Is it feasible to relocate a combi boiler?

[redlagoon]

I'm looking for some advice about the feasibility of relocating a combi boiler.

The situation is as follows;

I'm doing a complete refurb on a 3 bed terraced house.

As well as some rewiring and skimming, my plan included replacing the old boiler and hot water tank with a modern combi. One of my original intentions was to build a rear extension which would house the new combi.

The plumber came in first to flush the system, and then do some minor pipe work relocating some rads. The rest of the CH and hot water pipes are unchanged.

Knowing my intention with the extension, the plumber extended the pipes for the main gas, water and hot water feeds leading out of the house into the garden. They are sitting outside disconnected at this time. The hole left by the original boiler has been blocked up and a new kitchen installed over it.


I'm now thinking about abandoning the extension for now. The most significant barrier to this is the CH and hot water feeds.

How realistic is it to move the boiler location elsewhere? Or what options, if any, do i have?

He may have extended the gas pipe but if you are changing to a combi you will need the entire gas carcass increased in size, especially if it is a 'standard' terraced house with the gas meter at the front and combi at the rear. It will have to be at least 28mm copper most of the way.

You can install a combi almost anywhere as long as the flue clearances conform to regs and you have access to drains for the condensate and hopefully an outside wall for the prv discharge pipe.

How do you mean ? Do you mean you're unsure of adding length to the pipe runs ?

My combi is located at the far side of a 4.5m long utility room so I've got longer pipework than I'd ideally like, but it makes little difference to the CH or HW to be honest. You could choose a more powerful combi for a better HW flow-rate or even one with built-in HW storage to counteract the HW delay, like I did.

Hard question to answer without knowing the layout of your house ! Common locations are garage, utility room, downstairs WC, loft - pretty much anywhere in fact, providing the location requirements for a condensing combi are met, the flue location being a common issue.
