WBi 40 kW Solid Fuel Biomass Central Heating Boiler

WBI boilers bridge gap between multi fuel burning capability of solid fuel burners and an automatic technology of wood pellet type machines.

Fan assisted air injected multi fuel wood, coal and light waste boiler.

These boilers range with output from 9kW to 50kW

Based loosely on the well established and provenWB boilerchassis, theWBI rangeofmulti fuelboilersmakes most of multi fuel capability by introducing computer controlled fan assistanceto aid burn process.

Combine this with class leadingfirebox sizes a refill times of around 10-14 hrs are achievable. For fire box sizes please see the spec chart as sizes vary withboileroutputs.

Theselog boilerscan be used toburn wood, logs, timber, coal, peat, garden waste, light domestic wasteand othercombustible solid fuels.

Theheatgenerated byburningfuel is used toheat up water circulatingaround thefirebox,grate and exhaust channelsheat exchanger, the water is thencirculatedaround thecentral heatingandhot water cylinder or buffer tank.

TheWBI series multi fuel boilershaveincineratorlike characteristics, produce vast amounts ofheatfromburning solid fuels.

Taking a look at the machine itself:

On top of thismulti fuelburneris the controller. Equipped with latestintelligent algorithms, they require very little input once programmed, with the initial programming taking no more than 1 minute they can differentiate between various power demands to keep hot water supply temperature curve, flat.

Looking at the front, top opening has maintenance access for cleaning out theheat exchanger channels,cleaning equipmentdevicesareincluded. This task takes 3-4 minutes every 3-6 weeks.

Middle door is used forloading of fuel.

Bottom door, gives access to lighting of fuel,cleaning and ash emptying. Ash emptying is typically every 1-3 weeks depending on the fuel.

The fumes exit through the opening at the rear with a further cleaning access panel located just below that.

Multiple pump control capability.

The WBIburning direction of fuel is from bottom up, but always light from top.

Our range ofmulti fuel boilersare not to be confused with inferior units made out of sheet metal. Ourboilersaresolid, well made, intelligently engineeredand constructed out of 5-6 mm purpose made steel, then laser cut with their mass being in the region of between 300-550 kg.

Engineered to last!

Ideal for allcentral heating applicationsventedorpressurisedsealed systems and burning of mostsolid fuels.

Relevant European approval.
