actually it seems to be taking more than an hour to dry completely. probably depends on the ink, air temperature/humidity. if i was in a hurry, i could probably carefully cover the ink with some clear packing tape.

Again, I used to live in the area and I'd love to have reason to spend the summers in Ann Arbor when the temperature is Austin is over 100 -- and the Lake Michigan coastline is beautiful place to get away to for the weekend.

The current climate models leave out the variability of the sun but the last 10 years of satellite data regarding the sun has clearly demonstrated that the sun's variability cannot be assumed to be constant on any relevant time scale from daily to multi century.According to my survey of abstracts that I found by searching google scholar, solar physicists, climatologists, and geologists have found that we are presently well within the natural variability found in the reconstructions of temperature for the last 400k years. 

From researching this topic, one thing I know I'll need to check is the lowest incoming water temperature, so I'll probably wait until February to try to capture the lowest incoming water temp, so I can choose the correct size tankless water heat.  

His theory is that part of the reason it is noisier at night is because of the temperature drop causing things to expand/contract in the wall.  

Dwellings shall be provided with heating facilities capable of maintaining a room temperature of sixty-five degrees (65°) Fahrenheit in all habitable rooms, bathrooms, and toilet rooms based on a winter outdoor design temperature of fourteen degrees (14°) Fahrenheit, in accordance with Appendix D of the 2000 Edition of the Standard Plumbing Code.

Once you know your heat load they'll be able to look at the charts for the mini split and tell you if X unit is capable of producing Y amount of BTU's at Z ambient temperature.

There was some plumbing work that required that resulted from a leak in April that one weekend where the temperatures dipped below freezing but otherwise everything was in great condition.  

Towards the high end of that range I would start expecting a slightly larger house and maybe a couple of zones on the HVAC, so I get separate temperature adjustments for different parts of the house. 

@Charles TerrizziWe have two solar thermal systems in production - in a very temperature dynamic environment - and have experienced no durability issues.
