Removed 15 year old standard efficiency Ferroli System Boiler and replaced with the new Condensing A Rated Ideal Vogue Combi Boiler. This boiler delivers 15 litres of hot water per minute at high pressure throughout the house with a 3 bar calpeda booster pressure. Teenage daughters loving the new high pressure showers and no need to ever pre-heat the hot water again = one very happy family!!
