FAQ


(1). How do I protect my solar system during subzero temperatures?


If you have a system that is operating in areas with subzero temperatures then freeze protection must be implemented.


The easiest means of preventing freezing is to use a controller with a low temperatures setting.


So when the manifold temperature drops below a certain pre-set temperature (5°C/40°F), the pump will circulate, warming the collector with water from the bottom of the storage tank.


The pump will not run continually, just periodically, the frequency of which will depend on the outside temperature.


In extremely cold areas, a closed loop using a glycol/water mix may be appropriate.

(2). Will water be heated on a cloudy day?


Yes.


Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating.


If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature.


This system will be automated so you don't have to worry about running out of hot water on a rainy day.
