T-LOFT Plus - Speicherofen von der Tonwerk Lausen AG

Die Tonwerk Lausen AG

Die Tonwerk Lausen AG beschäftigte sich seit ihren Anfängen mit der Produktion feuerfester Steine sowie der Kunst, die Energie der Flammen so effizient wie möglich zu nutzen. Zusammen mit einem weltweit bekannten Designerteam und einem Spezialisten für Feuerungstechnik entstanden unsere einzigartigen Speicheröfen, die die Wärme im Kern eines von Tonwerk speziell entwickelten Steins speichern und als angenehme Strahlungswärme abgeben. Ein Feuerungssystem für eine umweltfreundliche und effiziente Holzverbrennung. Kompetenz in Technik und Design, verbunden mit der Handfertigung in unserer Manufaktur, unterstreichen die Individualität unserer Speicheröfen.



If your house was built or renovated to low-energy specifications, the T-LOFT PLUS heat storage stove is all you need to keep it warm and cosy (subject to your technical installation and requirements). In other buildings, the T-LOFT PLUS is an excellent addition to the existing central heating - particularly during the shoulder season.

T-LOFT PLUS - the clever heating alternative

The Tonwerk storage stove T-LOFT PLUS is perfectly adapted to the energysaving concept of low-energy building techniques: sandwiched between the stove storage block and the outer casing there is an absorber jacket inside which circulating water can absorb up to 50% of the heat from the stove for use via the central heating system. This reduces the direct release of heat into the ambient air, which makes sense in rooms requiring little heating. The absorber jacket is sufficient to heat ancillary rooms without the need for chimney outlets or additional heating systems, and installation costs are very modest. Thermostat valves ensure optimum heat distribution. The pump and safety technology required for the stove water circuit requires very little space and ensures a correct flow rate at all times. Water for use is heated by a boiler or other system. The heat exchanger is located immediately under the outer casing, not in the flue, which lessens wear and tear on the materials and keeps maintenance costs at a minimum. An additional source of heating in conventional builds. If you have not built or renovated to low-energy specifications, a T-LOFT PLUS heat storage stove provides an excellent addition to your existing central heat ing.
This is confirmed by Christian Völlmin, a qualified engineer and project leader of a study on small wood-fired stoves: "We have lots of inquiries for exactly the characteristics of this stove. Lots of customers want a stove as a supplementary source of heat. Today's chimney and woodburning stoves are often outsized in terms of their performance, resulting in overheating. That can't happen with the T-LOFT PLUS, because it can be connected to the central heating system at little extra cost, thereby ensuring that excess heat is distributed around the house to optimum effect." With conventional builds, which require more heat, the T-LOFT PLUS is perfect for heating closed ancillary rooms (e.g. bathroom, bedrooms, office or workshop), providing a cost-effective alternative in the shoulder season or a useful addition to conventional heating systems in the winter months.


Comfort and heating requirements - an individual decision

Individuals vary greatly in their perception of comfortable heating levels. That is why it is so important to start by determining the building heating requirement before deciding on what type of heating to opt for. Wood-burning systems are fun, but do involve some work: the wood has to be transported, cut and properly stored. The T-LOFT PLUS is an economic stove: used as the sole source of heat in a low-energy house, it will burn, on average, one to two loads of wood a day, which is equivalent to between 1,200 and 2,400 kg (2,5 to 5 steres) of wood a year. Your effort will be rewarded with a crackling fire and a cosy living area.
And remember: the T-LOFT PLUS diffuses pleasant, healthy radiant heat for some ten
hours - long after the fire has burned right down.
