With advancements in technology, heat pumps are much more efficient these days than they were a few years ago. These new technologies have allowed the devices to recover heat better at colder temperatures. Most brands operate better now but still it is wise to do a heat pump comparison before making this major purchase.

The technological advancements have allowed these devices to be able to heat water for such uses as radiant floor heating, domestic water usage and multiple-zone forced air systems.

Purchasing a heat pump is a major investment as these units are not cheap. It will require quite a bit of research on the homeowners part. We can provide some basic heat pump comparison information to help you along the way. All heat pumps feature two specific ratings. The two ratings are the SEER (Seasonal Energy Efficiency Rating) and the HSPF (Heating Seasonal Performance Factor).

The SEER rating rates the cooling efficiency of the unit, the HSPF rating rates the heating ability of the unit. These are two main factors to consider when performing a heat pump comparison. The higher the rating, the more efficient the device is. One important point to note is that just because the unit has a high SEER rating, does not mean it will have a high HSPF rating.

Here is a good tip to keep in mind when doing a heat pump comparison. What will be your main usage of the heat pump? If the main usage is t o cool your home because you live in warm climate then focus on a pump that has a high SEER rating. If you live in an area that requires more heating than cooling, then focus on a heat pump that features a high HSPF rating.

A conventional heat pump has some standard features that are found on most makes and models. Most are much more energy efficient than normal types of heating. The standard conventional heat pump is cheaper than the newer Inverter heat pumps. If doing a heat pump comparison, make sure you compare conventional styles to conventional styles and inverter types to other inverter types. If you like you can compare conventional to inverter, just keep in mind the newer inverter types are more expensive.

Inverter heat pumps are new to the market and because of their sophisticated control features; you can have closer temperature control than the conventional style pumps. When doing a heat pump comparison, you will find that the inverter heat pumps are more advanced but they cost quite a bit more.

For people looking for alternatives to heat and cool their homes, look no further than heat pumps. They will also reduce your overall heating costs as well as these are energy efficient machines. These units will provide your home with year round heating and cooling. Some units are capable of providing supplementary hot water heating as well.

Heat pumps are best used in conjunction with your furnace to provide the most economical heating possible. There are several types available on the market and choosing a high efficiency unit over a low efficiency unit will save you even more money in energy savings. The EnerGuide system makes it much easier to select an energy efficient unit.

During the summer months, heat pumps function as a central air conditioner. The unit will remove heat from the home and vent it outside of the home. The unit will use a liquid refrigerant and pump it through coil tubing.

As the liquid moves through the coil, it will expand and change to a gas as it absorbs the heat from the air that surrounds the coil.

A blower will then push the air around the cooled coil and then it passes through the ducts into the house. In the winter, heat pumps will reverse this entire process. They extract heat from the cold air outside the home and pass it through the house.

The units work best when the outside temperature is between forty-five and fifty degrees Fahrenheit. Once the temperature drops to around the freezing mark, it is necessary to use an auxiliary heater to help supplement the output of the pump.

There are several factors to consider before you purchase a heat pump. Some of these factors include deciding on what your specific needs are for the pump.

You will also need to determine the size of the unit you need, along with deciding on which brand to choose. Try to stick with well-known heat pumps and one that offers a good warranty and one that provides good service as well.

I live in the Appalachian Mtns. & do not have the temp. extremes. Natural gas is not available, electricity is reasonably priced. My under const. home is 5500 sq. ft on 2 floors 1 of which is a walkout basement that is 1/2 exposed & frame.
I have 9′ ceilings & some vaulted ceilings. I have been told by 3 heat pump companies that I need a 5 ton down & at least a 5 up but two 3 ton units would be better.
I received a quote from a geothermal co. using one 4 ton unit.
One of the heat pump men said that he thinks geo requires twice the tonnage as air source.
The geo man checked R- ratings in the walls & fenestration values from the windows when he made his calculations, the heat pump guys mainly used sq. footage allowing for a well insulated house.
No one else in this area knows about geothermal.
Thanks for your input.

I am looking for a rating or maintenance history for the various manufacturers of heat pumps (not geothermal). I’ve checked Consumer Reports and didn’t have any luck. Doing some research online I got conflicting info (one person raves about brand X followed by some saying never buy brand X). Any info in appreciated.

“As time passes by our home equipments and tools somewhat break down for quite sometime due to excessive use or poor maintenance. When a situation such as this occurs, it is really a difficult problem to deal with. Especially if it’s a furnace repair in bc that you are about to do to fix your home heating system. That is a task that you definitely need to hand over to an expert who knows how to do the job in no time. Or else, accidents might happen and you wouldn’t want those to occur, right?

In performing heat pump repair you must be very knowledgeable on how it should be treated. To fix an equipment, for example, you must know how it is used and how it works. Same with heat pumps, you must know its use and how it works for your whole household heating system. A tip that you can use when doing repair on your heat pumps is to check your air filter first. Dust and moist waste might have clogged the air pipes and when that happens a simple cleaning tip will do. In instances that you noticed the air pipes can no longer last, better replace them with new ones. Sometimes it is better to spend a little to save in return. Also, you can have the guarantee that it won’t break down again.

Another heat equipment that might break down anytime in the household is a hot water tank bc. Many house owners surely experience situations like this and to handle problems same with a malfunctioning hot water tank, the best way to deal with it is call your resident water system repair personnel. An incident like this is very complicated so better give it up to a professional who can complete the work with just a snap. And afterwards better ask for some guidance when malfunctioning happens again so that you know what to do next time.

