Boiler service in Dublin 12

Nine divisions of mid-century houses on gas

Crumlin's housing is mostly pre-war and the Census shows it: 55% of homes in Crumlin F and 50% in Crumlin A were built before 1946, and across the nine Crumlin and Walkinstown divisions 37% were. Walkinstown came later: 9%, 13% and 11% of homes in its three divisions date from before 1946, with most of the rest built between 1946 and 1980.

Almost nothing is new. Only 2% of Dublin 12's homes were built in 2011 or later, against 8% across Dublin. And 90% of households live in houses, with Walkinstown A the one division with a real share of flats (31%).

Gas runs through all of it. Crumlin E has the highest gas share of the nine at 87%, and even Walkinstown A, with its flats, is 63%. Electric heating is 8% and oil 4%, both below the Dublin average.

What that means for your boiler

• Older houses, older systems. A 1940s Crumlin terrace has usually been through two or three boilers. Many still have a regular boiler with a hot water cylinder and a tank in the attic, and some a back boiler behind the fireplace. The yearly service is the same job, but the engineer should check the flue and ventilation with extra care on an older installation.
• Gas, so an RGI. With 78% of homes on gas, almost every service in Dublin 12 is RGI work. Check any engineer's name on rgi.ie.
• Heating controls grant. SEAI's €700 heating controls grant is for homes built and occupied before 2011 with no or basic controls (SEAI). With 98% of Dublin 12 homes built before 2011, most qualify on age. It must be approved before any work starts.
• Owner-occupied and council. 63% of households own their home and 12% rent from the council; only 15% rent privately. Private landlords here should read landlord gas safety certificates.
