Advice re: multiple showers

Hi

We are converting part of our house into a self-contained apartment. We want to put an electric shower into it, but we have one in the main house already (and are planning to put another shower, not electric, in another shower room we are constructing in the main house). In order to avoid having to give the apt a separate circuit and getting the boys from the overpriced ESB to do this, we have to come up with a plan B if we want to continue on this line. We are thinking of putting the shower that is currently in the main house into the apt and using two 'ordinary' showers in the main house instead. Is this a runner?

Any suggestions re the types of ordinary showers ... would it be possible to have two power showers or is this likely to be highly expensive in terms of water heating (and water usage, if that becomes an issue in years to come, as well as fm an environmental pov). We have to change the cylinder anyway. Any other issues we should be aware of?

Any thoughts appreciated. Tks.

If you have 2 electric showers you should have an isolator unit to ensure both showers can't operate at the same time, I got one recently for 350 euro.

The heater in the electric shower is what usses all the power.
You should be able to run a few power showers no problem.
Of course you need to mix in already heated water.
Against that the power shower will give a much better flow.

An electric shower is restriced to one cold feed, and can only heat the water so fast. whereas the power shower has double the feed a hot and cold of course there is more room for the pump as well.

A pumped shower doesn't need nearly as much energy as an electric.

Any decent electrician should be able to advise.
