Hot water isn't

[ColinM50]

Had a new kitchen installed last spring and while we're happy with it in general, one thing really bugs us. That's the loooooong wait for hot water to arrive at the kitchen tap.

Is there some form of instantaneous boiler that I can install under the sink to provide hot water?

I don't want the old fashioned gas or electric geyser type thast my nan had, just some form of heater that can supplement the existing

TIA

How long is the run from the boiler to the hot tap?

Where does the pipe run? If possible, try and lag the pipework as much as possible.

A Quooker boiling water tap would solve the problem. They're brilliant too. I'll not be without one these days.

Dude is asking for a substitute to the hot water from his tank/boiler. Nothing about kettle replacements asked

This kind of thing?

If you have an unvented cylinder, a secondary return might be an option. This keeps water flowing round the system so it’s always available close to the taps:

The no-cost no-plumbing answer: turn the hot tap on 30 seconds before you need hot water.

I believe they can dispense normal hot water too.

they can. from your tank or boiler. They dispense boiling water, carbonated water and filtered water if you have the latter two attachments

You cannot use boiling water from the quooker tank and mix it with cold and get warm. It does not work like that.

Yes you can

Quooker combi will provide hot (as opposed to boiling) water

Longer answer. Your options are:

Secondary circulation - best option. This circulates hot water form yeh cylinder, minimising the 'cold' length of pipe to draw through. I'd the works are all done though, likely mega disruption

Trace heating - an electric heating cable fixed to the pipe. Marginally less disruptive than running a secondary circulation, but not much...

Decentralise - generate hot water locally, either with a point of use water heater, quooker combi, or electric instantaneous water heater

Live with it

We had similar issues. Our old kitchen tap was the furthest run from the boiler, so we used to fill up bowls for washing up in the utility room. Kitchen tap would need to be running for 30-45 seconds before getting warm...

New kitchen installed in September and we opted for a Quooker combi (7 litre tank) and it's fab. Yes you get boiling hot water instantly, but more importantly we get cold, warm and hot water instantly as well.

No more trips to the utility room to get hot water. Well worth the investment, and bonus that you can ditch the kettle.

Exactly the same situation here. It can take a minute (which feels like 5 minutes) for the hot water to flow to the kitchen sink. Plumber says it’s just the last outlet in a long system. We do have a Quooker which gets round the issue but it is frustrating.

I stand corrected. Is this new?

I don't recall seeing anything about this when I bought my quooker tap at the end of 2023

Relatively, I think about 12-18 months ago?

They also do a 'combi +' which I wasn't aware of

https://www.quooker.co.uk/quooker-combi-plus

This appears to be intended to work with a hot feed but gives instant hot water. It will feed in boiling water to the hot supply so you get instant hot, then when the hot water form your cylinder/combi boiler comes through it lets that take over

I'd never heard of them before, but an ex-colleague had a "Willis" (i think it's a generic name, not a brand) heater to provide instant hot water - quick look suggests it's basically a small tank and immersion heater.

I'm pretty sure he has a looped hot water system - if that's correct it doesn't make any obvious sense to me why it would need an additional heater.

I can recommend this brand.
