Bosch Thermotechnology has introduced two new gas condensing Greenstar models for residential applications with AFUE rating of 95%: the Greenstar Combi 131 for space heating and hot water at up to 3.2 GPM and the Greenstar 79 for space heating.
Both wall-mounted units are available with new venting options from Bosch: concentric up and out venting and polypropylene twin pipe for installation flexibility. The up and out venting option kit consists of an appliance adaptor, a 90° elbow and a telescopic termination that accommodates varying wall thicknesses.
Greenstar wall-mounted boilers feature ultra-efficient condensing technology. With a hydronic manifold and three-speed integral pump, they can be installed more quickly.
With the addition of these two models Bosch Thermotechnology’s Greenstar boiler family consists of five regular space heating boilers and three combi units under 155 MBH for residential applications. All Greenstar products come with a limited lifetime heat exchanger warranty and a limited 5-year parts and labor warranty (see www.boschheatingandcooling.com for complete warranty details). Greenstar 131 Combi model is available in September; 79 boiler model will be available later this year.
