Hi folks, new to the forums. I have an electric boiler pumping hot water to a 5 zone system in my house. One of the control valves stopped responding a couple of years ago and was replaced. Now the same control valve has an intermittent buzzing sound and the motor seems to be constantly really hot. A plumber (should have done it myself!) replaced the motor this morning. I got the feeling that the heat in that zone was not what it used to be as well. Any other suggestions?
