Chalk and cheese...
Before Fezzasus heater fitted - feet like blocks of ice, even with thermal socks on.
After Fezzasus heater fitted - warm as toast on half heat.
Many thanks Tom.
Good to hear. Mine is pumping out lots of air, but just warmish stuff. Talked to fezzasus and had a different rad in it to the usual one supplied. So hopefully, once that's done, get a toastier feeling
