If I could go back and do it all over again, I would do exactly what Joe is advising and I would be sitting back, fat, dumb and incredibly happy as a multi millionaire.

Part of the code which outlines the temperatures requirements:“There shall be supplied water heating facilities which are properly installed, are maintained in safe and good working condition, are properly connected with the hot water lines required under Subsection C of this section and are capable of supplying water at a minimum temperature of not less than 120 degrees Fahrenheit (120° F) and at a maximum temperature of not more than 140 degrees Fahrenheit (140° F) at all times to each hot water outlet.”https://library.municode.com/n...

I can help analyze that with you if its still on the burners

Also oil burners need a more in depth cleaning regularly.

The difference is that the former must pay for the marketing budget you speak of; the latter has that fat cut out.
