The release period is up to different conditions of temperature, humidity and the quality of the surface.

It turns out she had been living in her car for three days in temperatures as low as 26°.A transfer was set up and we brought her back home.

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.

"In the wealthy, northern suburbs of [Athens], where summer temperatures often hit the high 90s, just 324 residents checked the box on their tax returns admitting that they owned pools.

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.

I would not shut off the water heater at the gas valve because you would have to relight the pilot later and leaving it on at a reduced temperature will help prevent rust in the combustion chamber and it probably won't use more gas than the minimum charge anyway. 

The plan would be to install it so you can mix cold water into the hot water line coming out of the hot water heater to reduce the temperature of the water going to your fixtures in the house from the 150 degrees coming out of the hot water heater. 

We have tings such as infrared cameras, temperature and humidity meters, mold air and surface sampling equipment, and many years of experience.  4) While mold is not regulated, asbestos and lead are very highly regulated, with potential huge fines, even time in federal prison. 

So, while the same amount of heat (more, actually) will get taken out of the heat exchanger, the output temperature will be lower.

(1) Since it's in a freezer so it would be subjected to freezing temperatures.
