Lots of factors go into  that, such as what your local electric rates are vs gas rates, but as a general rule of thumb, you're better off sticking away from them north of that line.Here is a link from the department of energy that shows the correct temperature that heat pumps become inefficient.http://energy.gov/energysaver/articles/air-source-...I can tell that even here in ky my largest bills by far come from a duplex with heat pumps.

Now, I can do a lot of things with the space, however, as it is dry, has a loading dock, is at least temperature controlled (might be climate controlled as the building has been used for document storage for a decade), and has a dry fire suppression system installed and working.

Naturally, it has warmed from the abnormally low temperatures of the mini-ice age.

-Maintain the temperature of the Premises at such a level to prevent breakage of pipes or other damage to the Premises.Would you charge your tenant the $200 it cost for the fix?

I don't know what the temperatures are in Denver.

When the weather turns cold or when the weather turns hot, we will check in to make sure the unit temperature is maintained at a comfortable and safe level.

I can set a range that they guests can set the temperature to.

The four layers are incorporated into one product by heavy pressure and high temperature.

thinking in aspect of ice, snow, wind, and also temperature in summer and winter.

It's possible that there is a correlation between global temperatures and inherent weather patterns, but that doesn't mean there is any causation.
