Our pre-mixed solar heat transfer solution is non-toxic and fully biodegradable with 90% degradation taking place over the first 30 days. Suntask antifreeze fluid is based on propylene glycol blended with corrosion inhibitors and ultra pure water. The formula ensures high solar temperature tolerance (170°C-200°C) and excellent freeze protection (-20°C)
The solar hot water cylinder is a very important part of the system – its job is to provide efficient storage for the free heat the solar collectors have produced.

Why Suntask solar tube collector?
Suntask use a high efficiency heat pipe and heat transfer in design to conduct the heat from within the evacuated tube up to the header. Suntask company is the world’s pioneer in solar tube innovations with strict conformity with the ISO9001 Quality System.
Suntask panel is a perfect combination of the vacuum tube and the heat pipe:
Higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorber coating and perfect combination with high vacuum heat preservation
Wide applicable range: as the heat pipe has less heat capacity, it can be started quickly even under cloudy fine day and collect heat effectively. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent lowing of heat efficiency due to frost cracking or scaling
Each individual tube can work independently, and the whole system can still work if individual tube is damaged. The service life of the heat pipe can be longer than 20 years
The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replacement of damaged glass vacuum tube.
Solar Craft Ltd design and install complete solar panel packages for thermal energy that are one of the most cost-effective sustainable energy systems and that can be easily integrated into your conventional heating system.
We guarantee complete solar kits installation to the highest European standards at the best price.
Solar Craft’s solar hot water systems are designed to meet a certain percentage of your overall hot water requirement over the year. In a typical dwelling, this is usually 60-75% of the annual hot water requirement, but this can vary depending on economics and hot water requirements. The higher your hot water usage, the more beneficial a solar hot water system will be, as more “free” solar energy will be used. When a solar water heating and hot-water central heating system are used in conjunction, solar heating will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain in place to provide for any heating that solar cannot provide.
Please contact one of the Solarcraft Technical sales staff, who would be more than pleased to discuss your solar water heating requirements and design most efficient solar heating systems to be suitable for your home.
