Cold war

003. Frost Damanged Solar Thermal SystemRecent arctic weather has reminded people with solar thermal heating systems that their solar panels need to be treated well and regularly maintained around the year if they are to continue to provide around 50 per cent of the hot water the home needs during the year, says Sentinel.

 Solar thermal heating systems can experience a wide range of temperatures throughout the year, from below freezing on a cold winter’s day to temperatures in excess of 200°C on a hot summer’s day. It is these high temperatures during the summer months which can lead to the premature degradation of the thermal fluid. Therefore it is important to choose a thermal fluid which has been specifically developed to withstand these extremes of temperature.

Sentinel says it has developed a unique and highly effective cleaner for solar thermal heating systems  – R200  – which is now protected by Patent  (GB 2462707) – which helps to solubilise and remove degraded glycol from existing solar thermal heating circuits.

According to the company, where degradation has already occurred, twenty minutes cleaning with Sentinel’s R200 Solar System Cleaner, particularly when used with the Sentinel Solar Flush unit, will disperse and remove deposits from the system and prepare it for the addition of fresh thermal fluid, such as Sentinel R100.

Effective cleaning and protection will ensure that the operation and life expectancy of a Solar Thermal System is optimised and will provide long lasting frost protection throughout the winter months.

Sentinel adds that using a high quality thermal fluid such as R100, will ensure your Solar Thermal System will function at the highest performance level providing a cost effective and energy efficient way of providing heat and hot water for your home.
