We are out on our first test with our new to us bolero this weekend Very happy with it but pump seems to be making an intermittent shudder noise with no taps on All that is running is the heater to heat van Is this normal ?
(Maybe this should be split to a new topic as it isn't Insurance related.)
Your intermittent shudder is probably a small airlock in the system or even a slight leak. Check and see if water is dripping from your boiler dump valve first.
