Description
The Thermalux Linea is a compact wood-fired hydronic boiler designed to provide hydronic heating for homes where consistent, even warmth is desired. With up to 20kW of hydronic output, it can support heating for homes up to approximately 200mΒ², with performance depending on home design, insulation, climate and system configuration.

Rather than heating with radiant heat, the Linea heats water for circulation through radiators, convectors or underfloor heating coils. Freestanding models also provide up to approximately 5kW of radiant heat into the room, while the large glass firebox door offers the visual appeal and atmosphere of a traditional wood heater.

The Linea features an ash-bed style fire chamber with a modified ashpan system for convenient ash removal, even while the unit is operating. It also includes an integrated damper helping to regulate combustion temperatures and support efficient hydronic heating performance. The top surface can also be used as a practical warming plate for light use, such as keeping a kettle warm.

Supplied accessories: 1x Ash scraper, 1x Knob turner, 1x Pair of fire gloves.
Customisation: Available with Queen Anne style legs, pedestal base or as an inbuilt unit. Brass spring handles, flue kits, and decorative flue mesh options are available at additional cost.

Frequently Asked Questions

Will the Linea provide enough radiant heat to warm my room?

Whilst the Linea may provide some radiant heat, it is not intended to heat a room directly. It is a purpose-built wood boiler for hydronic heating that heats water, which is then circulated through radiators or underfloor heating to warm the home.

Why is there water coming from the bottom of my boiler?

This is usually condensation, not a leak. Condensation can occur when the firebox does not maintain a consistent operating temperature and is allowed to cool too often, or when the wood being burned is green or not properly seasoned. For best performance, always use dry firewood and check the moisture content before burning.
