Mixer shower feed through heater

[ph2010]

Hi all.Could I feed an en suite mixer shower from a loft cold tank through an inline instant electric heater and twin impeller pump.If so would the pump go before the heater or after.I would appreciate any other idea's if mine is not feasible.

Possibly, but why would you want to? Why not just have an electric shower off the mains?

Made up systems rarely work as you’d wish

I did not think enough pressure to handle on off chance 2-3 points in use at same time.

if your going to be using more than one outlet as a time start looking at the main / other things

whats your main atm lead blue etc ?

Personally with an electric shower already fitted, I can't see a reason why you cant run a mixer shower off the combi. Your heating running most of the time through winter doesn't matter, you'll only be running the shower for 10 mins at a time at most so your heating won't be off for long.
If your concerned about flow rate during multiple outlets been used, then maybe consider adding a header tank and cylinder and adding an extra zone to your heating to feed your extra shower/bathroom. Then you can have your pumped mixer.

Well it won’t so you need to look at correctly designed specced solutions. Unvented cylinder likely your best solution

If you mean mains feed pipe it is old 15mms lead pipe..

time to phone the water board and ask them whats the pressure and flow you can get
