Under sink Water Heater options

[Sfc]

Need to fit an under sink water heater to feed one kitchen sink. Could anyone recommend a decent Heater to fit at all? Would a vented heater be suffice or do you think it will have to be invented. Cheers

I don't think anything will have to be invented as there are loads of options already on the market
Depends how much hot water you want really, a 15l undercounter unvented will be relatively inexpensive but is not for heavy use and needs to be turned on 40 minutes before using the tap. Also as it's 15l a G3 ticket isn't needed afaik.

As above, recommend Ariston 10 or 15 litre under sink water heater
