We have one loop with cast iron radiators, but the other two loops are modern baseboard. When we installed a condensing boiler in 2015 I needed to adjust the outdoor reset curve up so the loop that serves the first floor wouldn't leav

I do think an air-to-water could make sense for us, though it wouldn't be able to handle the coldest days because our radiators aren't sized to keep the house warm at the lower water temperatures it puts out. The main problem is

Your link has: "Most bunion surgery is performed under ankle block anesthesia, in which your foot is numb, but you are awake. Occasionally, general or spinal anesthesia is used."

If you move somewhere to work at age 62 and then retire at 65, can you stay there? Do you have to become a citizen first? (Just curious; I know this is a tangent!)

In MA this actually does work at first glance: a 23% efficient Generac 7171 is rated for 9kW at full output on natural gas, and uses 127 ft3/hr (1.37 therms). This is $0.30/kWh at $2/therm, compared to the $0.323/kWh I p
