Those in need of biomass boiler for their home may adhere to the following tips for genuine investment:
Type – Supplying biomass heating through boilers is usually available through their fuel types. Usually the biomass boilers are classified as log gasification, wood chip and wood pellet fuelled boilers. Each type of biomass boiler is associated with its own advantages and disadvantages. Their costs and operating systems differ. Fuel as well as maintenance costs may also vary. Households using the heat loads of 10kW to 45kW generally use pellet boilers. These installations are automated and compact. They generally resemble to a fossil fuel system. They facilitate lower running costs as compared to oil or LPG. Another benefit of such boilers is zero net carbon footprints. They prove a great benefit for the users.
Space – Sufficient space must be there before buying any biomass boiler for your home. Pellet boilers can be installed inside your home.
Manufacturer – Buying biomass boilers from prominent manufacturers is good. They must have gained reputation by fulfilling the boiler requirements of the customers to their entire satisfaction.
Automatic Features – Usually the pellet boilers are equipped with automation ignition systems.
Combustion chamber ash – The quantum of ash produced in the biomass boilers needs to be removed from the combustion chambers. Such ash needs o be swept or vacuumed for efficiency purpose. Building up of ash may result in dropping the efficiency levels. Units with automated mechanism for removing ash after frequent intervals are treated as most efficient.
Heat exchanger cleaning – Efficiency of the biomass boiler may go down if the heat exchanger surfaces become coated with layer of fine fly ash. Units with manual operated lever are usually available for domestic purposes. Motorized cleaning controlled units are also provided by many manufacturers that are engaged in supplying biomass heating systems.
Automatic ash removal – Prominent companies facilitate boilers with an auger screw for extracting the ash into a larger ash container. The same may be needed to get emptied once or twice a year.
Re-fuelling: Small pellet boilers are generally available with fuel store in one single unit. This could be usually of 40kg capacity hopper that may run for few days. Larger boilers may be equipped with 150 kg capacity as far as refueling is concerned. The bulk store is filled by using two solid pipes with special type of connectors that are built into the store. Use of pellet delivery truck is made for connecting them and blows the fuel into the store. The delivery method resembles with that of the oil delivery. The fuel storage space can be reduced with the available space or depending upon the budget.
Convenience of controls – The choice of biomass boiler depends much upon the controls that must be easy to operate. It is recommended to avoid re-plumbing a set-up that is in working condition and installed in the recent past. Specialist controls may be got installed to get maximum efficiency from the boiler. The installer must guide you how to use them.
