High-power shower, tank or heater?

[markdw77]

Dear all , thanks for reading.
I am planning a wet room on the ground floor of my property. I have a 12" shower rose, which will need a hell of a lot of water running through it to give a good powerfull shower. I seriously doubt my combi boilder or water pressure are up to this.

So I am after some advice on what to do. I think i will need a pump, but would I be best to get a hot waqter tank with immersion heater, or an inline water heater to heat the water as it passes?

I do not have a hot water tank at the momnet, but there is space above my planned wetroom, about 3ft high, and the same size as the wetroom below (approx 6 x 4)

Any help, tips or links would be much appreciated!

Many thanks, Mark

I don't believe an inline water heater would be very efficient. Might want to try the tank idea for your situation in regards to what you are doing.

Heating the water I think is the easy problem. I think how to get tons of water will be the bigger problem. You may need a boost pump and/or large diameter water lines. Another fun problem I've seen is the flow capacity of modern faucets. Many modern units have small internal passages and don't flow much water, they are designed to flow 2.5 gal/minute. Olde fashioned faucets can really let some water go!
