were to site a combi

[desrob]

the old bbu is coming out and a combi going in, the problems is the customer wants it site'd in the kichen and the central heating pipe work,manifold on each floor type is at the other end of house solid floor and a step up in level, the obvious place is at the cylinder but getting the gas to there will be a nightmare, i know it's one of those questions really difficult to answer with out seeing the job, it's an old system no boiler inter lock just a pump that kicks in when heat is called for, any thoughts on this, i have a feeling it's going to be the type of job were you just plod on and see where you end up
