I always thought Weil McLain was the best. I planned to use Ultra Plus 230 Condensing high efficiency boiler w/ Ultra Plus 40 indirect heater but web searches reveal issues and poor reviews. Now I need Subject Matter Experts like yourselfs to help me.

I have the funds to do this once but don't have the funds for costly repair bills if there are future issues.

My most important criteria: RELIABILITY.

I can vent through the chimney or go out a wall.

Please provide your opinion for what system / manufacturer I should use and why.

Thank you in advance!!!
