I have a 2021 Bambi 19CB with a tankless water heater. We're having a cold snap and it's currently snowing, hovering at freezing temps but expected to warm backup in a few days and I have plans to hit the road. Currently, the tanks are empty and I put insulation around the grey/black tank outlets outside the rig and towels around pipes of the toilet and sinks. What should I do to the tankless water heater outside to keep it from getting damaged?
I'm currently making it my home office so I'm working in it now and have the heater on low as well as a small space heater going. When I first came in this morning, the water heater display by the sink was reading "E1" but has since gone back to normal. Hopefully, there was no damage done overnight.
Any feedback welcomed!
