economy 7 water heater

[davey4321]

Hi Everyone,

I have an apartment, which has economy 7 storage heater and water heating via a storage tank(with combined header tank) and immersion heaters. My problem surrounds the water heater the water supplied from the tank is very low in pressure (i suspect fro a build up of limescale) also it is very rare that I need to heat a full tank of water as water for bathing is via an electric shower.

Given the low pressure of water supplied and the age of the tank, and the possibility it may need to be replaced(it seem this may be costly) soon does anyone know of a more modern cost effective way of supplying wate to the kitchen sink and also bathroom sink.I have seen on ebay undersink water heaters eg EW10 Redring 10L Unvented Water Storage Heater. for instance would such a system be more effective.

Thanks

Your problem is that there is not enough head of water to give you any pressure.

Any solution would be to either use a cold water feed and instant heater (as you have described)
or
Install a pump on the hot water outlet from the tank
or
ditch the combi tank and install a Megaflo or other pressurised system with immersions to heat the water.

This is rather more a plumbing than an electrical issue - unless some bright spark comes up with other ideas I suggest you ask on Plumbers forum.
