Boiler Systems and Energy Savings | Weil-McLain

Outdoor air temperature reset and warm weather shutdown controls when applied correctly can result in significant energy savings making condensing boiler a viable solution. Neither the reset control nor the warm weather shutdown is applicable in the domestic hot water operation making the condensing boiler less effective.

Condensing water heaters Archives - A.O. Smith

Convinced of the enormous added value of condensing water heaters, A.O. Smith has been delivering condensing hot water solutions for many years now. By using the heat which is released in the process of burning gas for heating the water supply, almost all of the consumed energy can be applied in this process. This heat is transferred to the water via the heat exchanger.
