Heating Services – Heat Pumps

Why Heat Pumps?

Heating geyser water is typically the largest cost of energy in home today. An average South African family will spend R5000 (as at December 2013) or more to heat water every year! The Geyser Heat pump is a heat pump that is designed specifically to heat your geyser water using hardly any energy. The Geyser Heat pump is connected to any existing electric, gas, oil, or propane water geyser in any home or business.

It makes use of a renewable energy source – the ambient air temperature in a garage, roof, basement or utility room is drawn in through the condenser to heat the water. The Geyser Heat pump is up to 370% efficient as compared to 60-95% for traditional water heating systems.

This means that for every 1 unit of energy required to operate The Geyser Heat pump, 3.7 units of energy are generated from the ambient air to heat the water. In laymen’s terms this means for every R1,00 you spend on electricity you get R3,70 worth by using renewable energy source.

 

Refrigeration Service

In certain cases up to 3 geysers can be heated with one heat pump. While Kwikot geysers are recommended, most geyser types can be used. Oil, gas, or propane usage is significantly reduced which means lower running costs, fewer emissions, smaller carbon footprint, and a safer and healthier environment for all.

Features:

  • Highly efficient (up to 370%)
  • Fail safe design ensures hot water at all times
  • Various models suitable for any size geyser
  • Engineered for safe and easy installation
  • Virtually maintenance free
  • Dehumidifies and cools surrounding air
