Hello! I'm rennovating a house that I intend to rent out. Essentially
I have two bathrooms, each of which is going to have a bath with
shower over. I want to be able to run both showers at once (as there
will be six people in the house), and my plumber thinks the only way
to do this is with electric showers. Does anyone know if there's a way
to run two showers (with thermostatic mixer valves) at the same time
off the one combi boiler I'll be putting in, or is my plumber right?


It is certainly possible to get the same sort of flow at the same
temperatures as an electric shower from a combi.

There is another advantage of fitting an electric shower in this
scenario... as you have no immersion heater, consider what happens if
your combi breaks down: your 6 tenants are without any form of central
heating or (more importantly) hot water. You'll be frantically trying
to get an emergency plumber to fix it; and what happens if he can't get
the parts for a couple of days? Answer - you'll be footing the bill
for alternative accomodation for your tenants.

Having an electric shower, completely independent of the combi, gives
you a bit of flexibility at least if the worst happens: at least the
tenants can still wash!
