The FHT Stove
The stove that connects directly to your central heating system
to control comfort, save money and reduce your carbon emissions

FHT Stove Schematic

The FHT Stove is a unique wood burning stove design which incorporates all the features of modern, clean-burning, efficient convector stoves and adds an extra dimension! The patented technology safely diverts hot air from the sides of the stove to any central heating circuit. Heat transfer can be turned 'on' or 'off' so that you can choose whether to have all the stove heat going to the room or to divert approximately half the heat into the central heating system. Turn 'on' or 'off' as often as required.

The FHT Stove:

The wood burning stove that connects directly to central heating circuits
Unique control of stove heat output for room comfort
At the flick of a switch half the stove heat transferred to the central heating circuit
User chooses when/if they want heat to be transferred
No 'back boiler', no 'heat sink' radiators, no expensive 'link up' equipment
Disperses excess heat to other parts of the home
Works with pressurised central heating circuits, including 'Combi' boilers
Reduces fuel consumption in the central heating boiler, saves money and reduces carbon footprint

How the FHT Stove Works Up Arrow

A low-power, low-noise fan in the base of the stove reverses natural convection over the outer surfaces of the firebox. When the fan is ‘on’ warm air that would normally come out of the top of the stove is directed to a heat exchanger under the firebox. The heat exchanger acts like a car radiator in reverse, taking heat from the hot air into the central heating circuit. When the fan is ‘off’ heat comes out of the top of the stove as normal. Around half of the stove heat can be diverted to the central heating system – instantaneously!

No combustion gasses pass through the heat exchanger or enter the room.

Too hot? – divert half the heat to other rooms or hot water - fan 'on'
Not warm enough? – choose to have all the stove heat in the room - fan 'off'
Turn ‘on’ and ‘off’ heat transfer as often as you like
Reduces the convective heat (hot air) when 'on' but maintains the comfortable radiant heat
Instantaneous transfer of heat - the ultimate in stove heat control
A straightforward principle of operation, matched by strong Engineering implementation for safe, quiet and reliable operation
Patent granted in many regions of Europe, Canada and New Zealand
