DEKi MAXI, Wood pellet biomass central heating boilers.

Our range of DEKi boilers are extremely efficient biomass wood pellet boilers equipped with high level of automation which reduces users input needed for machine to operate. 

Like all of our boilers, DEKi maxi represent simple honest and solid engineering with minimal reliance on electronics, unnecessary sensors and easy to use automatic programmer.

How it works? This type of a biomass boiler is for use with large or energy thirsty applications, where high level of automation is required. The boiler comes equipped with auto ignition self cleaning burner, which means it can be switched on remotely even after sitting idle for long periods. Power outputs are from 10 to 80kW and with high internal water volumes these can be used with or without buffer tanks. We also offer customisation of this model which covers, hopper orientation & hopper volume, so a say 10kW & 65 litre hopper can be supplied with a hopper from 80kW boiler which holds 900 litres of pellets equivalent of around 700kG, this gives extra long burn times before boiler requires to be refilled. These boilers can also be connected to a much larger wood pellet store, something like a silo or large storage space.

As a rule of thumb the ashes from this model will require emptying once every month to once every 3 months of continued use, usually a cubic meter of pellets produces around cubic foot of ash, this is a rough but real life guide and varies with pellet quality.
