About this product

Will it suit your space?

As a rule of thumb, an average room needs roughly 1kW for every 14 cubic metres, so its 7kW suits about 98 cubic metres (around 41 square metres with a 2.4m ceiling). Older, draughty or high-ceilinged rooms need more, and a heat-loss check by your installer gives the right answer.

The Harmony GD is 1089mm high, 598mm wide and 437mm deep and weighs 123kg. It needs 420mm clearance to combustibles at the sides and 180mm at the rear.

Installation and safety

It must be installed by a HETAS-registered installer or signed off by Building Control, and a carbon monoxide alarm is required in the room. Follow the clearances and hearth details in the Opus installation manual.

Questions

Can it burn coal or smokeless fuel?

No. Opus and Firepower list the Harmony as a wood burning stove, and the manual rates it on wood only.

Can I use it in a smoke control area?

No. The Harmony is listed as not DEFRA exempt, and there is no SE version on the current Firepower price list.

What size logs does it take?

Logs up to 330mm long. The Harmony GD burns wood only.

Return and refund policy

Warranty

The manufacturer's warranty terms apply, which can include registering the product, professional installation and annual servicing. Your rights under the Consumer Rights Act are not affected.

Installation and safety

In England and Wales, installing a solid fuel appliance is notifiable building work: use a HETAS registered installer, or apply to Building Control before the work starts. Scotland and Northern Ireland have their own building standards.
Building Regulations require a carbon monoxide alarm in the room when a solid fuel appliance is installed.
In a smoke control area you can only burn wood in an exempt appliance; otherwise you must use an authorised smokeless fuel. Check before you buy.
