Pros and Cons of Various Heating Systems in Cedar

Friday, December 9th, 2011

When it comes time to install a new heating system in your Cedar home, there are a lot of options to consider. Many people get overwhelmed when confronted with all of the furnaces, boilers and heat pumps on the market these days. So, to help you get a handle on what each has to offer and which will offer you the best benefits, here is an overview of the modern heating system market.

Furnaces

Furnaces are the core of a forced air heating system and use gas, oil or electricity to heat air which is then circulated through your home by a blower in your air handler. Furnaces are among the most fuel efficient heating systems on the market today with options available at up to 95% AFUE (meaning it uses up to 95% of the fuel consumed to produce heat). They are also inexpensive to install and while they don’t last quite as long as boilers, they are highly efficient when well cared for.

Boilers

Boilers use gas, oil or electricity to heat water or steam which is then circulated through your home into radiators or baseboard heaters. The heated water or steam releases heat into your home and heats it in turn. While not quite as energy efficient as a high efficiency furnace, boiler heat is perfect for homes with existing radiators and no room for vents and ductwork. It also has less of an impact on indoor air quality since there is no air movement and boilers tend to last a very long time when well maintained.

Heat Pumps

Heat pumps are becoming increasingly popular, especially in milder climates where it rarely gets below 40 degrees F. A heat pump uses the same technology as an air conditioner to extract heat from outside using a compressor, evaporator coils, and condenser coils with refrigerant.

It is most efficient in the spring and fall when temperatures are mild, but it uses much less energy than either a boiler or furnace and it can be used in the summer to cool your home. When properly maintained, a heat pump will last 10-20 years and save quite a bit of money, though it is recommended that you have an emergency heat source for days when the temperature outside gets below 40 degrees F.

Furnace vs. Heat Pump: Some Pointers from Golden Valley

Wednesday, November 9th, 2011

If you’re preparing to replace your existing heating system in your Golden Valley home, you may very well be struggling with the question of whether to go with a furnace or a heat pump for your future home heating needs. Each of these systems have their own advantages and drawbacks, and once you’ve narrowed it down to one type or the other, you’ll still have a pretty wide variety of products to choose from.

Furnaces are still the most popular type of home heating equipment on the market. You can get furnaces that run on gas, oil or electricity, although gas furnaces are by far the most common type of furnace around these days. The latest models are extremely energy efficient, with AFUE ratings reaching into the high 90%s.

Like heat pumps, furnaces use ducts to transfer heated air throughout your home. They typically require regular maintenance once every year or two depending on the type of furnace you have, and they can be expected to last anywhere from 15 to 25 years when properly maintained. Most modern furnaces are also made to be compatible with a central air conditioning or cooling system as well.

Heat pumps, on the other hand, don’t generate the heat that they circulate throughout your house. Instead they are able to extract the heat from the air outside and pump it inside. This means that they use much less energy than even the most energy efficient furnaces.

However, heat pumps are only capable of heating your house comfortably when the outside temperature is above freezing. If you live in an area with particularly long and frigid winters, you’ll probably find that you need to supplement your heat pump with another heat source. Because of this, it actually makes little sense to use a heat pump in more extreme climates.

On the other hand, if you live in an area with relatively mild winters, heat pumps can be a great option. They provide a constant flow of warm air to all parts of your home and can also keep you house cool during hot summer months. To cool your home, heat pumps simply reverse the process they use to warm it. They take the heat out of your indoor air and pump it outside. This is a very effective home cooling method and makes heat pumps a great solution for year round comfort.

Do I Need to Supplement my Heat Pump with Another Heating System? A Question from Roseville

Wednesday, October 26th, 2011

People often turn to heat pumps as a solution for their Roseville home heating and cooling needs because they want a single, all-inclusive system that covers all the bases. The convenience and simplicity is part of the allure of choosing a heat pump to begin with.

However, it’s not always that simple. There are situations where a heat pump is not enough to handle the needs of the whole home. This doesn’t necessarily mean that the whole idea goes out the window, but the heat pump may need some help in the form of a supplementary heating supply.

Here are some reasons/situations that may call for a supplemental heat source in addition to a heat pump:

  1. A  Cold Climate – Although heat pumps can serve as the primary heating system when temperatures drop as low as 30 degrees Fahrenheit, they have trouble keeping up when the cold snap lasts longer than a few days. In any climate where temperatures dip below this mark for a length of time, a supplemental heating system is recommended.
  2. A Large Home – Heat pumps come in many different sizes, but if yours does not have the capacity to match the size of your home, then it won’t be able to heat the whole house. It’s as simple as that. If you are installing a new heat pump, be sure to get one that is properly sized. But, if you have an existing heat pump that is overmatched by your home’s size, simply supplementing it may be the easiest solution.
  3. The Power Goes Out – A Heat pumps’ use of electricity is a benefit in most situations, but unfortunately it means they are helpless when the power goes out. To avoid suffering in the winter chill when a blizzard takes out a local power line, have a backup/supplemental heat source on hand to use until the power comes back on.

Those are a few situations you may encounter in which supplementing a heat pump is a good idea. Remember, though, that each situation is different. When installing a new heat pump, consult with the professional installer beforehand to see if you should also have a supplemental heat system in addition to the heat pump. This is especially important if you live a cold climate.

