We have a condensing boiler so no water tank in the loft. Is it possible to have a power shower that works of mains cold water feed only? If so do you know what sort I need and where to get one?

Yes it is possible to run a power shower of the mains cold water feed .Instantaneous showers get their power from a separate radial circuit.As most models of shower have a loading of either 6 or 7kW they can be supplied safely by a circuit that has a current rating of 30A and is run in 6mm two-core and earth cable.If it is a 8kW shower provided the radial circuit originates at either a cartidge fuse or MCB-which both have the effect of uprating the circuit by one third- then a 30A circuit will be adequate.B&Q Home Base wot one 6 or 7kW.

A confusing question and confusing answers so far!!
'Power shower' unfortunately means different things to different people! to me, and most pros it means a pump to boost the shower pressure to a mixer valve this can be a concealed twin impeller pumpbelow the bath or hidden away, or it could be a self contained mixer/pump like a Mira Event or Extreme
Neither of the above are suitable for use with a condensing boiler, you will already have hot and cold water at mains pressure, just fit a mixer suitable for unbalanced supplies.
An electric shower is sometimes mistakenly called a power shower, it works on cold only mains water pressure and has electric elements which heat the water 'instantly'. You could fit this to a cold mains supply, but would be much better with a mixer, either Mira Excel or Hansgrohe

This is the way all electrical showers work. Straight from the cold rising main. The water is heated as it goes through the shower, and comes out hot.
A power shower will have a pump in the circuit prior to the shower to boost the mains pressure from the rising main and at the shower itself.
If you have a normal instantaneous shower such as a Mira over the bath, the all you need is a cold water connection from the rising main, and a suitable electrical supply.
A true 'power-shower' will need a pump to be installed in your loft-space, and is a more complex arrangement. Once again, Mira will be able to supply all the parts you would need.

Confused...........if you want to fit a shower supplied only by mains cold water, this will have to be an electric shower. Electric showers have a small heating can iside with elements which heat the cold water as it passes through, but are not generally considered to be 'power showers'. Power showers come in 2 versions........one is a mixer valve & separate pump thru which the hot & cold water is delivered, the other is refered to an 'all in one' power shower (which can often look like the electric shower) and this version has a small pump built into the cabinet to deliver the hot & cold water. It depends on what you want from the shower...........if you need instant hot water for as long as you like then go for the electric shower although the shower from one of these can be pretty poor compared with the pumped versions. Both versions of the pumped showers will give a good drenching shower but rely on you having stored hot & cold water to supply it. Condensing boilers & combination boilers supply pressurised hot & cold water & there are showers made to operate from these boilers & generally the performance is on a par with the mixer valve/pump version

You can either use an electric shower that heats the water as it passes through ( in UK you will need an electricity supply of 30 - 45 amps depending on the shower. The alternative is to use a mixer shower that is compatable with a combi ( most are). It would be cheaper to run and give a much better shower.

An electric shower requires a lot of "juice" as it heats the water instantly, therefore it has to have a massive cable of 10 m.m.on a dedicated supply right back to the meter box. This can involve tremendous disruption to a household trying to get the "runs" A power shower gets its hot water from the existing stored cylinder, and only requires a small quantity of "juice" to make it operate the pump, this can be taken off the existing ring circuit of the house., and can operate through the existing shower set-up..

Yes you can connect straight on to the mains water but you must fit a non return valve.
An electric shower is what you need but it will have to be wired directly in to a 30amp fuse in your fuse board
I suggest you contact both Plumber and Electrician

no you can't legally pump direct off the mains you would have to connect to a water tank using the pump other wise you will have to get a electric shower to come off mains using it's own bar rating

NO......... You are not allowed to pump the mains
Buy a shower that works off your type of boiler, if in UK try B & Q
It will be at mains pressure, but not greater .
