Where should the hot water cylinder be sited?

Ideally, as close to the solar panel as possible — to limit heat losses.

You will need to identify a route for the hot water pipes to get from the solar system down to your household plumbing. Your plumber may advise on the best way to do this.

If the distance between solar panel and hot water cylinder is greater than 12 metres, then it may be necessary to purchase an optional larger (3 speed) pump.
