It is well known that solar thermal systems are low maintenance, especially when compared to other types of heating systems such as gas or oil. However, basic maintenance is recommended to help a solar thermal hot water system work efficiently and trouble-free. In this blog we cover some of the steps that should be carried out annually to maintain a solar thermal system.
Sealed systems are a common occurrence with many homes opting for this type of central heating set-up. Oil Boiler heating engineers who design and work on such systems need to understand the importance of providing sufficient system expansion capacity. In this blog, Phil Stanley, Grant UK’s Training Manager, takes a closer look at this topic and explains the importance of the expansion vessel in oil boiler heating systems.
It is sometimes necessary to bleed air between the oil supply and the burner of an oil-fired boiler. This procedure is usually required after the system has run out of oil and the burner has ‘locked out’ and stopped. After the tank has been re-filled, the air trapped in the oil pipe needs to be released so that fuel can reach the burner and allow it to re-start. This blog is designed to talk you through the steps involved in bleeding a burner.
