Central Heating in Stevenage

The New Town estates were built to a pattern, so once you know one home's pipework layout, you've a good idea what the next one holds. Heating systems vary massively across Stevenage, and the age of the property tells you a lot about what you're likely to find. The older homes in Shephall and the town centre often have ageing radiators that have been on the same circuit for decades — undersized for the rooms they're trying to heat, clogged with sludge, and connected to pipework that's seen better days. Some still have gravity-fed systems with a header tank in the loft, which limits what you can do without upgrading the boiler and pipework together.

The Old Town high street keeps the town's older, pre-New-Town housing, where pipework has been layered up over many decades. The newer estates on Great Ashby and Pin Green have modern sealed systems with pressurised circuits, but they're not immune to problems either. New systems sometimes need balancing when certain rooms heat faster than others. And even on a modern sealed system, the hard water in this area accelerates limescale buildup inside the heat exchanger and pipework, gradually reducing efficiency.

From the post-war maisonettes to the tower blocks and modern builds at Great Ashby, each era of the town plumbs in its own way. A power flush makes a remarkable difference to an underperforming system — clearing the sludge that causes cold spots, banging pipes, and uneven heating. For homes that need more heat output, additional radiators are installed, existing ones upgraded, or underfloor heating laid in extensions and ground-floor renovations. Smart thermostats are also wired in to give you proper control over when and where your heating runs. Gas Safe registered engineers, fixed-price quotes.

Radiator installation in Stevenage

Radiator Installation

New radiators added to existing circuits or installed as part of a new system. Radiators are sized to the room using BTU calculations so you get the right heat output — not just whatever fits the wall space.

Radiator repair in Stevenage

Radiator Repair

Leaking valves, corroded connections, and cold spots. Individual radiators are repaired or replaced, faulty thermostatic valves swapped, and systems bled where air is trapped inside.

Underfloor heating in Stevenage

Underfloor Heating

Water-fed systems piped from your boiler or electric mat systems wired independently. Ideal for extensions, kitchen-diners, bathrooms, and new builds where you want even heat without wall-mounted radiators.

Power flushing in Stevenage

Power Flushing

High-flow chemical flushing that clears sludge, rust, and limescale from every radiator and pipe in the system. Each radiator is flushed individually until the water runs clear, then inhibitor is added to protect the system long-term.

Smart thermostat in Stevenage

Smart Thermostats

Hive, Nest, Tado, Drayton Wiser — wired in, connected to your boiler, with the app set up and tested before your engineer leaves. Smart scheduling and geofencing typically save 10–15% on heating bills.

System design in Stevenage

System Design

Full heating system design for new builds, extensions, and whole-house upgrades. Heat loss is calculated, radiators sized, pipe routes planned, and the right boiler output specified so the system works as a whole — not a collection of parts.

Heating Questions

It depends on the size, type, and whether it's being added to an existing system or replacing one. See our pricing for current rates.
A power flush pushes a high-flow chemical solution through your entire heating system to remove sludge, rust, and limescale. You'll likely need one if your radiators have cold spots, your boiler makes banging noises, or some rooms heat unevenly. It typically transforms an underperforming system.
4–6 hours for a typical home with 8–12 radiators. Each radiator is flushed individually until the water runs clean, then a corrosion inhibitor is added to protect the system going forward.
Yes — the existing heating circuit can be extended into extensions, conservatories, loft conversions, and garage conversions. Your engineer checks the boiler has enough capacity to handle the additional demand and recommends an upgrade if it doesn't.
For new builds, extensions, and ground-floor renovations, absolutely. It distributes heat evenly, frees up wall space, and runs at lower temperatures than radiators — so it's cheaper to run long-term. Retrofit is possible but more involved, especially on upper floors.
Yes — Hive, Nest, Tado, and other smart thermostats. They're wired in, connected to your boiler, and the app is tested before your engineer leaves. A smart thermostat typically saves 10–15% on heating bills through better scheduling and geofencing.
Cold spots at the bottom of a radiator usually mean sludge has settled inside. This is iron oxide buildup from corroding pipes and radiators. A power flush clears it out. If it's just one radiator, removing and flushing it individually may be enough.
Yes — Bedwell, Shephall, Broadwater, Datchworth, Graveley, Weston, and all the villages around Stevenage.
