They are ideal for Indian industries, commercial buildings, and institutions looking to shift from diesel, LPG, or electricity to a greener and more economical option.
What is a biomass hot water boiler?
A biomass fired hot water boiler burns solid biofuels such as wood, briquettes, pellets, rice husk, or agro-waste to heat water up to typically 85–95 °C for closed-loop heating systems. The unit includes a combustion chamber, heat exchanger, water jacket, insulation, and controls to deliver constant hot water at the required temperature and flow rate.
Fuel options and compatibility
These boilers support a wide range of locally available fuels including wood logs, wood chips, biomass briquettes, rice husk, sawdust, and other agro residues, depending on the grate and feeding design. Using regionally sourced biomass reduces dependence on imported fossil fuels and converts agricultural waste into a valuable energy resource.

Frequently Asked Questions
What fuels can I use in this boiler?
These boilers are highly versatile. You can use:
- Agro-Waste: Rice husk, mustard stalks, or groundnut shells.
- Wood Products: Sawdust, wood chips, and pellets.
- Processed Biomass: Biomass briquettes and pellets.
How is biomass "Carbon Neutral"?
Biomass releases only the amount of CO2 that the plant absorbed during its growth. Unlike fossil fuels which release "ancient" carbon, biomass is part of the current carbon cycle, making it a green energy solution.
Can I use rice husk in a hot water boiler?
Yes. While rice husk is more common in steam boilers, our specialized furnace designs can efficiently burn husk to produce large volumes of hot water for parboiling and other agro-processes.
What is the "Three-Pass" design in your hot water boilers?
The "Three-Pass" design forces hot combustion gases to travel the length of the boiler three times. This maximizes the time the gases spend in contact with the heat exchange surfaces, resulting in high thermal efficiency.
What is the typical efficiency of these boilers?
Our biomass hot water boilers achieve efficiencies of 78% to 82%. When fitted with an Economizer to recover waste heat from flue gases, efficiency can be boosted by an additional 3-5%.
Is the water circulation automatic?
Yes. The system uses a high-efficiency centrifugal pump to circulate water between the boiler and your process equipment (like radiators, kettles, or heat exchangers) in a closed or open loop.
How do you manage the ash produced?
Biomass produces more ash than oil or gas. Our boilers feature large, accessible ash pits for manual or semi-automatic removal, ensuring the furnace remains clean for optimal combustion.
Does it require a water softener?
Yes. To prevent scale formation inside the tubes, we strongly recommend using a water softener. Scale acts as an insulator, drastically reducing efficiency and eventually damaging the boiler.
Which industries benefit from Biomass Hot Water Boilers?
- Food & Dairy: For pasteurization and cleaning.
- Hotels & Hospitals: For central heating and laundry.
- Textiles: For washing and dyeing processes.
- Rice Mills: For parboiling and drying paddy.
Can this boiler replace an electric or oil-fired water heater?
Absolutely. If you have access to low-cost biomass, the "fuel bill" savings are often so high that the boiler pays for itself in less than a year.
Is it suitable for central heating in cold climates?
Yes. It is an excellent off-grid solution for large facilities like warehouses or worker colonies where a constant supply of hot water is required.
Does this boiler require IBR certification?
Hot water boilers operating below 100°C and within certain capacity limits are generally Non-IBR. This simplifies installation as you don't need annual government inspections or a certified boiler operator.
What safety controls are included?
Standard features include:
- High-Temperature Cut-off: To prevent the water from boiling.
- Low Water Level Alarm: To protect the tubes from dry firing.
- Pressure Relief Valves: To prevent over-pressurization.
How often should the boiler be cleaned?
Depending on the fuel, the smoke tubes should be cleaned with a wire brush every 1–2 weeks to remove soot, and the ash pit should be cleared daily.
What is the price of a Biomass Fired Hot Water Boiler?
Prices vary based on capacity (kcal/hr) and automation level. Approximate 2025 rates at indianboilers.com are:
- Small (up to 2 Lac kcal/hr): ₹500,000.
- Medium (5 Lac to 10 Lac kcal/hr): ₹4,00,000 – ₹8,50,000.
- Large (20 Lac+ kcal/hr): ₹12,00,000 and above.
How does the price compare to Oil/Gas boilers?
The initial capital cost of a biomass boiler is slightly higher due to the larger furnace and fuel handling needs. However, the running cost is 60–80% lower than Diesel (HSD) or FO boilers.
What factors impact the final quote?
The total Kcal/hr capacity, the choice of Manual vs. Automated feeding, and the inclusion of Pollution Control equipment (like Cyclone Dust Collectors) affect the final cost.
What is the typical ROI period?
For most Indian factories switching from Diesel or LPG to Biomass (Briquettes or Husk), the payback period is typically 6 to 10 months.
