Plumbing & boiler questions — answered honestly.
Real answers to the questions Kildare homeowners ask us every week. Written by an RGII-registered engineer, with current Irish pricing.
Boilers
How much does a boiler service cost in Ireland?
A standard gas boiler service in Ireland costs €149 and an oil boiler service costs €199. The price includes a full strip, clean, flue-gas analysis and a signed service certificate from an RGII-registered engineer.
How often should a boiler be serviced?
Every gas and oil boiler in Ireland should be serviced once every 12 months. Annual servicing is a condition of nearly every manufacturer warranty (Worcester Bosch, Ideal) and is a legal requirement for landlords.
How much does a boiler replacement cost in Ireland?
The cost of a new A-rated boiler replacement in Ireland depends on the boiler, your existing system and the controls you choose, so we quote in writing after a free survey. Every quote includes the boiler, installation, RGII certification, manufacturer warranty registration and removal of the old unit — and our current boiler sale takes €250 off every gas boiler replacement.
How long does a boiler installation take?
A like-for-like combi boiler swap usually takes one working day (6–8 hours). A full system upgrade — new flue route, new controls, system flush — typically takes 1 to 2 days.
What are the signs my boiler needs replacing?
The clearest signs your boiler needs replacing are: it is over 10 years old, your gas bills have crept up, it breaks down more than once a year, the flame is yellow instead of blue, it leaks water, it kettles or rumbles, or parts are no longer available.
Heating
Why is my boiler losing pressure?
A boiler losing pressure almost always means a small leak somewhere in the sealed heating circuit. The four common causes are a leaking radiator or valve, a failed expansion vessel, a weeping pressure-relief valve (PRV), or a pinhole leak in pipework.
What is powerflushing?
Powerflushing is a deep clean of your central heating system using a high-flow pump, chemical cleaner and magnetic filtration to remove built-up sludge and rust. It restores full radiator output, lowers gas bills and protects your boiler warranty.
Why are my radiators cold?
Cold radiators have one of three causes: cold at the bottom (sludge build-up — needs a powerflush), cold at the top (trapped air — needs bleeding), or completely cold (closed valve, seized lockshield or pump fault).
Plumbing
Why is my immersion not heating water?
An immersion not heating water is almost always one of four things: a tripped overheat thermostat, a burnt-out heating element, a faulty timer/switch, or a tripped RCD in the consumer unit.
