Kaisai heat pump

Heat pumps are a convenient and cost-effective way to heat new and modernized buildings. These devices are characterized by an ecological character, which is why their popularity among investors and installers is constantly growing. The use of heat pumps is associated with numerous benefits, and their manufacturers are providing the market with increasingly interesting facilities to meet the needs of even the most demanding users. One of the leading brands in this industry is Kaisai. Discover its heat pumps from the Arctic series!

In this article you will learn:

  • how heat pumps work,
  • what are the advantages of heat pumps,
  • what makes Arctic heat pumps stand out?

How does a heat pump work?

A heat pump is a device that takes free energy from the air or ground and uses it with a small amount of electricity to heat a building and prepare domestic hot water (DHW). It does not emit any harmful substances into the environment, which makes it a very ecological solution. The heat it generates comes from about 80% renewable energy sources (RES), and only about 20% from electricity. Thanks to this, everyone can save a lot on heating.

Pumps use natural resources such as:

  • geothermal heat,
  • heat of ground and surface water,
  • heat of air.

It is worth noting that these sources do not have to have a temperature at the level that you want to achieve in the rooms. Pumps have the ability to convert cold into heat (and vice versa) using a small amount of electrical energy. The devices have two sources:

  • upper – water tank (central heating system), where the energy consumed by the pump is supplied,
  • lower – ground or air (the higher their temperature, the less electricity the pump consumes).

Kaisai heat pump The choice between a ground and air heat pump should be dictated primarily by financial possibilities. The first solution requires greater financial outlays due to the need to make a lower source (drilling). A cheaper investment alternative - due to easier installation - is precisely the air-to-water heat pump .

Efficient air pumps can be found in the Kaisai brand offer. It supplies the market with numerous solutions in the field of renewable energy, which also include heat recovery units and photovoltaic systems. By using the full potential of these products, every household can ensure energy independence from external suppliers. Let's take a closer look at the key advantages of Kaisai heat pumps from the Arctic series.

Heat Pump - Advantages

The advantages of heat pumps are numerous. Both financial and ecological arguments speak in favor of using these devices:

  • Reduction of CO2 emissions – up to 80% of energy is obtained from the air, eliminating any exhaust fumes and reducing electricity consumption by up to 20%. In the case of an additional photovoltaic installation, the use of a heat pump can become completely free.
  • User comfort – heat pumps are fully maintenance-free devices. They automatically maintain the set temperature in the building and domestic hot water, regardless of external conditions. They also do not require fuel replenishment or regular maintenance in the form of ash removal.
  • Safety – unlike traditional heating systems, a heat pump does not pose a fire hazard and does not carry the risk of a gas explosion. By choosing this solution, you can also do without carbon monoxide sensors.
  • Savings – this is one of the most important advantages of heat pumps. These devices contribute to a significant reduction in the operating costs of a building. The costs of heating and preparing hot water are reduced by up to four times. In the case of pumps, such expenses as chimney inspections are also avoided.
  • Possibility of cooling rooms – it is worth remembering that heat pumps can be used not only to heat rooms in winter, but also to cool them in summer.

Arctic heat pumps

The Kaisai brand offers two types of heat pumps from the Arctic series:

  • air-to-water heat pumps in monoblock version
  • and air-water pumps in split version.

The first type are single devices with heating power from 6 to 30 kW. They can be used for heating and cooling, as well as for heating domestic hot water. They are used in single- and multi-family houses and in public utility buildings. Importantly, they can be used in mixed heating systems, i.e. radiators and underfloor heating. Because they are standardly equipped with a mixing group control, which controls the supply temperature of various heat receivers in the central heating installation

The undoubted advantage of this solution is its compact nature. The device is characterized by easy assembly and does not take up much space in the room. It is a complete, hermetic, ready-to-use equipment that does not require any specialist inspections. In the case of monoblock pumps, it is only necessary to protect their heating medium (i.e. water) from freezing as a result of loss of power.

Split heat pumps consist of two devices. The installation of the internal and external units must be performed by a qualified installer with permissions to work with refrigerant gases. The advantage of this solution is the lack of risk of freezing of the heating medium and easier access to hydraulic elements.

The split heat pump can operate in a very wide range of outside temperatures, and its standard equipment includes, among others, support for two heating circuits, an auxiliary heater, a circulation pump, a safety group and a heated drip tray. The Kaisai brand offers split models with heating power from 6 to 16 kW.

Both types of heat pumps from the Arctic series can be controlled via a mobile application, which allows you to set the flow and domestic hot water temperature, switch zones and control electricity consumption.

Heat pump – why is it worth it?

A heat pump is a solution that is worth using when designing heating systems in new buildings. On the one hand, we do not pollute the natural environment, and on the other hand, we significantly reduce bills. If your client also invests in a photovoltaic installation, they will be able to enjoy the benefits of completely free heating.

Ecological and economic aspects are of course the most important benefits associated with the use of a heat pump, but not the only ones! Familiarize yourself with the Kaisai brand assortment , and you will quickly see how comprehensive and convenient the Arctic series devices are.
