New boiler?

[dwnixon]

So I'm in need of a new boiler, got an old back boiler behind an old gas fire that I NEED replacing. It's completely inefficient and costing us a bomb. We're in a 3 bedroom semi built in the 1930s and I'm just not sure what to go for in terms of a replacement. I've got a quality plumber on board but can't decide between:
1. Combi
2. System
3. Regular

Any advice? Which would you go for? My main concern is that with a combi I'll have issues with the pressure changing when multiple taps are on but is it more efficient? Which costs the least to run?[/b]

Your quality plumber should be able to explain the pros and cons of each, give you costings and his suggestions.

If you have one bathroom just go with the combi. Good plumber should be able to explain
