Solar tank heating

What is solar water heating?

Solar water heating (also known as solar thermal) is a low carbon, renewable technology that uses energy from the sun to warm domestic hot water. It’s a sustainable alternative to heating systems that rely on fossil fuels, such as oil and gas fired boilers. Solar water heating systems use solar panels, called collectors, fitted to your roof.

How does solar thermal water heating work?

The solar thermal technology is designed in a way that the heated water is stored in a separate tank for preheating or a regular water tank until you need it. Even if additional heat is needed, the regular water heating system jumps in and provides the extra heat through electricity or fossil-fuel 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:

Do you need a solar water heating system?

Just remember that you’ll need a boiler or immersion heat to keep your hot water supply going – especially during the colder months. A solar water heating system should provide you with around 90% of your hot water needs the summer and 25% in winter. There are a few things you need consider to get the most out of your solar water heating system.

How much hot water does a solar thermal panel produce?

The specific amount of hot water that is produced depends on the time of year. During the summer, the solar thermal panel can produce most or all of the hot water demand. In the spring and autumn, by pre-heating the water in your cylinder, your solar thermal can reduce the amount of energy needed to heat your water.

What happens if you leave a hot tank on a solar system?

If you leave it like this, your system will always start the day with a hot tank and there’ll be no water for the solar panels to heat during the day. Your installer should advise you on how to set your hot water controls to get the most out of your new system, whatever time of day you use hot water.
