Unlike a furnace that heats and distributes air, a boiler heats and distributes water, sending it through pipes as steam to radiators, or as hot water to baseboard heaters, radiant floor systems, snowmelt systems, pool heaters or to a fan coil unit that then heats air. Boilers are typically fueled by gas or oil. Typical costs: Installing a standard boiler (80%-85% annual fuel utilization

The electrical efficiency is 52% (net AC, LHV), whereas that of the previous model was 46.5%.The previous system comprised two units: a power generation unit and a heat recovery unit. The latter unit contained the hot-water storage tank and the boiler. The new power generation unit contains the hot-water storage tank.

Understanding biomass boilers - Greenhouse Management

Feb 05, 2015 · Biomass boilers are steam or hot water generators that use alternative fuel (biomass) as opposed to petroleum fuels like natural gas, liquid propane and different kinds of oil. These biomass boilers have already gained significant traction in Europe, where greenhouse technology is often more progressive than what goes on stateside, according to Gene Zebley, renewable energy system sales for Hurst Boiler.
