    Ultra heat rads and EPH trv's any good?

    Hi all Been quoted to replace 12 rads and valves, when I asked what they use. He said ultra heat rads and EPH trv's. Anyone used ultra heat rads or EPH trv's? Would you expect them to be any better than Screwfix Kudos?

    Tower Trv's

    Smart TRV's

    When I moved into my bungalow 10 years ago the central heating was a nightmare. Hot water cylinder on the ground floor and presumably lack of general use of zone valves back in 1971 when the system was installed meant that 2 pumps had been installed. Firing of the boiler was controlled by a 4...

    TRV's & Boiler+ (Boiler Plus)

    Evening All! I am having a thick moment. Again. What does boiler+ say about installing TRVs when swapping a boiler? I have heard some say that you (always) need to fit TRVs when swapping a boiler. Others say that you dont now don't need TRVs with the uprated Boiler+ controls. Any thoughts? J

    Upgrade CH system: what trv's ? a

    Hi, I'm not a plumber but a retired householder who used used to do some of my own plumbing.

    TRV + Room thermostat - Why?

    So I am not a plumber but have reasonable technical mind. Can anyone explain why have a 'room' thermostat and TRV? For example, our bungalow has 5 rads with TRV and the one in the bathroom no TRV, plus we have a 'room' thermostat in the hall. If the hall TRV is set lower than the room stat...
