I’m new to all of this and just started my research and getting estimates. I’m located in Nassau county Long Island. I have ability to convert to gas as it will be coming to my street. I currently have a slant fin high efficiency oil boiler that is only 8 years old at 79,000/85,000 BTU. I have a split level approx 2200 square feet. Basement/ lower level has baseboard which we never need to use. 5 zones of in floor hydronic radiant heat and another zine of forced hydronic air via the air handler. We only put that on when it’s less than 45 degrees usually as the floor heat keeps the house qiluite comfortable. I keep the house set at 68 mostly.
I have a 45 gallon HTP superstore ultra indirect that is 7 years old.
HMy house is a all brick 4 bed 3 bath split that was completely gutted 8 years ago. My current system has no problem keeping up even when below freezing outside.
Have had 2 estimates so far
1. Burnham series 205 130,000 BTU
-This company says I need a new indirect water heater or a Bradford white water heater. Says a HE boiler not necessary that this model is a workhorse.days can’t use current indirect.
2. Burnham ES25. 140,000BTU. This co. says I can use current indirect with it and all our current hook ups are perfectly fine. He said just an easy swap out of the boilers.
I questioned why so big and he told me about house square footage and this size is appropriate.
Both of these bids the boiler is so much bigger than what I have now that is having no issues, it’s just we want to convert to gas. Both companies are respected and do tons of conversions in my neighborhood but I am uneasy. Getting additional quite today but who can I call for central Long Island for another quote that will sell me an appropriate sized system? Am I missing something?
I know about the heat loss analysis but my system was installed brand new 8 years ago into a basically rebuilt home that is well insulated. No changes since then
Thanks for any help
