Harman PB105 Biomass Pellet Boiler As Well As Dwelling Heating Solutions
The Harman Stove are one of the industry leads in the US for biomass pellet stoves, however they have we not a key player in the wood pellet boiler market. On the other hand Harman have now developed the PB105 wood pellet boiler. The PB105 shares many of the same features as the award winning Harman pellet stoves. These features include automatic heat control and automatic ignition, burn pot plus also automated pellet pro feeder. Good access to the burn pot is an additional benefit, access to the in built hopper is also convenient, by a hopper storage capacity of 205lbs, which is accompanied with a large ash bin. All these features mean the PB105 will be a more fuel flexible as well as reliable biomass pellet boiler. The maximum warmth out of the boiler is just below 14 million Btu’s. This means the unit can provide heat for a space of 2,500 sq.ft, and has a incineration plus heat recovery efficiency of 85% which is also very impressive.
The PB105 uses a 4 inch vent and also has a three stage heat exchanger to capture as much warmth as likely. The unit has a viewing window into the combustion chamber which is also the access point for the burn pot. The wood pellet boiler also has an insulated water jacket to lessen warmth loss. The units operates on 120v and has a fuse rating of 6A. To meet fire safety regulations the pellet boiler must be clearance around the back of the boiler of 6 inches, with 20 inches of clearance on both sides of the PB105, in addition to 36 inches at the front. There are a mixture of additional options extras that can be fitted. These include an outside air heat sensor, which can be very useful to investigate the efficiency of residence lagging, as well as also view the load on the boiler. Boiler pressure gauge and pressure relief values should be options to choose. Additional options include water temperature gauge plus boiler water drain off value. The PB105 is designed well, but time will tell if Harman will dominate the US wood pellet boiler market the same way they currently dominate pellet stoves.
From the appearance of pellet fuel, pretty much all types of pellet look the same. Other than slight changes in colour, owing to the manufacture process the pellets have the same size, shape as well as density. This means pretty much any pellet can be install a hopper in any pellet stove or pellet boiler, plus the pellets will be fed into the burn pot. On the other hand, here is where the similarity ends, as because of the pellet construction process makes dissimilar biomass fuels appear the same, their combustion characteristics are very very dissimilar. For case in point, all pellet stoves along with boiler are primarily designed to burn premium pellets, which produce an ash content of 0.5%. On the other hand dissimilar types of wood fuel may make an ash content from 1% up to around 7%, as well as increased ash content is not the only difference. Some pellet fuels produce ash which melts at lower temperatures, for example straw pellets. Melting ash forms into a matter called a clinker. Even wood pellets can actually form clinkers because of the intense heat that a pellet fire can generate. Some pellet stoves and boilers cannot deal by way of clinkers.
