Using your Sun-Mar composting toilet in winter

When cottage season winds down and people start preparing for winter, our sales and service departments are frequently asked, “Can my Sun-Mar toilet be used over the winter?”

With toilets installed across North America, this is an important question for new and occasional users to Sun-Mar toilets. Our self-contained toilets, such as the GTG, the Excel and the Compact, and our Central systems like the CENTREX 2000 or CENTREX 3000, can be easily used in the winter, usually with only minimal changes to how they are installed.

The short answer is, yes, all of our toilets can be used in the winter. With that being said, there are some points to consider.

Temperature

With winter comes the cold weather, and changes in temperature can affect your compost in strange ways. For example, if the self-contained or CENTREX series toilet is installed in a location with temperatures consistently below 50° F / 15° C, the compost in the drum will go dormant and composting will stop.

If your toilet will be used in the winter, there are a few more steps to making sure your toilet functions properly. Things like insulating certain components, installing a heat source near the composter, and removing compost from the drum to make room for new material will keep your composter in top condition.

Our customer service department is always happy to go over your particular installation, and advise how best to proceed for a hassle-free transition into the colder months ahead.
