| Johnny, all this stuff about the water temp aside for a minute... Your stated heat loss seems high to me. Unless, it's a large building, or a VERY lossy smaller one ... How many sq ft is the home ? How would you rate the windows/doors ? A lot of glass ? How much insulation ? You could well be installing an oversize boiler that you will pay for for the next 20 years ... (although, since you have an indirect water heater, the boiler may need to be sized for that...) rbeck, where did that 9% CO2 figure come from ? I'm confused about that ! __________________ The following statement is true. The previous statement is false. |
