Emitter upgrade
Radiator replacement and balancing in Bath
A single-panel radiator sized in 1985 to a boiler-flow temperature of 82°C is not the right emitter for a modern condensing boiler at 55°C. Upgrading radiators, then balancing them properly, transforms system performance.
For: Bath homeowners with cold rooms or old radiators
Balancing is where the magic happens
New radiators without balancing will still leave the far bedroom cold. We use a differential thermometer or clamp meter to set the correct flow through each lockshield — no more guesswork.

Frequently asked
- How many radiators can you do in a day?
- 5–8 for a straight swap. Full re-balance and TRV replacement adds another half-day.
- Are vertical radiators OK?
- Yes — as long as they're sized on watt output, not just aesthetics. We calculate before quoting.
- Do I need to redecorate?
- Not usually — we cover floors and get radiators off cleanly. Some old plaster reveals where the old rad sat and needs light touch-up.
