High Temperature Heat Pumps

What is a heat pump?

heat pump: what is it?

It all starts with the sun. The sun warms up our atmosphere and the outer layer of the earth’s crust. In one year the energy sent to the earth by the sun is 50 times higher than the total consumption of energy on our planet. This makes the sun a vast and inexhaustible source of energy.  On sunny days you can feel the thermal energy from the sun on your skin. But actually, there is always lots of thermal energy in the air, even on cold winter days or even at  night. And not only in Florida or the south of Spain, but also in countries like Sweden or Norway where thousands of houses already have heat pumps.

How do heat pumps work?

A heat pump only needs a heat source (the outside air), two heat exchangers (one to absorb and another one to release heat) and a relatively small amount of drive energy to keep the system going.  A heat pump extracts thermal energy from the environment.  In the case of Daikin Altherma the source is the outside air. The pump extracts the energy at a certain temperature, increases that temperature and then releases it into a medium which in the Daikin Altherma system is the water running to your low temperature radiators, under floor heating system or fan coil units. Between those two media the heat is moved by means of a working fluid.

Compressor – the essence of heat pumps

As the working fluid passes through the evaporator and extracts heat from the air, it turns into a gas. This is where the compressor comes in. When you compress a gas the temperature rises. (for example if you inflate the tyre of your bicycle, you can feel the air inside warming up through the rubber).  Inside your house the second heat exchange takes place when the compressed gas enters the condenser, a surface which is colder than the gas itself. Finally, the gas condenses and releases its heat – this heat then warms up your house.

Less energy, pleasant warmth in the home

Daikin Altherma heats up to 5 times more efficiently than a traditional heating system based on fossil fuels or electricity. By making use of the heat in the outside air, you use much less energy while still enjoying a stable and pleasant level of comfort.  Daikin Altherma provides energy efficient, eco-friendly heating.

Minimal installation cost

Daikin Altherma takes heat form the air. No digging or excavation works are required. Both the outdoor and indoor units are compact. The external unit can be located easily outside any building, including flats. Without flames or fumes, there is no need for a chimney or constant ventilation in the room where the Daikin Altherma’s indoor unit is installed.

Flexible configurations

Daikin Altherma can be configured for use in both new and refurbishment applications, and connects to standard low temperature radiators, underfloor heating or fan coil units. If you already have a heating system, there is no need to change it all.

Entire comfort for your family

Daikin Altherma satisfies your heating requirements but it can also supply your sanitary hot water. It comes with a cooling option for hot summer days.

Absolutely safe

Daikin Altherma works without oil, gas or other hazardous substances – reducing potential risk that goes together. Moreover, you don’t need a gas connection or a fuel tank. No risk of intoxication, smell or pollution from leaking tanks.
