The underfloor heating system can be removed and replaced with radiators, but it is up to the case to decide whether this is feasible or not. First of all, you need to consider how the underfloor heating system is installed and the layout of the pipes. If the underfloor heating system is heated by pipes under the floor, then removing the underfloor heating system may involve the removal and resurfacing of the floor, which can increase the complexity and cost of the project.
Secondly, you need to consider the installation conditions of the radiator. The radiator needs to have enough space to install and need to be connected to the plumbing of the heating system. If the ductwork of the existing underfloor heating system does not match the location of the radiators, it may be necessary to rearrange the pipes, which will also increase the complexity and cost of the project.
Finally, you also need to consider the heating effect of the radiator. There are certain differences between the floor heating system and the radiator in terms of heating effect. The floor heating system can achieve an overall uniform heating effect through floor heat dissipation; Radiators, on the other hand, are heated by air convection, which may cause local temperature differences. Therefore, changes in heating effectiveness need to be taken into account when removing the underfloor heating system and replacing it with radiators.
