Heating hot water in the summer

    Hi all,

    See my previous post...

    http://www.boards.ie/vbulletin/showthread.php?p=91749615

    So, after having another look, my plumber gas found out that if i were to fit a summer valve (i.e. a valve that allowed the hot water from the boiler to only be fed to the cylinder) we would need to lift floor bards to get at the correct location where the pipe feeds split.

    He has advised that we could fit thermostat valves on the radiators and during the summer months we can just turn down these valves so that the majority of the water goes to the HW cylinder to heat the water. He has quoted approx €40 per rad and we have 11 rads so around €450 all in.

    Does this sound like a sensible option?

    Thanks.

    No! If you want to do this ie. circulate hot water round the system but not actually go through each of the radiators then turn off the radiator valve which is on each radiator already.

    That will be only €250 thank you!!:D

    I would get a plumber to do the zone split and then fit TRV's to better controller individual rooms. Even better split down stairs and upstairs (beds/living) for even better control and improved efficiency while he has the boards up. Don't let him put valves where you cannot get to them.

    Cheers for the response.

    My thinking was that I would likely get the TRVs fitted anyway as it is a pain in the hole to try to adjust the temperature of the rads with the normal valves.

    During the summer I would prob have the majority of the rads off (except for cold rooms) and just have the heating on in the morning for an hour to temper the place.

    The remaining question then is would that system be convenient enough if I needed water at 6pm during the day. Should I get the immersion fixed anyway as a back-up?

    Cheers.

    It is a pain in the hole because you cannot do it. TRV's are for automatic temperature controls on individual radiators not for manually turning them "up or down".
    Search my other posts or "TRV's" save me repeating it all here again.

    And yes get your immersion fixed now. It is cheap to buy one and one day you will be pleased you did. A decent plumber should be able to replace pretty easily unless a numpty installed it in the first place.

    Without a room thermostat or zoning each time the boiler is on you are heating the whole system up thus wasting money.
