HIGH EFFICIENCY WATER HEATING AND HYDRONIC BOILER SYSTEMS

Family of PRODUCTS

With HOT Controls by Hamilton Engineering Co., Inc.

CUSTOM DESIGNED. PRE-ASSEMBLED. 24/7/365 SUPPORT.Hamilton Engineering has been providing the highest quality water heaters and hydronic boilers, along with the best service, for more than 30 years.

Using our patented technology, we engineer hot water and hydronic boiler systems that are more efficient and higher performing than most other products on the market today. Our EVO line is a great example: with operating efficiencies up to 99.8%, the EVO stands alone among high-efficiency condensing water heaters and boilers.

In the EVO condensing system, the products of combustion (some to all of the wet (latent) heat and all of the dry (sensible) heat) are forced to pass over the portion of the heat exchanger where the coolest water enters the system. At this point, the flue gases condense, releasing trapped heat that is then absorbed into the water through the heat exchanger. Condensate (water) and low temperature flue gases are left behind. The flue gases are so cool, in fact, they can be vented through PVC if desired. See technical data sheet for more detailed information.

HIGH EFFICIENCY WATER HEATING AND HYDRONIC BOILER SYSTEMS

Family of PRODUCTS

With HOT Controls by Hamilton Engineering Co., Inc.

CUSTOM DESIGNED. PRE-ASSEMBLED. 24/7/365 SUPPORT.Hamilton Engineering has been providing the highest quality water heaters and hydronic boilers, along with the best service, for more than 30 years.

Using our patented technology, we engineer hot water and hydronic boiler systems that are more efficient and higher performing than most other products on the market today. Our EVO line is a great example: with operating efficiencies up to 99.8%, the EVO stands alone among high-efficiency condensing water heaters and boilers.

In the EVO condensing system, the products of combustion (some to all of the wet (latent) heat and all of the dry (sensible) heat) are forced to pass over the portion of the heat exchanger where the coolest water enters the system. At this point, the flue gases condense, releasing trapped heat that is then absorbed into the water through the heat exchanger. Condensate (water) and low temperature flue gases are left behind. The flue gases are so cool, in fact, they can be vented through PVC if desired. See technical data sheet for more detailed information.
