There are countless questions that arise before choosing the most suitable heat pump for your home. Specialists can answer them, but would you like to know more before consulting? Below are the most frequently asked questions and their answers.
Which heat pump is best?
There is no single answer. The brands we represent are characterized by high-quality equipment and technical data. The best one can be selected individually for each client. In order to make the right choice, it is important to find out the parameters of the heat pump, the coefficient of performance (COP) and other technical details. The most important thing is that the model meets the “requirements” of your home.
What power heat pump do I need for my home?
The power of the heat pump is selected based on the area of the house and the efficiency class (thermal resistance) of the house. For example: an 8 kW heat pump would be suitable for a 150 sq. m. Class A house.
What is the difference between a heat pump with and without an integrated tank?
There are two types of heat pumps on the heat pump market: with and without an integrated tank. If you purchase a model with an integrated tank, you no longer need to buy a water heater separately. Models without an integrated tank consist of an outdoor and indoor unit. The water heating tank can be purchased separately and connected to the heat pump.
When is it worth choosing an integrated tank?
A model with an integrated tank is more often chosen when the house is newly built, there is not much space in the boiler room or just in the house, because the device can be placed practically anywhere. Such models also stand out for their design and even more convenient operation.
Can a heat pump be connected to an old system?
Of course, yes. Air-to-water heat pumps are just as easy to connect to an old system as they are to install in a home that does not have a heat source.
What is the warranty period?
All air-to-water heat pumps come with a 24-month warranty. There is an option to extend the warranty by ordering annual maintenance from the supplier.
How long does it take to install a heat pump?
Air-to-water heat pumps are installed within 1-3 days, depending on the order or complexity .
What needs to be prepared in the boiler room before the technicians arrive?
— Heating manifold cabinet, or pipeline to which the heat pump will be connected (thermofikato); — Drinking water pipeline, cold and hot; — Electrical input 1F or 3F (depending on the heat pump), cable 2.5 square x3, circuit breaker 25 A, brought to the place where the indoor unit will be installed; — Sewerage pipeline – required for draining the system, optional
Do I need to look elsewhere for installers when ordering a heat pump?

“The outdoor unit of my heat pump is freezing. Is this normal?”
Every year, as soon as the heating season begins, questions about heat pumps pour out like from a cornucopia. How much does heating with a heat pump cost? The questions often overlap, so we provide answers to the 5 most frequently asked questions. Yes, the freezing/defrosting process is completely normal. It would be worth worrying if the outdoor unit does not freeze. Heat pumps constantly freeze and then perform a defrosting function – melting the accumulated frost and ice. What is pump defrosting? When heat pumps operate in heating mode, the outdoor air is relatively cool, and the outdoor unit then acts as an evaporator. Under certain temperature and relative humidity conditions, frost forms on the surface of the outdoor unit. A layer of snow/frost will interfere with the operation of the heat pump, which will make the pump work harder (and therefore less efficiently). Frost must be removed. The heat pump has a cycle called defrost cycle which removes frost/snow from the outdoor unit. The heat pump defrosts regularly when frost forms. The defrost cycle should last for a period of time to melt the ice while maintaining efficiency. During the defrost cycle the heat pump automatically runs in reverse for a certain period of time. This action temporarily warms up the outdoor unit (melts the frost from the outdoor unit).
“Even though it’s not very cold outside, it freezes very often. Why is this happening and is it normal?”
Questions about heat pumps are all relevant, like this one: When the outside temperature approaches 0 and the humidity rises, defrosting occurs frequently. Remember this rule: More humidity -> ice forms faster -> defrosting is required more often!
“Which is better: a heat pump with an integrated tank or a freestanding water heater?”
Depending on your wishes and needs. If you don’t have much space, it’s better to go with an integrated tank, since the internal unit only takes up 1 m2. If you want innovation, a beautiful, special design, integrated WiFi, etc. – an integrated tank. Another advantage of an integrated tank is stainless steel heaters. High-end devices are usually equipped with a stainless steel tank, which makes the set a little more expensive, but the tanks are more durable. Of course, you can complete the model with a separately installed stainless steel water heater, but then the price becomes similar and you lose space and aesthetics in the boiler room. If these things are not important or relevant to you and you want to save money (since the price difference between models with an integrated and separate tank is ~ € 1000) – choose a separately installed water heater. In the event of a breakdown, you don’t have to worry about either a separately installed water heater or an integrated tank. By choosing a reliable manufacturer and contractor, you will definitely get the necessary parts and service.
“How much does heating with a heat pump cost?”
It all depends on the area of your house, resistance, and the heat pump you choose. Also, whether you have radiators or underfloor heating.
