SOLAR PUMP 15-20 CIL2 with pump unions gives you a pump ready to install on your solar hot water system. 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

This pump comes highly recommended by many plumbers for solar heating with evacuated tubes. It is working well so far. It was annoying that it didn't come with the necessary attachments to connect it straight in and my plumber had to stop work and go and get these things. In the öld"days they did come with the necessary attachment devices.
This pump was great because the first one I bought lasted at least 4 years of punishing temps.
silent operation, replaced like for like after 6 years (which i suspect got shorted as i did not cover correctly in wet weather).
excellent replacement pump and amazing service
As of 5/11 /18 working
Ordered this pump, it was delivered the very next day and the install was an absolute breeze! Would also recommend checking your high temperature non return valve as advised by plumbonline as mine was completely gone and obviously the cause of the failure. Great service and advice would highly recommend!
Service was second to none. Ordered this pump on Thursday arrived am Monday to Newcastle NSW. Outstanding. I have used Grundfos pumps in my solar system before but this model seems to be quieter and better suited to my system. Time will tell. Thanks Plumbonline.
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.
I was looking for a replacement pump for my solar hot water system. I found the 15-20 CIL here on plumbonline for a great price, one quick call to their helpline and it was delivered next day! I would recommend plumbonline and the Grundfos pump.
