I need to increase the btu for a radiator at my sons house and was thinking of putting a size 22 rather than the existing size 21. Is it just the fins that are doubled up and no other difference ? I'm trying to work out if the pipework needs to be changed as it'll be awkward as they have lvt flooring.
