Air-to-water heat pump – MV-Jäähdytys

An air-to-water heat pump is an excellent solution, especially in cases where it is not possible to
install horizontal piping required for ground source heat or a heat well. This may be due to various reasons,
such as the property being located in a groundwater area or the need to reduce investment costs.
At our company, we specialize in installing and servicing air-to-water heat pumps across Finland.

Why to choose air-to-water heat?

An air-to-water heat pump is suitable as the main heating system of a house.
You will save a lot of money. The heat always comes from the outside air and then it is transferred to the water.
The air-to-water heat pump is often a cheaper investment than a ground source heat pump is.
The air-to-water heat pump can also be connected to hybrid use, for example, to support existing oil heating.
Air-to-water heat is an easy and carefree heating solution!
Your property also cools down almost for free. In the summer heat, cool air is affordably transferred indoors.
The resale value of your property increases. Ecologically and energy-efficiently heated properties are valued in the market.

An air-to-water heat or a ground source heating system?

Air-to-water heat – Ecological and economical heating solution

An air-to-water heat pump is the latest heating solution utilizing heat pump technology. Air-to-water heat pump is a heating system that takes heat energy from the outside air, just like an air source heat pump. The difference is that air-to-water heat pump transfers heat to water instead of air.

The investment in an air-to-water heat pump is usually cheaper than a ground source heating system. The cost difference between the two options depends on various factors. For instance, the amount of free energy provided by an air-to-water heat pump is typically lower than that of a ground source heating system on an annual basis. However, the difference is relatively small in the southern parts of Finland and is quickly offset by the lower purchase price of an air-to-water heat pump.

MV-Jäähdytys offers air-to-water heat pumps from various equipment manufacturers and is dedicated to assisting you in making the right hardware choice. We not only provide installation services but also offer maintenance, repair, and modernization services for the installed equipment throughout its lifespan.

Annual maintenance and fault repairs

Does your heat pump need maintenance?

Different types of heat pumps require care and maintenance in order to function as desired. We service all ground source heat pumps, air-to-water heat pumps and air source heat pumps professionally. Through us, you can get both annual maintenance and repairs up to compressor replacements.

How does air-to-water heat work?

Air-to-water heat pumps are inverter models that regulate heating power by controlling the compressor’s rpm. The compressor’s inverter improves efficiency, extends its lifespan, and reduces peak electric current consumption during start-up. RPM control ensures that the heat pump produces the right amount of thermal energy for the building.

There are a few different types of air-to-water heat pumps. In a split device, the refrigeration unit of the heat pump is divided into two parts, the outdoor and indoor unit and the refrigerant circulates between them. The refrigerant is discharged in liquid form from the indoor unit to the outdoor unit, and it returns from the outdoor unit to the indoor unit as a hot gas, which allows for the heating of water. The refrigerant can never freeze, so the advantage of split technology is its safety in conditions where long power outages can occur. As the connections to the refrigerant circuit are made on-site, the installer must have refrigerant permits from TUKES.

In Monoblock devices, all the technology is in the outdoor unit, which heats the water and sends it back warm to the indoor unit. Only water circulates between the accumulators inside the device and the outdoor unit. The Monoblock device can be connected directly to an existing heating system, such as an oil boiler, and can achieve high efficiency and significant savings in heating costs.

How is air-to-water heat collected?

The principle of operation of an air-to-water heat pump is simple. The fan of the outdoor unit circulates outside air through its evaporator, and the heat from the outside air causes the refrigerant in the evaporator to turn into gas. The refrigerant that has turned into gas is compressed to a higher pressure in the compressor of the air-to-water heat pump, and the gas becomes even hotter. With the help of hot gas, the water in the heat distribution system of the house is heated, as well as domestic hot water supply. Thus, an air-to-water heat pump is suitable as the main heating system of a house, unlike an air source heat pump.

Usually, there is enough heat in the open air for the air-to-water heat pump to operate effectively, even in cold weather conditions. However, when the temperature drops significantly, the air-to-water heat pump may need additional heating, which typically uses electricity. The specific temperature at which additional heating is required depends on the individual characteristics of the installed water-to-air heat pump.

An air-to-water heat pump requires a water-based heat distribution system. If you want to install an air-to-water heat pump in a house with direct electric heating, and you do not want to install water-based underfloor heating or water-based radiators in the house, the heat distribution can be handled with the help of fan convectors.

Financial savings

The air-to-water heat pump has become a very popular heating solution in recent years. The reason is the significant savings in heating costs compared to traditional forms of heating. Depending on the house, an air-to-water heat pump can achieve savings of about 40–70% in heating costs.
