Can i switch my new boiler off once a day?

Hello

Just got a greenstar 25i worcster fitted, can i turn it off for 8 hours a day when im out?. I belive even leaving it on number 1 all the time is still more costly by some way, versus switching it off once a day!! Allso will turning my boiler off during the day affect the boiler pressure as it seemed to, the first week it was fitted...

Any intelligent suggestions welcome

CHEERS.

    There is no pilot light like old boilers, so you are not wasting gas.

    Frost protection will not work if you switch it off.

    If you are really unlucky, your power on surge protect capacitor is a dud, and has only a hundred on/off in it, before it blows.

    You mean you haven't got a timeswitch and/or a room stat? Did the installer say nothing about updating the controls? Naughty.

    And an aside, what type of inhibitor is added? Look for a label or read the Benchmark logbook.

    CHEERS.

    Been retired a while so bear with me, I'm a little rusty and may need flushing with a glass of red wine ;)

    1) can i turn it off for 8 hours a day when im out?.

    Yes you can, though as has been mentioned, if it is switched off you won't benefit from two features (a) the frost protection, this will fire the boiler up to protect it from freezing and (b) a feature that runs the pump once every 24 hours to prevent it from seizing.

    2) I belive even leaving it on number 1 all the time is still more costly by some way, versus switching it off once a day!!

    By number one I'm presuming you refer to the hot water temperature setting, not the central heating temperature.

    I presume your boiler has the ' keep hot ' function, this keeps a small quantity of water constantly hot within the boiler to give almost instantaneous hot water at the taps.

    So yes, with this function enabled, even though you don't use hot water for a week it will ' cost you ' . :eek:
    There is a way round it. :idea: :D

    You may have a button on the boiler with something like ' ECO ' or ' Pre Heat ' on it.

    With your boiler switched to ECO mode it won't keep a quantity of water constantly hot within the boiler.

    The disadvantage, you wait a little longer for hot water to arrive at your tap :(.

    The advantage you end up with more pounds in your pocket :dance:.

    Check your user manual for Eco or Pre heat options, you usually have to depress the button and the ECO light comes on, or the button illuminates, to let you know you are saving money. :j

    3) Allso will turning my boiler off during the day affect the boiler pressure as it seemed to, the first week it was fitted...

    Yes it will.

    Nothing to worry about though, I'll explain.

    When your boiler is cold, the pressure will be approx, 1 bar.

    When your boiler is at its hottest it may be approx. 2 bar.

    As the water heats up, the pressure will rise, as it cools pressure will decrease, through out the the day the pressure will rise and fall constantly as the boiler operates.

    As long as it does not go below 0.5 bar or higher than 3 bar everything works as it should.

    However if it should go lower than 0.5 bar or higher than 3 bar safety features kick in to release excess pressure and shut down the boiler should there be insufficient or excess pressure.

    The boiler controls themselves use minimal current.

    To summarise, best left switched on, use the ' ECO ' function for hot water if fitted, study the central heating boiler manual, it should have been left for you.

    Hope this helps. :)

    What controls do you have fitted in the property?
    Room thermostat or programmer? Thermostatic radiator valves? Any modern install should have these fitted.
