Laars D-MAX 165 Direct Vent Low Mass Counter Flow Oil Boiler

The MAX is the closest thing to heating perfection on the market today. MAXimum efficiency and MAXimum convenience of installation and service ensure you will never use another boiler again.

Minimum water + maximum heat transfer = maximum efficiency.

The series counter flow design of the MAX vessel enables the water to travel in series between the two chambers, with the cool return water seeing the cooler flue gases and then, once preheated, traveling into the inner jacket to meet the hottest flue gases. Coupled with the fact that the MAX does not have refractory material in the combustion chamber, MAXimum heat transfer is guaranteed.
