Raise temp of cold water tank

[JohnD]

do you have a boiler? is it gas/coal/multifuel or what? is it a combi?

do you have a hot water cylinder?

He's got electic showers gravity fed from a cold water storage tank. His problem is that the lower cold water temperature in winter means that his electric showers cannot give a decent flow rate at a satisfactory temperature for him.

He hasn't actually said where they're fed from. Maybe he wants to heat the tank and then connect the shower to that, or he believes they are supllied from the tank. Hopefully he will clarify.

An electric shower supplied from a tank is unusual, as DIA said.

Sorry for the [mis]information guys Just went into the loft to check the pipework properly.

Mira 10.5kw showers - one in the ensuite, the other in the main bathroom.
Both are mains fed - I was convinced they were fed off the cwt.

Hot water cylinder in airing cupboard upstairs [same level as two showers]

Sorry for not checking properly first off.

as you have a hot water cylinder, you can run an ordinary thermostatic shower off that. You will presumably have to add new pipework.

however unless your cold water tank is very high above the showers (say, 10 metres) the flow will be poor unless you add a shower pump (the height of the cylinder is irrelevant to pressure)

on the plus side, this will give you water as hot as your cylinder, and a hugely better flow, and if you heat the water by gas, it will be about half the price per litre (but a power shower will deliver more litres per second)

if you go this way, make sure the cylinder and pipes are well lagged

Thanks for the replies.

CWT barely a metre above shower heads, so, it looks like new showers and an inline pump will be on the budget for proper winter showers.

Thanks again for your help.
