Immersion heater services in Wicklow
Wicklow has a strong residential base driven by its position on Dublin's southern commuter corridor, with Bray, Greystones, Wicklow town, Arklow and Rathnew all having good natural gas network coverage. The county's mix of coastal towns, rural villages and the Wicklow Mountains means a varied mix of property types and fuel sources. Urban Wicklow has strong demand for natural gas boiler and appliance work, while inland and upland areas rely more on oil and solid fuel.
Wicklow's north, centred on Bray and Greystones, is densely suburban with large estates of 1980s-to-2010s housing. Moving south through Arklow and into the rural areas of west Wicklow, the housing becomes older and more varied, with many stone cottages, old farmhouses and mountain properties that have basic or outdated plumbing.

Hiring
How to Find a Plumber for Immersion Work in Wicklow
The plumbing side of immersion work in Wicklow 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 Wicklow
Browse local plumbers in the Wicklow 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 Wicklow: Areas Covered
The Wicklow Mountains create a significant weather divide. Coastal Wicklow towns are relatively mild, but inland and upland areas experience heavy snow in winter and can be cut off during serious cold snaps. Properties in mountain areas like Blessington and Roundwood need comprehensive pipe insulation.
North Wicklow benefits from proximity to Dublin and has good coverage from both local and Dublin-based contractors. Arklow and south Wicklow have a solid local trade. The more remote mountain and west Wicklow areas can see longer wait times for specialist work.
Every area above is served by registered plumbers in the Wicklow plumber directory.
Common questions
Immersion Heaters in Wicklow: Common Questions
How much does it cost to replace an immersion element in Wicklow in 2026?
An immersion element replacement costs €120 to €250 in Wicklow, 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 Wicklow?
The usual causes are a burnt-out element, a failed thermostat, or limescale that makes the element overheat and trip the switch. A Wicklow 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 Wicklow home?
For larger Wicklow 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 Wicklow?
Yes. A timer set to a night-rate or smart tariff heats the cylinder overnight on cheaper units, giving Wicklow 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 Wicklow?
For a like-for-like element or thermostat swap on existing wiring, a Wicklow 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 Wicklow?
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.
