Plumber help...Shower Advice

paradhise

I am currently having lots of work done to my house and will be getting a new bathroom installed this week.

My query is basically this, I have bought a thermostatic shower (hansgrohe raindance) and it states on the literature that it will take up to 3 bar of pressure.

I would like to convert the shower to a power shower, do I just buy a pump and will it still run off the new combi boiler or does it run off its own source?

Hope this makes sense and any help would be gfratefully appreciated.

i believe you can't run a power shower from a combi boiler, i was warned about this when we had an eco7 tank replaced with a combi.

Given you have a combi, what's the mains pressure? Most combi's will need at least 1-1.5 bar just to work. I'll look it up later but I'd guess the possible problem with the Raindance is volume not pressure.

As has been said, you can't pump the hot output from a combi.

isn't one advantage of a combi that you can run a thermostatic valve type shower straight from it? providing you have half decent mains pressure and combi.
this is what i plan to do later this year and the combi will be spec'd accordingly.

i got one of the thermostatic showers from screwfix, http://www.screwfix.com/prods/91420/Bathrooms/Showers/Mixer-Showers/Thermostatic/Thermostatic-Dual-Control-Shower-Fixed-Kit
works great and doesn't need a pump.

you can't fit a pump on a combi boiler system, it can only be piped up to the combi and hope you have enough pressure to run it.
