Installing a new heating system is one of the most significant investments you'll make in your property. Mr. Water designs and installs heating systems for homes, new builds, and commercial properties across Northern Ireland — from straightforward boiler replacements to full central heating installations from scratch.
The Problem
An old, inefficient heating system costs more to run, heats your property unevenly, and is more likely to break down. If your boiler is over 15 years old, your radiators are undersized for your rooms, or you're extending your property and need to upgrade, a new heating installation can transform your comfort and reduce your energy bills.
What This Service Includes
- Full central heating system design and installation
- Boiler installation — combi, system, and conventional
- Radiator selection, sizing, and fitting
- Underfloor heating installation

Frequently Asked Questions
A straightforward boiler swap might take a day. A full central heating installation for a typical house usually takes 3-5 days depending on the size and complexity.
It depends on your property, water demand, and existing system. Combi boilers suit smaller homes without a cylinder. System boilers work better for larger properties with multiple bathrooms. We'll recommend the right type for your situation.
Yes. Underfloor heating is increasingly popular in new builds and renovations. We install both wet (hydronic) systems connected to your boiler and can advise on whether it's suitable for your property.
