A winter freeze shut down my tiny house toilet system
The bacteria in the toilet died in the cold, creating a health hazard. I learned they need warmth to work and put insulation around the unit. A heat mat with a thermostat keeps it going now. Avoid my error and prepare for cold snaps.
Been there... wrapped my whole composting unit in that silver pipe wrap one brutal year. A basic heat mat is a game changer, but make sure yours is secured flat against the tank. I learned the hard way that an air gap makes it useless. Old towels or a heavy moving blanket over everything adds another cheap layer.
