I installed two 900watt infrared mirrorstone picture panels in my lounge and dining room last winter and have to say they did a superb job, from 20th December until they went off totally it cost me less than £80 to run them, this is a house with people home all day. Can I ask how are your panels different to the ones I am using?
At 3:30 you say "that's true with a HP" but when the grid goes fully renewable, then the electric running and CO2 impact of IR will be same. BUT HP leak gas making them more of an issue. Your HP is 3 time more efficient BUT, it's to be on 3 times longer to reach thermal comfort where's IR is 'heat on demand' so it balance out especially when your opening and closing doors. so HP is efficient heating on paper but IR is smart heating in reality. Your giving HP too much credit.
