    Unvented cylinder - usage question

    We have an unvented cylinder with a Horstmann Electronic 7 timer. The cylinder only serves a wet room which is very rarely used. The rest of the house is served by a Vaillant combi boiler. The timer on the cylinder is set to heat up water 3 times per 24 hours, which I think it is the default...

    Advantage of unvented cylinder outweigh the disadvantages?

    I have come to my decision I might as well do my G3, even if only for maintenance jobs. Question I have is WHY we are fitting so many of these unvented cylinders i.e. 27 gallons /117l size or above (I'm not disputing the need for 10l unvented 'cylinders'). They 'need' annual servicing by a G3...

    Do I need G3 to repair a 10l unvented cylinder?

    Hi. Potential customer has a leaking 10l Ariston Europrisma cylinder. Probably just a flange gasket or the magnesium anode needs replacing. While I feel this is easily the sort of task I can tackle as I am very good at mending things, I get the impression I'd need my G3 to install such a...

    Insulate a Unvented Cylinder

    Hi I have a warmflow unvented water cylinder (indirect 250) in a hotpress. It was installed two years ago, but never had any lagging put around it. Wanted to ask if that would have been for a reason why it wouldn't have, and also would insulation be a good idea to warp around the tank? Thanks

    Is there a standard for the above?, ie primary flow rate, primary flow temperature, reheat time from X degC to Y degC, continuous flow rates at different temperatures and coil area.
