What is a solar hot water system?

A solar hot water system is a renewable energy technology that harnesses the power of the sun to provide heat for domestic hot water purposes, much like traditional solar panels. The basic principle behind solar hot water heating is the conversion of sunlight into heat energy.

Should you install a solar thermal system for heating hot water?

Installing a solar thermal system for heating hot water is a good move for the environment. But before you go ahead, it’s essential to know all the facts so you can decide if a solar hot water system is the right choice. First, it’s important to point out that there are two types of solar panel systems:

How much hot water does a solar water heating system produce?

Generally, a solar water heating system can produce between 40-70% of the hot water needed for a family of 4 annually. In a similar way to solar panel efficiency, exactly how much hot water you will benefit from is difficult to estimate, however, as there are a number of factors to consider:

What are the different types of solar water heating systems?

There are two main types of solar water heating systems Active systems use pumps and controllers to circulate water through the collectors, which allows for more control over the temperature and flow rate of the water.

How much does a solar water heating system cost?

If your home is a listed building, or in a conservation area or national park, you may have more restrictions. The cost of installing a typical solar water heating system is around £6,000. Costs will depend on whether you choose evacuated tube or flat plate collectors, as well as the size of the system.

Is solar water heating a good idea?

In the summer, it should provide around 90% of your hot water requirements, dropping to around 25% in the winter. Sunlight is free, so your hot water costs will be reduced. Solar water heating is a renewable heating system and can reduce your carbon dioxide emissions.
