Product Description

Combining elegant design with versatile functionality, the HS Tarm DBK gives you the option of having both the low cost operation of a 30kW log boiler and the automated practicalities of a 22kW pellet boiler.
With automatic change-over between log firing and pellet firing, this boiler allows rare flexibility in operating a biomass system without compromising on quality.

The DBK meets the stringent efficiency and emissions requirements of the EN303-5 class 5 standard for biomass boilers and is MCS accredited and approved for the government RHI scheme.


Top features:

♦   Dual fuel boiler (22kW pellet / 30kW log)

With separate burners to maximise the efficiency of logs and pellet fuels, the DBK allows you real flexibility in matching your biomass fuel to both your budget and routine.

The DBK is designed for connection to an accumulator tank of between 1200 and 2000ltrs.

Automatic changeover from logs to pellets

The pellet boiler remains in standby when burning logs, and will ignite automatically if the upper tank temperature falls below a set point.

Awarded EN303-5 Class 5 standard

 The HS Tarm DBK meets the requirements for the highest EU biomass boiler standard for emissions and efficiency.

♦   Easily adjustable, intuitive controls

The control panel is easy and intuitive to navigate, allowing you to monitor and control your boiler’s operation — without needing to call out an engineer.

♦   Large log chamber

The log boiler on the DBK comes with a 110ltr firebox, which can take a genuine 1/2m log.

♦   Mechanical cleaning of the heat exchange tubes

The simple operation of the cleaning handles ensures the heat exchange surfaces are kept clean and continue to work at maximum efficiency.

♦   Flexible pellet storage

The 1.6m pellet auger is suitable for use with a small hopper (as in the HS Tarm Deluxe hopper) or the optional 2.5m pellet auger is suitable for use with a large external pellet silo.
The matching 400 litre HS Tarm Deluxe pellet hopper (as shown above) is available with the DBK at a discount or it is available separately. Please see the related products below.
