How they work
Immersion Heaters in Longford: How They Work and When to Replace
An immersion heater is an electric element inside your hot water cylinder that heats the water directly, used across Longford as the main water heater or as backup when the boiler is off. The plumbing side, draining the cylinder, fitting the new element or thermostat and refilling, is done by a plumber, while the final electrical connection to a new unit should be made by a registered electrician on the Safe Electric (RECI) register. Elements fail when they burn out or fur up with scale, and a slow-heating tank usually points to a worn element or a drifting thermostat.
The plumbers listed here cover the whole county, taking in Longford town, Granard, Edgeworthstown, Lanesborough, Ballymahon and Kenagh, so an element replacement or timer setup is never far away.
How Long Does Immersion Work Take in Longford?
An element or thermostat swap takes an hour or two once the cylinder is drained. A new immersion or a dual and timer upgrade is a half-day job.
Cut Longford Running Costs With Off-Peak Heating
Pairing an immersion with a timer lets it heat on cheaper night-rate electricity, filling the tank overnight for use the next day.
Local coverage
Immersion Heater Services Across Longford: The Areas Covered
Longford is a small midlands county with a largely rural population centred on Longford town. Natural gas network coverage in Longford is limited to the county town and a small number of other locations, with the majority of the county relying on oil and LPG for heating. The pool of RGI registered gas installers in Longford is relatively small, and homeowners in more remote parts of the county may need to source an installer from a neighbouring area.
Longford is a small Midlands county with a dispersed rural housing pattern and a single main town. The housing stock is predominantly older, with a high proportion of oil-heated bungalows and farmhouses. SEAI heat pump conversion has been gaining traction as a route to reducing oil dependency, and the county has a reasonable number of SEAI-registered contractors.
Longford is inland and flat, with minimal shelter from northerly and north-westerly winds. Cold snaps can be prolonged, and the Midlands frost record is well above the national average. Lanesborough, on the Shannon, benefits from some winter temperature moderation near the river.
Longford Town has the main concentration of plumbing contractors serving the county. Granard has some local coverage for north Longford. Ballymahon and Lanesborough in the south often draw from Longford Town or Athlone-based contractors.
Every area above is served by local plumbers in the Longford plumber directory.

How to Find a Plumber for Immersion Work in Longford
The plumbing side of immersion work in Longford 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 local plumbers in the Longford 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.
Immersion Heaters in Longford: Common Questions
How much does it cost to replace an immersion element in Longford in 2026?
An immersion element replacement costs €120 to €250 in Longford, including labour and VAT at 9%. 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 Longford?
The usual causes are a burnt-out element, a failed thermostat, or limescale that makes the element overheat and trip the switch. A Longford 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 Longford home?
For larger Longford 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 Longford?
Yes. A timer set to a night-rate or smart tariff heats the cylinder overnight on cheaper units, giving Longford 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 Longford?
For a like-for-like element or thermostat swap on existing wiring, a Longford 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 Longford?
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.
