 Also known as solar thermal, a domestic solar hot water system is one that absorbs the sun’s energy and transfers it to the water in a well-insulated storage cylinder, so that you have hot water when you need it. Solar thermal is different from solar [photovoltaics](/soel/solar_electricity), as solar hot water panels (usually called ‘collectors’) don’t produce electricity - they have water flowing through them, which they heat directly. Also known as solar thermal, a domestic solar hot water system is one that absorbs the sun’s energy and transfers it to the water in a well-insulated storage cylinder, so that you have hot water when you need it.

 Solar thermal, and other renewable energy sources, doesn’t involve the burning of fossil fuels, which releases nitric oxides, nitrogen dioxide and sulphur dioxide into the atmosphere. This causes acid rain which damages forests, wildlife and human health, and acidifies the oceans; it also releases carbon monoxide, nitrous oxides, lead, particulates and hydrocarbons, which pollute the atmosphere, and cause damage to plants, ecosystems, and human respiratory health. Solar thermal, and other renewable energy sources, doesn’t involve the burning of fossil fuels, which releases nitric oxides, nitrogen dioxide and sulphur dioxide into the atmosphere.

 Your installer will leave you with a little checklist to go through every couple of months, just to make sure everything is working properly (if you install yourself, you’ll know what these are). It might be a good idea to have a full maintenance check every 5 years or so. Your installer will leave you with a little checklist to go through every couple of months, just to make sure everything is working properly (if you install yourself, you’ll know what these are).
