In the last article, “Is your boiler stealing your money?“, I discussed why most boilers are ripping you off. Contrary to what almost every HVAC saleperson or tech will tell you, your boiler does not operate at 84% efficiency. It doesn’t operate at 80%! Heck, much of the year, it doesn’t operate at 50% efficiency!
To review, the reasons for this include:
High operating temperature
→ Outrageously high standby losses
In this article, I’m going to discuss how to do it right. But if you’re too lazy to read the entire article, stop right here and go to the Energy Kinetics website.
If you have a boiler, chances are, it’s wasting a lot of energy!
At today’s fuel oil costs, (~$3.50/gallon in March 2011), it’s more important than ever to conserve. This is definitely one of those cases where it pays to do your homework.
What if I told you there’s a good chance that your boiler is half as efficient as they told you? You wouldn’t be happy, would you?
Let me tell you a personal story. When I moved in my house, it had a relatively modern boiler, rated at 82% efficiency. It heated the houe and the water. I figured that was pretty good – no need to upgrade, right?
