What heating engineers do
Heating engineers install, service and repair the systems that keep your home warm — gas and oil boilers, radiators, controls and increasingly heat pumps. Gas work is legally restricted in Ireland: it must be carried out by a Registered Gas Installer (RGI). With SEAI grants driving a wave of retrofits, many heating engineers now also fit heat pumps and upgrade controls for better efficiency.
- Boiler replacement and installation (gas & oil)
- Annual boiler servicing and repair
- Heat-pump installation (air-to-water)
- Radiator upgrades and heating controls
- Power-flushing heating systems
- Gas cooker and fire installation
- Zoning and smart-thermostat upgrades
What to check before hiring a heating engineer
- RGI (Registered Gas Installer)Legally required for all gas work in the Republic — never let an unregistered person touch gas. NI equivalent is Gas Safe.
- OFTECThe standard for oil-fired boiler work.
- SEAI registrationRequired for grant-supported heat-pump and heating-upgrade works.
- For any gas work, check the RGI card — it's a legal requirement and your safety depends on it.
- Service your boiler annually; it protects the warranty and catches problems early.
- For heat pumps, use an SEAI-registered installer so you don't lose the grant.
