Natural Gas Benefits

    Instant Heat

    "Natural gas is like an upgrade for my home heating, the radiators heat up so quickly now, great in the cold weather" firmus energy customer, Ballymena

    Constant Hot Water

    With natural gas, you get all the hot water you want whenever you need it, so no more waiting around this winter for the water to heat up!

  • Icon

    Never Run Out

    We always run out of oil at the worst time! A constant supply of natural gas is delivered via an underground pipe straight to your home, which means you will never have to arrange deliveries again!

    New High Efficiency Boiler

    New ‘A’ rated natural gas boilers are over 90% efficient, compared to around 70% for an old oil boiler over 15 years old. An operational improvement in efficiency of up to 20% represents an actual fuel saving of more than 25%. Source: SEAI
