Your advantages

Icon Energeeffizient

Maximum energy efficiency

Heating accounts for 75 % of our energy consumption. Heating with the HÖLZLI is particularly energy-saving and cost-effective.

It has an efficiency of over 80 % and has been awarded energy efficiency class A+. In addition, the material used, i.e. fireclay, has a high heating capacity. This, together with well thought-out supplementary heating flues of approx. 3.20 m in length, make the HÖLZLI particularly efficient.

This results in long heating intervals in which the fuel is utilized to the maximum. For 6-8 hours of heat, it is sufficient to fire the stove once with only 3-6 kg of wood. This is not only easy on the wallet, but also convenient and sustainable

Icon Qualität

High quality and durability

Homes are often passed down through generations. Accordingly, foresight is required – also when it comes to the question: “How do I heat?”. The HÖLZLI is made of fireclay of the highest quality “made in Germany”.

At Wolfhöher Tonwerke, we do not only ensure that the material has optimum thermal properties during production, but also attach great importance to high quality and durability so that they can withstand frequent temperature changes without cracking or expansion joints.

A HÖLZLI can therefore be enjoyed for a long time – often also for future generations. Also because heating with wood is up-to-date and does justice to the energy transition.

Icon Individuell

Individuality

What is particularly beautiful about a handcrafted stove is that it offers almost endless design possibilities. Thanks to the modular design of the HÖLZLI, the shape of this stove is fixed, but you can still choose the material and color of the outer shell individually and according to your personal taste. Thanks to its minimalist, timeless design, the HÖLZLI can be integrated into any interior style – whether modern, elegant, traditional, industrial or solid.

The HÖLZLI is ideal as additional heating in the transitional period, for low-energy houses and for smaller living spaces.

Icon Gesund

Health and well-being

Dry air has a negative effect on the airways, eyes, skin and hair. This is not an issue with a heat saving stove made of fireclay! Conventional radiators or cast iron Swedish stoves heat the room by heating the air flowing past them. And unfortunately also dry out the air in the process. A basic stove made of fireclay (such as the HÖLZLI), on the other hand, heats the room through so-called “radiant heat”. This does not require the air as a transport medium, but transmits the temperature directly into the interior by means of long-wave electromagnetic waves. This does not only feel good, but is also healthy.

With the HÖLZLI, you can create a balanced, healthy and natural indoor climate.

Icon Nachhaltig

Sustainability

Heating with wood is an environmentally friendly solution that makes a major contribution to the energy transition. Wood is a regenerative energy source whose combustion only releases as much CO2 as was absorbed during its growth and would also be released during the natural decomposition process. It goes without saying that renewable raw materials should also be used as efficiently as possible.

This is guaranteed with our HÖLZLI. It has an efficiency of over 82% and has been awarded energy efficiency class A+. The combustion process of our HÖLZLI is very clean and low-emission. Thanks to state-of-the-art combustion technology and optimum air control, the fine dust values of the HÖLZLI are below the specified limits.

Versions

HÖLZLI Versionen Blendrahmen

The two versions of the inner lining of the HÖLZLI:

There are two inner lining versions for the HÖLZLI:

OI/30 means the inner lining is ideally suited for an outer shell of 30 mm thick fireclay plates.

With the OI/60 version, the stove door has been moved 30 mm towards the front. This provides sufficient space above the door for a 60 mm thick outer shell (e.g. stove tiles) which is then flush with the door. However, it should be noted that only a 30 mm thick plate or tiles without a framed body can be used underneath the door for both versions.

In case the standard door frame is no longer sufficient for the installed and designed outer shell, a deeper door frame is available as an alternative.
