Header tank – Float Valve vs ‘Solar panel and solenoid’ header tank

Hi. I have a solar hot water system that uses the solar auto fill. It has never really worked properly. How easy is it to retrofit this header tank to my system? Mine is from xxx brand solar.
Thanks ben.

Hi Ben,

We have sold quite a few of our float valve systems to replace the solenoid/solar panel systems.

Assuming it is a 1/2″ BSP fitting, it is a straight changeover.

The only variables I am aware off is if the fitting is too deep in the main tank, if this is the case, it just requires a 1/2″-1/2″ coupler.

Our stainless steel tanks and float valve have a significantly longer lifespan and reliability. We have an original header tanks on our R&D system which is over five years old, still works perfectly.

Our systems have been engineered for minimal maintenance and long lifespan, hence we have stayed with a traditional float valve component after many months of comparisons and testing.
