Cozy Heating Systems Space Heaters and Furnaces

Global Pro Tankless Supply is pleased to announce that we are now stocking Cozy Heating Systems line of space heaters, wall furnaces and floor furnaces. Cozy is a leading supplier of gas heating equipment known for their commitment to product excellence. Designed to withstand the test of time, Cozy heaters are engineered for long-term comfort and dependability. GPTS is here to introduce the following heaters and furnaces, now available for purchase through our website: Cozy Gravity Wall Furnaces, Cozy Vented Console Heaters, Cozy Direct Vent Wall Furnaces, Cozy Conventional Vent Counterflow Wall Furnaces, Cozy Direct-Vent Counterflow Wall Furnaces, Cozy Challenger Floor Furnaces, and Cozy Hi-Efficient Direct Vent Wall Furnaces

The Cozy Gravity Wall Furnaces include the natural gas models W255G, W355G, and W505G, and the liquid propane models W256G, W356G, and the W506G. Cozy Gravity Wall Furnaces mount on any inside or outside wall (single wall only), providing both circulated and radiant heat in an economical package. Available in single or dual wall models, each fits between any standard 16” center stud space. Available in 25,000, 35,000 and 50,000 BTU’s, Cozy Gravity Wall Furnaces provide ample heating for new constructions, additions, and other hard to heat areas.

The Cozy Vented Console Heaters include the natural gas models VC201 B/C, VC351 B/C, and the VC501 B/C (conversion kits are available for liquid propane use). Cozy’s Vented Console Heaters incorporate quality, efficiency and contemporary styling at an affordable price! Choosing the closed front console for pure circulated warmth at an even more economical price! The textured steel casing is coated with a baked black enamel painted finish that resists scratching and fading.

Each unit comes equipped with a 100% low-BTU safety pilot and top-operated temperature control with a pressure regulator for either natural or propane gas. Total safety is assured by a resettable vent spill safety device which cycles the unit off in the event of flue blockage or incorrect venting installation. An optional blower eliminates air stratification and distributes warm air throughout the room. These units require a BW vent (not included) to complete installation.

The Cozy Direct Vent Wall Furnaces include the natural gas models CDV155C, CDV255C, and CDV335C, and the liquid propane models CDV156C, CDV256C, and CDV336C. Cozy’s Direct-Vent Wall Furnace mounts on an outside wall and occupies minimal room space. The continuous seam-welded combustion chamber draws air from the outside and exhausts through a concentric vent system, which keeps the interior air warm and fresh. The louvered cabinet design maximizes airflow, providing uniform temperatures from floor to ceiling. A telescoping vent assembly is included and fits a standard 5”- 9” wall thickness, eliminating the need for expensive and difficult-to-install vent pipe systems.

The Cozy Conventional Vent Counterflow Wall Furnaces include the natural gas models CF403D and CF553D (conversion kits are available for liquid propane use). Cozy Top-Vent Counterflow Wall Furnaces can be mounted on any inside or outside wall, allowing maximum installation flexibility. The powerful, thermostatically controlled blower draws cool air into the upper grill and delivers warm air at floor level, distributing heat uniformly throughout the room.

The Cozy Direct-Vent Counterflow Wall Furnaces include the natural gas models DVCF403C and DVCF553C (conversion kits are available for liquid propane use). The combination of fan-forced efficiency, counterflow heat delivery and sealed combustion makes Cozy Direct-Vent Counterflow Wall Furnaces the perfect heater for multi-story units, room additions, garage apartments, vacation homes, and more.

The Cozy Challenger Floor Furnaces include the natural gas models 90N30A, 90N50A, and 90N65A (conversion kits are available for liquid propane use). The Cozy Challenger Floor Furnace provides warm, even heat through the natural convection of circulating warm air. Cozy’s scientific design ensures a high volume air exchange–as much as three to five times per hour–guaranteeing uniform temperatures throughout your home. The Cozy Challenger features a factory-mounted control with built-in pressure regulator and 100% safety pilot. The millivolt controls require no electricity to operate, so losing heat during a power failure is never an issue.

