Awesome, thank you.
I am not sure how to accurately measure that. It’s a very old Glow Worm boiler with just a numbers dial to set the boiler temperature. I have set it to number 4, max is 5.
Rads are hovering around 60C. I am using a cheap temp gun to get the reading off the rads.
Fair enough. You would measure the flow and return pipe work with your temp gun. You want as big a delta T as possible. So if you’ve got 60C flow, something like a 40C return would be awesome.
