How Ray is the right fuel efficient boiler for homes with radiant heat
Radiant heating is increasingly popular in today's homes, and being highly fuel efficient is just part of its success. The other is comfort: radiant heat gives a home steady, even, comfortable heat—a quality that plays right into the strengths of Ray's cast iron engineering. By retaining heat evenly over time, and through digitally-controlled fuel usage to maintain temperatures, Ray brings uses time-tested cast iron to put a new twist on fuel efficient boiler performance for homes with radiant heat.

How the Ray boiler and radiant heat make a home more fuel efficient
One of the reasons radiant heat boiler sytems can be so fuel efficient and comfortable is that they heat the objects in a home (the floor, the furniure touching the floor, etc.) rather than just the air. That way, things in the home stay warm, so the boiler uses less fuel to warm them up later. Encasing the radiant heat pipes in concrete beneath the home's floor helps maintain this warm base for to be even more fuel efficient: this is called "thermal mass." Because the Ray boiler's cast iron core is so much more substantial than an aluminum-based boiler, it boosts the radiant heat system's thermal mass that much more, making it more fuel efficient.

How a fuel efficient boiler keeps the air clean as a low NOx appliance
It's great for a home to spend less money by having a fuel efficient boiler. But what makes home owners feel even better is to know they are minimizing emissions by choosing a low NOx boiler. Not every fuel efficient boiler is a low NOx boiler, but Ray is. In addition to its 92.7% AFUE fuel efficient rating, it is certified to SCAQMD standards as a low NOx boiler, with less than 30 ppm. With the fuel efficient, low NOx Ray boiler, yellow is the new green!

How Ray is different from any other low NOx fuel efficent boiler
What makes the Ray boiler is different from any other low NOx fuel efficent boiler lies in its SmartCycle digital control. A custom built control tuned to Ray's exact engineering, SmartCycle has monitoring capabilities that carefully regulate fuel usage to make it a boiler that finds the most fuel efficient patterns for how it's used in each household. This careful fuel usage also makes it a low NOx boiler. SmartCycle can watch how temperatures change as it runs and predict when to turn off: it's the brains that make Ray a low NOx boiler that's becomes more fuel efficient the more time it's operating in each individual home.

Ray is uniquely well-designed for boiler replacements
Ray fits into existing heating systems more easily and with more benefits than any other boiler. It works with any closed loop system configuration: cast-iron radiators, fin-tube baseboard, radiant heat, fan coils, or a mix of any of these. No matter the set up, there's no need to change the existing pumps or controls, no need for additional expensive add-ons. Best of all, Ray’s built-in SmartCycle control will maximize energy savings regardless of the type of thermostat already in place.
