Product Description

Effective 1st July, the EU rolled out new eco-design legislation impacting space heaters sold across Europe, including Ireland.

The Key changes are: –

• An increase in the seasonal space heating energy efficiency value from not less than 74.0% to 80.0%.
• Reduction in NOx emissions so that they may not exceed 180 mg/kWh from 200 mg/kWh.

To meet these new standards, the upgraded BT’ heaters now deliver <180 mg/kWh NOx emissions and officially replace Vision Radiant systems sold in the EU only.

What’s New?

The 2025 ErP-ready BTHE and BTLHE models simplify installation thanks to a cast aluminium monobloc burner that integrates the combustion fan directly into the burner housing. This smart engineering makes them the go-to solution for radiant heating across Europe.

With net heat outputs ranging from 20kW to 50kW (gross), the BTHE and BTLHE range maximises radiation efficiency using advanced reflector technology.

These low-NOx radiant gas heaters feature a slimline emitter and a refined, modern design. Updates include redesigned end caps, robust support brackets, and a sleek new canopy on the BTLHE variant. The compact build incorporates deeper reflectors that direct heat downward, minimising loss to ceilings and surrounding areas.

• BTHE – ‘U’ Tube
