sorry to go off topic OP.
I'll pull this back onto topic.
I'm using a super efficient 50 gallon Rheem Marathon unit with a plastic tank and an efficiency rating of .94. Who in the government is to tell me that this was a bad decision?

There can be significant installation costs to retrofit a tankless water heater into existing construction.
Electric tankless units will require an upgraded electric feed to the water heater (which may then require a 200 amp service, if one isn't already in use).
Gas units will require a larger gas supply line, as well as a new stainless steel flue that is specifically for tankless hot water heaters. The old supply line cannot be reused, it isn't large enough. The old flue cannot be reused, due to the amount of heat that will pass through it.
I installed the super-efficient Rheem Marathon without retrofitting anything. The plumber was in and out in no time, the installation cost was much less than I expected (little more than a service call), and my power bill has dropped noticeably.
You can have these type of nanny state rules. I'll continue to happily choose the option that is BEST for ME.
Agreed. There is nothing wrong with a conventional water heater. Consumer Reports did a comparison just over a year ago and it was clear that the up front costs might take up to 20 years to pay back with a tankless heater savings.
