Can Underfloor Heating Systems Be Connected in Series?


No. Electric underfloor heating systems should not be connected in series. Instead, each heating mat or cable must be wired in parallel to ensure the system operates safely and delivers the correct heating output.

connect two mats to one thermostat

Please note, if your heaters exceed 16 amps then they need to be wired via a relay/contactor as our range or Warmup thermostats can only have up to 16 amps wired directly into them.
