What's the Temp?

摘要

I ask about temperature all the time. I'm nosy that way. Techs call in with problems or questions on their boiler service calls and frequently I ask questions about temperature to help in the troubleshooting process. It used to be mainly the temperature of the supply water leaving the boiler and occasionally the return water from the system. Things were simpler back then. Somewhere along my 35+ years of doing this, the question of the outdoor temperature started to complicate my life. Contractors were installing separate indoor-outdoor controls on boilers that had a digital readout. Back then, digital readout was pretty special. Now, we take it for granted. It is also on your Smart Phone. The kid probably has it on all of his devices.
