After  installing our HP a year ago and it running well throughout last winter, I thought Id run it up over the weekend after a few months shutdown. It started and ran fine and I shut it down after a few hours then went to check the magnetic filter. Found the filter with quite a bit of flaky debris stuck to the magnetic tube. I don't know whether the debris accumulated through last winter or came from the weekends test run. There was more debris this time than any of the half dozen filter cleans/checks I did in the weeks after installation last year, so glad I checked it.

 

After getting only minimal debris in the weeks after install, I was quite surprised how much flaky grot was in there!

 

Our system is 90% rads so maybe we're going to see more debris than an UFH system, even with inhibitor, but worth checking any filters in your system to make sure they're clear.

Probably best to check them at the end of the heating season, rather than the beginning of the new heating system.

The thing with inhibitors is they deplete, a static system will locally deplete the inhibitor and you may get some corrosion.

 

Enable the pump any seize and it will run the pump a couple of minutes every week or so.

Pump anti seize is enabled. I can't remember exactly how often it operates but the couple of minutes a week rings a bell.
