Why Should I Service My Gas Boiler?

The primary concern involves safety - poorly maintained boilers increase carbon monoxide poisoning risk. Ireland averages six people dying each year from unintentional carbon monoxide poisoning in their homes, typically from central heating faults.

Additional Benefits:

  1. Insurance Purposes: Warranties and policies require proof of proper operation; annual service provides confirmation
  2. Avoid Expensive Repairs: Minor issues identified prevent costlier future repairs
  3. Decrease Gas Bills: Efficient operation reduces energy consumption
  4. Avoid Replacement: Regular servicing prevents total boiler replacement necessity

Three DIY Checks to Perform Before Your Service

  1. Check System Pressure: Pressure gauge should read between 1 and 1.5 bar when cold; refill using external filling loop if low
  2. Bleed Radiators: Cold tops/warm bottoms indicate trapped air; use radiator key to release; recheck boiler pressure afterward
  3. Listen for Trouble: Run heating 15 minutes; unusual sounds like "kettling" or excessive "gurgling" suggest sludge buildup requiring power flush quotes

How Often Should I Have a Gas Boiler Service?

Annual servicing ensures operational efficiency and safety. Efficient boilers consume less gas, lowering energy bills. Regular maintenance prevents warranty early termination and extends boiler lifespan.

Landlord Note: Legal requirement mandates annual Gas Safety Certificates for all gas appliances.

Frequently Asked Questions About Gas Boiler Servicing

A one-off gas boiler service by an independent RGI technician typically costs between €100 and €150 including labour. Energy providers also offer annual service plans ranging from €100 to €200.

You should have your gas boiler serviced once a year, ideally before the heating season. Annual servicing keeps your boiler running efficiently and safely, and helps avoid costly breakdowns.

Only a Registered Gas Installer (RGI) should service your gas boiler. You can verify an installer is registered through the RGII website. We recommend getting two or three quotes before selecting a provider.

Warning signs include unusual noises, a yellow or orange flame instead of blue, the boiler taking longer to heat up, increased energy bills, and the pilot light frequently going out.
