Can a wet underfloor heating system be extended

Hi It is always advisable to get the underfloor heating done at one time but if thats not possible then certainly you can extend the Under Floor Heating but it has to be pre planned before laying the pipework. The extensions pipes needs to be blanked for further extension. Special fitting are available for extending and repairing underfloor heating pipework. Regards Cozy Home Improvements Ltd

wet underfloor heating units could possibly be extended but the problem would be mainly with warranty and how you plan to allow for extension at a later date.you will need to purchase a manifold that has provision to add extra runs in the future. underfloor heating is normally plannedto the size of the room, and the size of the water runs precalculated so there are no joints to fail under the floor once it is laid.this would then allow for cover under warranty.when you decide to extend you cannot have a joint under the floor that could possibly fail,but you could have another run added to the manifold and have a single thermostatic control both those runs.this would allow for the warranties to give cover after installation as it would satisfy the no joints under the flooring rule.

The best way to do this is that you devide the area in 2 zones so the pipe work does not need to be extended because never good practice to joint the underfloor heating pipes Hope that helps Buzan plumbing

If you are are going to do this installation in two parts I would suggest all joints be accessible so the u/f heating has no joints that cannot be accessed Also install a second manifold for the other area you wish to install Regards smiffys plumbing&heating
