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.

  • COP exceed 3.85
  • Operating range from minus 7°C to plus 43°C ambient conditions.
  • Hot water outlet adjustable between 48°C and 60°C

STH Solar - Solar Collectors

With the advantages of 3 solar collectors, as well as new resin and fibre technology, combined is a reliable module that can be used for different applications from small to big installations. Pricing on conversion systems might vary, should the distance between the existing geyser and the solar collector be bigger than 5 metres.


STH Solar - Solar Power Stations

STH also manufacture and install its own patented and unique steam driven solar power stations. We manufacture single-phase, 3-phase, off-grid or grid-tie systems. Overheating protection: max 68 degrees celcius. Custom designed to suite your requirements. Over voltage protection: 15,5v +/- 0,5v.


STH Solar - Solar Geysers

The unique PEX coating is suitable for all water types and will always resist any type of build up of impurities found in water e.g. Lime build-up whilst offering extended service life. Our boilers, with PEX polymer (Cross- linked polyethylene) offer unsurpassed corrosion protection, eliminating the need for costly sacrificial anode replacements.
