I am looking at heating a small summer house and need hot water for taps and shower.

Anyone recommend a small electric combi?

Or do i go Electric emersion heater in a storage tank and electric radiator? Will that be cheaper?

How long will the cable be, from the meter to your outhouse?

And what large electrical loads does your main house have? Electric heaters? Electric shower? Electric cooker? Tumble drier?

You might do better to buy a smallmultifuel stove and shovel five-pound notes into it.
 
Heating with electricity is an expensive game. Plus the need for a beefy cable from consumer unit to summer house for any form of instant electric heater.
If you really want a shower out there, cylinder and immersion heater will be the better option for hot water, convector heater for space heating and insulate the hell out of the rooms

Thankyou kindly here for your advice most appreciated.
 
A Quooker is basically a vacuum flask of near-boiling water that's kept hot - it doesn't heat the water instantly.
If you use all of the stored boiling water, you will have to wait until it has heated more.

Thanks, I hadn't realised.
That's really interesting, and not something that's featured on their advertising bumf!
Especially when they have pictures of pans being filled!

You're looking at 10kw for an acceptable shower (won't be good but it'll be OK), so 40A. If you've already got an electric shower in the house you'll be getting near capacity, if you haven't then yes it'll work but beefy cable up the garden again.
