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.

I don't think this is an example of american ingenuity as we did not "invent" tiny houses, although we will clam to have 50 years from now like the steam engine and light bulb.

Oh Steve, that's just on paper, don't worry about it, full steam ahead!

(This means we are moving full steam ahead towards closing their loan).

I'm consumed with the idea and have to solve this riddle.How could a multifamily owner use their property to generate an income steam equivalent to their gross rent?

If not, perhaps steam/moisture from the shower is causing a short-Check all the other connections on the circuit while you're at it-Is there a leak behind the wall coming from the bathroom and getting to the GFCI wiring?

Lots of newbies here to but you seem to be a real go getter and are definitely moving full steam ahead.  

We also require our tenants to have the carpets professionally steam cleaned when moving out.

Possibly, or for hiding passengers of the underground railway, or perhaps it's simply an old steam tunnel and there was a shared boiler/heating plant in the neighbourhood at one time.

I think that sound I'm hearing is the steam coming out of Bill Gulley read Bill's comment (posted 10-13 at 7:22 PM) in this thread regarding why.
