Before purchasing this pump, you need to consider the age of the system and the availability of the full range of replacement component options for you system. Some solar hot water controllers that have been used with this pump in pump stations are no longer able to be purchased. Some applications may not be suitable for this pump now.              

The complete pump station, with the Grundfos 15-20 CIL 2 Circulating Pump, new roof and tank sensors, valves and a controller with a digital display, may be a better and more suitable replacement. The pump station provides full protection to the products inside. The advantage of using a pump station is that you replace everything at once. This is often a considerably less expensive option then trying to replace individual parts over time. If you are only replacing the pump, you need to ask 'why it has failed?' The most likely answer is because a component(s) has a fault, which has resulted in failed circulation. Additionally, you may find that over time other components you may need, once you have replaced the pump, are no longer be available. If you are simply replacing the pump, you need to check the roof sensor and controller before installation. Depending on the outcome you may need to consider your options.
