Sometimes, your boiler refuses to play. It’s not being mean. It’s just low on water pressure. Look at the pressure gauge on your boiler. It should be between 1 and 1.5 bar.
If it’s below 1, you need to re-pressurise the system. Find the two black levers underneath the boiler. They look like little tap handles. Open one, then the other.
Water will gush in. Watch the gauge climb. Stop at 1.5 bar. Close the levers tight. You’ve just performed plumbing magic. Applause is optional but welcome.
Here’s the wild truth: UK radiators are older than many of our houses. They’ve seen frost, dust, and questionable 1970s wallpaper. They have stories to tell.
Turning them on is a seasonal sport. We do it on the first chilly day of autumn. We whisper, “Right, time to wake the beast.”
