I may come to regret this, since, knowing this forum, I suspect that I may well attract comments/advice/'warnings'/whatever which are not actually answers to my question - but, nevertheless ...
... I am working on a house in which the only hot water is that from a couple of ancient 'over-sink' instant electric heaters, either or both of which may be on their last legs.
The situation will eventually be addressed, almost certainly by installing a combi boiler in the kitchen, but that could be many months, or longer, down the road, so I am considering temporary measures.
I'm therefore considering temporarily installing a 'plumbed-in' electric instant water heater in the kitchen, probably of around 10 kW. That would presumably work adequately for the taps in sinks, basins and baths (even if fair slow flow into a bath!), but I'm wondering if anyone knows whether it would also 'work' reasonably with mixer shower?
The bathrooms are immediately above the kitchen, and no water (hot or cold) is needed other than in those places, so pipe lengths will be relatively short. Use would only be pretty 'occasional', so the excessive cost of electrically heating the water would not be a major issue (and it would be no different from what is happening already, anyway)
In case Mr Jobsworth is around, there is already an (unused) 40A shower circuit present, which was installed 'just in case' an electric shower was ever needed (which I doubt it ever will), so I could use that circuit for a water heater - so that, since what I'm suggesting would require neither a 'new circuit' nor any electrical work in a bathroom, it presumably would not be notifiable, at least as far as Part P is concerned.
So, the question is really simply that of whether (and 'how well') such a water heater would satisfactorily run a mixer shower. Since I'm talking about a power similar to that of an electric shower, I would have thought it would 'work', but I'd be interested to hear other people's views (and, obviously, other people's experiences of similar arrangements, if there are any such people!) .. and please remember that I really am talking only of a fairly 'temporary' arrangement.
Kind Regards, John
