Description for Bosch ZWB-42-3

Note: Product Title reflects this boiler's IBR Net Output Rating.

Combi 100 Gas-Fired Wall-Hung Condensing Boiler provides Space Heating and handles Domestic Hot Water (DHW) with up to 98.7% efficiency and 34.6 to 100.6 MBH inputs! The new Bosch Greenstar condensing boiler line is engineered to offer the ideal solution for residential heating and hot water needs at an affordable price, without compromising quality or fuel economy.

Combi 100 series use a combustion process which achieves up to 98.7% efficiency and reduces NOx emissions ahead of 2012 SCAQMD (14ng/j) regulations, providing greater energy savings while contributing to cleaner air and better quality of life.

Al-Si heat exchanger
Each unit features an ASME approved Al-Si heat exchanger constructed of advanced Magnesium-Aluminum-Silicon alloy - offering increased flexibility versus traditional stainless steel. They are equipped with highly durable heating blocks that are corrosion resistant and designed to optimize clean burning combustion over an extra large surface area, which requires minimal servicing and reliance on spare parts during the boiler's lifetime.

FW200 weather compensation control
The included FW200 digital thermostat and outdoor reset boiler control acts as the nerve center of a home's heating system. Programmable up to six switching times throughout the day, this interface can be installed within the appliance or be wall mounted in any location throughout the home.

Heatronic III control
Bosch Heatronic III, a device integrated into the base of the boiler, provides instant access to the hot water and heating controls. Optional system controls are accessible, while instant feedback to the end-user along with a built-in diagnostics module effortlessly pinpoints operational issues. The exclusive keypad safety lock feature prevents unwanted tampering with the controls.

Plated stainless steel heat exchanger
All Greenstar Combi boilers are equipped with a high-strength stainless steel secondary exchanger and burner with double passage - ensuring consistent temperature output based on demand. The DHW hot water temperature control limit of 140 Degrees F helps prevent scale build-up within the heat exchanger.

Full modulating fan assembly
A full modulating fan automatically increases or decreases its speed according to the amount of gas coming into the boiler depending on the heat demand. This process, called modulation, prevents the boiler from either having too little or too much air in the unit for optimal combustion - ensuring high efficiency.

3 Speed Grundfos Integrated Pump
All Bosch Greenstar Boilers include the 3 Speed Grundfos Integrated Pump.

PLEASE NOTE: The product weighs 100.2 lbs. and may require the use of a
