But what to do if the existing floor construction is a screed floor and you’re limited with build-up (due ceiling height)? Indeed, JK’s system is the solution. JK’s UFH system is embedded into the existing screed floor by grinding 16 [mm] channels where the heating pipe is laid into. The floor finish, tiles, vinyl, wood, carpet or resin can be applied on top and makes it a very comfortable, efficient and affordable heating system. The total area in this house is about 130 square metre and fed with two JK stainless steel manifolds located in the hallway. The system is designed in 6 zones and can be controlled separately. This makes it possible to have different temperatures in different rooms at different times.
