EcoHot - the Hot Water Generator, is an air source heat pump which functions on a basic refrigeration cycle, common to all refrigeration and air conditioning systems. The unique advantage of this system is that it also utilises ambient heat energy to generate hot water, thereby substantially saving on running costs.

In conventional heaters, 1 kW of electrical energy provides 1 kW of heat output. These systems are not energy efficient as their COP is 1. In EcoHot, when 1 kW of electrical energy is given to the compressor, the system delivers 4 kW of heat output.
