Oct 09, 2018 · Advantages and Disadvantages of Biomass Boilers. With the constant rise in prices of oil and fossil fuels, many people have started to look for alternative ways of heating their homes and businesses. One of the options that is gaining popularity is an investment in wood pellet or wood chip boilers.

Biomass boilers are normally substantially bigger than their fossil fuel-burning brothers though, for a number of reasons. Firstly since they are burning wood pellets as opposed to gas, the boiler needs to be larger to hold the larger volume of fuel.

Boilers are often rated in Boiler Horsepower (BHP) rather than Btus per hour. One boiler horsepower is defined as the amount of energy it takes to convert 34.5 pounds of water to steam in one hour at 212 degrees Fahrenheit. A boiler HP equals 33,472 Btu/hour.

Installing a buffer vessel is essential, unless there is a minimum constant load of around 30%, as most biomass boilers have turn-down ratios of between 2:1 and 3.5:1.4 Biomass boilers cannot operate effectively with short cycling periods. This can have a very dramatic affect on overall boiler thermal efficiency – much more than for a gas boiler.

Biomass boilers can work as a straight replacement for existing system or combi boilers. They are pretty efficient, and can be controlled in the way you’d expect with thermostats and timers. They are a little big bigger that those other designs, though, so you’ll need to be sure that you’ve got the space to put them in before you buy one.
