Low NOx cast iron boilers and b vents

Hi, I need to replace my b vent, water heater, and very soon 30 yo Lochinvar boiler. I live in CO, and unless I can find a regular boiler before the stock is depleted, I have to go low NOx. I'm very hesitant to to replace boiler with a high efficiency boiler because of my 180° system, increased initial expense and increased maintenance expenses. I'm planning on mini-splits or a heat pump for cooling and perhaps some heating, but am not ready to go all electric. What is the recommended way to go? Thank you for your thoughts.

    What do you mean by a "regular boiler". Gas fired cast iron boiler? Or a high efficiency MOD CON. What type of boiler is your Lochinvar? There are also copper fin tube boilers.
