Description

The Easyfire 2

The Easyfire (AKA Easyfire 2) is an upgraded, sleeker, smaller and more customisable pellet boiler than its entry-level sister, the Easyfire 1. It is suitable for a variety of applications, including:

  • small, medium and large homes
  • farms and agricultural
  • larger buildings, such as schools
  • commercial or industrial premises.

The KWB Easyfire wood pellet heating systems are among Europe’s best-selling wood pellet heating systems. They are among the cleanest wood pellet heating systems in the world.

The unique under-feed combustion system, invented by KWB, ensures a smooth combustion process with ultra-low emissions. KWB's 'cleanEfficiency' technology sets a new benchmark for easy, low emission heating. The Easyfire 2 features the new lambda-controlled combustion system, with a highly efficient heat exchange using turbulators and an integrated return flow temperature boost.

It is available in a large range of sizes, from 2.4 kW all the way up to 35 kW. 

The boiler has a footprint of just 0.75m², enabling it to fit easily into most boiler rooms or utility spaces.

There are many different fully-automated methods of refuelling available with the Easyfire 2, so you can choose one to suit your own situation and preferences. The customisable solutions include:

  • 'Big Bag' pellet storage, with either a suction conveyor or an elbow screw to take the fuel into the boiler
  • The 'Pellet Stirrer Plus', which maximises storage space in the pellet room (this can also be fitted with either a suction conveyor or an elbow screw)
  • a Conveyor Screw (fitted with either suction or elbow screw)
  • The 'Pellet Box' option, with suction conveyor
  • a simple small-bag storage container
  • KWB Sample Probes, with suction conveyor

....you can see examples of all of these, further down the page: see ''fuel storage examples' below

The Easyfire 2 comes with the highly-programmable and easy-to-use 'Comfort 4' control panel. It has a touch-screen display, a tried-and-tested control dial, and can even be controlled remotely. You can log in to your boiler online, allowing you to remotely control and monitor your heating system with greater flexibility than ever before.

Its power consumption is very low – it has an energy-efficient drive motor, which uses very little power.

The Easyfire 2's automatic heat exchanger cleaning eliminates the need for cleaning between services.

Emptying the convenient movable ash container is easy and comfortable – and you may be surprised at how little ash is produced!

Easyfire 2's technology in detail

Simple Drive Concept

Energy-saving drive motors for pellet and ash transport ensure low power consumption. A large rotary feeder with metering screw permits a safe and efficient pellet feed.

 

 

 

 

 

Simple Planning

The fully integrated and volume-controlled return flow boost enables connection of the wood pellet heating system to any existing heat distribution system. Unlike conventional wood pellet heating systems, there is no need for an external return flow boost. This saves you additional installation costs.

 

 

 

 

Straightforward Assembly

The modular system with lightweight and compact components allows the new KWB Easyfire wood pellet heating system to be easily moved into a boiler room. No matter whether you have to negotiate narrow passages or steep staircases – the compact dimensions of the heating system make installation straightforward. The fully installed heating system has a footprint of just 0.75 m².

 

 

 

 

Clean Due to 96% Efficiency

The special springs installed in the heat exchanger ensure optimum heat exchange and low exhaust gas temperatures.

 

 

 

 

 

 

Emissions at the measurability limit

The special geometry of the dust separator, with its cyclone effect, produces eddies in the combustion gases. The heavy dust particles then sink and do not enter the chimney.

 

 

 

 

 

Controlled Combustion

Combustion is continuously monitored and optimally controlled by the broadband lambda probe, which has been specially developed for biomass heating systems. A new ceramic ignition element with flame detection ignites the combustion intermittently within approx. three minutes. You benefit from low energy consumption and high operational reliability.

 

 

 

 

under-feed combustion system

In the new KWB Easyfire wood pellet heating system, the pellets are pushed gently onto the burner plate from below. The fuel bed therefore remains completely stable and no additional dust eddies are generated. The pellets burn out completely in four clearly delimited combustion zones.

 

 

 

 

Fuel storage examples

 

KWB Pellet Big Bag and elbow screw

KWB Pellet Big Bag and elbow screw

  • The ideal storage system when there is no separate pellet storage room or when the pellets are weather-proofed and stored outdoors.
  • Standard sizes of 2.2 to 10.5 tonnes of pellet capacity are available.
  • Produced from anti-static fabric and fully dust-proof.
  • Maintaining a minimum distance from the wood pellet heating system, the KWB Pellet Big Bag can be set up in the boiler room itself (depending on local fire safety regulations), in a separate storage room, or be set up outdoors, if weather-proofed.

  • The KWB Pellet Big Bag can also be supplied together with a suction conveyor. This enables suction lengths of 25 m and height differences of up to 5 m between the boiler room and pellet storage room to be easily overcome.
  • For sizes and set-up options, see KWB Pellet Big Bag with elbow screw.
