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 a solar inverter for water heating?

These systems have a solar panel inverter that converts Direct Current (DC) from the solar panels into Alternating Current (AC) that can be used in your home or business. Solar thermal panels, meanwhile, generate heating and hot water from energy from the sun. These are the panels you’ll need for solar water heating.

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.

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.

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.
