Solar Circulation Pumps
The solar circulation pump is the heart of our solar systems.
When the temperature of the fluid in the solar collector becomes 6 degrees higher than that in the water to be heated the solar controller starts the solar pump.
The solar pump circulates the warmed water so the heat is transferred into the cylinder or heat exchanger.
The pumps we use are the highest quality available they are subjected to high temperatures and are frequently stopped and started.
Many of our domestic systems use a solar PV powered pump and controller and provide a 100% solar solution with no connection to mains electricity. 
Larger and more complex installations require larger pumps and a 240 volt supply which makes the use of a Photovoltaic powered system less viable.
On larger installations we commonly install two pumps per system with stagered start up temperature differentials, ensuring that when extra heat is available it is transfered at a faster flow rate.
