Boiler Replacement in Co. Galway
14 businesses offering boiler replacement across Co. Galway.
Most boilers are replaced for one of three reasons: repeated breakdowns on a unit that is past economic repair, parts that are no longer manufactured, or a move away from an ageing oil or solid fuel system. A replacement is a bigger job than it first appears, because the new appliance has to suit the house rather than simply match whatever was there before.
The main decisions are fuel and boiler type. A combi draws hot water on demand and removes the cylinder, which suits smaller homes but struggles where two showers run at once; a system boiler keeps a cylinder and copes better with higher demand. A like-for-like swap is the quickest option, but changing type means pipework, and possibly a flue route and gas supply, all have to be reassessed. A power flush of the existing system is often specified so that debris from old pipework does not damage the new heat exchanger.
Natural gas and LPG installation must be carried out by an installer on the Register of Gas Installers of Ireland (RGI), which is a legal requirement rather than a voluntary accreditation; oil installations are usually OFTEC registered. If you are replacing a boiler as part of a wider upgrade, it is worth checking what SEAI currently supports before committing, since grant support is directed at heat pumps and fabric upgrades rather than at replacing one fossil fuel boiler with another.

Common questions
How long does a boiler replacement take?
A straight swap of the same boiler type in the same position is commonly a one-day job. Changing from a system boiler to a combi, relocating the boiler, or altering the flue route adds pipework and typically extends the job across two days or more.
Combi or system boiler?
A combi heats water on demand and frees up the space taken by a cylinder, which suits smaller homes with one bathroom. A system boiler with a cylinder holds a reserve of hot water and handles simultaneous demand better, so it usually suits larger households. The right answer depends on how many bathrooms are used at once, not on which is newer.
Does the installer have to be registered?
For natural gas and LPG, yes. Working on gas installations in Ireland without RGI registration is illegal, and you can check any installer against the public register before booking. Oil boilers fall outside RGI, where OFTEC registration is the usual equivalent.
Is a grant available for a new boiler?
SEAI grant support is aimed at heat pumps, insulation and other fabric upgrades rather than at replacing a boiler with another fossil fuel boiler. If you are considering a heat pump instead, a technical assessment and an installer from the SEAI registered list are required. Confirm current terms with SEAI directly, as they are revised periodically.
