Central heating that heats every room, evenly.
From a single new radiator to a full system redesign, Stewart plans, installs and commissions central heating that actually works — properly balanced, correctly sized and quietly efficient.
Full system design
Heat-loss calc, radiator sizing and pipework layout.
Radiator upgrades
Modern low-water-content rads, vertical designer options.
Pipework & valves
Copper, plastic, TRVs and lockshields properly balanced.
System commissioning
Flushed, dosed with inhibitor, filter fitted.
Common jobs
- Moving or adding a radiator (e.g. after an extension or loft conversion)
- Swapping tired panel radiators for modern efficient models
- Upgrading from a gravity-fed system to a fully pumped sealed system
- Diagnosing "one radiator won't heat" or "upstairs cold" problems
- Fitting MagnaClean and Adey filters to protect the boiler
Every system is left properly balanced with correct flow temperatures and a written commissioning record.
