    Great product, so far, and excellent service. I ordered over the phone about 11am and it was delivered the next day in Melbourne at about 12. Thank you

    Thermogroup Thermonet Undertile Heating Kit

    The installation process was relatively simple, and the included thermostat allows for easy temperature control. I appreciate the energy efficiency of this heating system, as well as the added comfort it brings to my home. Overall, I'm extremely satisfied with my purchase from Wellsons and would highly recommend it to anyone considering underfloor heating for their home renovation project."
