Hello everyone. I’ll try to be as brief as I can possible be, so please, bear with me…
I’ve been looking for a replacement for my almost 20-year old oil-fired boiler since last year when I had to replace its DHW coil (pinhole that leaked into the block and caused pressure-relief valve to release some water every
few minutes). Not a big deal, BUT the plumber who changed the coil told me that my Burnham series 7 is well known in the industry as a “leaker” and that he was actually surprised the cast iron block made it this far. Basically he
said something like: “it can last another 20 years, or it might not even last another 20 months”. So last thing I want is to find myself in a situation where I’m forced to put another oil-fired boiler in my basement (or replace
my 60+ year-old oil tank).
I have natural gas pipeline running on my block (National Grid) and they can run it into the house for free. Here, on Long Island, the bread and butter for all the HVAC guys is “oil-to-gas” conversions. By the way, I’m not sure why
they call it conversion. Nothing is being converted. Old equipment is *replaced* with one that uses different fuel type, that’s all. So last spring I interviewed a bunch of HVAC contractors. Quotes ranged between 11-13k,
which is outrageous. Not one of them mentioned or offered to run a heat loss calc on the house or to even look at the type of radiation I have throughout the home. Luckily last May, National Grid declared a moratorium that
suspended all new gas installations on Long Island claiming supply issues. The moratorium lasted until end of November. This gave me enough time to study up on hydronics, do more research on equipment and also find/read a few VERY informative articles on this site that helped me a great deal (thanks Dana!).
With all that being said, I guess I will be doing my own switch-over to natural gas once this heating season is over. If I run into issues (piping wiring etc.), I’m hoping to get some answers on this website (that’s why I signed up).
Will post more information about the house, equipment that I tentatively chose, etc. soon.
