Hi.

I have a house with 2 boilers.

There is a system boiler in the Cellar which provides hot water to the entire house via a Storage Tank, and central heating to the mail living area and 2 bedrooms.

Another boiler in the attic provides central heating only to 4 bedrooms, landing, and bathroom.

Both boilers are about 35 years old.

The attic boiler is a Glow Worm 45/60, and is leaking carbon monoxide into the room. It needs replacing, but I want to relocate it from a bedroom into a storage cupboard. The storage cupboard has a partial sloped ceiling so the fitting space is fairly small. Because the roof is slate, I would like to not disturb it and vent through the back of the boiler.

There is also a shower room directly below the storage cupboard, which presently holds an electric shower with cold water feed. I would like to change this in the future and install a thermostatic shower from the new boiler, so I believe a combi boiler is best for the job.

An installer has recommended a Glow Worm Flexicom 24CX, and has promoted the 10 year warranty. However after reading the reviews on this forum i am not sure this is a reliable boiler. The benefit is the direct rear venting flue.

Can I please have some opinions? Suggestions for a different boiler? or confirmation that the flexicom is the most suited to this type of environment.

Thanks.
 
Fitted 17 flexicoms last year, no problems to date. Been fitting them since 2009 with only 1 that had a faulty gas valve on from new.

Did your installer take any pressure and flow readings to come to the opinion that a combi is really the best solution?
 
I've fitted lots of flexicoms. Not had any problems apart from make sure the system is clean and a magnetic filter fitted. The guys may correct me if I'm wrong but I think the ideal logic + Combis can have a rear flue. (That would be my preferred choice)
 
If the boiler in the basement is also 35 years old, it will be very inefficient and will also need replacing soon. Unless there is a specific reason for having two boilers, why not get rid of both boilers, combine the two systems and install a new condensing boiler in the basement?
