Johnson and Starley Warm air heater
Hi I am after some information about replacing my warm air heating with a combination boiler. I have a top floor flat (2nd floor) and has concrete floors I have had a plumber out who says that he has to chase the floor then run the pipes in conduit so the concrete don't eat away at the copper pipes. My main concern is that the boiler would have to go in the same place as the warm air heater so would it be ok to use the same place were the original flue went, this goes straight up out the roof.

The warm air unit is probably flued to a ridge tile vent. There are some boilers that can utilise a similar arangement; however it is normal to use a purpose designed vertical flue kit. Ideally the heating pipework should be laid in covered ducts within the floor screed to allow future maintenance/inspection.
You may require permission from the freeholder when installing the new flue terminal or pipework through the walls/roof (as you don't own them).
Also check under your lease you are permitted to install a wet central heating system.

I would be more worried about damaging the floors. I would not like to hear that your floor has collapsed!
Sometimes there is a weak mix topping which can be used to contain pipes and cables but in most cases the floor should not be disturbed for structural reasons.
Be aware you will need a condensate drain connection for the new boiler.

Any reason not to fit a Part L compliant WAU. Look up the J&S web site and the Economaire units. It would be a simple change and may not have to renew all the flue and not cut the floor. If not do you have access to a roof space above your property to drop feed to rads from a combi boiler.

Still mildly on topic, after quite a few old people living in certain housing round here that is Johnton and Starky heated I decided to take myself off the Hull (the UK capital of warm air heating) for the training and qualification.
Of course I haven't had a bloomin call about it ever since, but I suppose I have 5 years to claw back the £320 (well £770 if you add in opportunity cost)
