Air-Source Heat Pumps

Giving you heating and hot water throughout the year, air source heat pumps generate heat energy from the surrounding air. They continue to work even when temperatures outside dip as low as -15°C.

Made in Germany

This series of air-water heat pumps meets the winter and summer comfort requirements in residential installations, as well as small-mid sized commercial ones.

Heat pumps.

A heat pump is a device that draws heat energy from the building's surroundings (air, ground or water) and transfers it to the central heating installation. In this way, it obtains clean, ecological energy at low costs (electricity used to power the compressor). It is used for heating the building, utility water, and also for cooling rooms in hot weather. While looking for a comfrotable and cheap solution for heating of your home we often think about using a heat pump. First of all, we want the heat pump to provide lower costs of our heating and we want it to be relaialble to us for several decades. This is fully justified because the prices of traditional fuels are changing rapidly. They are getting higher every year and it is difficult to predict what the situation will be in the next few years. Two-thirds of the cost of maintaining a building are related to the heating. By using an inexpensive heat source, such as heat pumps, we can ensure low heating costs for up to 50 years. Currenlty heat pumps are a reliable, economical and environmentally friendly source of heat with a guaranteed future. In Switzerland, every third house is already equipped with a heat pump.

How does a heat pump work?

 

Heat pumps work by taking natural warmth out of the surrounding environment to provide hot water and heating to your home. There are three main types of heat pump: ground source, air source, and water source. The name of each one describes where the appliance takes its heat from, and, therefore, each one works in a slightly different way.

1. Absorption

Before anything else can happen, the heat must first be collected. Depending on the type of heat pump, the heat will be absorbed by a refrigerant either from the ground, air or water source. This takes place in the evaporator with the refrigerant changing from liquid to gas in the process.

2. Compression

The refrigerant is now a gas instead of a liquid and the gas is compressed to increase its temperature even more. It is this heat that can be used to warm up your radiators or underfloor heating.

3. Condenser

As the refrigerant transfers the heat that is to be used in your home’s heating system, it gradually cools down and condenses back into a liquid. This occurs in a second heat exchanger. One of the reasons why heat pumps are so efficient is because cooler water from the central heating can continue to absorb the heat from the liquid refrigerant within this second exchanger.

4. Repeat

Once the refrigerant has cooled right down, it passes through an expansion valve. In here, the liquid’s pressure is decreased and it returns to the evaporator to begin the whole cycle again.

Underfloor heating is known for providing great comfort while consuming less energy than normal radiators. It's worth placing these water pipes or electric heating cables under the floor! Find out about some of the most important benefits of installing underfloor heating in the description below. Underfloor heating is becoming more and more popular, especially with those building their own new homes. The incentive is comfort, no visible heating elements, vertical temperature distribution in rooms and emphasized by many, lower heating costs than when using conventional heaters.

 

TESTIMONIALS

Wall Heating - We usually look for heating solutions that will be both cheap to operate and environmentally friendly, nowadays that focus is on surface systems. Before we decide on heating our home it is worth getting to know the disadvantages and disadvantages of every system and decide which option best suits you.

 

About EHS

Renewable energy can be obtained from sources like: water, wind, solar, land or renewable raw materials. Unlike fossil fuels, most of these sources are endless and they cost nothing. Fossil fuels such as coal, oil and gas come from leftover plants and animal debris that has been decaying for millions of years. These resources are therefore limited and their prices will continue to rise. It's now time to start using renewable energy. It will overtake and it will exclude fossil fuels completly in the next few years.
