	Generally heat from combustion is only circulated once the stove body has itself been heated. Once the stove is hot, the radiant heat creates a convection flow that circulates the heat into the room.

	The Recoheat captures and circulates the combustion heat as soon as it starts to pass up the flue, so the heat is being exploited immediately. It then continues to circulate heat through the entire heating and cooling cycle, which is likely to be four to eight hours longer than the stove is being fuelled for: stove users will know that the embers in their burner will still be hot the morning after a fire. Even if this only succeeds in heating the air from the Recoheat to 30 degrees, that air is still circulating and can make an enormous difference to the temperature of the property. The reason for this is that heating a house back up from an unheated temperature requires far greater calorific investment the lower it’s required from. Nor is it a steady curve because brick has no insulating qualities once its temperature drops below 15 degrees, so if it can be maintained above that temperature, far more of the heat in the home can be retained.

	The simulations confirmed that a Recoheat brings a room up to a temperature in 10 minutes that a stove alone produces in an hour. The average temperature in the model room after one hour is also 4 degrees warmer, but that figure doesn’t describe the change in comfort levels provided because of the way that average is achieved: the stove alone produces a very hot area around the stove and flue, with that heat circulating along the ceiling as time passes, but the majority of the room being significantly cooler. In contrast, the Recoheat creates a temperature that is even throughout the volume of the room, including floor to ceiling.

	Crucially, the model demonstrates how that’s achieved. It shows the element heating, expanding and accelerating the air pumped through the heat exchange so that a jet of hot air is propelled from the outlet. This air entrains the hot air rising from the stove and directs it into the room. It also entrains the cold air in front of the stove, and as this mixes with the jet, it destabilises it – so instead of rushing out in a steady flow, the jet starts to oscillate until it’s sweeping around in a rough circular motion in front of the stove. That motion stirs and mixes the air in the room floor to ceiling as observed like a giant fan blade composed of warm air.		Crucially, the model demonstrates how that’s achieved.

	Something else to note, though, is how efficiently the Recoheat device exploits the heat produced by the fuel combustion, so how much less fuel is required to produce how much more heat. Part of this is a result of the heat capture during the burn, but as much is because of the time period that the heat from combustion is circulated for.

Many customers report heating their whole homes from a single stove with a Recoheat fitted, and while the initial year of sales saw customers with smaller two-bedroom cottages reporting this, the largest homes now reporting this are 4 bedroom properties with three storeys.

	People in homes with very cold walls, including old stone houses, a couple of yurts, timber cabins and boats, report that the warm air flowing from the units form a pocket of air against the walls, effectively insulating them and allowing the rooms to be heated to the edges.

A secondary effect of this characteristic is that condensation is removed. This is instantly observable on a boat where condensation is a constant in cold weather: the Recoheat removes it with the flow of warm air it sets up in the space. The first customer to report this did so from their 70 foot by 14 foot widebeam canal boat, so the area it is effective in is large.

	Anecdotally, the units are incredibly effective with particular characteristics that distinguish them from other forms of heating. In fact, since 2022, the company has employed engineering consultants Cambridge Engineering Analysis & Design in order to understand the effects reported.

	Many older properties rely on a wood burner for their primary heat source, because the building materials and lack of insulation mean older homes are expensive to heat with oil or electricity. Solid fuel stoves are a great way to heat a room, and offer efficiency and comfort levels far beyond those offered by open fires.
