Re: Trying To Estimate Heat Pump kWh Usage
One too many zeros, should have been 40k. Heat loss is roughly heating season therms used x 42. Why 42, the math works roughly out to that in heating climates and because it is also the answer to life universe everything.

Re: Burnham ES2 - ES27 Spill Switch
Sure if they make a unit that that accepts a 24 VAC input to trigger an alarm, using the filter on the web page I could not find one. I'll look again. You could buffer it with a small 24 VAC relay, so a Shelly unit only sees a contact closure.
Seems like the Shelly products are more about power control and little with the monitoring of user connected device with alarm outputs.
Maybe the " Shelly Plus Add-On "
Although their web page would not let me open the documentation for this device, so not getting a real good vibe.
Many things you could do, just don't make smoke.

Re: Is internal circulator needed?
Just for consistency, I believe the Boiler loop is the Primary. The Zones are the Secondary loops.

Re: Cámara Térmica (Thermal Camera Recommendations)
Quite toasty indeed. 50hp cooling tower pump is actually pulling perfectly acceptable amps (208v, 88a) but the wire and contactor is heavily corroded hence the high temps. Even better, you'll notice the date on that thermal photo is back in December and this customer is still running this pump 24/7. The cherry on top is that their second cooling tower pump has been completely down and that contactor is also burned up, so when this contactor finally burns up completely, they're going to have a fun emergency call
Re: Prevent mold in mini-split heads
it gets clammy when it is not super hot!
Does @clammy know about this?
