This is for Tempe (shows the complexity of this issue): d) Occupancy load; sleeping room.

The best thing would be to make your own spreadsheet so you can manipulate the numbers the way you want.

There are air-source heat pumps that work very well down to zero degrees Fahrenheit, and some work well even into sub-zero temps.

As you found they could be the preeminent energy crowdfunder, making them a temping takeover target for other sites that want to branch out from real estate.   

@Franky Davis also don’t keep trying to emotionally manipulate a engineer.

However, the Verizon rep did warn us that if internet service is slow in our area (which in general it is), that other households may also rely on LTE hotspots as their main internet source and this may slow down service all around :(  I guess this is a temp. solution until we get Comcast internet installed (or AT&T internet improves from a current snails-pace of 3 megabytes per second).  

I was upfront on my current skill level and abilities and was offered a temp to hire position with the company with a 90 day upfront contract period.

But with the VRBO renters, it doesn't appear that I have that sort of flexibility to write in the utility contingency.I'm considering putting in a NEST thermostat in the house and a remote pool pump monitor so I can keep an eye on where renters have set the temps?  

Why would someone leave a window open in 0 degree temps long enough to freeze pipes?

We already did temp fix for 4k which didn't help.
