FAMAR GEYSIR WOOD 5S multi-fuel automatic boiler

The Geysir Wood 5S boiler represents a real revolution in the wood-pellet boiler market.

Capable of automatically switching from one fuel to another while keeping the power transferred constant. The user can choose to operate only wood, only pellets or in combined mode. Equipped with a single and large combustion chamber with bottom loading, it is able to burn any type of wood, pellets and multi-fuel at the highest levels of efficiency. Characterized by very high performance and very low emission values. Complies with the most advanced European industry regulations.

Hydraulic Information

1 – Warning: Even if the smoke outlet duct has a diameter of 100 mm, use a flue with an internal diameter greater than or equal to 150 mm. To make a suitable connection to the flue duct to reduce any noise during the smoke escape phase, use 100-120 and 120-150 fittings.

2 – Vent valve 3 – DHW flow switch 4 – ISPESL safety valve outlet 2.5 bar Ø 26 mm 5 – Safety valve outlet 2.5 bar Ø 21 mm 6 – Expansion valve 10 L 7 – System delivery Ø 1″ M 8 – DHW outlet Ø 1/2″ M

9 – Thermal drain valve outlet Ø 3/4″ M 10 – Domestic water/mains water inlet Ø 1/2″ M 11 – High efficiency primary system circulator 12 – System return Ø 1″ M 13 – High efficiency circulator for anti-condensation function and rapid DHW 14 – Boiler drain tap

ALL-ITALIAN TECHNOLOGY AND FUNCTIONALITY

The Geysir Wood 5S is able to burn wood, pellets, multi-fuel or in combined mode without problems.

Once the boiler has been prepared for ignition (by inserting wood into the combustion chamber and the pellets/multi-fuel into the tank), the glow plug with its blower causes the pellet/multi-fuel to ignite, which in turn triggers the ignition of the wood. When the wood reaches a suitable combustion, the electronic control blocks the supply of pellets/multi-fuel and the boiler will run exclusively on wood. When the boiler is exhausted, it automatically restarts with pellets/multi-fuel. If the system no longer requires energy, Geysir is placed on standby , minimizing wood burning, automatically closing the combustion air inlet. If the boiler is working exclusively with pellets/multi-fuels, it is possible to load the wood normally from the hatch. When the door is opened, an actuator opens the smoke by-pass damper, making them pass directly through the flue, increasing the flow rate of the extractor. This prevents the abnormal exit of fumes into the technical room. The same principle applies in the case of pellet/multifuel operation.

GEYSIR “BURNS” PLANT BIOMASS OF ANY TYPE WITH INNOVATIVE BOTTOM LOADING SYSTEM

The large tank is connected by a double jump screw plus rotary valve to the circular cast iron burner. Advanced bottom-loading technology allows you to take advantage of multiple benefits:

• absence of burner cleaning;

• clean white flame and always with the right amount of oxygen;

• reduction of fuel used. When the boiler is placed on standby, it does not use any other fuel for new restarting, but uses the ember effect to start again;

• possibility of using pellets and biomass of any type and quality. Theburner equipped with a removable ring, once removed, is able to burn even more difficult fuels as the surface is larger with additional holes for combustion.

SELF-CLEANING

The Geysir Wood heat exchanger is self-cleaning due to the thermolytic surfaces it contains, so only ash and fine dust are deposited which must be removed only once a year for cleaning and extraordinary maintenance.

THE GEYSIR WOOD EXCHANGER

Designed and sized with fluid dynamics software, the heat exchanger (Famar patent) consists of fins with 24 smoke pass passes. Fully automated: An actuator opens or closes the bypass dampers by changing the passage of flue gas into the flue or dry chamber heat exchanger.

Specially studied and designed with narrow and long passages, with nailed fins in the center in order to ensure the overheating of the internal walls to the passage of fumes. The incandescence of the internal contact surfaces burns the unburnt materials carried by the fumes, transforming them into ash, which remains on the internal surfaces due to the cyclone effect of abatement, as well as recovering additional energy (greater efficiency) which is transferred to the water.
