Three days without any water or electricity during freezing temperatures. 

When I asked her if she let the water drip she said she didn't know she had to let the water drip although on the news they constantly told people to let the water drip due to the temperature dropping to the 20s for 2 days and ice was on the ground.

I have a remote vacation rental so I put a smart thermostat in it so I could monitor/control temperature remotely.

Meanwhile, a mini split is more like 250% efficient, because it uses one unit of energy to move 2.5x as much heat.This is effected by temperature.

A landlord must repair a condition if a tenant gives notice of a condition, the tenant is not delinquent in rent payment, and the condition materially affects health or safety of the tenant or is due to the landlord’s failure to supply hot water at a minimum temperature of 120 degrees Fahrenheit.

@Justin BrickmanMy recommendation would be to get WiFi thermostats and control the temperature remotely.Depending on state solar does not provide a significant ROI

Probably not a great place to get investment advice or even take the temperature of the market.In Cleveland we are still seeing good results in downtown which is underserved by overpriced hotels, but we are also shifting our focus to "drive-to" vacation-y spots within an hour or so of the city, and unique stays. 

A stuck open toilet flap water usage is only limited to the maximum per gallon flow from the fill valve, which despite what the literature says on flow rates will vary depending on time of day, static system pressure, and even the water temperature at different times of the year.  

I put my hand in the shower and the water temperature seems normal. 

A minimum temperature of 55 oF must be maintained inside your Rental Unit at all times; damage to the Premises resulting from you not doing so is your sole responsibility.