But what about if it’s a fireplace repair bc that you need to get fixed as soon as possible. Well, that is quite more difficult this time. A fireplace repair can also be a very dirty task to handle. This kind of household problem also need some proper guidance. Fixing it yourself might somehow be dangerous for you so better get someone who can fix it for you. Some fireplace problems only require proper cleaning. There are times that your chimney and air passages within the household are just clogged with unwanted dirt. So to prevent fireplace problems have your air ducts and chimneys checked in a monthly basis. This will serve as your monthly fireplace check up to prevent any problem that might happen. Also, you’ll have the chance to be knowledgeable on how to keep it clean all the time through the guidance of a pro.

Another thing that you might also need to face is a boiler repair in bc. Remember, dealing with this incidents need proper guidance. It is better to be safe than risk for consequences. If you can’t handle household heating problems like these stated above, don’t play heroic, better be practical and wise. There are people who knows more than you do in fixing problems such as all these. It is a wiser act to do to hand over all of those dangerous and risky malfunctioning problems so that accidents and unnecessary incidents can be prevented. “

If you have a pool, have you ever considered using a swimming pool heat pump to heat it? The efficiency of one of these units depends on the actual temperature outside. Since most pools are located outside, it is a logical choice to heat them in this manner. Many people still are not familiar with the operation of these machines. They do not actually generate heat; they just move it from one place to another.

A swimming pool heat pump will heat the pool to the desired temperature at an efficient cost. Just set the machine to the temperature you want and that is it. Thus, even if the weather is not that great, you can be assured that your pool is the right temperature for a enjoyable swim. These pumps work best when the weather is not too cold. They use the outside air as a free energy source.

A swimming pool heat pump will work in the same principle as an air conditioner or refrigerator but in reverse. The main mechanics of one of these units consists of a condenser, a ventilator, a heat exchanger and a compressor that incorporates a refrigerant.

The swimming pool heat pump will kick into action when the temperature of the water falls a degree or two below its desired setting. When the water reaches the temperature you have set on the machine, then it will automatically shut off until it is needed again. To find one of these units, check with a local heating and air conditioning supplier, they will likely carry heat pumps of varying sizes as well. Alternatively, you can search the internet for a company that may sell them online. However, purchasing them from a reputable dealer that is local to you is much more advised because you should have the supplier install the unit and provide you with the proper operating instructions.

In conclusion, heating your pool with a swimming pool heat pump is an energy efficient method of keeping your pool comfortable during the entire swim season.

Harwood E Woodpecker asked:


In this environmentally friendly world that we all live in certain steps have to be taken to ensure that there is still a world for people to inhabit in the future. People all over the world are looking at ways to help save energy and the world’s resources.

Household heating is a major consumer of energy so whatever can be developed to reduce the effect on the environment has got to be a step in the right direction.

By extracting heat from the ground or air (geothermal energy) and then compressing it to raise the temperature significantly, the heat generated can then be used for water or space heating.

Since there is quite a lot of heat energy in even very cold materials, heat pumps can use sources that appear to be very unpromising. For example, if the temperature of the air is 5 degrees C, that might appear to be too cold to extract any heat.

In reality 5 degrees C is pretty hot compared to absolute zero (-273 degrees C) and therefore an air source heat pump can produce useable heat all year round. Think of your deep freeze. Heat continues to be extracted from that area even though it’s well below freezing.

Heat pumps can use air, water and, increasingly commonly, the ground below your feet as a source of energy. Ground water is a particularly useful source of heat since it rarely gets much colder than 7 degrees C.

Unlike more conventional heating or air conditioning, heat pumps minimise pollution and fuel use.

By utilising entirely free and renewable geothermal sources of energy they are very low carbon and very economic to run. During hotter summer months the latest models can even be run in reverse to passively extract heat from inside a home and ‘dump it’ into the ground. This method of cooling is one of the lowest carbon and lowest energy approaches available.

For every unit of electrical power needed to extract the heat, up to six units of heat can be obtained. That’s right, heat pumps can be up to 600 per cent efficient.

It’s like buying a low-energy light bulb with an output rating of I00 watts but with an energy usage of only 20 watts. Remember, we spend very little on electricity for light bulbs in our homes compared to running our heating and hot water systems - so the savings are much greater.

The attraction of running a heating system this efficiently is obvious. It saves money and makes a real contribution towards a low or even zero carbon building and towards reducing the devastating impact of climate change.

It’s worth recalling how, by 2016, every new home in the UK will need to be rated ‘zero carbon’. Given that the law in this area is getting tougher all the time and the 2016 date is now fixed, new business opportunities are growing rapidly.

More and more heat pumps will be installed in the coming years which can only be good news for the environment. Pioneering companies have already gotten to grips with issues around the ground works required and enterprising trades people are discovering how they can become part of the future of our industry.

The next generation of heat pump technology that is even easier to install, and operate further reduces running costs and improves the already impressive efficiency which will make the models of the future even more appealing to the mass market.

These will offer air, water and ground source heat pumps to suit all household heating needs, helping to reduce the cost of heating water for your bath as well as heating the whole house during the colder months.

In addition to being powerful systems in their own right the heat pumps of the future even come ready to connect to a solar heating system, complete with flat-panel collector array and solar cylinder, providing an integration of solar energy and heat pump for domestic hot water and central heating.

Heat pumps will make a huge difference to the way we heat our homes as well as making a big difference, for the better on the environment.
