The first high-efficiency, commercial, gas-fired, hydronic boiler introduced in the US, AERCO's KC1000 natural gas and propane-fired boilers have been performance proven for more than 18 years -- longer than any similar product in the market. It is an ideal solution for multiple boiler or combination domestic water/space heating plants, and can be equipped, or retrofit, with AERCO's low NOx burner to minimize emissions in environmentally friendly installations. Importantly, this burner package can also support dual fuel (natural gas/propane) applications.

The condensing heat exchanger design is built to withstand thermal shock and eliminates the need for boiler pumping equipment to lower the size, cost, and operating expense of components throughout the entire heating loop. The forced draft, modulating burner operates with 20:1 turndown (natural gas) to deliver up to 95% thermal efficiency while simplifying the venting system.Click here for Efficiency Curves.
