Kettle wars, day #93

So I've blipped before that we have a zip tap, which breaks down, is fixed, lasts for a day, breaks down again. This has been replaced by a kettle recently. Last week a solution was sought, whereby a boiler was suggested. There is nowhere to site this so the joiner has produced this mock-up. Someone suggested having two kettles, but this was apparently deemed unthinkable. So now we have a non-working zip tap, a kettle and a pretend boiler.
Who knew boiling water was so problematic?
