Central Heating System Overhaul

Maintenance

Hi I have recently purchased a property which has an old baxi floor standing conventional boiler with a water tank in airing cupboard for a hot water. I was hoping to change the boiler and do a conversation to a combi boiler and getting rid of the water tank too. Gas engineer came round and said not a problem but there is a risk that the old radiator pipes could start leaking. His advice is, if its working then leave it for now but if any part go then you wont have a choice but to replace it. Makes sense, but I'm having new carpets laids throughout the house after decoration. It's going to get messy after having to lift all carpets again.

Another engineer has said it is possible although chances are slim and the leaks easily repairable so I shouldn't worry too much.

Pipes are running under the floor boards so in case of any leaks, we would have to lift carpets and floorboards. Sounds like a nightmare to me.

Has anyone had any experience doing a conversation on old radiators? I would change the radiators too but the cost is too much.
