Current building regulations state that any replacement or new gas-fired boiler must be a condensing boiler. Older boilers convert as little as 60% of the fuel they use into heat which has a big impact on the cost of heating your home. Infinite Heating specialise in installing condensing boilers and renewable energy products from Worcester Bosch. These modern condensing boilers improve efficiency to over 90% which could save you a minimum of 30% per year on your home heating bills.
