Underfloor Heating Upgrade
Legacy 20-year-old thermostats like the obsolete Siemens RDE20.1 degrade over time, leading to inaccurate temperature calibration and inefficient heating bills. Upgrade seamlessly to a modern digital unit installed by Sparky G.
Two decades of continuous operation cause mechanical switches to stick and sensors to drift, leaving your floor heating running longer than necessary.
The new battery-operated Siemens controller provides precise customized heating scheduling, and immediate energy cost reductions.
Don’t wait in the cold – if your underfloor heating isn’t working or your controller has failed, contact Sparky G Limited for a same-day replacement Service.
