    i built a big box that i insulated and is big enough for the ro to fit in. between uses i store the ro in the box with a 100 watt bulb for heat. no problems so far and we have had weather in the teens at night

    Mine is in an insulated closet.
    A small ceramic space heater does the trick.

    Draining the system and leaving it a day or two probably wouldn’t hurt, but you don’t want the membranes to dry out.

    Even if you are draining the unit I would assume the membrane will retain water and freeze. Just a thought.

    We have a CDL 250 which is advertised as not requiring a heated room. It is 4 years old now. After loosing the primary pump, multiple rebuild primary pumps, and finally a new primary pump (the Dealer was awesome and the only charge we have incurred is one rebuilt and one primary pump). The new recommendation is to use some type of small heat source to help reduce ice issues. We have our RO sitting on top of a tank. We use a heat lamp with cheap metal shade facing the pump area. It has worked like a champ since. We drain the unit by tilting it in several directions, but for the small electrical cost the heat lamp is worth it. We did place Thermax over the top on the 7' high ceiling and then used a couple pieces to come down on the sides to slow the migration of the heat.
