    Hi all,

    What Im wondering is what all can a solar system heat, from what ive looked into its really designed for hot water and can also be used for under floor heating but is there any other uses?

    Can you use it to heat the radiators? Ive looked on various websites of company dealing in solar systems and none state they can heat the radiators...

    If anyone could offer any help that would be great!

    In Ireland, we don't have enough light in the winter to get useful amounts of heat from solar, so I would dismiss space heating with rads or under-floor. Some would differ on this, and yes, there are occasional sunny winter days when a huge array of panels would heat your house, but the payback for that sort of system would be ludicrous and your money would be better spent on insulation.

    Solar fills a useful niche. In winter, your heating system heats the hot water fairly cheaply and efficiently. In summer, when the heating is off, your hot water is more expensive, because in most cases it comes either from an immersion heater, or using a boiler in the shed and heating up boiler, flue, pipes etc., just to heat a hundred litres of water in the hotpress.

    Solar displaces this more expensive hot water in the summer. Trying to use it to displace cheaper space heating at a time when daylight is lower makes no sense to me. Q
