Heat Pumps can reduce your water heating bill by up to 75%

Water Heater
  • As the electricity price increases, the need to reduce electrical consumption is becoming more and more critical. Water heaters can be used in a wide range of applications from domestic to industrial instillations. Outputs range from 2.8kW to 77kW and larger capacities can be achieved by coupling mutiple units together. Elecrtical Heater: 1kw in = 1kW out, with heat pump technology 1kw in = up to 3.5kw out!
Energy Saving to Hotel Schools and Hospitals
  • Huge Electrical Savings.
  • Heats regardless of weather, not dependant on sunlight as with solar.
  • Built in timer and remote control.
  • Heat water up to 60 °C.
  • Operated in ambient temperatures from 10 °C - 43 °C.
  • Simple new installations and retro fits.
  • Nationwide backups.
Boiler vs Water Heater
  • The above graph is taken from an actual test study where water heaters replaced boilers in a prominent South African boarding School. In the first recorded test period, the boiler used 1742kW of electricity. At a cost of 72 cents per kW, the boiler cost the School R1253.24 for five days use. In the second recorded test period, a water heater had been installed to replace the boiler. The water heater used 655kW of electricity at a cost of R471.60 for the five days meaning a saving of R781.64 per five day week. A saving of 62.4% was realized.

Working Principle

  • A standard 3kW geyser (150 litre) running for a 24 hour period would cost approx. R64.80. The heat pump equivalent (150) running for a 24 hour period would cost approx R21.60 with a saving of R43.20 per 24 hour cycle
