Bosch Greenstar 100 Wall Mounted Boiler Model ZBR28-3

DESCRIPTION

Greenstar is ideal for providing comfortable heating for small apartments, condominiums and single family homes within the 100,800 maximum input BTU rating. Special insulation offers ultra quiet operation perfect for radiant heating with panel radiators, in floor radiant, or baseboards. Radiant heat, like the sun, warms objects rather than just the air, creating a greater sense of warmth and at lower room temperatures.

Bosch has been producing products since 1886. We first produced water heaters and boilers in 1895. Since 2001 more than 2 million units have been installed worldwide. The 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.

Product Features & Applications

• Boiler setup with separate circuits for heating and a DHW tank
• Ideal replacement solution where the existing DHW source will stay in place
• Perfect for systems with a very high DHW demand as the tank can be matched to the hot water requirement without necessarily having to increase the boiler output
• For use with renewables like solar thermal to reduce the energy consumption even further
