OK, We have hot water heat and of course running water. What steps do I take so the water lines are empty, and I don't need to heat the house
I'll take the water question...
Your smart for not wanting to pay for heat while you are gone. Some blow out the pipes, but I rigged up a pump to run RV antifreeze through my lines. I also put a bypass for the water heater (HWH)just like the RV.
I use the HWH to siphon out the water lines. Hook up a drain hose, open the HWH drain valve and open one faucet at a time until you hear gurgling. It will pull the water out of both the hot and cold side. Then I open a few to drain the HWH. Open the HWH bypass and close the inlet and outlet valves.
I then start the pump to push the AF through, and open one faucet at a time until I see red. Don't forget the washing machine, ice maker, etc. Dump some in all the drains, Also the washing machine and dishwasher, and run their pump to get AF in their drain pumps.
Don't know what to tell you about your boiler, I heat with wood, but have electric baseboard backup. I used to leave the heat at 50, blow out the pipes, but that didnt work for me. When it got real cold, I lost electricity, ever single year for eight years straight before I wised up. There was always a low spot in the pipes the water would accumilate, freeze and split. Last year it was the saddle valve for the ice maker that I didn't flush, and split.
