I am installing a Four Season sunroom at my house.
Size - 16 L x 11 W x 9 H
Glass is high performance, insulated safety glass with Argon glass filling. Glass has R value of 4.
All walls and roof are glass, with the exception of the back wall which will be the exterior of my brick house.
Room faces west and I live in northeast.
I would expect lowest o/s temps to be around 10, and highest around 90 during summer. I'd like to use this as much as possible but, obviously, will refrain with extreme weather conditions.
I want to install a split Mitzibushi Mr Slim heating/cooling unti.
I figured I needed around 18,000-24,000 BTU's.
Am I correct about the size needed , and can you recommend a particular model?
