We have a Heat Design Insert Boiler Stove installed along with the Heat Hero in May 2019. We’ve been using it through the winter and I have to say it is a game changer, it brings the type of heat to your rads that I’ve only seen oil boilers accomplish. Instead of 5/6 rads lukewarm we now have 10+ with great heat. Very helpful through the whole process and I would highly recommend the Heat Hero system.
