Installing solar panels in the UK on the roof is not the greatest challenge, compared to the complex work of adjusting solar heating with the existing heating system inside the house. Combination boilers are the most popular choice of boilers among the Britons – 77% of the new boilers sold in the UK last year were combis, and approximately 50% of British households have a combi boiler.

While most people tend to use hot water mostly in the mornings and evenings, solar energy lands on the solar panels during the daytime. Therefore the water that is heated up by solar energy needs to be saved up for later use in an additional hot water cylinder. The solar energy available varies from day to day so it is also important to use the boiler to bring the water to a sufficient temperature on days without the contribution of solar energy.

Whether or not your solar thermal system can be matched with the combi boiler, will depend greatly on the model of the boiler you have installed. While some types of combi boilers accept pre-heated water, others do not. Only those combi boilers will accept pre-heated water, which have been fitted with temperature rated components on the boiler’s incoming side. Approximately 45% of combination boilers will not accept pre-heated water while others accept the intake of water up to certain degrees. It is the duty of the boiler’s manufacturer to inform you about the maximum temperature of pre-heated water that your combination boiler can accept.
