Using Savastat LC With Zone Optimizers

Can Savastat LC be implemented in conjunction with Zone Optimizers?

Yes, however since the zone optimizer will be cutting hot water supply off to various zones as programmed into the unit, reduced savings will be achieved.

We have conducted numerous case studies in facilities which incorporate zone optimizers, and have found the typical savings still achieved to be in the 8% to 10% range.  This is still fairly decent savings, however the return on investment will be somewhat longer.  If fuel consumption for the facility is at least $15k per year, and a sinigle boiler is providing the hot water heat, the unit will still cost justify itself quite easily, and should achieve an ROI of under 2 years.  If multiple boilers are used, adjust the consumption accordingly.  Thus, if two boilers are employed, annual fuel spend of $30k will cost justify easily, and in most cases provide a payback of under 2 years.

Most organizations will find savings in this range to be satisfactory to move forward with Savastat LC implementations in these applications.
