    Better cylinder thermostat for a 3 kW immersion heater

    For reasons which I can explain if necessary, I want to replace the existing "integral" DHW thermostat for the electrical immersion heater with the type used to control a CH boller. I would leave the over-temperature cut-out in circuit. I have bought a Salus CT-100 strap-on pipe/cylinder...

    380v immersion heater in UK

    I need a 3 phase immersion heater with a DN32/42 mm thread for a commercial pasteuriser. The only ones that I've found so far are not inexpensive! I have now found several for sale on line which are far more affordable but they're rated at 380 volts and advertised as heaters for PV water...

    Immersion heater - New switch install help

    Hi, I'm about to switch to an energy tariff whereby i think it would be better/cheaper to heat my water via my immersion heater and not my gas boiler. I have a plain old switch attached and wanted to install a new WiFi-enabled switch or, failing that, a timer switch. I've just opened up the...

    Using solar panel DC output to feed immersion heater?

    Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter? Evidently, a changeover relay would be required to utilise the usual 240V AC supply at times of low or zero...

    Cylinder Immersion Heater Tripping

    Hoping someone can give me some advice. My cyclinder immersion thermostat is tripping every few days. It hasn't been used for a few years, but now, because I got Solar panels and an Eddi connected, we've started using it again. I've established that the Eddi, nor the top thermostat, is faulty...

    Immersion heater failure

    I've just rewired my old I.H. and it seemed to be working fine although it was quite noisy. Something tripped the RCD last night and I suspect it was that. Now there is nothing - No noise at all. I don't have the meters to test it unfortunately. Is it likely that it's packed up completely with...

    Hello, everyone I want to install a second unvented hot water cylinder. The existing (indirect) dhw cylinder has a backup immersion heater on a dedicated circuit with a timer.
