point of use water heaters

Gers

Once again just asking for some advice and hope someone can help.

The 'new' house we are in has an immersion water heater. No mains gas, just electricity on economy 7. We've had the bath removed and had an electric shower installed instead so we have no need to heat a whole tankful of water overnight.

I would like something like a Qooker Fusion thing installed in the kitchen, it has boiling, chilled and warm water options and would be great for just washing hands, rinsing and hot drinks etc.

If anyone has one, or something similar, I'd appreciate your knowledge about the good and not so good things about it/them.

Thanks

Gers

Gosh...128 views and no comments. I'll take that as there are no negative aspects of this type of water heater.

The only problem I could foresee would be scale build up, but no doubt you are going to say naturally soft water supply ?

Scale in hard water areas can be a problem with electric elements .

Why take it as no replies means 'no negative' comments?

Possibly a case of not a lot of people are aware / know of / use Qooker Fusion or similar.

Single point water heaters are generally more commercial than domestic.

Less common these days so there's probably less opinions out there for you

You already have the best form of electric hot water, a whole tank of piping hot water delivered to you at a third of the cost (E7) of a point of use heater.

You are not heating a whole tank every night. The tank is insulated and very little heat is lost. You are only paying to heat the bit of water you used the day before plus a little bit of loss.

Point of use heaters will be very slow (like a dribble) unless they are high power and will then need their own cabling to the consumer unit.

Stick with what you have as point of use heaters are total rubbish.

Fit an External Immersion like this (other brands are available) so you don't have to heat a "whole cylinder" of water..... (Not recommended for hard water though...)

The 'whole cylinder' is only heated once anyway, the rest is just a small top-up each day. At E7 rates it is nice cheap hot water.

Thanks for the avalanche of replies.

Having a tankful of hot water is something I want to avoid - we are both out all day, are away from home for three days a week and will be moving away from E7 soon as the storage heaters have been removed.

We are in a soft water area - west coast of Scotland so scale won't be a problem.

Already got an electric power socket under the kitchen sink.

The external immersion looks interesting - thanks for that, will investigate this more.

I've seen many hot water points in houses, not Qooker but mainly Zip Hydro units which are not as functional as the Fusion one.

Once again, thanks for the comments, they have given me things to think about.

If you are moving away from E7 and storage heaters, what are you getting as a replacement?

It wont be good enough. Any point of use heater that will run off a socket will be so slow it will take about 15 minutes to fill the bowl and will be cold by the time it is done.

I would very strongly disagree with this. We have the same set-up as the OP and find that the water loses heat very quickly, despite the cylinder being fairly new, with plenty of insulation. If we put the immersion on in the evening until the water is warm enough to wash up with, by morning it is cold - not quite as cold as water from the mains but not far off. It feels incredibly wasteful, although I suspect the actual costs aren't much - certainly not enough to merit the hassle of replacing the cylinder with a more efficient system.

Sorry, but there is something wrong with your system.

I had a far from well insulated tank (no foam, just a thin jacket and a quilt that I wrapped around it), and it would stay hot right through until it's next top-up during E7 hours.
