Replacement Solar Hot Water Circulating Pumps For Flat Plate & Evacuated Tube systems
Over the years and especially during the Australian Solar Power "rebate boom" thousands of home owners took advantage of the generous State & Federal Solar Hot Water Rebates called REC's , STC's or VEEC's and installed a solar hot water system. Traditional flat plates or the newer technology evacuated tube systems where installed by numerous companies many now are no longer in business which can make maintenance on your system a little harder. These systems typically consist of a "split" arrangement where the tank is located at ground level and the "collectors" or "solar array" are mounted flat or pitched on the roof above. plumbonline have a wide selection of solar hot water replacement parts to keep your system in tip top condition.

To transfer the solar heated water from the collectors to the tank various circulating pumps and controllers where used in the industry, some of the more popular brands are; Grundfos, Wilo, Dab, Bianco & Salmson to name a few. Over the last ten years most systems have been sold with the the industry leader - Grundfos Brand as the hot water circulator. (plumbonline are an authorised Grundfos Pump Distributor selling domestic & commercial/industrial pumps.)
The common Grundfos models are the 15-14B now called the 15-14 B PM or Comfort pump and the model of choice the Grundfos 15-20 CIL 2.