The Cozy Hi-Efficient Direct Vent Wall Furnaces include the natural gas models HEDV253A and HEDV403A (conversion kits are available for liquid propane use). Cozy High-Efficient Direct Vent Furnaces are a perfect heating solution for single-family residential, rental, vacation home, apartment, and below grade heating applications. They mount easily on any outside wall or, if vent extensions are used, on inside walls for central placement within the living space. The sealed combustion chamber draws air for combustion from outside and exhausts through a concentric vent-pipe system to the outside – retaining heat and maintaining interior air quality.

Low Stock on Bosch 450 ESR NG (Natural Gas)

Global Pro Tankless Supply is just about out of stock on the Bosch 450ESR NG recirculating heater. The 120,000 BTU Bosch Protankless 450 ESR NG Tankless Recirculating Water Heater is temperature modulated and has an electronic ignition. Theis recirculating water heater is designed and approved for heating and recirculating potable water in conjunction with an indirect tank. The 450ESR recirculating water heater is not approved or designed for closed loop heating applications.

The Bosch 450ESR unit is not a traditional tankless water heater. It has no flow switch to respond to water flow. Instead it is a recirculating water heates designed for tank loading applications. When an aquastat (not included) hooked up to a tank tells the ESR that water needs to be brought back up to temperature, the ESR will tell a circulator (not included) to turn on to create flow through the heater to reheat the water in the tank.
Please call Global Pro Tankless Supply at 866-289-4652 while supplies last.

Obsolete Bosch 125BO NG (Natural Gas) Outdoor Tankless Water Heater

Global Protankless Supply currently has 1 of the Bosch Aquastar 125BO NG outdoor tankless water heaters left in stock. The Bosch AquaStar 125 BO model has a pilot light and offers a Piezo push-button ignition and utilizes a modulating gas valve to ensure a constant temperature at varying flow rates. The 125BO is designed to be installed outdoors and has a 120V plug that is only used for freeze protection. The 125 BO is the perfect tankless solution for smaller families and households that only use no more than two hot water applications at a time.
The Bosch 125BO NG is a good replacement for the older GWH 425HNO NG also.  The 425HNO NG was basically the same unit but the 125BO has the standing pilot light and the 425HNO NG used the hydro ignition system.

Bosch has approved these four outdoor heaters for the following areas of the United States:

Florida, Georgia, North Carolina, South Carolina, Alabama, Mississippi, Arkansas, Texas, Virginia (only in zip codes beginning with the first three digits 233-237), Arizona (in zip codes beginning with the first three digits 850-857 and 864), Oregon (in zip codes beginning with the first three digits 970-975), Washington (in zip codes beginning with the first three digits 980-986), California (except in zip codes beginning with the first three digits 935 or 961).

Some people install these outdoor tankless water heaters for their summer homes or cabins in areas of the US and Canada that do freeze. When these heaters are installed in freezing locations the water heaters must be completely drained so that the heat exchanger and pipes do not burst. The Bosch warranty does not cover damage due to freezing.

The WebStone Isolation Valve Kits really make the task of draining these outdoor tankless water heaters easy, so they are especially recommended for this application.

Please call Global Protankless Supply at 866-289-4652 for further questions or to order.

Bosch Greenstar Boilers Installed at Elevation

The Bosch Greenstar Floor-Standing (FS) and Wall-Hung (WH) straight boilers and combi boilers are affected by higher elevations and thin air.  Input and output rates are reduced at higher altitudes due to thin air with reduced oxygen levels.  Some of the FS and WH units have a couple different fan speed adjustments that may help with the elevation.  Basically the Bosch Greenstar boilers will lose 3% for every 1000 ft of elevation.  No adjustment is needed up to 2,000' sea level.

The Larger Bosch Greenstar 151,000 BTU boilers both FS and WH units will not be effected by the fan speed adjustments and will be derated at 3% for every 1000 ft elevation.

All of the rest of the FS and WH straight boilers and combi boilers (57K BTU - 131K BTU) offer altitude adjustment which compensates for the effects of thin air, and are therefore NOT derated up to 6000 feet (1829 m). Above 6000 feet (1829 m) a rate of 3 % per 1000 feet (305 m) applies.  Please see the chart below and the fan speeds for adjustment.
