Installs
An install, junction by junction.
Junction 01 · Load calc
Load calculation, not a window quote
We measure every room, check your water main's flow rate, and size the boiler on paper. Takes an hour; saves you from an oversized boiler that short-cycles for a decade.
Junction 02 · Quote
Fixed quote with the working shown
Model options at two or three price points, the load-calc numbers attached, and the warranty terms in plain English. Valid 60 days, no pressure calls.
Junction 03 · Install day
Usually done in a day
Old boiler out, system flushed, new boiler on the wall, filter fitted, controls paired, and the heating back on before we pack the van.
Junction 04 · Handover
Registered, certified, explained
Warranty registered with the manufacturer, Building Regs notified, Benchmark book completed, and ten minutes showing you the controls until you're bored of us.

Readings from warm houses.

"Three firms quoted off a photo of the old boiler. Copperline measured every room and recommended a smaller, cheaper boiler than the others. It's been faultless for two winters."

"The back bedrooms were always freezing. A power flush and proper balancing sorted what two 'new radiator' quotes wouldn't have. Showed me the sludge in a jar, grim and brilliant."
Simone R.Nether Edge · Power flushBREAKDOWNRESTORED ✓
"Boiler died the day after Christmas. On the Flame plan, so we jumped the line, technician out same afternoon with the right part on the truck. Worth every penny of $24 a month."

Cold house? Let's fix the math.
