combi boiler with emmersion heater help please

happyhero

Hi I used to be a building services engineer so had training in many fields but not expert in all (had some plumbing training and quite at home with doing my own) but I now work as a fully qualified electrician.

In the house (a friends house) I am working now they have a fairly new Worcestor Bosch wall mounted boiler and while I was working on the electrics I found this supply with a switch that had been taped off. Tracing the cable I found that it fed an emersion heater in the bathroom and obviously they no longer use it if it has been taped off for ages. The supply is messy and I want to remove the cables and burnt out switch but the emersion heater still has plumbing to it. I explained to them how some people keep their emersion heater in case their boiler ever fails but where I am lost is do you do this with combi boilers too, or is it a no no with combi's due to altered plumbing etc?

Also they no longer wants the emersion if it can be removed but what is the situation with the plumbing?

Would the water still be going through the emersion pipework or can they be capped off at every joint back at a suitable point? Basically they would like the cupboard space. When I had my combi fitted ages ago I had all my tanks and emersion removed and it was great as it gave me all this space back.

Any help appreciated.

what criteria have you used to come to the conclusion that it is a combination boiler you are dealing with?
