Ever wonder how heating systems worked? Heard of a boiler but never knew what it was? Or heard of it, but curious as to what it looked like? This video will give you a glimpse of how the system works and what it looks like. Ideas for keeping it operating at maximum efficiency will be discussed along with ways to save money on utility costs.

  1. Thanks, MP. Wish I’d seen this before we had our boiler inspected yesterday. (We would have gone with Gateway, but they were booked until Nov. 16.) Ours is hot water, but it was still useful.

    Question about rates: the other boiler guys recommended replacing the expansion tank and quoted me $500-600 to replace the tank, fire up the heat, and check all the radiators in our 5-story brownstone. I checked online and #60 boilers are going for less than $100. Is this a legit quote?

  2. Great info. I love reading/watching/learning about the cool stuff involved in keeping up these great old houses. Bought my place a year ago and this sort of thing (and the forum in general) is just what I need.

  3. Right, so it takes much more pressure in a hot-water system than it does in a steam system, for obvious reasons. Gateway told me my steam boiler should only be at about 1 PSI. Which it is.

    Thanks, Drew, for the vote of confidence in Gateway.
