HS Tarm Pellet Boilers

Designed and manufactured in Denmark, HS Tarm pellet boilers provide an elegant and versatile biomass solution for your domestic heating requirements. Fully accredited under MCS, HS Tarm pellet boilers meet the stringent criteria for the RHI scheme. 

As registered MCS installers, we can install any of these boilers ourselves in the Scottish Borders and nearby.  If you live further away, we can pass your details on to one of our registered installers.

If you would be interested in becoming a registered installer, please contact us for more information.



A compact and efficient wood pellet boiler combining Danish design with ease of use, the TPK modulates between 6-22kW. Its features include automatic ignition, easily adjustable controls and mechanical cleaning of the heat exchange tubes. It is well insulated, and comes with a separate burner and 1.6m auger as standard. An optional 2.5m pellet auger is also available. This allows the boiler to be directly connected to either a small adjacent pellet silo or a larger external fuel store.

A matching 400ltr powder coated pellet hopper is also available (shown in image).


If fuel cost is a consideration, we can also offer a versatile combined pellet and log boiler, the DBK:



Combining elegant design with versatile functionality, the 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.



HS Tarm are currently expanding their pellet boiler range, and we hope to offer larger pellet boilers later this year.
