This range is one of the most highly efficient available. At 92% heat efficiency it burns off all the gases and has a minimal ash output. These boilers can have as short a payback period as 3 years over LPG, Gas or Oil.They can heat 3 bed houses up to country mansions.
They can take logs from 500mm to 1000mm long and 6" to 10" diameter depending on the size of boiler.
They must be installed with an appropriately sized accumulator tank to obtain maximum working efficiency.
Using the latest downdraft technology, this gasification boiler burns all the gasses produced during the normal burning process, therefore allowing minimal CO2 to be released into the atmosphere. The secondary burning chamber burns gasses at up to 1200 degrees centigrade. Regulated by a digital display panel which controls the ventilator fan, this enables the boiler to be 92% efficient. The boiler has a large log chamber which holds enough wood for up to 12 hours burning.
The boilers are available in the following sizes 18, 25, 40, 60, and 80kW.
The boilers are ideally suited for installations on an open vented system. The expansion tank should be 10% capacity of the whole system. If in doubt allow 20-25% of the volume of your accumulator tank.
The boilers can also be installed in a closed (pressurised) system but attention must be drawn to use of a pressure vessel[s] dependant on each application. The pressure vessel on the CH circuit will usually be sited before the CH return to the accumulator tank or between the laddomat thermo regulator and the boiler. It is generally recommended to allow 10% capacity of the whole system for your pressure vessel for wood log gasification boilers. If in doubt allow 20-25% of the volume of your accumulator tank and check the pressure set in the vessel.
If mains pressure hot water is required for the hot water then we would suggest an Akvaterm tank with a DHW coil (22mm finned copper coil tested to 10 Bar). It will also be necessary to introduce a safety group on the boiler under a pressurised system (pressure gauge, pressure relief valve and automatic air vent).
The boilers are exceptionally economical. A 40kW boiler typically uses a similar amount of wood as a conventional log stove but at 92% efficiency it provides infinitely more heat via your accumulator tank.
To maintain ample hot water during the summer months, the boiler needs only to be lit every 3 to 4 days. Depending on your source of wood this boiler offers fantastic savings over conventional systems.
We believe the Angus Orligno 200 wood log gasification boilers to be exceptional value for money within the top range.
