TWH Exhaust Air Hot Water Heat Pump:

High efficiency exhaust air source heat pump packaged with integrated domestic hot water tank & heat pump components! The TWH exhaust air heat pump is available up to 270 litre storage capacity and with efficiency outputs up to a COP of 3.7 when producing hot water.

A range of internal domestic hot water tanks can be selected for the required storage in your project. Very small installation area as the heat pump sits on top of the cylinder, 65°C hot water temperature and an excellent COP are factors in favour of the TWH.

The TWH exhaust air heat pump can be used with solar thermal systems, electric P.V., gas/oil boilers and heat input from wood fuel buffer systems.

In most dwellings the TWH exhaust air heat pump can use the ventilation air from the building to achieve the hot water requirement of the occupants in an efficient and cost effective manner.

Each TWH exhaust air heat pump installation package includes:

Extremely small foot print, backup / boost electric heater & controller

Main Benefits:

  • One of the most compact hot water heat pumps on the market
  • Up to 65C flow temperature - a true hot water heat pump.
  • One of the quietest units on the market @ 39dBA.
  • Maximum flexibility solution for domestic hot water
  • Made in Europe for reliability & peace of mind.
  • Extensive installation options for each unit.

ETWH thermodynamic water storage heaters stand on the floor and run on ambient air down to +5°C. They are used for heating domestic hot water up to 65°C and are therefore perfectly suited for replacing electric water 
heaters. The two models come with a 1.5-kW back-up immersion heater.

They comprise principally:

  • A glass-lined tank with magnesium anode protection;
  • A rotary compressor;
  • A copper condenser located around the tank;
  • And a specific controller for a DHW application that incorporates programming, various operating modes, back-up management, the anti-legionella function and the frost protection mode;

Use Conditions:

  • Max operating temperature of the tank: 70°C
  • Max operating pressure of the tank: 8 bar
  • Air temperature for thermodynamic module functioning: +5 to +43°C
  • The room in which KALIKO ESSENTIEL is installed must be frost-free.
