Summary: Patented US10364979B2

An apparatus and method for recovery of waste heat in a boiler system, wherein heat from the low pressure steam in a feed water tank, which otherwise would be lost through dissipation, is used for other applications. Particularly, waste heat energy recovered in the form of low pressure steam can be used to heat make-up water for the boiler system.

Grundfos CR pumps

The world has changed in so many ways since Grundfos invented the world’s first
vertical multistage centrifugal inline pump back in 1972. But our drive to keep
moving the limits of the possible for our customers has always remained the same.

The Zestos boiler water feed tank was the best investment I ever made.

It displays the water temperature, and has a high performing pump.

The motor runs well and has been helping me save gas and water.

Zestos Tank I installed about a year ago and I am glad I did it runs my boilers very efficiently and I always have steam at high volumes and very energy efficient which brought down my utility cost also.

I'm the manager at Dry Clean X Press and after instaling the return tank from ZESTOS I don't have the recuring problems from my boilerblime befor and everything is running smoothly. This has been a great investment and we are very satisfied.

We are Modu food Service located in Vernon and recently, we’ve purchased and installed ZESTOS feed tank. With their advice we’ve also replaced our boiler with two smaller ones that provided enough steam for our needs, which saved us a lot on energy bill. So far our boilers run smoothly and very efficiently without any issue. Consulting/estimation/installation all went without an issue and we are very satisfied with the investment.

What nationalboard Say - FeedWater GuidelLnes

Oxygen in the presence of water cooler than 212°F can cause a
serious destructive activity called oxygen corrosion. The amount of oxygen absorbed
in water is proportional to temperature and pressure
