but it will also allow you to tailor your heating needs to your schedule.

For instance, you can set the thermostat to turn on before you get up in the morning so that the house is already warm when you get out of bed, and conversely, set it to turn down after you go to bed or leave the house for work. Depending on the brand and setting options, programmable thermostats are relatively inexpensive and easy to install.

Although all styles are slightly different, here are some basic instructions that show you how easy it is to install a programmable thermostat.  Remember, this is only a general guide; always check the instructions inside the packaging of your new thermostat before you install it, or check with an electrician.

1. Remove the Old Thermostat

Before you remove the old thermostat, check to see where it’s mounted. If it’s mounted to an electrical box, the voltage used to power the old thermostat may not be compatible with the new one. Ask a certified electrician or heating technician if you aren’t sure.

CUT THE POWER TO THE HEATING SYSTEM TO AVOID ELECTRIC SHOCK. You should always turn off the main power supply to your heating system before installing any new thermostat. If you aren’t sure how to do this, ask your HVAC contractor. Once you unscrew the mounting plate for the old thermostat, just unhook the wires. Don’t throw an old mercury controlled thermostat. You should ask your local waste management facility how to properly dispose of mercury products.

2. Locate all Wires

Wrap the loose wires around a pencil to keep the wires from falling back into the wall. Identify and label each corresponding wire with a letter (do not use color coding since this is not always accurate). Strip the plastic off the ends of the wires about ¼ inch if you need to.

3. Install and Insulate Wallplate

If the area around the new wallplate is larger than the plate, insulate the hole with non-flammable insulation. Take the wallplate off the programmable thermostat and hold it against the wall to mark the screw holes with a pencil. Pull the wires through the large opening at the bottom and screw the plate to the wall.

4. Wiring

Make sure you are comfortable with wiring before you attempt to do any electrical installations. Check the manual for your programmable thermostat for instructions on wiring that specific model. In general, you’ll want to make sure you match the wire labels with the corresponding terminals on the thermostat. Sometimes there will be extra wires that aren’t needed. Always test it before completing the installation. Don’t forget the battery!

5. Install the Faceplate

Once you have it wired correctly, all you need to do is align the brackets on the faceplate with the corresponding slots on the wallplate and fasten the faceplate to the rest of the mounting. Lastly, tighten the screw at the bottom of the thermostat to hold it in place.

Greenacres Heating Installation Question: How Does a Heat Pump Work?

Monday, January 23rd, 2012

If you’re in the market for a new home heating and cooling system in Greenacres, a heat pump is definitely an option worth considering. However, while the popularity of these systems is growing rapidly, many people still don’t understand what they’re all about. Before you go out and get yourself a new home comfort system, you should make sure you really know what you’re looking at.

As their name suggests, heat pumps move heat from one location to another. However, their name can be misleading as well. Heat pumps are able to both heat your home in the winter and keep it cool in the summer by taking heat from the air in one place and sending it to another.

For example, your heat pump will remove the heat from your indoor air in the summer and pump it outside to keep your home cool. In the winter, the process is reversed, and the heat pump gathers heat from the outdoor air and pumps it inside to keep you house warm.

Of course, it’s not hard to see how the air inside your home in the summer has heat in it. But the outdoor air in the winter is cold. So how does a heat pump heat your house with cold air? Well, the truth is that there is almost always some heat in the air, no matter how cold it seems to you and me.

In fact, the temperature would have to drop well into the negative range before there was absolutely no heat to be found in the air. And heat pumps are specially designed to find that heat and collect it.

Basically all heat pumps work on this principle. However, they can’t keep your house comfortable all on their own. Heat pumps are usually installed as part of a complete home heating and cooling system. This means they’ll be paired with an air handler that can circulate the temperature controlled air throughout your Greenacres house.

There are also some heat pumps that supplement the amount of heat they’re able to pull out of the air by heating it as it passes through. These types of heat pumps are often more effective in cooler areas, but because they require more energy to actually generate heat, they’re not typically as energy efficient as models that rely on their ability to get heat only out of the air.
