HOW IT WORKS

The diagram above illustrates how the Recoheat captures lost heat from your solid fuel stove.

1 – Light a good fire in the stove

2 – Heat rises through the flue to be wasted with the exhaust fumes

3 – Air pumps into the sealed Recoheat unit at the bottom of the flue, where it is rapidly heated to about 500 °C

4 – The hot air expands, so shoots out of the unit much faster than it is pumped in

5 – The heat and increased air pressure creates a current of warm air in the room, filling it with warmth

6 – Open the door and warm air flows out into the rest of the house

We make ambitious claims for our eco-friendly multi fuel stove accessory: use half the fuel for twice the heat output.

But it's not actually difficult to understand how the system achieves these remarkable efficiencies. Imagine the area your central heating boiler would warm up if it wasn't connected to a pump that circulated water over the flames and around the house: it wouldn't heat the corner of the room it sat in. Yet, as part of a pumped system, it heats the whole house.

It captures heat from the hottest part of the stove

Our system uses the heat from your stove in the same way - it circulates air through the hottest part of the stove - just inside the chimney - and pumps it into the room.

It's a sealed unit - so no fumes

Because the air circulates in a sealed system inside the flue, it's not affected by the smoke, and it doesn't affect the flow of air in the chimney itself. 

It's transferring direct heat through air

Because the heat is generated by the fire itself, not by radiation from the stove, it's instant - hot air starts pumping within seconds of lighting your fire, and continues pumping for hours after the stove has cooled.

It pumps the air

And because the air is pumped into the room it circulates by its own volition - it's not using convection or radiation to spread warmth into the room.

It'll create a current around your house

In fact the heat that is released does very quickly create a convection current, and you'll observe that current literally spreading around your house - it's observable - and measurable - when cool air comes through the bottom of the open doorway while warm air goes out the top. 

It keeps pumping warm air for hours

Check out the video at the top of the page to see how hot the air is when it's pumped from the system (about 500°C) and how long (six or seven HOURS) the Recoheat pumps warm air after the stove has cooled.

It works with all stoves - new or old

Recoheat really is a revolution in high efficiency wood burning and multifuel stoves, because it offers such high efficiency and works with all stoves, new and old.

How well does Recoheat work - see the video below.

What does the set-up look like?

This how the device is set up, with the air tube connecting to the back of the flue, and air pumped through a nozzle on the front.

It's quite common to have the nozzle at a slight angle so that the hot air doesn't blow into your face when you're opening the door to put fuel in.

The air pump can be concealed in a cupboard or even sited outside (they're waterproof) or in another room: we supply it with three metres of connecting tube, but this length can be increased.
