    We bought this for a detached annexe and it does the job perfectly. Plenty of very hot water for the kitchen and bathroom sinks. Fits nicely under the kitchen sink too.

    Using this to heat water for a sink in a bathroom and a kitchen sink for an annex. Easy to install, hard wired to a plug socket and attached to the wall. Hot water pretty much instantly. Excelllent bit of kit for the job
