Joyful stoves and hybrid house mates
by Thomas Edelmann
Anyone planning for their new build or wanting to convert a home – by switching the heating over in part or as a whole to hard fossil fuels such as logs or wooden pellets soon finds themselves facing a huge range of different possible options. The ISH trade fair in Frankfurt from March 10-14, 2015, will provide all the details on the construction, technology and design of the latest stoves and fireplaces and how best to use them. As the world’s leading fair for bathroom design, building, energy and HVAC technology and renewable energy, it brings together the key providers in the field.
Anyone deciding to heat using wood should assess what will be useful and meaningful in their situation. What functions should the stove have in the home? Is the idea merely to warm the body and soul now and again and introduce atmosphere in the form of flames? Is the idea to use it as the constant main source of heat or only as a standby?
If one goes for central heating and firing it with renewable fuels, then the appliance tends to get located in a heating/technical room. Its external shape may not be completely irrelevant, but subordinate to standalone stoves that take a place in a living room. By contrast, the appliance in the cellar must have reliable, user-friendly controls and maintenance must be easy, and if possible the unit should not take up space.
Between nostalgia and smart technology
Things are again different when it comes to storage heaters and basic stoves, such as the famous old tiled stoves. Once condemned as a technological relic of a past age and often ripped out as a consequence, such stoves are re-entering interiors either as reconstructions of the original or as the original reassembled in a new place, providing heat for the home. Many specialist service providers rely on current formal idioms when designing and building such stoves. This goes as far as the outer cladding – where materials such as leather, concrete or stamped clay are even used. Traditionally, the flames in tiled stoves dance away behind closed doors. The stoves are so liked because of the pleasant radiant heat they provide and continue to radiate even hours after the fire has gone out, with fireclay bricks retaining the heat – which adds real weight and mass to the stoves. Another special type are stoves and fireplaces that rely on water technology, such as those made by Spartherm and Oranier, which provide a certain proportion of the warm water needed for the radiators in the other rooms. This segment is also rapidly being conquered by smart technologies. Some appliances, such as those by Rika, have digital controls, meaning you can decide how much heat gets injected into the heating cycle or the storage mass of the stove. Despite the easier digital controls, much of the effort that is required to lay the fire is initially unusual for us spoiled users of central heating systems.
The fire as an experience for the senses
Many makers are adapting basic stoves to modern interiors by creating hybrid models that as compact storage heaters combine the advantages of the latter with the typical properties of an open fireplace. These hybrids are lighter and once the fire has gone out radiate little heat. But the fire is always visible behind the glass.
Hunting for the new
Two years ago, at the ISH the manufacturer Buderus presented retrofit elements with a glass door for existing heating systems – designed by none other than Stefan Diez. At this year’s fair, Buderus and Diez are going to be showcasing new standalone stoves. Not only the outer shape, but also color issues and user interface details played a special role for Diez. How to change the conventions? And how can the design of the stoves be calibrated better to meet contemporary living interiors? Because although the industry makes countless shapes and detailed solutions available, from purist units to playful decorative surrounds, precisely among the high-end stoves certain basic types and material and color mixes predominate: for example round units with cast-iron components in anthracite. Products differ from one maker to the next in terms of the modules for the individual components, and how the brand is incorporated or presented. And specifically those details can best be compared and evaluated at a fair that brings together the main manufacturers in the segment, and this the ISH in Frankfurt most definitely does.
