Heat Pump in Bratislava and the Surrounding Area

Both work on a similar principle – they transfer heat between the outdoor and indoor environment. An air conditioner (air-to-air system) heats or cools the air in the room directly. An air-to-water heat pump heats water for the heating system (underfloor heating, radiators) and hot water for the bathroom and kitchen. Read more on our blog.

Some heat pumps can. It depends on the type of unit and the heating system – cooling is possible, for example, through underfloor systems or fan coil units designed for it. With standard radiators, cooling is generally not used.

It depends on the house. The key factors are insulation, the type of heating system, hot water consumption and what you currently heat with. We do not quote general savings percentages – we assess the benefits for your specific house.

Often yes, but it requires the right design. For radiators that need a higher water temperature, high-temperature heat pump variants are used. The insulation of the house also matters. We will assess whether it is a suitable solution in your case.

The output is determined by the heat loss of the house, not by its floor area. A project or energy performance certificate, information about insulation, the type of heating and hot water consumption all help. Read more in the article What heat pump output do I need.

Households can use the Zelená domácnostiam programme, managed by SIEA. The conditions, the amount of the contribution and the dates change – you will find current information at zelenadomacnostiam.sk. Read more in the article Heat pump subsidy.

Noise comes mainly from the outdoor unit and depends on the model, the current output and the location. Do not place the unit under bedroom windows or in narrow spaces where the sound reflects. Read more in the article Heat pump noise.

Note down the error code, check the circuit breaker and whether the outdoor unit is blocked by snow or objects. Do not interfere with the refrigerant circuit, and contact a service technician. Read more in the article Heat pump service.

Yes, an air-to-water heat pump heats even in frost. However, its output and efficiency fall as the temperature drops, so the design has to allow for this. The manufacturer states the operating temperature range for each model. Read more in the article Does a heat pump work in frost?

Not always. It depends on the water temperature the house needs. It is often enough to replace a few of the smallest radiators or choose a high-temperature unit. Only an assessment of the house gives the answer. Read more in the article Replacing a gas boiler with a heat pump.

The registration and application are primarily made by the household, and by the installer only with an officially certified power of attorney. We prepare the design, check that the equipment is on the list of eligible equipment and supply the invoice and documents needed for the application. Conditions change, so see the current status on the Subsidies page.

There is no single figure that applies to every house. It depends on the price of the equipment, the subsidy, your current heating, heat loss and energy prices. When replacing a gas boiler, the payback can be long. We explain how to calculate it in the article Heat pump payback.
