A properly working heating system isn't a luxury in Northern Ireland — it's a necessity. Mr. Water provides comprehensive heating services for homes and businesses, from boiler repairs and radiator fitting to full central heating system installations. Based in Glenavy, we serve the whole NI area.

The Problem

Heating problems tend to show up at the worst times — the first cold snap of autumn, a frosty morning, or the middle of a cold spell. Radiators that won't heat up, boilers that keep cutting out, and uneven heating across the house are all signs your system needs professional attention. Leaving heating issues untreated reduces efficiency, increases fuel bills, and risks a full breakdown when you need it most.

  • Boiler repairs and diagnostics
  • Radiator installation and replacement
  • Central heating system design and installation
  • Heating system flushing (powerflush)
  • Thermostatic radiator valve (TRV) fitting
