What Happens When You Call
Why Regular Servicing Saves Money
What Each Service Actually Checks
Every one of these is a real failure point, not a box-ticking exercise. When we quote you a repair, we’ll tell you exactly which of these is the problem, not just “the boiler needs looking at.”
Types of Gas Boilers We Service
Combi Boilers
most efficient option, best for apartments and smaller semis, heats on demand, no tank, can struggle with two showers running at once in bigger households
System Boilers
best for large families with a cylinder already in place, no attic tank needed, handles multiple bathrooms better than a combi
Combi Boilers
best for older homes, the Castletroy-style three-beds with an existing tank and cylinder setup, reliable if maintained but more pipework means more can go wrong

compact, best for smaller homes and apartments, 10–12 years, good value, ignition lockouts are the usual cal
Ideal Heating
well stocked for parts here, 10–12 years, best when fast turnaround on repairs matters, solid mid-range efficiency

Gas Boiler Repair
— 24/7 Emergency Response
No heat, no hot water, low pressure, ignition failure, lockout, leak, frozen condensate pipe. Same-day response, genuine parts on the van.
Common Faults & What Causes Them
Low pressure
a leak, a failed expansion vessel, or a weeping pressure relief valve
Ignition lockouts
often a €40 electrode, not a dying boiler
High pressure
an overfilled system or a faulty filling loop that hasn’t been closed properly
Diverter valve gone
radiators cold, hot water still runs
No hot water at all
often the diverter valve or a failed thermistor
Boiler switching off mid-cycle
usually low pressure or a blocked condensate trap
Water leaking from the unit
usually a pressure relief valve discharge or a failed seal internally
Frozen condensate pipes
the classic Monday call after a frosty weekend, insulate it before winter and it won’t happen
Thermostat not responding
often a wiring fault or a thermostat that’s simply died, an easy fix once diagnosed
Boiler Noises and
What They Mean
We can diagnose and fix it.
Kettling
banging from limescale on the heat exchanger
Whistling
trapped air or a limescale restriction
Clicking
the ignition electrode trying to spark
Vibrating or humming
loose mounting or a pump starting to wear

What’s Wrong With Your Boiler? Find Out Now
Match your symptom below to see what’s really happening — and what it costs if you wait.
| Symptom | What’s Really Happening | Urgency | Cost If You Wait |
|---|---|---|---|
| No heat, house freezing | Ignition lockout or diverter valve fault | Call Now | Frozen pipes overnight = €400+ emergency callout |
| Low pressure, boiler cutting out | Leak, failed expansion vessel, or weeping relief valve | Same-Day | Small leak becomes full component replacement |
| Radiators cold at top, hot at bottom | Sludge buildup, dragging efficiency | This Week | Power flush later costs €400–650 vs €80 prevention |
| Gas smell or hissing near unit | Safety hazard — leave the house, then call | Emergency | Not a “wait” issue, ever |
| Boiler over 10 years, no annual service | Warranty likely already voided | Inspect Soon | Full replacement instead of covered repair |
| Frozen condensate pipe (winter) | No insulation on the pipe | Call Now | Repeat freezes = eventual pipe replacement |

Old Boiler Removed
and disposed of, system flushed, new boiler fitted and commissioned properly, not just bolted on and switched on
Warranty Registered
Warranty registered in your name before we leave, so it’s active from day one, not left for you to sort out later
Heat Pump Advice
Thinking about switching to a heat pump instead? We’ll explain the current SEAI grants and whether it’s the right choice for your home
Smart Thermostats & Controls
Hive, Nest, and Tado all fit onto a gas boiler system, and weather compensation plus load compensation settings, set up properly, shave a real chunk off your bill. TRVs on individual radiators let you heat only the rooms you’re using.
Boiler Maintenance & Efficiency Tips
Bleed radiators
Bleed radiators if the top’s cold and bottom’s warm
Clean Filter
Clean the magnetic filter yearly
Insulate Pipe
Insulate the condensate pipe before winter
Summer Run Test
Fire the boiler up for ten minutes every few weeks over summer so the pump doesn’t seize
Check pressure
Check pressure monthly, top up if it drops below 1 bar cold
Lower flow temperature
Lower the flow temperature slightly on combi boilers for better efficiency
Seasonal Care
Winter — the big risks are frozen condensate pipes and lockouts from the cold.
Summer — a boiler sitting idle for months can seize the pump, so give it a short run now and then.
Safety Devices Every System Should Have
CO Detector
Pressure Relief Valve
Expansion Vessel
Flue
Gas Shut-off Valve

We check all of these on every service and repair visit.
Power Flushing for Gas Boiler Heating Systems
Radiators hot up top, cold at the bottom — that’s sludge, common in older Limerick homes with cast iron rads, and it drags down your gas boiler’s efficiency over time. €400–€650 for a typical semi, half a day. Magnetic filter fitted after so it doesn’t come back.
Warranty — What Voids It
Missing a single annual service is the most common reason a manufacturer warranty gets voided, along with using a non-registered engineer or not registering the boiler within 30 days of install. Keep the paperwork and the service record, and cover stays valid.
