A Great Little Fan Aug 03, 2016

I bought this in-line fan to pump warm air into a chase containing hot and cold water pipes. When outdoor temperatures drop below 15 degrees Fahrenheit, the air in the chase falls below freezing, so I was worried that the pipes would freeze. This little fan together with flex duct (I stripped away the outer insulation) solved the problem. I have a thermostat in the chase and a control system that turns on the fan when the chase temperature drops below 40 degrees F. Now I can spend time... more

Crown Boiler Awr210 - 175k Btu - 83.4% Afue - Hot Water Propane Boiler - Chimney Vent Review Aug 05, 2016

Installed this boiler in June 2012 - Very good documentation - Very good response from customer service when I had a question about the controls. Checked on higher efficiency rated boilers but could not justify the much higher price. Until you make up the increase in price with the savings in fuel the unit would be 8 - 10 years old.

Installation straight forward and worked well but then it became a nightmare. Multiple calls back and a real money looser. We put it to bed by bypassing the pressure switch (and installed a voltage sensor on the electric clothes... more

Great Unit, Love It Mar 10, 2016

Installed it in a 16ft x 20ft building. Works extremely well. Keeps the building at 50 degrees when unoccupied, then heats it up to 70 degrees fast when occupied.

Best Inventment Ever! Aug 05, 2016

Our main house is cooled by a 2.5 ton conventional a/c. I replaced that unit in June with a new American Standard (Trane) a/c. On the back of the house is a Florida room 44' x 12' that was not air conditioned. Three sides of the room are sliding glass doors, circa 1989, overlooking a lake and facing east. The summer sun and Florida temperatures made the Florida room un-usable during the daylight hours. A load evaluation recommended a 3 ton unit to cool the Florida room. After much... more
