Power shower on a combi.

[Rickster123]

Evening ladies and gents,

Ive got a job coming up converting a gravity system to a combi. Reasonably straight forward job but in the bathroom theres a power shower. Looks like a b&q special, called "essentials". Are these types of shower compatible with a combi? It has a gravity hot and a gravity cold which with both be converted so that the cold is mains fed and the hot off the combi.
Any advice would be great from blues, reds and greens alike!

so when the shower is sucking in the cold, where does the hot come from?.
might work with a ballancer, but unreliable temp when another outlet is opened!.
change it for a mixer. imo/

don't think you can because of the pump in it imho

The trouble is the shower and bathroom are only about 3 year old. Didnt want to cause any extra upheaval if i didnt have to.

Hi Steve, i had a feeling that would be the answer. Had hoped it might still work. thanks for the replies tho.

No you can't

A power shower cannot run off mains

Sorry

It will leak on the seals straight away,and it is illegal to pump off the mains with a non specified device

Sheff Paul is right the o rings inside will not be able to with stand the pressure. IMO I would but them in a electric shower so that in the future if the combi breaks down they will still have washing facilities a bit like a immersion on a hot water cylinder.

just link the pipework on the pump and change everything to mains fed when you put the combi in , then sell the pump on ebay/bootsale
