Instantaneous Water Heater advice

I would like some advice on an Instantaneous Water Heater that can provide hot water for a bathroom sink and a kitchen sink (1 heater, 2 appliances). The hot water pipe length from the heater to each appliance is roughly 2 metres.

This will be for a small outbuilding and so the bathroom sink will be very small although the kitchen sink will be standard size.

Any suggestions on a heater or wattage necessary that will suffice to supply a reasonable flow rate?

 

You need to refine your requirements , Gas or Spark

Ok missed that chk

 

Ariston units are good but it will depend on your planned usage. Crown make some slightly larger stored hot water solutions

 

The Ariston units are cheap and cheerfull , for the money , theres nothing wrong with them

 

I like the hyco units. Never had a problem when fitted correctly.

 

@Dan Wright . Hi mate, is it for diy install?

 

Dan are you sure you want an Instantaneous water heater or as most seem to be suggesting a small storage multipoint?
You will get very very poor flow rate & have to run a large cable if you go for instantaneous.
15Litre 2-3kw is the minimum for one kitchen sink, if there is not much chance of them being used within 30mins of each other, that should do. If not go larger with the storage capacity only.

New Heatrea eco multipoint look good they have intelligent elements & good insulation which might help.

 

If you go down the electric route, what supply capacity do you have to this outbuilding ?
