Switching to gas heating - Navien - any input?
Hello, my current oil heating system needs oil tank replacement and furnace needs new burning chamber; investing 4K into 30+years old system which at this point I think doesn't have even 60% efficiency; I'm considering gas boiler system.
Currently I'm looking at Navien CH-180 which is supposed to be 98% efficient with on-demand domestic hot water.
My heating runs on hot water radiator, switching to gas boiler heating system shouldn't be very complicated. After tax credit and rebate, this will cost me about 1.5K more than maintaining the old system, so is it worth it with this Navien brand and gas heating instead of oil.
Any input will be greatly appreciated. Thank you for your time and efforts.
