Radiator Installation
— About This Service
Reliable Radiator Installation for Period Homes
Every Radiator Installation starts with a site survey and heat-loss assessment so radiators and valve types are sized correctly for each room. Our three-stage process — supply, professional fitting by Gas Safe‑registered heating engineers, then system flushing/balancing and TRV commissioning — reduces cold spots and improves flow. We install panel, column and designer radiators, replace corroded units and upgrade valves to thermostatic control. After commissioning we tidy the area, test the system and issue clear paperwork.

How It Works
Site survey & sizing
We begin with a room-by-room survey and heat-loss check to select correct radiator types, sizes and valve specification.
Supply & professional fitting
Your chosen radiators are supplied and fitted by Gas Safe‑registered heating engineers, with neat pipework and secure fixings.
Balancing, commissioning & handover
We balance the system, fit TRVs where needed, test flow and temperatures, then leave you with commissioning notes and warranty paperwork.

A Armstrong Plumbing & Heating fits single- and double-panel radiators, column and designer options to suit Victorian terraces, coastal cottages and new-build homes around New Milton, Christchurch and Lymington. We size each radiator to the room, recommend appropriate valves (lockshield, angled or straight) and offer thermostatic radiator valves (TRVs) to improve room-level control. Where systems show sludge or poor flow we advise on power flushing before replacement to protect new radiators.

Frequently Asked Questions
We carry out a heat-loss assessment at the survey: we measure room dimensions, window sizes and insulation, then pick a radiator with the correct kW output. Correct sizing avoids underperforming radiators and prevents oversized units that waste energy.
