BOILER STACK ECONOMIZER | Maximizer
Our boiler stack economizer system will allow you to heat process water up to 140° F by utilizing the waste energy normally lost to atmosphere in your boiler stack exhaust. This system can be installed using a plate and frame heat exchanger to provide potable water. Watch our animated video to learn how Boiler Stack Economizers work.

Comparing Indirect vs Direct hot water systems
Explaining direct and indirect fired units Direct fired units such as Dorchester water heaters for hot water generation have an integral gas or oil burner that directly heats the water in its storage cylinder by supplying hot gases through one or more of its heat exchanger fire tubes within the cylinder which then transfers heat to the surrounding water.

It is called a "direct contact" system as the water being heated in the FLU-ACE directly contacts the hot gas leaving the boiler (or other process exhaust). This provides the absolute optimal heat recovery and is much more efficient than an indirect contact heat exchanger, which heats water which is in a tube by passing the exhaust gas outside of the tube (much like a typical boiler feedwater economizer).