Heat Pumps and Energy Efficiency: A Tip from Ramsey

Monday, October 24th, 2011

Heat pumps offer a number of great benefits. For one, they are inclusive heating and cooling solutions, so they can maintain your Ramsey home at a comfortable temperature year round without the need for an additional system.

They run on electricity, so you don’t have to worry about the inconvenience of additional bills and keeping a fuel supply around. They are also quiet and relatively easy to maintain—the list goes on and on. The point is, provided you live in a climate where heat pumps can operate properly, they make for great heating and cooling options.

One other huge advantage of heat pumps is that they are very energy efficient, often much more so than other heating and cooling options. For one, the heating efficiency of heat pumps can range from 150-300%, meaning that the amount of heat energy they are able to produce is 1.5 to 3 times greater than the amount of electricity they draw to do it. That is an incredibly efficient exchange.

The United States Environmental Protection Agency awards the EnergyStar to devices and appliances that surpass energy efficiency guidelines. Heat pumps that have earned the EnergyStar are even more efficient than their brethren, sometimes by as much as 9%, according to the EPA. If you have an older heat pump in your home already, a newer EnergyStar rated model may be as much as 20% more efficient.

While these numbers by themselves may not seem Earth shattering, consider two things. First, in an age of constantly escalating energy costs, any savings are welcome. Second, rewarding energy efficient homes has been a focus of the federal government for a few years. To that end, homes with EnergyStar rated heat pumps installed may be eligible for a federal tax credit of up to 30%. So, not only do these devices help you save on your bills, but on your taxes as well.

The benefits of heat pumps are numerous, but perhaps none is a bigger plus than their extremely efficient use of energy. You can save electricity and save money, all while keeping your home comfortable year round.

If you are considering a heat pump for your home, these benefits are important to keep in mind while making your decision. For more information, talk to your local contractor.

Heat Pumps and Zone Control Systems: A Guide from Champlin

Wednesday, October 19th, 2011

When you’re putting a heat pump in your Champlin home, it may also be a great time to look into having a zone control system put in as well. These types of systems can do a lot to both lower your energy bills and make your home as comfortable as possible throughout the year.

Zone control systems actually allow you to set different temperatures in different parts of your home. They use a system of dampers to direct more heat to certain areas and less to others. For instance, you may like to keep the living room nice and cozy in the winter because you’re typically just lounging around when you’re in there.

When you’re working in the kitchen, on the other hand, you’re usually generating some heat yourself from the stove and oven, so you don’t need to keep the temperature quite as high as it is in other parts of the house in order for the kitchen to remain comfortable. Of course, in the summer, these situations are likely reversed, and a zone control system will allow you to adjust accordingly.

Having the type of refined temperature control that zone control systems provide can be beneficial on several levels. It certainly helps make your home more comfortable, but it can also make it easier to reduce some of your home heating and cooling costs because you don’t have to heat or cool your whole house to keep it that way.

Zone control systems can also be a great way to end those constant thermostat battles that tend to erupt from when certain members of the household prefer one temperature, while the rest of the people in the house are more comfortable with another.

If you’re thinking of integrating a zone control system with your heat pump, you should make sure that the heat pump you get is as compatible as possible with this type of system. Most heat pumps will, in fact, work with zone control systems, but certain types are better than others.

The most important thing to look at when you’re trying to find the best heat pump to fit with a zone control system is the type of compressor the unit has. Heat pumps are available with one-speed, two-speed and multi-speed compressors and this affects how well they work at part of a zone control system. For best results, it’s good to opt for a two-speed or multi-speed compressor when you’re installing a zone control system as well.

How Does a Heat Pump Work? A Question from Roseville

Monday, October 17th, 2011

If you’re in the market for a new home heating and cooling system in Roseville, 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 the 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.

Most Commonly Asked Questions About Heat Pumps: A Guide From Andover

Friday, September 30th, 2011

If you’re thinking about buying a new heat pump for your Andover home, chances are you have some questions about these types of products and how they work. In fact, because these types of home comfort systems are relatively new to a lot of people, there are a quite a few misconceptions out there about how effective and efficient they can be.

Recently we’ve gotten some good questions from our readers, so we thought we’d like to pass along the answers so that others can benefit from the information as well.

If I Buy a Heat Pump, Do I Have to Buy an Air Conditioner Too?

That heat pumps are only able to heat your home is probably one of the biggest misconceptions about this type of equipment. Heat pumps work by extracting heat from the air in one place and transferring it to another. That means that in the winter, your heat pump is able to heat your home by taking heat from the outdoor air and moving it inside.

However, in the summer, the heat pump is able to do the same thing only in reverse. When you switch on your heat pump’s cooling function, it will be able to take the heat out of your indoor air and transfer it outside. In this way, the same heat pump system can keep your home warm in the winter and cool in the summer without you needing to purchase an air conditioner or other supplemental comfort systems.

If I Choose a Heat Pump System, Will I Also Need to Install Supplemental Heat?

That depends on what the climate is like where you live and how warm you like to keep your home. In general, heat pumps can keep any home comfortable as long as the outdoor temperature is above 32°F or so. If the temperature outside drops below that, you may want to have some type of supplemental heating system just in case. However, a heat pump will still be able to provide some warmth at these lower temperatures and you may be able to keep yourself comfortable with a simple space heater or too.

Also, remember that these colder temperatures are most common at night when you would probably have turned your heat down anyway. As long as you live in a relatively moderate climate, heat pumps can do a great job of keeping your home comfortable all year long.
