Grundfos SOLAR PUMP 15-20 CIL2 Open Loop Solar Hot Water Pump 240V
An excellent replacement.
Posted by Jan Dallas on 23rd Dec 2015
My last two pumps lasted 18 months and 2 years. The original, a Grundfos, lasted over 6 years. The new one is clearly better made, yet lighter, much quieter and also much cheaper than the Bxxxxo pump I had before. I'm impressed so far, but time will tell. It has been installed for about 2 weeks so far.

Ordered the pump on a Thursday afternoon, was delivered to my door on the Central Coast NSW by 9am on Friday morning. 10 mins to install and now all working fine. Great service and would recommend.

The 15-20 CIL is optimised for domestic Open Loop solar systems both in terms of performance and choice of materials. For instance, the pump is able to resist a higher level of chloride than normal pumps.
The 15-20 CIL2 can be used as a replacement pump* for all open loop solar systems, both flat plate & evacuated tube types from all major manufacturers. We have listed the major manufacturers below to eliminate some of the guess work as there are hundreds of systems and models.
If the manufactures requires a set flow rate we have solar rated flow meter 15mm 1-2.5L/min or flow meter 15mm 3-8L/min, its also a good idea to replace the non return valve with a SOLAR Rated non return valve. Most manufactures require the non return valve to protect the circulating pump.
* some pipework modification might be required

The Grundfos 15-20 CIL 2's are commonly used as a replacement pump in an pre existing Solar Hot Water System, the existing power cord would be reused, avoiding additional time and electricians expense. If the pump is replacement is "like for like" then the existing unions would be used. If you are replacing an existing solar hot water pump please be aware that your plumber should check the installation & function of the high temperature non return valve, this valves omittance and or failure contributes to early pump failure.
