Heat pumps as a newer heating alternative have been talked about a lot lately. If you need more information to decide whether air-to-water heat pumps are the right choice for you, read this text.

When we make a choice on how to heat ourselves during the winter, one of the most important factors is the cost of heating.

That’s why heat pumps stand out as a system with which you get significantly more energy than what it will cost you at the end of the month.

More precisely, the installation of a heat pump is a rather large expense at the start, but on that pays off many times over in the following years.

Air to water heat pumps: everything you wanted to know

What types of heat pumps are there?

We can differentiate heat pumps in various ways (power, features…), but the most common way is according to the energy type they use. This way, we have:

  • Air-to-water heat pumps
  • Water-to-water heat pumps
  • Ground-to-water heat pumps
  • Air-to-air heat pumps

Why do we single out the air-to-water heat pumps?

Simply put – the installation of this type of heat pump requires the least investment, and the heating effects are just as good as with the other types.

In addition, this system can be applied to 90% of all structures.

How does an air-to-water heat pump work?

Basically, every heat pump takes energy from an outside environment and transfers it to the inside of the building – on the same principle as an air conditioner. It even resembles an air conditioner – it has an outdoor and an indoor unit.

So, by its very name we understand that this heat pump system uses outside air as an energy source. That cycle starts when R32 gas in a liquid state enters the evaporator, where it changes its aggregate state in contact with the external temperature and evaporates. Then, in the form of gas, it reaches the compressor, which compresses it and thereby heats it up.

Heated, the gas then goes to the condenser where it becomes liquid again and through the exchanger in the Hydro Module it transfers the heat to water for heating, then the gas returns and the cycle starts all over again.

It is also important to note that the R32 gas used by the Tesla air-water heat pump is eco friendly.

What’s the secret of their cost effectiveness?

Air to water heat pumps: everything you wanted to know

As we have already mentioned, it takes more investment to install a heat pump system than a classic heating system. However, with proper use, you will use up to 5 times less energy than by heating your home with any other heating system. This means – significantly smaller monthly bills.

An example: for 1kw of electricity, up to 5kw of heat energy is obtained, which makes the heat pump very efficient compared to electric heating units, where the ratio is 1:1.

However, it is important to note that the operation and efficiency of the heat pump depends on a number of factors, such as insulation, the way your home was built, the materials that used, etc.

To sum up: heat pumps save up to 75% of heating energy compared to conventional heating systems.

How much space can an air-to-water pump heat?

The air-to-water heat pump has a wide operating temperature range and can even heat a space of a few hundred square meters!

And what about the hot water?

If you use a Tesla air-to-water heat pump, you have the option of connecting the water heater to the heating system, which uses energy to heat water for the household. Here is another opportunity to save electricity.

Air to water heat pumps: everything you wanted to knowWhat if I already have heating elements in my home?

Heat pumps support a wide range of internal heating elements (radiators, underfloor heating, fan coil…). You can use existing heating elements and won’t have to make additional investments when upgrading.

If you have already decided on an air-to-water heat pump, it is important to know this:

– In addition to all the above-mentioned benefits, thanks to the powerful compressor, large heat exchanger and high-precision system controls, the Tesla heat pump is able to maintain normal operating functions at different temperatures. The cooling functions will work properly at outdoor temperatures up to 46℃, the heating will work normally even at -28℃, while the maximum water outlet temperature is 60℃.
