Install a 93%+ efficiency gas boiler to reduce energy costs

Why settle for a gas boiler that’s only performing at 70% capacity if you can have one that delivers 93%+ efficiency and reduces your energy usage? Gas boilers that are more than 10 years old are prone to reduced efficiency. They also consume more energy driving up utility bills. The sooner you replace them the more you will save. Harris Heating & Plumbing installs technologically advanced heating systems for residential and commercial properties in Dublin, Wicklow, Kildare and Meath.
