Understanding Different Designs of Solar Water Heaters

Defining a Solar Water Heating System –

Solar water heaters are considered as the right alternative for water heating in residential premises. If you’re looking to use a solar water heater in the Northern climates, it requires some sorts of protection against freezing. It can be done by means of a drain back where the water drains back into the house during the night to protect against freezing. 

Otherwise, it can be done through an active closed loop with a heat exchanger that helps in transferring polypropylene heating fluid to the potable hot water. Hence, polypropylene can be chosen in the cold northern climates to handle the temperature below minus 40. As a result, the system won’t freeze and get damaged even if any malfunction occurs.
