BIG Terminal Water Heater.

Zoomup

I installed one of these yesterday. It works well as a hand wash water heater. It is well made and stylish. But why are the electrical terminals so BIG? Perhaps the makers have used shower terminals as they can easily take 10.0mm2 cable.

    I think that a similar design of water heater is available in 7 kw, so as to give a better flow rate and fill a kitchen sink in a reasonable time.

    Perhaps it is simpler to use the same terminals for both the 3 kw and the 7kw versions.

    Probably so that they have to carry less assembly and spare parts.

    Did you observe that the notices inside refer to a “shower”. I thought odd to be using flex for the supply: I would like to have seen ferrules in that case.

    Only upon a second viewing Chris.  The terminals that I came across were bigger than the ones shown in the new hand wash unit in the video clip. The existing flex had ferrules fitted, but I could have put 10 of them in the big terminals. Certainly a doubling or tripling over of the wires will be needed if no ferrules are fitted.

    Presumably Zs measurement or RCD testing isn't required or recommended.

    The video is a manufacturer's “how to” on replacing an older model with a newer model.  The video gives no hint that (at the very least) now would be a good time to check there's an RCD present and that the test button does something.
