Immersion heater services in Galway
Galway county covers a wide range of property types and fuel sources, from the dense urban environment of Galway city to highly rural areas of Connemara where mains gas is not available. The natural gas network covers Galway city and some surrounding towns, but much of Connacht remains outside the gas grid. Installers in Galway city typically focus on natural gas work, while those operating in Connemara, South Galway and the islands often need LPG certification for rural properties.
Galway city has seen rapid growth with large new residential developments alongside older Victorian and Edwardian housing stock. County Galway outside the city is largely rural with many older cottages and farmhouses that have been extended or renovated, often with mixed generations of plumbing work.

- Draining and refilling the cylinder is the slowest part of any immersion job

Hiring
How to Find a Plumber for Immersion Work in Galway
The plumbing side of immersion work in Galway is done by a plumber, with the final electrical connection to a new unit made by a registered electrician. Here is how to hire correctly.
Browse Plumbers in Galway
Browse local plumbers in the Galway plumber directory. Find plumbers near you who handle immersion elements, thermostats and timer setups, and contact them directly. No fees and no sign-up to get in touch.
Get a Clear Quote for the Work
A good quote names the element and thermostat rating, the labour to drain and refill the cylinder, and whether a timer or fresh wiring is included. Ask whether the plumber arranges the electrical connection or whether you need to book an electrician separately.
Confirm the Final Electrical Connection
The plumbing is done by a plumber, but the final electrical connection to a new immersion should be made by a registered electrician on the Safe Electric (RECI) register. For a like-for-like element swap on existing wiring, most plumbers complete the job in one visit.
Check the Element and Thermostat Rating
In hard-water areas an Incoloy element resists scale far better than a standard copper one and lasts longer. Confirm the thermostat is set to 60 to 65 degrees, hot enough to kill bacteria without wasting electricity or scalding.
Local coverage
Immersion Heaters Across Galway: Areas Covered
Galway faces the full force of Atlantic weather, with the highest rainfall in the country in the western parts of the county. Exposed pipe runs on west-facing walls are a known vulnerability, and outdoor taps and garden connections need annual winterisation.
Galway city's construction boom has driven strong demand for new-build plumbing and heating fit-outs, while the rural county generates consistent demand for boiler replacements and oil-to-heat-pump conversions under SEAI schemes.
Every area above is served by registered plumbers in the Galway plumber directory.
Common questions
Immersion Heaters in Galway: Common Questions
How much does it cost to replace an immersion element in Galway in 2026?
An immersion element replacement costs €120 to €250 in Galway, including labour and VAT. The cylinder has to be drained and refilled, which is where most of the time goes. A thermostat swap on its own is €80 to €160, and a dual immersion upgrade €300 to €550.
Why does my immersion keep tripping or stop heating in Galway?
The usual causes are a burnt-out element, a failed thermostat, or limescale that makes the element overheat and trip the switch. A Galway plumber tests the element and thermostat, and a scaled or open-circuit element is replaced rather than repaired.
Is a dual immersion worth it for a Galway home?
For larger Galway homes, and anywhere the immersion does the main water heating, a dual immersion is well worth it. The top element gives a fast boost while the bottom element heats a full tank overnight on a timer, keeping running costs down through the colder months.
Can I fit a timer for night-rate electricity in Galway?
Yes. A timer set to a night-rate or smart tariff heats the cylinder overnight on cheaper units, giving Galway homes a full tank for the morning. Timer and off-peak wiring costs €120 to €250 and is one of the quickest ways to cut hot water running costs.
Do I need an electrician as well as a plumber in Galway?
For a like-for-like element or thermostat swap on existing wiring, a Galway plumber usually completes the job. For a brand-new immersion, new circuit or timer wiring, the final electrical connection should be made by a registered electrician on the Safe Electric (RECI) register.
How long does an immersion replacement take in Galway?
An element or thermostat swap takes an hour or two once the cylinder is drained. A full new immersion, or a dual immersion and timer upgrade, is a half-day job. Draining and refilling the cylinder is the slowest part of any immersion job.
