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.

New Bosch Hydronic Air Handler

Global ProTankless Supply is pleased to announce that we are now selling the new Bosch Air Handler Systems.  These systems are designed to be used in conjunction with the Bosch Greentherm C1050ES & C950ES units.  The new Bosch Hydronic Air Handler can replace furnaces with a ducted system, eliminating the need for a gas pipe, venting, and fresh air in-take required for furnaces. The new air handler has an integrated control board that connects to the home’s thermostat. When the thermostat calls for heat, the air handler will turn on the integrated pump immediately and turn on the fan 30 seconds later to allow the heat exchanger to preheat. When the thermostat calls for cooling, the control board will only activate the blower.

The air handler connects seamlessly with tankless water heaters, transferring the highly efficient water heater’s hot water through a hydronic heating coil within the air handler. As the hot water circulates through the coil, warm air is sent through the residential duct system as the cool water by-product recirculates to the tankless unit to be reheated and reused.
The air handler is available in two models, AHU 50 and AHU 70, which can be sized with most CFM and BTU output ratings to suit a range of home sizes.

The Bosch Hydronic Air Handler is designed to work efficiently with the ENERGY STAR rated Bosch Greentherm tankless water heater to provide a complete solution for home heat and domestic hot water.

The hydronic air handler can also be used with A/C systems - a compatible A/C coil can be placed on top of the hydronic air handler and the blower inside of the hydronic air handler turns ON when the thermostat calls for cooling.

For further information and to purchase a Bosch Air Handler please call Global ProTankless Supply at 866-289-4652.

Bosch Greenstar Boilers Now Come With CRC200 Comfort Room Controller

All of the Bosch Greenstar Wall-Hung and Floor-Standing boilers now come with the CRC200 Comfort Room Controller.  The Wall-Hung Greenstar boilers used to come with the FW200 Weather Compensating Controller but that is now sold as an accessory.

The CRC200 is a programmable controller with an integrated temperature sensor and can be used as a boiler control or in conjunction with the CZM100 Comfort Zone Manager as a room controller. It comes with back light and features a time program for heating and indirect hot water tank.
The user interface is used to control a heating zone and a Domestic Hot Water (DHW) tank charging circuit for water heating directly at the heat source. The user interface displays information about the heat source and heating system and is used to change the settings.

A maximum of 8 heating zones is permitted when connected to several CZM100 Comfort Zone Managers. Water heating may be controlled with or without time program. Installation options: On the wall with a BUS connection to a heat source or CZM100 module with an EMS-BUS Interface (Energy Management System).
