Replacing a non-condensing boiler

Hi, I have an old (c. 12 years) non-condensing boiler. It works ok but I know it's very inefficient compared to modern boilers and would prefer to get it replaced before it dies on me.

Am I right in thinking it would have to be replaced with a condensing boiler (i.e. it cannot be replaced with another non-condensing one, like-for-like)?

If so, are there any exceptions? Reason I ask is that the boiler is on the back wall of a top-floor flat, away from any drainage pipes, and without scaffolding going up I don't see how a gas engineer could fit the condensate pipe needed for a condensing boiler.

It is law that all new boilers are condensing so yes it will have to be a condensing type.
There are several ways to route the condensate so the height/elevation etc should not be a problem for a professional.
These sort of problems demonstrate our ability - don't worry your engineer will deal with it.

Hi there,we normally run the condense in to a kitchen waste if an outside drain isn't accessible,hope this helps Paul

The condensing pipe can run inside and be fitted to your wash basin/ soil stack etc.

A condensing boiler will still need to be fitted. Unfortunately regs say there is always a way to do a job even if it means relocating the boiler or maybr using a pump.

Hi, previous responses all correct advice but if all else fails scaffolding will have to be provided - more cost but oly once to do.

ok so there are exceptions to this rule and there is an exception to fitting a condensing boiler, but here you are talking about money and the laws that be will not nod their head to save you cash.. ok you are able to fit boilers from the inside if your a good experianced engineer and the condensate pipe is able to be fitted internally. where theres a will theres a way..
