Mid terrace house built in the 60's, the floor is stripped down to concrete. We would like to install underfloor heating... Have heard of these underfloor heating systems as a dry construction system. But essentially we have the following question:
— What is the structure of the underlayment? Pouring – insulation – underfloor heating – screed – floor covering?
— Why does the underfloor heating have to be under the screed? Will it also work over the screed?
— Is there anything else important to consider?
