Description for Lochinvar CBL315M-9

Copper-Fin gas-fired boilers are high-efficiency boilers that save space, save money, are lightweight, and are simple to service and install. Copper-Fin boilers are equipped with a built-in draft hood, a highly efficient copper tube heat exchanger, specially designed two-stage electronic control system, and they are approved for installation on combustible floors.

The boiler's two-stage electronic temperature control provides flexibility and saves fuel by closely matching heat output to system demand. On colder days the boiler fires at full output, and in warmer conditions the boiler reduces heat output to save energy and reduce boiler cycling. During the majority of the heating season, less than full boiler output is required to satisfy the heat load. For this reason, Lochinvar has developed a two-stage firing system. Two-stage firing, standard equipment on all Copper-Fin boilers, provides dramatic fuel savings by reducing the firing rate 50%. And the two-stage firing control is ideal for applications utilizing outdoor reset. (Outdoor reset is available as an option.)

The heart of the Copper-Fin boiler is its copper finned tube heat exchanger. With this unique gasketless design, the best of both worlds are combined: cast iron headers for long-lasting durability, and a copper finned-tube heat exchanger for high efficiencies and fast heat transfer. The gasketless heat exchanger design reduces the risk of leaks or system failures that are common with conventional boilers. Plus, the unit's low-mass design means that water gets heated quickly. Not only is heat up time nearly instantaneous with these boilers, the energy consumption and operating costs are lower too.
