Duns is the natural service town for Berwickshire — a working market town surrounded by big agricultural country. The mix of Victorian stone houses around the Square, post-war estates off Castle Street and a wide rural patch reaching toward Polwarth and Greenlaw makes for a healthy spread of gas, oil and LPG work.
Full central heating systems across Duns — first-time installations, system conversions (open-vent to sealed, gravity to fully-pumped), radiator and TRV upgrades, power-flushes, magnetic filter retrofits and zoning. We design the system around your property's actual heat-loss and hot-water demand, not a generic kW rule of thumb, so the result is a quiet, balanced system that warms every room evenly rather than one hot rad and three cold ones.
Full central heating upgrades in Duns are about more than the boiler. We balance the radiators, fit TRVs on every room, add a magnetic filter, replace tired pipework where corrosion has set in and zone the system if the layout justifies it. TD11 homes with long pipe runs particularly benefit from rezoning and a proper power-flush at change-over.
Travel from our Kelso base: 30 minutes via the A6105.
Every Duns central heating upgrade includes a benchmarked commissioning record, magnetic filter and a written balancing sheet for each radiator.
Step 1
Room-by-room calculation, current radiator audit and pipework condition check.
Step 2
Itemised proposal — emitter sizes, pipework runs, zoning, controls and timeline.
Step 3
Pipework, emitters, controls and boiler tie-in. Power-flush at change-over.
Step 4
Each radiator balanced individually, controls demo'd, benchmarked record left on site.
Yes — we design and zone larger heating systems properly, including zoned weather compensation and underfloor heating where it makes sense.
Yes — Polwarth, Greenlaw, Gavinton, Allanton and the wider TD11 patch are part of our normal Duns round, with most farm and steading work booked in within the week.
A boiler swap is the boiler only. A central heating upgrade also addresses radiators, pipework, controls and balancing — useful when the existing system is sluggish, noisy or unevenly heated rather than just old.
If the system is more than ~10 years old or you're upgrading the boiler on an unflushed system, yes — manufacturer warranties typically require it. We test the system water and recommend honestly rather than blanket-selling flushes.
Yes — most homes benefit from at least two zones (e.g. upstairs / downstairs or living / sleeping). We cost zoning alongside the boiler and controls so you see the full picture before committing.
