Invest in the future of your home with our highly efficient heat pumps. By using the latest technology, our systems enable you to significantly reduce your heating costs.

Compared to conventional heating systems that use fossil fuels, our heat pumps offer high energy efficiency, which is directly reflected in your monthly operating costs. An air source heat pump generates a total of four parts of heat for the house from one kilowatt hour of electricity using the ambient air. In the long term, this means considerable cost savings, which means that the initial investment is quickly amortized.

By switching to a heat pump, you not only secure financial benefits and make a contribution to environmental protection, but also increase the value of your property. It is an investment that pays off for you in many ways.

Regardless of whether you live in a newly built house or an existing building, an alpha innotec heat pump offers a cost-effective and environmentally friendly heating solution for any type of building. However, certain conditions must be observed for effective retrofitting in existing buildings.

THERMAL INSULATION IS CRUCIAL

The quality of the building's thermal insulation plays a decisive role here, enabling the heat pump to heat energy-efficiently and with minimal power consumption. Because if the building does not lose much temperature to the outside, a low water temperature in the heating system is sufficient to keep the building warm even on very cold days.

Low-temperature heating systems such as underfloor heating support the efficiency of a heat pump, as they generally require lower flow temperatures than conventional radiators. This means that the heat pump has to generate less heat and also requires less electricity.

However, a heat pump can also be an efficient heating system in conjunction with radiators. In this case, a specialist should determine exactly which heat pump is suitable for retrofitting.

Our powerful air/water heat pumps with the environmentally friendly refrigerant R290 are an excellent choice for retrofitting a heat pump, as they have sufficient power to efficiently heat conventional radiators with flow temperatures of up to 78 degrees. High-temperature heat pumps could even heat completely unrenovated old buildings from past centuries, but would require a lot of electricity to do so, resulting in high heating costs.

For long-term comfort, efficient heating and low electricity costs, the thermal insulation of a building should be designed so that the heat pump can heat with a maximum flow temperature of around 50-55°C.

THE HEAT PUMP INSTALLATION SITUATION

It is also important that there is sufficient space both in the house - ideally in the basement or a special boiler room - and on the property to install the heat pump. When installing a monobloc heat pump outdoors or a split heat pump, an appropriate distance from the property next door should also be maintained in order to avoid disturbing noise.

Retrofitting a heat pump can also be a smart decision if your home is already equipped with a modern condensing boiler. In a hybrid heating system, the heat pump works together with the condensing boiler, which is only switched on when the heating requirement exceeds the capacity of the heat pump. This leads to a reduction in the consumption of gas or heating oil and therefore to lower heating costs. The combination with an existing solar system and the retrofitting of a buffer storage tank can also prove to be economically advantageous.

You can retrofit all types of heat pumps. The advantages and disadvantages of the respective system for you in terms of installation, the existing installation situation, the investment costs and, of course, the scope of the conversion measures are decisive when making your choice. Only you can make this decision for yourself and your home. You should seek advice from your installer and, if you are interested, from an experienced alpha innotec expert.

GROUNDSOURCE HEAT PUMP (BRINE-WATER HEAT PUMP)

Ground source heat pumps use the constant heat in the ground, making them a particularly efficient and reliable heating solution. The heat is extracted from the ground via geothermal probes or ground collectors, which is particularly quiet and effective.

Retrofitting a geothermal heat pump requires earthworks or deep drilling, which can be difficult in densely built-up areas. The large amount of space required for ground collectors must also be taken into account. The costs for retrofitting a ground source heat pump are generally higher than for an air source heat pump simply due to the ground work required.

AIR HEAT PUMP (AIR/WATER HEAT PUMP)

Air source heat pumps use the heat from the ambient air, even at temperatures colder than -20 °C. They are ideal for retrofitting as they can be installed and connected almost anywhere and easily. Installation is straightforward, especially with modern monobloc appliances.

The fluctuating outside temperatures during the calendar year pose no problems for a professionally designed heat pump. If the air heat pump reaches its limits on isolated extremely cold days, a permanently installed heating element provides the necessary support. Another attractive option for retrofitting a heat pump is hybrid operation of a heat pump in conjunction with a fossil fuel heating system for peak loads.

Due to the noise generated by the installed fan, an outdoor installation is advisable, whereby the distance to the neighboring property must be maintained. Air source heat pumps offer a flexible and cost-efficient heating solution. Practical experience shows that in most cases an air source heat pump is chosen for retrofitting.
