    Sanity check..., gravity hot water and pumped radiators, should they work together

    My solar system was installed 8 years ago - the contracts were much more "interesting" then, and the contract holds for 25 years. Would be a very different contract for a new system today

    Points taken However with solar power you are paid for all the power you generate, whether you use it locally or feed it back to grid, so not a choice to sell or use, you either sell and use or sell and don't use... So on a sunny day it produces 3Kw. I am paid for 3Kw regardless. I have choice...

    Sanity check..., gravity hot water and pumped radiators, should they work together

    There are two heat sources and two coils both for domestic hot water (DHW), wood and gas. The system was installed many years ago, I did test it then, but not really used gas for hot water much due to wood burner and unlimited free wood. We also use the immersion heater as we have PV solar...

    Sanity check..., gravity hot water and pumped radiators, should they work together

    gravity fed wood burner circuit works (can't see pipework on photo - on back of cylinder, same 28mm fittings) gravity DHW does not seem to work - seems circuit is blocked I understand the logic and location of the airlock on heat exchanger input at top To remove I need to force water through...

    I am not a plumber but understand the pipe has to rise for gravity to work. Around the back of the boiler (photo doesn't show) are similar 28mm pipes for wood burner circuit which works well.

    Sanity check..., gravity hot water and pumped radiators, should they work together

    When I set the controller to call for hot water it activates the valve so valve is open. The logic being in winter we can have radiators on without the boiler heating water. The wood burner produces more than enough heat to heat the water, but only heats lounge so we need radiators on... In...

    Sanity check..., gravity hot water and pumped radiators, should they work together

    I hope someone can comment on my setup and let me know if I have a problem or not ! I have old gas central heating system, all was working: gravity fed hotwater heating radiators via pump. We then had back boiler fitted to wood burner and replacement cylinder with 2 coil element type fitted...
