Below is a system we built for a correctional facility that has terrible water quality. We built the system with an RBI Futera Fll FW750 and a digital readout so they can monitor the heaters input and the secondary heat ex-changers output. They were able to install this themselves keeping their installation costs to a minimum.





The system below ECWS installed onsite to a RBI CW1000. Their water quality was approximately 22 grains of hardness so now being able to flush the secondary they have saved the water heater from damage.
