Water heating systems are based on the principle of heat pump technology, which reclaims heat from the environment and transfers it via water heat exchangers, for use when it is required. Unlike solar heating, heat-pump water heating systems supply constant on demand water up to 60°C. They do not require hot sunny ambient temperature conditions to operate effectively.

Electric geysers have a COP (co-efficiency of performance) of 1:1, for example, for every 1 kilowatt of energy used, 1 kilowatt of energy is produced whereas the output generated by a heat pump can exceed four and a half times the input, ie a COP of 4.5

Two additional and unique advantages of an water heating system is that it costs 75% less to operate than an electric geyser, and some models offer air conditioning as well as water heating. The range includes models to suite all applications from domestic to commercial to industrial. Wherever hot water is required, we can provide it efficiently and economically.

Small Capacity Water Heater
This quiet, compact, self-contained unit is ideal for indoor installation in residential and light commercial applications.

Medium range commercial water heater
This weather proof, self contained cabinet is ideal for outdoor installation in small and medium commercial applications.
