This is a boiler stove

Most of its heat goes into your radiators and hot water, and about 2.6kW warms the room it stands in. It connects to your central heating, so you need a heating engineer as well as a stove installer.

What you'll need

Everything to get this stove lit

A stove on its own isn't enough. Here's what comes in the box, what else you'll need, and what your installer brings.

In the box

  • The stove and the manufacturer's installation and user manual

You'll also need

  • A carbon monoxide alarm. Required by law in the room with the stove.
  • Stove pipe to connect it to the flue. Your installer will tell you the length.
  • A hearth for it to stand on, if you don't already have one.
  • A load unit for the heating circuit, fitted by your heating engineer.
  • A chimney liner or twin-wall flue. Your installer supplies this.

Your installer brings

A stainless steel liner sized to the stove and a register plate to seal the chimney, usually after the chimney has been swept and checked.

Fitting, testing and a certificate showing it meets Building Regulations. Keep it for your home insurer and for when you sell.

A boiler stove also needs a heating engineer to connect it to your radiators and hot water. The manual lists these parts too:

  • A heat leak radiator, so heat can escape if the pump stops
  • A thermal safety valve on the cold mains, connected to the stove's safety coil
  • A pressure relief valve, if your heating system is sealed
  • Antifreeze in the heating water

Ask for one quote that covers the survey, flue, fitting and certificate. Using someone who isn't HETAS registered? Your local building control must approve the work before you use the stove.

About this product

Will it suit your space?

Only about 2.6kW to 2.7kW reaches the room directly, depending on body style. As a rule of thumb, an average room needs roughly 1kW for every 14 cubic metres, so that suits about 36 to 38 cubic metres (around 15 to 16 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.

Both body styles are 520mm wide and 440mm deep, weigh 130kg and take logs up to 330mm long; check the sizes table below for the height. Woodfire sets a maximum recommended flue diameter of 160mm, and the stove is not suitable for a shared chimney.

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.

The boiler circuit should be designed and connected by a competent heating engineer. The stove is not suitable for a shared chimney.

Questions

How much heat does it give to the room?

From an 8kW nominal output, the CX8 gives about 2.6kW to the room and 5.4kW to water, and the CXC8 about 2.7kW to the room and 5.3kW to water.

Does it need a flue and a load unit?

Yes. It needs a 150mm flue suitable for solid fuel, and Woodfire requires a load unit or load valve with the pump controlled by a flue thermostat or controller. Without a load unit the warranty drops from three years to one.

Can it go on a pressurised heating system?

Yes. Firepower lists it as suitable for vented and pressurised systems.
