I came across this gentleman at the ploughing championships in Sept past. I thought his product was excellent & sorted a lot of problems for boiler stove installations. There’s no wiring & easy to retrofit or install on new builds. I have a Reginald stove in my own house which has 27 rads & most of these are doubles. The system is zoned so I can have the stove for upstairs or downstairs. If the two zones were open all the rads were lukewarm & a few with no heat at all. I installed the Heat Hero a few weeks ago & I can honestly say it’s unreal.
No prob heating all 27 rads & loads of hot water.
