Electric, mixer etc.

More than likely an electric.

Because the combi boiler is capable of supplying hot water to the shower so why bother heating up cold water with expensive electricity when it's already getting heated up by the boiler. But it depends on your house and how you use the water as to whether or not a mixer shower is feasible.

[quote author=billythekid  link=1107344942/0#9 date=1107567419]It's not a must have thing, its a matter of personal taste. Like you correctly say you can install a leccy shower if you want to. Thing is that your combi is putting out hot water at mains pressure so your hot and cold supplies will be at the same pressure, ideal for a mixer shower. A little more work on the plumbing side, but no electrical.  You need to make sure your combi can supply the mixer shower you choose(if you choose a mixer) with the right volume of water.  Personally, if I took out a leccy shower, a leccy shower would go back in, the wiring is there already, and the plumbing would only need slight alteration to fit new shower. A better idea might be to get a power shower, hot and cold (pumped) supply, loooooooovely

Cant fit a pump with a combican, nor on the mains to an electric shower.

personally I would keep the electric shower, at least it will still work when the can breaks down.

Didn't disappoint you then   anyone would think I don't like the cans  

Don't all breakdown   maybe not But I would wager 90% need parts replacement in the first 3 years  

You cant just cap off cold mains pipe, tee has to be removed so as not to leave a dead leg, nasty liccle germys breed in the still water, plus if you have a combi dead legs cause problems with the boiler clicking on and off when opening other cold taps in the property due to air in the end of the dead leg.
