How to choose the right heat pump
Are you considering heating your home with a heat pump? These modern heat sources have almost zero emissions and are increasingly popular thanks to their environmental benefits, long service life and energy savings. Financial support from the government through the Zelená domácnostiam programme may be another reason to choose a heat pump.
Is a heat pump right for my home?
A heat pump is a suitable choice for a modern new build. Its high heating efficiency (A+++) and energy savings also make it suitable for a renovated home. Electricity, which the heat pump needs, is available to every building. The unit provides year-round operation, heating and cooling with stable output at very low outdoor temperatures, and domestic hot water in an external tank at temperatures of up to 55 °C.
Which type of heat pump is right for me?
Heat pump types differ in how they collect heat from the surrounding environment. They are divided into:
What is an air-to-water heat pump made of?
A heat pump is a relatively simple device that works on a principle similar to a household refrigerator. It consists of a refrigerant circuit with two heat exchangers — a condenser and an evaporator —, a compressor and an expansion valve. It transfers energy from a renewable source in the outdoor environment, such as water, air or the ground, into the building.
Air-to-water heat pump
It takes energy from the surrounding air and transfers it to a water-based heating system. The working medium is heating or cooling water. Depending on their design, these heat pumps are split or monobloc units. A key advantage of air is that it is available everywhere.
Ground-to-water heat pump
This system collects heat from the ground or a geothermal borehole.
Water-to-water heat pump
This system collects heat from two wells. All three types of heat pump work best with a low-temperature hydronic system, such as underfloor, wall or ceiling heating and cooling.
Air-to-air heat pump
This type is suitable for warm-air heating systems, which use air as the working medium. Ductwork distributes the air throughout the building. In these systems, the heat pump can also provide cooling as an air conditioner. Ground-to-water and water-to-water systems may be limited by the available space or water source. An air-to-water heat pump is therefore often the most economical option in terms of purchase, installation and servicing.
Heat loss in the home
When choosing a heat pump, it is important to know the heat loss of your home. Before buying, make sure the unit is neither oversized nor undersized. An oversized unit may wear out its components faster because of frequent starts when heat is no longer needed. An undersized unit may not provide enough heat. The ATTACK Inverter R32 heat pump range includes models with outputs of 6, 9, 12, 15 and 19 kW.
Heat pumps offer several benefits: low running costs, simple controls, year-round operation, the option of receiving a grant through the Zelená domácnostiam programme, and suitability for almost every type of family home.
Key parameters
COP and EER
When choosing a heat pump, look at its COP and EER values, which indicate efficiency. COP is used for heating and EER for cooling. The ATTACK Inverter R32 air-to-water heat pump achieves a COP/EER of up to 4.6. This means that 1 kW of electricity can provide up to 4.6 kW of heat or cooling.
SCOP and SEER
These parameters are similar to COP and EER, but show average performance over an entire season. SCOP indicates average seasonal heating efficiency under standard conditions. It is calculated as the ratio of heat delivered to electricity used over the year. SCOP gives a better picture of a heat pump's actual seasonal efficiency and includes the energy use of all its components, not just the compressor. The SCOP of the air-to-water ATTACK Inverter R32 range is between 4.71 and 4.99. A higher value is better. ATTACK monobloc heat pumps provide year-round heating and cooling with stable output, even at very low outdoor temperatures. SEER is determined in a similar way to SCOP and indicates cooling efficiency. It is measured under changing ambient conditions in real operating mode. Here too, a higher value is better.
Make the most of a heat pump
A simple, energy-efficient solution for a home or business, the option of applying for a government grant, high comfort, two to five units of electrical energy produced per unit consumed, reliable operation and a long service life.
