Despite their very good performance, inserts and fireplaces with closed hearths do not distribute the pleasant heat of the fire evenly. A disadvantage that can be eliminated by equipping the chimney with a hot air distribution system. The key is homogeneous heat distribution in all rooms of the house and energy savings.

[EN VIDÉO] First in France: district heating uses stored heat In Brest, the university is heated by a water reserve… but only at the end of the weekend. This thermal storage installation, unique in France, makes it possible to smooth the supply of energy on a district scale.
Insert or closed hearth, use a chimney as the main source of heating requires some adaptation. Indeed, if this equipment has a very good yield (between 70 and 85% door closed), they cannot heat an entire house on their own. In question, a diffusion of the heat limited.
To take advantage of this heat in bedrooms or an office, it is necessary to equip the fireplace with a distribution system.air hot. Compatible with all fireplaces, the Rubis model from DMO can be installed in a single-storey or two-storey house. This device consists of:
- a distribution group;
- a filter box;
- from two to eight blowing outlets;
- thermally and sound-insulated ducts (Ø 150 and 125 mm);
- a wireless room thermostat.
Displaying a debit 550 m of air3/ h, the brew group is powerful enough to blow hot air at a distance of between ten and twenty meters. A fairly wide range which depends on the quality of the site preparation and the laying of the ducts.
Spread healthy heat
To recover the heat, a semi-rigid drawing duct is installed inside the chimney hood. Before being diffused in the various rooms, by blowing outlets, the hot air is filtered beforehand in order to ensure an optimal quality of air.
Better heat and save energy
Motorized, the distribution group comes into operation a few minutes after the start of the outbreak. Associated with a thermostat wireless room, it delivers hot air according to the desired temperature. Programmable, this room thermostat is not a multizone model. It is therefore essential to choose the right location (far from a source of heat, drafts, etc.).
Faced with the incessant increase in the cost of gas or electricity, installing this hot air distribution system makes sense. An investment of around 650 € incl. Tax which saves on the invoice annual heating, while promoting renewable energy and cheaper.
What you must remember
- The installation of a heat recuperator is carried out as well in the new as in renovation.
- The installation of this heat recuperator is accessible to good do-it-yourselfers but requires meticulousness.
- For 100 kWh, the cost of energy is € 6.23 for wood, € 7.51 for gas and € 17.98 for electricity (Pégase 2020 data).
