Thermal Hot Water Storage



Please visit the official Thermocube website here (opens in new tab)


How Does It Work

As an alternative to standard pressurized hot water vessels SIRAC can offer a low-pressure thermal storage system incorporating a manifolded high-pressure 316L stainless steel heat exchanger set.

The vessel is manufactured out of a reinforced 60mm polyurethane panels. These panels are shipped as a flat pack set and are assembled onsite. This reduces shipping charges and allows the tanks to be assembled in ‘hard to get to’ areas. Once the tank frame has been assembled it is lined with an EPDM liner. This tank liner is specifically designed for high temperature and long lifespan applications.

Thermocube Hot Water Storage systems offer a fresh approach to centralised hot water storage providing heated sanitised water through an indirect heat transfer process.

Water from the mains flows through the heat exchanger set and gathers up energy stored by the stationary water in the tank. The temperature of the thermal store is maintained by SIRAC...

Hot Water Heat Pump

How Does It Work

A heat pump is a highly efficient, cost effective method of heating water. It utilizes the sun’s free energy by extracting heat from the sun-warmed air and transferring it efficiently to the water. Because the heat pump moves the free heat from the outside air to the water, rather than create heat, as a fossil fuel or electric resistance heater does, it can heat your geyser water for up to 70% less cost than other less efficient methods. As the ambient temperatures changes, the heating output of a heat pump will vary. However, even when temperatures are cooler the heat pump continues to transfer heat between air and water. SIRAC heat pumps are designed to operate between -5°c and 40°c ambient temperature.

SIRAC Commercial Hot Water Heat Pumps are specifically designed to work efficiently in South African climatic conditions. With attention to detail and innovative technology SIRAC is a commercial leader in the Hot Water Heat Pump industry

The SIRAC commercial unit is a direct result of our vast experience, observations and field testing that has taken place...
