Description
The Thermalux Dynamic 3500 is a wood-fired hydronic boiler designed to provide strong hydronic heating performance for medium to large homes. The waterways and smoke paths have been designed to maximise heat transfer by drawing usable heat from multiple sides of the firebox.

The Dynamic 3500 delivers up to 35kW of hydronic output and is suitable for use with radiators, convectors or underfloor heating systems. It can heat homes up to approximately 300mΒ², depending on home design, insulation, climate and system configuration. In suitable installations, it can also provide up to approximately 5kW of radiant heat into the room, giving the atmosphere and warmth of a traditional wood fire.

For living area installations, the Dynamic 3500 is available with a glass firebox door for fire viewing and visual ambience. For more utility-focused applications, it can also be configured with a solid firebox door and insulated top, making it suitable for garages, plant rooms or service areas. Domestic hot water can also be integrated via a suitable heat exchange hot water cylinder, allowing the system to support both space heating and hot water.

Customisation: Left or right side heat shields, brass spring handles, flue kits, and decorative flue mesh options are available at additional cost.

Frequently Asked Questions

What is the best wood to use?

For best performance and long-term durability, use only dry, seasoned Australian hardwood. AHHA recommend using firewood with less than 20% moisture content.

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.
