I just talked to cozy heat and he r an eco 40 with 500 gallons of storage and expansion tank. I would like to get your advice before buying. I have a two story house with a walk out basement. Whole house is about 5000 square feet. I will have a detached garage in the future. A lot of glass facing north "view". It is a timber style home High ceilings. All heating will be with radiant in-floor. I live in New Mexico at about 7000 ft in the mountain's. It gets in the 20's at night but back into the 40's in the day. This will be my only heat source and will be my DHW source. I am planning to install in the next month before winter gets into full swing. I know you need more information, but with what I gave you what would you choose an eco 40 or 60? Larger storage?
thanks
