    Good evening,
    What tipe of relief valve would I need to put on tubular pannels on roof. I took the old one off as the internals was totally blown out. It would need to withstand our weather conditions as it is fitted to the pannels ontop of the roof. The system runs at 1.5 bar. what should the setting of the valve be aswell?

    Any help would be really great...

    What you need is an installer with a D3 qualification, you are DIYing with a pressurised system and if you get it wrong could end up with serious consequences, IE a good part of your house demolished.
