Instant hot water - solutions?

middling

Hi,
I'm looking for ideas about how best to have instant hot water when you turn on the tap! We are doing a major overhaul on a small cottage and plan to have oil heating and back-boiler fireplace. We'll have an immersion tank so most of the time in the winter we'll have hot water from having had the heating on.
In the summer though I'd still like to be able to have a shower/fill a sink of hot water immediately. Are there any good solutions for this or is it best just to put the immersion on timer a couple of times a day?
An electric shower would solve the shower part (but not the sink), but a) are electric showers with good pressure available these days and b) can you have a shower that is electric/immersion based depending whether you have hot water in the tank?

Thanks!!

I've seen instantaneous electric heaters being used in outhouses/ workshops.
I'd give Earthridge a ring in Maynooth, they are suppliers of Triton, and may have something for you.

A solar panel would provide hot water in the summer.

It is a simple matter to split your heating and hot water . So in summer boiler on , rads off hot water on

The Quooker boiling water tap would also be a solution to the sink issue. It is a German product licensed to a firm in Sligo as far as I know. Check out http://eil.ie/quooker.php Also there is a new Triton electric power shower on the market now.

if its instant hot water at the sink then an undercounter water heater would be worth a look,(also available in overcounter) it works on the same principle as an electric shower as it heats the water as it go thru it, good for a sink full of water though maybe not for large amounts, which as already said before the boiler would do.....
just to add i think ariston is a fairly decent version...

If you're planning to install an oil boiler, why not look into using a combi boiler? This will heat water on demand - see here to begin with:

The same boiler should do both, the heating loops can be turned off and on as needed.

Simple answer is Solar panels.

Solar is not the simple answer, although it is a very good idea. Solar hot water panels will provide a clean, cheap source of hot water, but they only work when the sun is shining. You will get your peak hot water in the evening, and on some cloudy days or days where you use a lot of hot water, you will need a separate heat source. By running a separate hot water circuit from your boiler to your hot water tank, you can set it up so that the boiler will "top up" the hot water when the sun can't.
