Hi, I'm new to the forum and have some design questions. Our cottage is in Quebec and has electricity. We use it all winter and want to avoid "winterizing" it by keeping the closed and insulated crawlspace (where the water is distributed) at 10C. However in the spring we are hit with freezing rain storms that can cuase power outages which put the cottage at risk of cooling off to below freezing.
The simpliest solution I could think of is eco-worthy tracking PV with a simple 48v 1000w electrical heater in the crawlspace. When the sun is available it would heat without control (i.e. always on). This would boost the temperature during the day and (hopefully) avoid it from dropping during the night when it wouldn't be powered. I'm thinking 4 high efficiency PVs on the tracker wired directly to the heater. My question...would this work or is there a better way?
I've investigated evacuated tubes but it gets complicated. PV driven heat pump might also work.
Thanks.
