    Oven trips RCD when turning it off

    Sorry I missed the continuation of this thread. I suspect that the reason for the trip to occur at switch off is that the mechanical design of the main oven switch (which is double pole) in practice switches the neutral out of the circuit first, fractionally before the phase. In that moment...

    Oven trips RCD when turning it off

    Quite possibly a failing element. I had exactly this with a previous oven.

    Expansion gaps for engineered

    Hi all, I would like to install a 15mm thick ply/oak engineered wood product into my living room which is about 3.5 m x 3.5 m. The product is click lock. On one wall there is a 3m wide internal bifold door set which has an oak bottom track, and it would look considerably nicer to lay the...

    Recommend a combi.

    Most plumbers fit the boilers they have worked with the most and done training on. I think it’s lrobably best to choose a good, trustworthy reputable plumber and see what he recommends.

    Plasterboard was used in 1930’s housing, the ceilings of my 1936 property are.

    Hang internal bifold doors from RSJ?

    my house has a single storey extension. The living room spans in to the extended part with an opening in the original rear wall of the house which is about 3m wide. The building control drawings for the extension state that there is an RSJ for the inner leaf of brickwork, with a welded plate...

    zone control using 2 port valves

    It should detect, and it will. It’s not a complex device. Your rads may be balanced - in that the lockshields have been adjusted for 12, or 20 degrees temperature drop above the radiator, but that probably isn’t enough. When the TRV shuts off, the radiator is still hot and will then cool by...

    zone control using 2 port valves

    Sounds like your radiators might need balancing. Don’t knock evohome until you’ve tried it. It works very well. Batteries in the TRV heads last 2 years; room temperature control even from the TRV heads is excellent (because, as stated above, radiators actually convect most of their heat). 12...

    Is there a maximum 15 mm pipe length from the 22 mm ring?

    Yes, that would be a really good thing to do.

    Is there a maximum 15 mm pipe length from the 22 mm ring?

    It'll work, just about. It's pushing it though. You'd be best doing a separate run for each radiator if you can. You may well have to balance other radiators to get the new ones to heat up well (see the FAQ at the top of this forum). The "debate" above is because a pipe can only flow a certain...

    Is there a maximum 15 mm pipe length from the 22 mm ring?

    If he has a one pipe system, it shouldn't be extended, it should be replaced!!!

    2 x 16 amp kitchen appliance on one 32amp mcb?

    I have AEG ovens. It's all Electrolux group, same as zanussi. The instructions are awful. One of them doesn't even mention power or electrical connection at all. Both of mine are wired in 2.5 mm into an outlet which is fed in 6mm from a 32A RCBO. It's perfectly safe, and there are thousands...

    Boiler losing pressure only when heating is off

    If you're losing pints and pints every day into a 5' patch of concrete, that floor will probably be wet.

    need advice on 10mm Rad system, childs room too hot

    Moving that stat is the best plan but the target location needs to be right ( representative of average temperature and influenced by a radiator, but not in draught from windows or doors). That's not necessarily where you want to put it though. Your first port of call should be to throttle...

    2 x 16 amp kitchen appliance on one 32amp mcb?

    Might well be that it wants a minimum 16A, not a maximum.

    Installing a radiator up high, waste of time?

    But it only controls the the fan. The heater itself is a permanent bypass.

    Installing a radiator up high, waste of time?

    Yes. Called hydronic. Myson do them. The downside is you can't fit a TRV to them so they are basically uncontrolled
