Our ultra high efficiency, ultra low NOx boiler is designed with the LEED® certified professional in
mind. Every unit comes with a built-in, pre-plumbed cold water run system that prevents condensation damage to the primary heat exchanger. Our hybrid design allows condensation to form only in
the pre-plumbed and piped stainless steel secondary heat exchanger. This complete system is
contained inside our rugged, powder coated cabinet that takes up less than 11 ft2 of floor space. Take
advantage of our built-in freeze protection that can save you thousands on venting material by
allowing you to install the boiler outdoors. Gain greater energy savings with our microprocessor controlled VSP with 10: 1 turndown capability. The firing rate is seamlessly controlled by our EMS
friendly 0-10VDC direct drive input control allowing for a smooth 4: 1 turndown rate. With our 2-line
20-character, real English display, diagnostics and system status are easily understood.
Now with PVC venting option!
