Buderus GB142 Boiler Reviews - The Buderus GB142 Wall Hung Boiler is gas-fired and can be retrofitted for propane from natural gas. The Buderus GB142 gas-fired boiler also takes traditional North American boilers and gives them a European look and feel to boiler installation and design. The Buderus GB142 offers efficiency up to 94% AFUE, which is close to the maximum efficiency you can get from any gas-fired appliance.
Both the European look and the efficiency make this boiler a good buy. Firstly, in Europe, many of the boilers are hung on the wall, and this saves space, and secondly, the high-efficiency rating makes for a lower gas bill. (more…)
Buderus Boiler Reviews - Buderus offers hot water boilers with efficiency ranges from 81.5% AFUE to 95% AFUE* for both Buderus gas-fired boilers, and Buderus oil fired boilers. Selected Buderus hot water boilers can also use PVC venting on selected hot water boiler systems. PVC pipe venting is typically for condensing furnace and boilers where the flue temperatures are low.

Crown Aruba 3 Boiler Reviews | Consumer Ratings - Richard, I’m considering purchasing a Crown Aruba 3 boiler model# AW1128. Your web page suggested that I e-mail you to get a technical review. I thought it was a great idea! I’m considering installing this Crown boiler along and possibly a crown indirect hot water tank along with it.
I plan on downsizing in the next few years and the existing boiler is about 40 yrs old. HWT is about 17 yrs old. I get a very good price through a family member employee of the plumber’s supply store. I live in Northern NY with cold winters and nice summers. One concern is using the boiler to heat hot water all summer seems excessive but I’m told it’s the way to go. Thank you for any help or advice you can give. (more…)

HVAC Tip - Did you know the human body produces approximately 250 BTU/h when sleeping? Here is a basic list of the approximate BTU/h produced by the human body for various activities:
Watching Television - 400 BTU/h (any sedentary activity)
Cleaning the house - 700 BTU/h (moderate activity)
Mowing the Grass w/push mower - 1800 BTU/h (heavy activity)
Running a marathon - 2400 BTU/h (extreme activity)
The number of people occupying a dwelling or space is a consideration in the load calculation for sizing air conditioning systems simply because humans do give off heat. BTW, the Matrix over blew the numbers. In the movie Morpheus states humans give off over 25,000 BTU's. Only the author of this website is that hot..............))))))
