Sounds like a game of roulette or blackjack. 

I'd check the wire temp at both ends and the motor before starting and an hour or so after running. 

I am not one to gamble like that.If I am going to gamble then I go to Las Vegas and play black jack.

Does anyone know if the Florissant law also applies to Black Jack? 

It's like winning a big in blackjack and sticking around a bit longer for fun or extend the streak a bit more.If I had to start now, I would have to think about buying at near peak and see what upside do I have.Terry

I don't buy extended warranties for my car and don't buy insurance when playing BlackJack Lol. 

Orchards have "less" risk....but this is like saying row crops are like craps tables and orchards are like blackjack.....the odds can be against you from the get-go.

Obviously keeping boilers or other running as efficiently as possible is the goal, but outside of keeping the temp at a reasonable level....don't have the boilers cranked up to high....I really haven't found a way to reduce this without putting I new windows or a completely new system or have the residents pay for it.  

Your best bet would have been one hand of blackjack.  

Ok, so any suggestions on how best to solve these issues:This property is a triplex (maybe quad with an efficiency), converted from a SFR, so it's got one hot water heater for the whole building, and one temperature control (hot water / steam radiant heating) for the whole building located in the second unit.I'm thinking the cheapest way to provide enough hot water to the whole building is to replace the hot water heater with a 200 first hour rating hot water heater so I don't have to mess with the plumbing too much.For the heat, I don't know if it's easy enough to separate the heat out to each unit, if not, my thought was to just leave the temp at say 62, and not give them access to the temp control, and let them get space heaters to make up the difference.
