solar | water | heating | electronics | shoppingFor all but the simplest
solar water heating system, a
pump controller is a vital component. A solar water heating pump controller constantly measures the temperature of the solar panel (aka
solar collector), and the stored hot water tank (aka
hot water cylinder) to decide whether the pump should be on. If the panel is hotter than the tank then the cooler water is pumped through the panel to be heated up. If the hot water tank is hotter than the panel, then the pump is turned off so that the stored hot water is not cooled in the panel.
If a simple reliable and economical solar water pump controller is required then we of course recommend our own
Solar Water Pump Controller still available for just
£25.99. However, if a more complex controller is required with a graphical display, automatic frost protection, automatic backup heating from a conventional boiler, and more, then the
Drayton SHR52120 is an excellent unit to consider.
