The boiler was working fine until I had it serviced last winter. The engineer said to call him if the needle went into a red zone. It did and I called him again and he drained some water off and said if it happened again it would be expensive!. It did go into the red zone so I called another engineer. He said it had been leaking at the exterior outlet and replaced a part. This was again last winter
After that although the needle went close to the red zone it always returned to the safe zone when turning off. Just recently the needle is one section of the red zone at the right of the dial. Before I call another engineer can anyone give me an opinion and advice as to what this means.
Thanks in advance
