I have been in the Fire/Hearth/HVAC/Building industries for over 32 years, and the one thing I know for sure is that I don’t know everything. We just try to tell the truth and give honest advice based on our experience, what works and what may not meet the customer’s expectations. In talking with customers, I’m always learning new things; it’s one of the reasons I love doing what I do. That being said, I’d like to offer some advice based on my experiences in the heating industry: Over the last few years many folks have called me because they suddenly have an outdoor boiler sitting around their property with a “Condemned: Do No Use” sticker attached to it, despite the unit being only a few years old. Why, you ask?
