Additionally, we have installed thermostats on the supply piping in the most vulnerable section of the basement which automatically turn-on the heat wrap if the temperature of the pipe drops below 1-2C.

My parent's house (That I grew up in) was owned by some real weirdos that left the place in very poor condition.To this day, some of the places in that house will give me the willies if I'm there by myself.My wife, who is quite the logical individual, proposed that as a child (a very small child) who was already intimidated by the size of the house, I may have had some child-like fears of some of the spaces.Even though the house has been renovated, her idea is that something really subtle... like smell, felt texture, or even temperature may be causing a buried memory of those very child-like fears.Makes sense to me, anyway.

If his property is somewhere with extreme temperatures, then it can change things.

I ask because the house has not been heated and there have been freezing temperatures. 

There’s a lot more obviously but these are the higher level daily changing metrics you want to monitor to gauge the temperature of the markets.

That is the Bromine that we use in the Tub which works much better than Chlorine at the higher temperatures.

This lowers the inside temperature significantly.

Here are a couple things you forgot to mention- you shut the electricity off on us the day we moved in (with 100 degree temperatures), you left a non working washing maching in the laundry closet filled with brown water and made us take it out... you also had us walk through the back yard with you and there had been drought for days, so the mud wasnt visible... and in your lease it stated that we were to make you aware of any changing conditions of the property... also i first approached you about the issue asking if we could and i quote “seed the back yard ourselves and just take it out of rent” i never asked you for sod, i never demanded it- actually the first person to mention sod in our emails was you! 

Who’s out there checking their tenants temperature for May rent?

Peak oil is such a Y2K thing.Yes people will always need a place to live, but does it have to be in a place where the temperature and humidity both hit 100 for months and the water has already been used by every other big city in the state?
