Air to Water Heat Pumps

Air to Water Heat Pumps

This works on the same principles as the air to air heat pump, distributing heat via your wet central heating system or an under-floor heating system.

               

There is a choice of heating systems for your home:

 

1 - the under-floor heating/cooling system

Most often installed in new properties, it is embedded in screed and is therefore invisible.

 

 

An under-floor heating system installed throughout your home pumps a controlled flow of warm water in winter, and cooled water in summer through plastic tubing embedded in the floor.

 

 

This system gives you optimal comfort: 

  • Deliciously pleasant Heating: hot water (30°-35° max) is pumped through the pipes, providing sufficient warmth even on a cold day.

  • Refreshingly Cooling: cold water is pumped through the pipes cooling the home by several degrees.

 

The advantages of an under-floor heating system

 

Comfort :

 

  • An even temperature throughout your home
  • Real Warmth
  • Noiseless
  • Delightfully refreshing on hot days

 

Economical :

 

  • The same comfort at 18° as at 20° with a standard radiator
  • An average economy of 14% compared to a standard radiator because the water in the pipes is at low temperature (35°)

 

Invisible :

  • No more ugly, cumbersome radiators
  • No more blackened walls and ceilings
  • All your walls are free

2 - Fan coil units

 

Fan coil units exist in various forms and can be adapted to any inside living space, mounted either on the wall or at floor level, set into the ceiling or installed in the attic with ducts.

The hot and cold water produced by the heat pump is pumped through a low-temperature radiator coupled with a ventilator.

 

Because it guarantees that the heat or the cool air is spread more evenly throughout the home, this low-temperature radiator is advantageous compared with a standard radiator, and as the latter often operates at a maximum temperature of 45°, with the former you save energy.


3 - 
Radiators

As with fan coil units, hot water produced by the heat pump is pumped through a network of pipes to the radiators. This system cannot cool the home.

With an existing installation, we must make sure that the dimensions of the radiators suit the temperature of the water that the heat pump is able to provide.

Either the radiators work with water called “low-temperature” (45°-60°), or they run at a higher temperature of up to 80°, and are called “high-temperature”.

 

 

Some heat pumps can provide these high temperatures: DAIKIN Altherma high temperature and HITACHI Yutaki S80.
