Are the systems protected from freezing temperatures?
In all situations, pipes are well insulated from the external temperatures. If in the very rare occasion water in the pipes approaches freezing it is pumped out and replaced with warmer water from the tank. Both pumped and compact systems use a closed circuit heating coil where freeze resistant liquid heats the domestic tank water. In the pool heating system, the controller is able to detect when water in the panel approaches freezing and replaces this with warmer water from the pool. Panels are also able to be drained down into the pool completely during the coldest weeks of winter as a precaution against freezing. Solar photovoltaics are not affected by freezing temperatures.
