In Tipperary, 60% of homes heat with oil and 12% with gas (Census 2022), so most combis are oil. 8,026 homes had a gas meter in 2024 (CSO). Of its ten biggest towns, these have two homes in five or more on gas: Clonmel (61%), Carrick-on-Suir (45%) and Ballina (61%). Published prices: a gas combi swap has a median of €2,600 across 12 installers, and an oil boiler €3,000.

What's different about a combi in Tipperary
Outside Dublin, Tipperary has the oldest housing of any county: 47% of homes were built before 1980 and 20% before 1946 (Census 2022). Old farmhouses and town terraces mean regular boilers, cylinders, and back boilers behind the range or the fire, so a combi here is more often a conversion than a swap.
Gas is in the south of the county. Clonmel is 61% gas and Carrick-on-Suir 45%; Nenagh, Thurles and Roscrea have almost none, at 1%, 0% and 1% (CSO, built-up areas file). Across the county 60% of homes heat with oil, and 8,026 had a gas meter in 2024 (CSO).

Gas or oil, town by town

|---|---|---|---|
| Clonmel | 7,178 | 61% | 19% |

What changes the job in Tipperary
- Gas combi swap. Where there's a gas meter, a like-for-like swap is the usual job, fitted by an RGI. Median published price €2,600, middle half €2,199–€2,800. See every published price.
- Oil combi. 60% of Tipperary homes heat with oil. An oil combi or a standard oil boiler is fitted by an OFTEC-registered technician, often outdoors in its own casing. Median published oil boiler price €3,000. See oil combi boilers.
- Conversions in older homes. 47% of Tipperary homes were built before 1980, against 42% nationally. Most of those started with a regular boiler, a cylinder and an attic tank, so a combi means taking them out: median published conversion €3,400. See converting to a combi.
- Big detached houses. 59% of Tipperary homes are detached, against 41% nationally. With two or more bathrooms in use at once, a combi shares one flow of hot water; a system boiler with a cylinder may suit better. See combis for large houses.
Running costs in Tipperary
The median Tipperary home with a gas meter used 7,160 kWh of gas in 2024, against 7,771 kWh for the State (CSO, Networked Gas Consumption 2024, table 5B). At SEAI's unit price of 13.00c a kWh for gas in band D2, including VAT and before standing charges (SEAI, 1 July 2026), that's about €930 a year. That sum is ours.
Met Éireann's 1991 to 2020 averages give Clonmel about 1,959 heating degree days a year, 6% fewer than the Irish average of 2,079 (Met Éireann 30-year averages; degree days are our calculation from the 1 km grid, base 15.5 °C). The same house needs less heat here, so a combi sized for hot water usually has output to spare for the radiators.
Oil is priced the same everywhere: kerosene was 12.60c a kWh on SEAI's 1 July 2026 schedule prices, against 13.00c for gas. See combi running costs for the cost per shower and per year.

FAQ
Questions people ask
How much is a combi boiler installed in Tipperary?
We found no Tipperary installer that publishes a price. Nationally, a like-for-like gas combi swap has a median published price of €2,600 across 12 installers, a conversion €3,400 and an oil boiler €3,000.
Which Tipperary towns have gas?
Clonmel (61% of households on gas in the 2022 Census) and Carrick-on-Suir (45%). Nenagh, Thurles and Roscrea are almost all oil.
Do most homes in Tipperary need an oil or a gas combi?
Oil, on the 2022 Census: 60% of Tipperary homes heat with oil and 12% with gas. A meter box on an outside wall means gas; a tank in the garden means oil.
Is there a grant for a new combi boiler?
No. In SEAI's own words: "We do not give grants for new or replacement fossil fuel boilers, such as gas or oil" (SEAI, read 29 October 2026). You may get the €700 heating controls grant if your home was built and occupied before 2011 (SEAI), and with a combi SEAI requires an extra heating zone as part of that work. The €2,000 boiler scrappage grant only applies when a heat pump replaces the boiler.
