Altherma logoEfficient and environmentally friendly

Kereen is an approved dealer partner for the highly efficient and environmentally friendly Daikin Altherma heat pumps. We are able to design and install a heating system for any domestic or commercial project that will give you optimal comfort and guaranteed savings on your fuel bills.

 

Air to Water Heat Pump

Air-to-water heat pumps simply extracts the ambient heat in the outdoor air.

heat-pump-working

  1. Air passes the heat exchanger and refrigerant absorbs heat from outside air
  2. The vapour passes into compressor and compression increases the temperature
  3. Hot vapour is condensed in 2nd heat exchanger, rejected heat is passed onto heating/hot water system
  4. The liquid refrigerant passes back through expansion valve ready to start cycle again

Saving money & the environment

70% of your heating free from the air

Daikin Altherma is a domestic heating and hot water system based on air-water heat pump technology, which generates up to 70% of the heat free from the air and represents a highly energy-efficient alternative to oil, LPG and electric storage systems.

Up to 5 times more efficient

As a result, Daikin heat pumps can offer efficiencies up to 5 times higher than a fossil fuel boiler, so they will typically save on running costs compared with old oil and LPG boilers.

New build projects

Daikin Altherma MonoblocDaikin-monobloc

Daikin Altherma low temperature monobloc heat pump is an efficient and space saving option because it consists of a single outdoor unit, with no indoor unit required.

All you need inside is a domestic hot water cylinder. Yet it provides a complete heating, cooling and domestic hot water solution, delivering excellent energy efficiency.

 

Daikin Altherma Split SystemDaikin-low-temp-split

The Daikin Altherma low temperature split heat pump system is an efficient heat pump option and consists of an outdoor unit and an indoor unit.

Daikin Altherma Low Temperature Split heat pump reduces running costs, by achieving the very best seasonal efficiencies available at every outdoor temperature

even when the outside temperature is down to as low as minus 25°C.

 

 

Retrofit projects

Daikin Altherma High Temperature Heat Pump SystemDaikin-HT

In older or harder to heat properties, you need a system that reliably delivers higher water flow temperatures of up to 80ºC, without necessarily replacing the whole radiator system.

Daikin Altherma high temperature heat pump system offers heating and domestic hot water for your home. This system can perfectly replace a traditional boiler and connect to the existing piping. The Daikin Altherma high temperature system is therefore the ideal solution for renovations.

 

The split heat pump system consists of an outdoor unit and an indoor unit and can be completed with solar connection.
