What’s Included in a Full Water Heater Installation
Immersion heater replacement typically runs €350–€700. A full cylinder installation runs €1,400–€2,400 depending on size, system type, and existing pipework. Most jobs take three to six hours — older properties with dated pipework can run longer, and we’ll flag that before starting, not after.
Types of Water Heaters We Install
Immersion elements fail faster than they should in hard water areas like Annacotty and Bunratty — mineral buildup eats away at the element from day one. We advise on the right protection upfront rather than let you find out three years in.

most common in older Irish homes, fed from a header tank
Unvented cylinders
mains pressure, stronger flow to showers and baths

Repair, Replace, or Just a Warning Sign?
Most failures don’t happen overnight — they show up as a warning sign first, and catching it early usually means a repair instead of a full replacement.
RGIINo hot water or it runs cold quicklyRegistered
usually a failed thermostat or burnt immersion element, or a pilot light fault on gas units, most repairable without full replacement
Leaking tank or cylinder
in older Raheen and Dooradoyle homes, usually tank seam corrosion after 10–15 years, and once the seam goes, replacement is the only safe route
Strange tank noises
rumbling or banging from sediment and limescale, common in hard water pockets around Annacotty and Bunratty, usually fixed with a descale or element swap
Rusty or dirty water
internal corrosion or a failed anode rod, once the lining goes, replacement is the only safe route
Low hot water pressure
hot tap only affected, usually a blocked dip tube, partly closed valve, or scale inside a vented cylinder
Beyond individual symptoms, replacement usually makes more sense than another repair when the system is over 12–15 years old, when you’ve had multiple repairs already this year, or when the repair quote is close to a third of a new unit’s price. We’ll tell you honestly which side you’re on, even when it costs us the repair job.
Our Installation Process
Free site survey
we assess water pressure, pipework, tank location, gas or electrical supply, and ventilation, sized to your actual household, not a one-size-fits-all default
Safe removal and full fit
often a €old unit removed, new cylinder fitted, pipework and connections completed, pressure relief valve and expansion vessel fitted, thermostat set upelectrode, not a dying boiler
Commissioning and system testing
flow, pressure, temperature accuracy, valve operation, leak points, and recovery time all tested before we leave
Handover
we walk you through the thermostat settings, the pressure relief valve location, and what to check yourself between services
Gas work is completed to RGII standards and IS813. Electric installations meet current Irish wiring regulations. You get written compliance documentation for the finished job — essential for rental compliance and home insurance.
Water Heater Repair in Limerick — Same-Day Response
No hot water on a school morning, or a system that’s given up with a house full of visitors — we treat these as genuinely urgent. Same-day response across the city and county.
No hot water at all
often a failed thermostat or burnt immersion element
Water too hot or scalding
usually a thermostat stuck on or set too high
Water too cold or lukewarm
heating element failing or a wiring fault
Leaking cylinder
a failed seal, corroded seam, or cracked fitting
Faulty thermostat
replacement costs €100–€300, restores hot water without touching the cylinder itself
Failed immersion element
the most common call we get, straightforward swap in most cases
Pressure relief valve leaking
usually an overheating system or a worn valve seat
Tank leaks and pipe joint failures are traced using non-invasive detection equipment — catching it early avoids structural damage and a costlier replacement later.
Covering Dooradoyle, Castletroy, Raheen, Annacotty, Corbally, Mungret, Caherdavin, and Ballysimon. Call (061) 518 247 for immediate response.
Water Heater Maintenance
A system that’s never serviced fails earlier than one that’s checked annually.
Check the T&P (temperature and pressure) relief valve yearly for correct operation
Flush sediment from the base of the tank to stop it insulating the element and forcing it to overwork
Inspect the immersion element for scale buildup, especially in hard water areas
Check the thermostat is holding an accurate temperature, not drifting
Book an annual inspection so small faults get caught before they become a no-hot-water call
