If you need to cool or heat a home, an electric heat pump is probably your best bet. Their major advantage is that they allow owners to reduce their costs with heating by up to 30%, at least when you compare it with other popular solutions, like a gas furnace. Besides the fact that you can use it during the entire year, an electric heat pump also does a better job. A proper electric heat pump is capable of giving a constant temperature and heat flow, while a regular gas furnace will just bombard certain parts of the house with too much heat, so there are differences in temperature which can be uncomfortable. Another advantage of a pump of this type is that it doesn’t need an open flame to operate, so you don’t risk things like poisoning with carbon monoxide or fuel leaks, things which can appear when a regular furnace is used. A solar heat pump is a very nice example that is friendly to the environment.

Electric Heat Pump

When it comes to electric heat pumps, you will find that there are three major types available: geothermal, dual-fuel and air source models.

The models which are commonly found are the electric heat pumps with an air source. These are also split in two different types, the heat pumps with a split-system and the packaged heat pumps. A packaged heat pump has the advantage that the heat exchanger and the compressor don’t need to be inside the house. Instead, the house will be cooled or heated with the help of ductwork. As for the split system models, their advantage is that they’re more flexible when it comes to installing them, since the heat exchanger and the unit which handles the air inside are both separated from the outdoor exchanger or the compressor. A heat pump with an air source will measure its efficiency when it comes to heat with the help of HSPF (Performance Factor), going between 6.6 and 9.1 ratings. As for its efficiency when it comes to cooling, the SEER number is used (which is the Effiency Ratio) and it will usually go from 10 to 15.

The heat pump with dual-fuel will behave similar to a gas furnace, by circulating the heat in the entire house, in an even way. Even though an electric heat pump of this type will usually be more expensive than the normal cooling and heating systems, they have the advantage of being more economical, versatile and efficient. The heating systems of the geothermal type will circulate either refrigerant or water between the house’s heat pumps and a pipe network which is underground. When you compare this type of heating method, you will see that it is both cleaner than a normal method, non-allergenic, safe for the environment, comfortable and it’s also more durable.

One of the things which should be considered when you install an electric heat pump in a house is how much square footage is present in the house, how much wall insulation there is, how much ceiling, the area occupied by windows and a number of other things which can influence a heating system’s efficiency.

What is an electric heat pump

Curious to know what is an electric heat pump, how it works and why it’s so much more convenient than a central air conditioning unit? Read on and find out the answer to your questions.

Just like the name suggests, the heat pump works by pumping out the heat from a room, to the exterior of the house, or by pumping it in, from the exterior to the interior, depending on the season and its function at the time. Just like an air conditioner, you can use a heat pump to also work as a dehumidifier for the air from the interior of the house. The major advantage of a electric heat pump is that it doesn’t consume as much energy as other solutions and it offers quite a bit of cooling power during the summer.

One other thing which sets apart heat pumps from air conditioners is that instead of generating heat, they will simply move it. Thanks to the way they work, they are able to save over 30% of the energy which would be used by other devices. There are also some disadvantages, like the fact that during the winter the efficiency will be lower, since the air outside doesn’t have sufficient heat, so pumping heat inside from the outside is much harder. Because of this disadvantage, the ideal climate where you can use an electric heat pump should be at most moderate during the winter. This type of device is not recommended for use in areas with extreme winters.

When picking a heat pump, you should go with a model which has a compressor with two speeds, not one which has just one. Thanks to the two speeds, you will be able to choose to operate the heat pump in low speed mode, if you don’t need it to run at maximum power. You will be able to save energy this way. Another reason why they are recommended is because they work better with systems which have zone control. With the help of automatic dampers you can keep rooms in the house at different temperatures, depending on the preferences of people living in them.

Another thing to consider is whether the heat pump comes with a desuperheater integrated, which allows you to heat water with the help of waste heat. The efficiency of this device is up to four times better than what you could accomplish with a electric water heater.

Another way to pick between two units is by looking at the type of compressors which are used. The better choice is a model with scroll compressors, since they have the ability to compress the refrigerant of the unit. When compared with a unit with piston compressors, the one with scroll compressors can give up to 15% extra air that is warm.

The final thing to look at when you pick an electric heat pump is what SEER rating it has, since this tells you just how energy efficient it is.

