Age Chart for Heating Units

Heating Age Chart

To bad it is not copy/ paste like the Hot water heater one you put up.
But good to have.

This is John Bowman’s old site that was to replace NACHI about four years ago, or so. At least, that was the plan. He called it NUPHI or something like that…

Thanks! Now what am I going to do with my Preston’s and Carrier Bluebook?

Water Heaters, also :mrgreen::mrgreen:


Did someone mention websites??? :roll::twisted:

Website? Website? You wanna talk about websites?:wink:

Thanks Ian !

Thanks this will help out a lot…:slight_smile:

Great information Ian, Thank you…

Great chart but I notice that BAXI bloiers are not listed here, which is what I am looking for at the moment.
