3 Technical description

3.1 General

The heat pump is a device intended for efficient heating of DHW in residential or small business
spaces. In heating the DHW, the device simultaneously cools the room where the air is
returned to and heat for heating water has been taken from. The device heats the DHW as
well as cools the room. Here we have to stress that it will only cool the room when there will
be a simultaneous need for heating DHW.

NOTE

For maximal efficiency and economical use, we advise to use air from rooms where
waste heat is generated for heating DHW (boiler rooms, laundries, kitchens,
basements, pantries ...)