Heat Pump Efficiency

If you’re interested in alternative ways to cool down or heat up a house, you might want to look at the heat pump efficiency. There are a number of different ways that one can measure the efficiency of the heat pump, actually four total and you can decide for yourself which method is best for you.

Heat Pumps

Read on to find out more about heat pump efficiency and how it can be measured and interpreted.

One of the methods available to measure the heat pump efficiency is by comparing how much energy is delivered and how much energy is consumed by the solar heat pump. In this case and in general, when it comes to heat pump efficiency you want the number to be as high as possible.

There is one type of measurement which is the most common one used right now and it’s COP, which means Coefficient of Performance. The COP rating takes into consideration the ratio between the heat output in BTU and the electrical output in BTU. When you’re looking at either a ground source or water heat pump you can expect the rating to go from 3 to 5, depending on the model. When it comes to a heat pump with air source you will usually find models with COP ratings between 2 and 4. The COP rating of a heat pump with an air source will be smaller when the temperature drops outside. For this reason, it’s important to compare ratings when you know at what temperature they were measured.

Heat Pump Efficiency

One other method which can be used to find out the heat pump efficiency is EER, which stands for Energy Efficiency Ratio. It looks at how efficient the heat pump is when it comes to its cooling cycle. The same type of rating you will see in air conditioners. When it comes to the EER rating, you want a number which is more than 10.

When you look at the heat pump efficiency ratings you should remember that all these numbers which are displayed are tests done in laboratory or factory conditions. It’s quite likely that during real usage the numbers will be lower, since you probably don’t have ideal conditions. The weather can influence the number quite a bit, so ideally you want a rating which looks at calculations based on seasons. When it comes to season ratings, you should look either for SEER or HSPF numbers.

HSPF stands for the Heating Season Performance Factor and it’s a popular way of measuring the efficiency of a heating pump. As long as the HSPF rating is from 5 to 7, you know that you have a good heating pump.

As for the SEER rating, it stands for Season Energy Efficiency Ratio and it will measure how much cooling power it has, in BTUs. When it comes to SEER ratings, you want a heat pump efficiency which is from 8 to 10.

All in all, you can look at the heat pump efficiency either by measuring the performance coefficient, the heating functions or the cooling functions.

Solar Heat Pump

Generally, people don’t think of a solar heat pump when they hear about solar hot water. They will usually think it’s either a collector tank which is at the top of the roof and it’s heated by the sun, or they will think of solar panels.

The solar heat pump is quite different from the other types of sources for solar heat and the surprising thing about it is that it doesn’t require solar panels to be installed. These solar heat pumps manage to reduce your hot water bills quite a bit, since they will consume three times less energy than a regular water heater which is powered by electricity.

Heat Pumps

Solar Heat Pump A pump of this type resembles a bit a refrigerator in reverse. The pump will take the heat from the air found near the unit and it will transfer it to the heater and the water which is found inside, with the help of a system for heat exchange. When it comes to a pump of this type, you’re not actually talking about actual heat taken from outside. The pump will find heat even when the outside temperature is at -10 Celsius, so as long as you don’t have extreme winter conditions it will work just fine even when it’s cold.

How A Solar Heat Pump Works

The solar heat pumps works by drawing external air and getting it in the system of the pump, with the help of a fan. It goes in a evaporator which has a refrigerant which is in the piping. The name of the refrigerant which is use is R134a, a type of refrigerant which does not affect the ozone layer of the Earth in any way.

The boiling or evaporation point of the R134a is -26 Celsius. Even though that’s a very low temperature, it will still be able to boil the refrigerant solution. Since the air which is brought inside the pump is warmer than the boiling point of the refrigerant, the refrigerant will become a gas instead of a liquid as a result.

After that, the resulting gas will be pumped by the compressor, in a small valve, where it will be compressed. This process results in a lot of heat, which is transferred from the pipes to the water tank.

Since the heat is taken away from the pipes, the refrigerant will once again become liquid, so the cycle of the solar heat pump starts again.

Renewable Energy

There are quite a few advantages to a solar heat pump and the biggest one is that it’s renewable energy. In the long run you will find that there are huge expense savings when it comes to hot water costs. When you look at the actual numbers, you’ll notice that a pump of this type will make up to 5 times more renewable energy than what the unit needs to work.

Thanks to its smaller requirements of energy, this solar heat pump is very environmentally friendly and it will work well even when there are low temperatures outside.
