Hydronic wood fired boilers are back in demand, and finding the right one for your home or office that suits your needs can be a bit tricky. Hydronic boilers have low maintenance costs and are slightly cheaper. If you want to buy a wood hydronic boiler, Kroll Heaters offer a wide range of sizes and types. The Ventum or VG40 40kW boiler is over 91% efficient. The VG30 30kW boiler is also available.The Caria Pellet boilers are certified over 93% efficient. Caria is available in 23kW and 40kW up to 100kW. The Ventum boilers require thermal storage tanks to be the heat bank or hot water storage for your home. It is best to have 50 litres of storage per kW of load. EG: a 20kW load needs 1000l of thermal storage, a 40kW load needs 2000l of thermal storage.
Thermal Storage
Thermal storage is an important component of modern wood boiler systems. By absorbing extra heat generated during the burn cycle, heat storage allows wood boilers to operate with less tending, lower emissions and higher efficiency. Heavy tank insulation holds stored heat, allowing for 24 hours or more between burn cycles. Wood boilers used properly with heat storage will form no harmful firebox condensate and will outlast boilers used without thermal storage. Heat storage is a condition of some wood boiler warranties and EPA approvals.
Using properly sized heat storage with wood log and wood pellet boilers can reduce on/off cycling by half or more. Reducing cycling dramatically decreases emissions and the need for boiler service, while improving heating response time. This means less ash creation and a higher degree of building occupant comfort.
Continuous Burning or Batch Burning
Because wood burns best when burned continuously, but most buildings cannot take the full output of the boiler, insulated water tanks are used as thermal storage for excess heat. The heat stored in the water can be used for many hours after the fire has burned out. Most of our customers report visiting their boilers no more than once every 12 hours in the coldest weather. When the weather gets warmer, visits to the boiler become less common. If just a little heat is needed, the heat in the storage tanks often will last 2 days or more. A special charging valve called he LK Armature 810 is used to fill the tank from top to bottom with 80C water.
It’s important to determine how much floor space you intend to cover. Most wood boilers work well for a standard-sized home with three bedrooms. If you have different requirements, you might need to opt for a custom-made boiler. Kroll supplies state-of-the-art Ventum, or VG Series boilers to meet all types of requirements, whether industrial or personal. Ask about the Caria for wood pellet heating.
Safety:
Although wood boilers generally provide more safety compared to other boilers, they can still pose serious health hazards, especially for homes with kids and pets. Pay close attention to the safety provisions of a wood boiler. Consult the manufacturer to learn best practices for using them. The Ventum is RCM electrical safety compliant.
Efficiency:
Wood hydronic boilers in Australia are not particularly known for their fuel efficiency, however, right now, the Ventum or VG boilers are over 90% efficient and certified to European Standard EN303-5, Class 5. Wood can be expensive and hard to procure and store, so the efficiency of wood-fueled boilers is crucial to avoid becoming a part-time lumberjack! Kroll offers a range of accessories that you can attach to our hydronic boilers to customize them fully.
Accessories:
Although hydronic boilers don’t require additional accessories like steam boilers (which need a pump to function), you might still want to consider any additional accessories you may need based on your requirements. It’s important that the boiler you buy can function with the accessory you plan to use. Buffer tanks are a great option to increase efficiency. Ecomax provides remote control.
Legal compliance:
Some countries have enacted comprehensive laws to regulate all types of boilers, including steam and hydronic boilers. If you are getting a custom-made boiler for your place, be sure to check the relevant laws governing boilers, if any.

The boilers are very expensive equipment to repair and even more if they have to be replaced, so it is convenient to make an annual maintenance plan to keep your boiler in optimal conditions. Regular maintenance and repair will not only help you to save money in the long term, but it could also save your life since a defective boiler can be a potential danger to your home and family.
It is also essential to remember that a revised boiler and its daily maintenance is more efficient, so it will be reflected in your energy bills. Luckily, boiler maintenance is not particularly difficult, especially if you follow some of the following recommendations:
Annual Boiler Maintenance
You should check your wood hydronicboiler once a year by a specialized and accredited technician in boiler maintenance, even if it seems to be in good working order. The technician should check, in general, all parts and clean the components. At the end of summer, it is a good time to organize the service, so you can rest assured that your boiler will be in optimal conditions for the winter months.
Scheduled operation
Boilers can present problems if they are not used regularly. Therefore, for good maintenance of boilers, experts recommend that the heating be switched on for ten or 15 minutes from time to time during the summer months, only to keep the boiler running and that no problems arise due to the non-operation of the boiler.
Control low pressure
Wood boiler Australia lose pressure over time, which can affect their operation to occur inefficiently. Check the boiler pressure gauge if you can and, if necessary, put more pressure on the circuit. If you are not sure of what you are doing or the optimum pressure the circuit needs, contact a specialized technician or consult the manual.
Purge the radiators
If your radiators are cooler in the lower part than in the upper part or hear strange noises when the heating is on, that means there is air in the system. Therefore, it is necessary to release the air by purging the radiators. If this is not done, the system will not be working efficiently, causing the pressure indicators to vary and the different zones not be adequately air-conditioned.

Disconnect the heater before purging the radiators, then turn the purge key to the left and you should hear a hissing sound when the air escapes. When the water starts to drip, close the valve and the work will be finished, although you may have to raise the pressure of wood hydronic.
Warning signs
The leaks, cracks, noises or black soot marks, means you have a problem. So check your boiler regularly and be alert for any warning signs. The sooner it is detected and repaired better before a more serious fault is caused. It is also convenient to make sure that any external vents such as ducts are free of obstructions and dirt.
