We had a sparky in recently to install a new consumer unit for us, I was chatting to him about showers and he reckons if we got a combi boiler and had it installed upstairs in the airing cupboard, we'd get a much stronger flow rate to the electric shower.
Is this true or is he talking bollocks? Because I thought electric showers only run off cold water feeds, so the feed to it wouldn't need to go through the boiler would it?

He claims his shower flow rate is more powerful since he's had this done at his house.

Do you have a condensing boiler just now?

Seems daft to me.
Surely the only way to increase flow is to run larger dia pipe from your water inlet to shower?

If you had a combi you wouldn't need an electric shower.

With a combi you will have pressure problems if you were running a bath and a thermostatic shower in another room due to there being no cylinder.

How can I find out what sort of boiler I have? I know it's definitely not a combi boiler... 
It looks pretty old, I'd say at least 20 years old.
John why would I not need an electric shower? (not being funny, am genuinely curious as I don't know that much about showers/plumbing etc. apart from basic things like changing/adding valves!)

Combi's can normally do mains pressure hot water so you just get a mixer shower.

combi boiler will not run through an electric shower or have a pump to increase flow rate to a shower.
mains pressure only!
if you have an old cylinder maybe he meant to put it on the floor above the bathroom to increase head of water... which means hes prob still talking crap

Ive always found electric showers to be absolute shite, have one now and its rubbish.
Old house i fitted a mixer shower off the mains hot water from the combi boiler and the pressure was superb. Will be doing the same again when we re-do our bathroom soon.

i have a pump system which is great for 2 showers but if a third person needs a shower there is no hot water left because to pump has drained the hot water cyclinder...
whats the presure like from a combi boiler?

the same as the mains, no good if you are going to have 3 people having showers at the same time, you need an unvented hot water system for that

So if we have a combi boiler fitted in place of where the tank is upstairs, it sounds like the pressure won't be any better for the electric shower?
I forgot to mention, the bath tub is actually a jacuzzi bath tub (this was fitted by the previous owners!). Will this affect anything in my plans for wanting a stronger shower?
