Hello. I have a power max 155 open vented system
system. BG replaced the blending valve as I had tepid low flow hot water from taps and shower. The New valve made no difference to the temperature or the flow. BG says the coil in the tank is full of scale and the part is obsolete. I called Baxi and they confirm. My central heating is perfect. I am reading I may benefit from descaling the coil. Can anyone suggest if this is possible. Costs. Or any other details. Thanks for your suggestions
