Primarily referred to as glycol, the product comes in different formats, however SunEarth recommends usage of the Dow Chemical Dowfrost HD propylene glycol heat transfer fluid (HTF). Solar water heating systems have the unique characteristic of producing very high fluid temperatures during summer stagnation conditions.
A solar thermal system is a low maintenance system but it is still recommended that it should be serviced annually. To find a local solar thermal service engineer, please visit Will the solar panels still work on a cloudy day?
No. The solar fluid used in a Grant solar thermal system is a 40% propylene glycol solution. This provides frost protection for the collectors and external pipework down to -25°C. How often do I need to replace the fluid in my solar installation?
No. Grant Solar Thermal systems require only basic maintenance in order to ensure that they continue to give trouble free operation. How often should a solar thermal system be serviced? A solar thermal system is a low maintenance system but it is still recommended that it should be serviced annually.
Selecting an efficient, stable fluid to transfer heat from the rooftop panel down to the hot water heat exchanger is a key step to optimizing any solar thermal hot water system. Solar rooftop panels can reach temperature exceeding 300°F (149°C).
The solar fluid is a non-toxic 40/60 propylene glycol and water solution which has been specifically developed for solar thermal applications to protect the systems from freezing.
In smaller systems for DHW heating, heating contractors should change or refill the solar medium every ten years on average. If it is a solar system for central heating backup, this might need …
Ideally the fluid should not corrode the pipework and other components in the system, and the fluid needs to be stable so that it does not need to be drained and replaced regularly. If there is any chance of the fluid coming into direct …
How Does Solar Thermal Work: It uses sun''s energy to create heat, which is transferred to your home''s or place of business''s heating system. ... The controller will …
Before diving into our complete guide to solar thermal panels, we should first lay out the difference between solar PV panels and solar thermal panels: ... Heat transfer fluid – Within the collectors, a heat transfer fluid, …
Solar collector covers are sometimes used to control the temperature of the process so the installer does not have to deal with scalding hot solar fluid on clear sunny days. Some installers may wait until a cloudy day or …
Selecting an efficient, stable fluid to transfer heat from the rooftop panel down to the hot water heat exchanger is a key step to optimizing any solar thermal hot water system. …
When there''s a big enough difference, a controller turns on the pump to move the fluid and heat the water. Solar thermal panel. ... (30 to 60 litres). Alternatively, you can add a cylinder with a solar coil or retrofit a solar coil to your existing …
Solar thermal panels are designed to be durable and long-lasting. On average, well-maintained solar thermal panels can last around 20 to 25 years or more. Regular maintenance and proper …

Solar water heating systems have the unique characteristic of producing very high fluid temperatures during summer stagnation conditions. In a forced circulation system, a …
Changing the heat transfer fluid in a solar thermal system is a critical maintenance task that ensures the system operates efficiently and has a longer life span. We recommend the fluid is …
Regular maintenance and monitoring of the Heat Transfer Fluid in your solar thermal system is essential for optimal system performance. It is important to inspect the fluid regularly for signs …
Specific heat capacities in the UK are typically given in British Thermal Units (BTU) per pound degrees Farenheit (BTU / (lb.F)). One BTU will raise the temperature of 1 pound of water by 1 …
Most solar thermal systems use antifreeze as the liquid to transport heat from the solar panel to the cylinder. However, there are a few drain back systems that only use water. The antifreeze …
Ideally the fluid should not corrode the pipework and other components in the system, and the fluid needs to be stable so that it does not need to be drained and replaced regularly. If there …
We recommend that the glycol concentration in your solar thermal system is checked during the annual service of the system. In general, it is recommended that the glycol fluid is replaced …
