Why should you install a Heat Pump Water Heater?
Heat Pump Water Heaters are the most cost effective water heating system available on the market compared to other technologies such as solar, gas and electric cyclinders. The system extracts heat from the air temperature, and uses only one third of the energy of a conventional water heating cyclinder.
Why should I choose a Stiebel Eltron Heat Pump Water Heater?
- Stiebel Eltron's 30 years of research on heat pumps in Germany has ensured that the Stiebel Eltron Heat Pump Water Heater has the highest efficiency rating is its class.
- The actual level of stratified water is best in its class.
- The actual delivery of hot water is market leading - 80% heated to 60 °C.
- It has an outer roll bond condenser for heating the water which provides the highest efficiency, without direct water contact.
- It has active defrost, meaning it uses the hot gas to defrost any ice build up on the evaporator. Ths allows the unit to operate in Low air temperatures.
- It has a lower amperage compared to other models - no electrical upgades required.
