Peace, 46 degrees isn't cold when you're wrapped up and working. Sitting down and relazing in it is a different story.
Bobert, that is the same figure I walked into when I came home. The furnace - a new one - had stopped sometime during my six days gone - there was no hot water in the expansion tank so it had been some time- and it was blamed cold in here. The first floor thermometer said 46, the apartment up top read 45.
The furnace had a burp in it and wouldn't reset. Luckily, my go to guy was home and able to come within the hour and work on it, while I sat in the downstairs kitchen (this is a three-floor house museum) with the oven on. By the time my guy had reconnected things, the temperature was up to about 60 in that room but it took most of the night to get the whole house warmed. When walls get cold it takes awhile.
Our outdoor temperatures hover right around 40 these days so it isn't freezing much overnight yet.
I should have given you some handwarmers I took along to the Getaway, Beaubie. If the temperatures had dropped into the polar digits this year I was ready...
