FEATURES

bullet

An economical investment in home comfort, this compact, high efficiency series is loaded that features that spell satisfaction for both homeowners and servicemen.

bullet

360 WET LEG DESIGN - The CWL's round design allows water to circulate completely around the combustion area with the exception of the base, getting the maximum heat exchange. This unique wet-wall unit is designed without a refractory combustion chamber.

bullet

Compact Size - Standing 29-1/2 inches high, the compact size and "0" clearance allow the CWL to be installed safely and easily in areas not approved for other boilers.

bullet

VERSATILE VENTING - The CWL can be vented straight up from the boiler or from the rear of the boiler with a simple change of the flue collector box. The boiler is a perfect design for the replacement of under-the-counter boilers, modular homes and mobile homes.

bullet

WATER CONTENT - The compact CWL has a 15-gallon water reservoir and a standard 5-gallon coil that assures ample hot water for the customer.

bullet

FORCED DRAFT BURNER - The forced draft burner eliminates chimney draft problems. The CWL-Series is designed to work in spite of poor draft conditions. It also seals products of combustion from the living area, reducing potential "puff-back" problems.

bullet

EFFICIENCY - 84% to 86% AFUE - The CWL boiler is IBR rated at three different firing rates. Extra nozzles and labels are included with each boiler. Listed with DOE Energy Star Program.

bullet

ASME CONSTRUCTED AND IBR RATED - Each boiler is constructed and hydrostatically tested in accordance with ASME Boiler Code. The capacity and efficiency are rated in accordance with the standards of the Institute of Boiler and Radiator Manufacturers (IBR).

bullet

LIFETIME LIMITED WARRANTY - Unlike other pro-rated warranties that often cover a small percentage of the cost of a new boiler after the 15th or 20th year, Thermo-Dynamics boiler replacement costs are never more than 50% of the replacement boiler list price.

STANDARD FEATURES 

bullet

Built in "Air Scoop" purges air from the system providing a quiet trouble free hot water heating system without the use of external devices.

bullet

Extended Flange Coil is away from the boiler for easy accessibility. The use of ribbed neck carriage bolts eliminates the problems encountered when a weld stud is broken during service. The large coil plate allows for a greater gasket sealing area.

bullet

Weld fittings extend beyond the jacket and allow the service technician or homeowner to see small leaks that, if undetected, could later damage the boiler shell and potentially void the warranty.

bullet

Easy cleaning and maintenance accessibility to combustion areas and the open tubes make it easy for the service technician to thoroughly clean the boiler. No tight, pin-type passage ways with "hidden nooks and crannies", making a thorough cleaning possible. A well-maintained boiler continues to perform at higher efficiency and is less likely to develop service problems.

bullet

OPTIONAL DIRECT VENT SERIES - Available for sidewall direct vent applications . No power ventor required.

bullet

Natural Gas and L.P Gas Models Available.
