Solartherm Hot Water Cylinder
As with all Duratherm ® products, the boilers with PEX polymer (Cross-linked polyethylene) offer unsurpassed corrosion protection and also eliminates the need for costly sacrificial anode replacements. All fitting and electrics are standard thus simplifying any possible future repairs. 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.
In a direct solar system, the water is heated by circulating water from the storage vessel through the solar panels. This can be done naturallyvia thermo-syphon or through a pump. The system is simple and cost effective however it must be noted that the pressure in the storage cylinder will be transferred to the panel which makes this unsuitable for some solar panels. This system is also not suited for areas where frostand very low temperatures occur because of the possibility of the fluid inthe panels and pipes freezing. It must be noted that there are controls available that reverse warm water through the panel to prevent freezing, however this could be costly.
