    JG Aura 230v Thermostats call for heat at midnight for 5 minutes!

    To be honest I think it’s a software glitch or a pump exercise programme! Setting a separate one channel programmer to kill the switched live would cure the issue. Or get hold of their rep. And ask him/her/it.

    Odd whooshing noise

    The white silocone washer on the left. Or the complete valve. Look on fixthebog.co.uk for the same valve. If the existing washer has pimples, pop them with a pin and squash the water out until flat. https://plumbinbits.co.uk/product/fluidmaster-dual-flush-valve-pro820uk/

    Expansion vessel failure

    It’s much the same as tyres deflating when a car isn’t being used. Think it’s called Graham’s law of absorption or something similar.

    You may have been the only house on a run with an open vent prior to new stack. Waterless trap is the way forward and does work. They were invented for crap plumbing technique rectification! Say no more!

    Heating and hot water on at the same time

    If you trust a smart meter then DON’T. Take meter readings instead. Then study pure mathematics to doctorate level and work it out yourself. Smart meters are not smart! They always favour the supplier. Imo.

    Expansion vessel failure

    You may also have a faulty secondary heat exchanger if the pressure rises overnight. Also a faulty filling loop. Get it diagnosed by a third party engineer. The guy who did the safety check only did a safety check. If you didn’t employ that person you have no recourse with them. Just get it...
