I have been researching combi boilers for what seems like forever trying to come to an answer on what size combi boiler is right.
3000sf 2 level house with lots of large windows located in Northern Ohio. House has new windows and doors with added insulation. 1 kitchen and 2 bath.
I currently have an 80,000btu 80% unit that struggles to keep up in the winter and the propane bill proves it. My Nest report shows it's running 50% of the time in the winter $$$.
Using simple square footage calculations, I need a 150,000btu unit.
The quote I received listed a Navian 160kbtu unit.
On the Slant/Fin app, it recommends 150,000btu unit, but my requirement is ~112,000. See pic.
Everything I keep reading about ~150,000btu combi units and similar sized houses has replies stating that it's "WAAAY too big". I'm trying to do my due diligence by researching on the forums but what I read only leads to more confusion and make this decision that much harder.
I'm currently looking at the Navian NCB240/130H
Thanks in advance.
