I had a Worcester 19/24 CBi boiler installed in 2004. Amongst other problems it has had the heat exchanger replaced 4 times due to leaking seals. It has now leaked again 11 months after the heat exchanger was replaced under a British Gas maintenance contract. British Gas have tested a sample of the water in the system and say it is causing the leaks, and so want to charge me for a power flush and relacement of the heat exchanger for a total of £1500. Worcester Bosch have also tested the water, and say that although the water has problems it shouldn't have caused the leaks to the extent that have occured, but won't admit to any design fault, and won't admit to this boiler having this problem. They have offered a replacement Greenstar 24Ri at a discounted price. (Installation not included). If British Gas are to keep maintaining the system then they will want to power flush the system at my cost (£1,000).
Does anyone know if this boiler is prone to leaks (a number of heating engineers have said it does)? Any advice on how I should proceed?
