3 phase installation for power shower

[UKMeterman]

Hi.
So get the cylinder changed for an unvented modern one, they have very little heat loss, and then replumb to have a mains pressure shower. The cylinder is then heated over a longer period with a 3Kw heater.

sorry im pretty new and rubbish with heating systems... i need more details...
is that mean i can get rid of the water storage in my loft ?
what do you mean by replumbing?
thanks

Hi,
Yes the tank in the loft can go, you will need a new mixer valve, and if you buy the right cylinder you have the option in the future to have solar to heat the hot water directly.

looks like the safest and better option eould be a thermal store? would you agree? but looks like there will be a limited amount of hot water available?
is there any other type of boiler that can deliver unlimited hot water at main pressure?

It takes a lot of energy to heat water, look up the specific heat capacity of water. You do not have enough energy avaliable at your location to heat water at the rate you want on demand. The unvented hot water cylinder I have suggested are now becomeing common in the UK and have been used for many years on the continent. If you do go down the route of the thermal store you need somewhere to put the thermal store and due to the accessories such as the plate heat exchanger you may find it too big.

I'm very worried by this thread.

Just close you’re eyes and think of England.

If this thread worries you there’s even better if you look for them!

i understand, but i can see some boilers 15kW single phase, surely they can deliver around 10 liters/minutes hot water with heat on demand ? that's all i want
as i understand, a thermal store has hot water in it, and the hot water delivered is only the main cold running through inside the thermal and taking the heat of the warmed water inside.
even if there a combi (that would leave me the option to install radiators one day if i need to)

thanks

Your Electrics can't supply 15KW if you want anything else connected at the same time, 15KW from GAS is easy to do. If you want stored hot water, or a thermal store have a chat with Albion Cylinders Albion Water Heaters they do Unvented cylinders and thermal stores.

I get the feeling that someone is taking the ............

He is now talking about Gas when earlier he didn't have any. Everything you suggest he just come up with another impractical suggestion. We are just too helpful !!!
