What's different about a combi in Kerry
Kerry is oil and electricity, not gas. The CSO's figures from Gas Networks Ireland count only 71 homes in the whole county with a gas meter in 2024 (CSO, Networked Gas Consumption 2024). 63% of homes heat with oil, 11% with electricity and 16% with coal, peat or wood (Census 2022). Tralee is 57% oil and Killarney 59% (CSO, built-up areas file).
Kerry is also mild. On Met Éireann's 1991 to 2020 averages, Tralee gets about 1,673 heating degree days a year, the fewest of any county's largest town and 20% fewer than the Irish average of 2,079 (our calculation from the 1 km grid). The same house needs less heat here, so an oil combi sized for hot water usually has output to spare in Kerry's 66% detached houses.

What changes the job in Kerry
- Oil combi. 63% of Kerry 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.
- Big detached houses. 66% of Kerry 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 Kerry
Met Éireann's 1991 to 2020 averages give Tralee about 1,673 heating degree days a year, 20% 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 Kerry?
We found no Kerry 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.
Can I get a gas combi in Kerry?
Not on mains gas in most of the county. The CSO's figures from Gas Networks Ireland count 71 homes in Kerry with a gas meter in 2024. The usual Kerry combi is oil, or LPG from a bulk tank.
Do most homes in Kerry need an oil or a gas combi?
Oil, on the 2022 Census: 63% of Kerry homes heat with oil and 2% 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.
