How do I install a solar hot water system?

(Learn more about the types of systems available here.) In most solar hot water installations, the first step is to put the solar collectors in place on your roof. Most solar hot water collectors are similar in shape to photovoltaic solar panels and will lie flat on your roof.

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:

Are solar water heating panels cost-effective?

Although it is also possible for these systems to provide some space heating, this is usually only a small amount of the total heating required. So, the principal benefit of solar water heating panels is in providing hot water and installing solar thermal water heating can be cost-effective in businesses that require a lot of it.

Do you need planning permission to install a solar hot water system?

For example, in the winter, the solar thermal system may only produce a fifth of the hot water needed. Some buildings may need planning permission to install solar thermal panels on the roof. Residences that have combi boilers will also need to install (and find the space for) a solar hot water cylinder.

What is solar panel water heating?

Solar panel water heating was the first solar technology to be commercialised in the UK. This guide looks at the technology and explains how it works.

Where will a solar thermal expansion tank be installed?

The expansion tank will be installed on the solar thermal loop (normally near the water tank and pumping station); this prevents pressure changes in the system damaging components. Special insulated pipes will be installed between the pumping station and the solar thermal collector.
