Combi boiler installation in Westmeath

Westmeath has gas in both of its big towns, and most homes there still don't use it. In the 2022 Census, 19% of households in Athlone heated with gas and 44% with oil; Mullingar was 20% gas and 48% oil (CSO, built-up areas file). Kinnegad and Moate are both 19% gas. Off the network, Castlepollard is 60% oil and Killucan-Rathwire 68%.

Across the county, 50% of homes heat with oil and 22% with coal, peat or wood. 3,794 homes had a gas meter in 2024 (CSO, Networked Gas Consumption 2024). It's also cold for the midlands: on Met Éireann's 1991 to 2020 averages Mullingar gets about 2,162 heating degree days a year, the third most of any county's largest town after Letterkenny and Monaghan (our calculation from the 1 km grid). Size a Westmeath boiler for the radiators as well as the showers.

The county figures hide a split that matters for a combi: towns on the gas network and the countryside on oil. These are the 8 biggest towns in Westmeath, with the share of households on each fuel in the 2022 Census.

Source: CSO Census 2022, Small Area Population Statistics, built-up areas, table 6.5 (households by central heating), and CSO table F1015 (population of towns), read 30 October 2026. Shares are of all households, including those that didn't say.

The median Westmeath home with a gas meter used 7,259 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 €940 a year. That sum is ours.

Met Éireann's 1991 to 2020 averages give Mullingar about 2,162 heating degree days a year, 4% more 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 more heat here over a winter, so size the boiler for the radiators, not just the showers.

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.

All of County Westmeath, including Athlone, Mullingar, Kinnegad, Moate, Kilbeggan and Killucan-Rathwire. The six biggest towns had 54,762 people between them in 2022 (CSO Census 2022, table F1015). Put your town or Eircode in the form and we pass it to one installer who covers your county.
