Are boing water taps worth it (environmentally)?

Just wondering if people with PV especially think the Quooker type boiling water taps are a benefit?


It's convenient for sure for cooking and tea/coffee and there's no surge in demand like when one boils with a kettle/induction hob so they would arguably make better use of PV output with low but constant demand.

On the flip side they are expensive and presumably leak a small amount of heat throughout the day and night.

Could it be lumped into a Deep Retrofit application along with solar panels?

they have a 2.2 kw element

511kWh energy usage a year quoted on one instant hot water tap. Not sure if this is constant or peaks (2.2 kw as dathi points out) after water is replenished, so just like a kettle but in reverse! PV Generation may help offset some of this but not at night or in winter unless you have batteries?
One article I read reckoned that energy usage is on a par with an Electric kettle overall but it can save water. My friend got one recently though and loves it! So as a convenience it's a clear winner, environmentally - less so....I doubt you'd get a grant for it !!!

That seems very high. Given that the average Irish household consumes 3500kWh per year

It needs to be running at peak power for 40 minutes a day on average to consume that.

A number of them have appeared in the works kitchenettes, they're great.
I'm surprised the Health & safety freaks haven't plastered them with warning stickers!

Two people I know had them. Two different manufacturers. Both broke down in a short enough time span.
