Budget tight? Can't afford a brand new boiler? There is a cheaper way to cut your fuel bill: Retrofit an Economizer.
What is an Economizer?
It is a heat exchanger installed on your boiler's exhaust stack. It captures the waste heat that is about to leave the chimney and puts it back into your boiler water.
The Yudong 'Fin-Tube' Design
We use High-Frequency Welded Spiral Finned Tubes. These fins increase the surface area by 10x compared to bare tubes, maximizing heat capture.
