H 2O Fireplace inserts | Tiled stoves

The sources of all life – nature provides them. Obviously not as directly as shown in the photo, but pictorially only. The wonderfully visible open fire heats the “cold” water from the buffer via the water heat exchanger integrated in the fireplace insert. The hot water is then returned to the buffer. The heat can then be used in the house in a decentralised manner, either via the heating element, the underfloor heating or for bathing/showering.

You may be thinking that such a fireplace with H2O technology requires more space than a hot air or storage heater. We can assure you here that there is no space saving in the installation room at such a high energy yield.

Simply a great idea for heating with energy efficiency and environmental awareness • 25-80% water heating contributions • 78-85% firing efficiencies • Decentralised heat supply • CO2 neutral

Obviously this always depends on the conditions. But if you have a sufficiently dimensioned buffer together with all the other important components of a modern central heating system, it is worth comparing it with a “normal” hot air fire place, perhaps not considered over a year but certainly over the period of use of the fire place. Not forgetting the pleasure and cosiness of the visible, protected and efficiently used fire.

In addition to the water heat supply the fireplace insert supplies comfortable radiant heat to the installation room.

The question remains: “Is all this affordable?”

Introduction 2|3

I M A G I N E , ... your hot water comes from thee Stove. Not possible you think? Far from it, for a high proportion of our daily direct or indirect water consumption is heated water. All the more important is that you convert existing energy into hot water. For whether a hot bath, a cleansing shower or simply the comfortable warmth for your feet through the underfloor heating, everything is supplied with hot water. And that is every day. In these times of ever depleting resources, it is therefore extremely important to handle raw materials intelligently and thoughtfully. Minimise environmental pollution and make optimum use of existing energy sources. Be aware of your responsibility and heat in an environmentally, sustainable and money saving manner with wood. Heating with wood is always worthwhile.

You could get this, for example, from a Mini Z1 H2O. With firewood at 2.0kg/h you keep a living room of 40m2 of a KFW* 70 house at an indoor temperature of 20°C by radiant heat from the fireplace. In addition you can, with the water heat exchanger, either: • increase a 300l buffer from a water temperature of 40°C to 56.1°C or • shower for 8.4 mins at a water temperature of 39°C, or • draw 160l of water with a temperature of 39°C in 1.0 bath filling

This is how it is done. The example construction briefly illustrated below was converted to a combined solution of solar and wood heating in the early 1970’s from a gas-operated heating boiler. The open fire place in the living room was replaced by a Varia 1Vh H20 XL fuel cell with a water heat exchanger. Optically it is still a fuel cell with a large sight glass, and in terms of power a genuine power station.

Interruption of the open fire place with a smoke flue.

Plastering of the raw tiled wall after reconstruction is completed.

Core drillings through the basement ceiling for the separate combustion connection and the feed and return pipes.

The fireplace insert is located in the living room.

You can see in the chronologically illustrated flow that the cost of a stove solution with a water heat exchanger involves minimal extra expenditure and can be incorporated invisibly into the existing system. Thus with careful planning the installation can also be carried out quickly and cleanly by hand, as if you had chosen a conventional solution.

Piping of the fuel cell for the water-side connections and alignment of the flue pipe outlet.

The final position is reached; the connections are located above the core drillings; the insert can be aligned.

The feed and return pipes are laid on the basement ceiling above a ceiling opening and are connected to the fuel cell.

The flue pipe connection is made, the fuel cell can now be built up with bricks.

The plastered superstructure is carefully removed and inspected.

EARLY PLANNING NI IS SIMPLY BETTER. Heating systems for houses usedd to be simple. A fuel, a burner and the heating system was complete. Because of the increase ass in energy prices and ecological sensitivity, simple solutions are now rarely considered. Very oftenn you now have a combination of a wide variety of heating systems, always individually matched to your o own life situation, position of the house and architectural style. Depending on whether your water-conducting e fireplace insert, your Aquabox or your filed stove heating insert is used as a system m for heating the whole house, water heating of for backup heating only, different demands are made dee on the heat load for the house, its production and distribution. In cooperation with the stove fitter e and the heating installer, you should clearly set out your requirements and ideas. The specialists st will then put together for you solutions that exactly match your living and life style. It may be necessary to determine m the heat load for your house • For anyone who knows the average e er energy requirement of his/her house at peak times therefore knows what he/she needs. Forr this purpose the heat load is calculated according to EN 12831 on the basis of the living area. Thee quantities of wood per day and year are obtained from this value. Which heat exchanger is best stt for you? • This must be decided from case se to case, for it obviously depends on the building material but also on the building geometry aand your living habits. It is important here to have a wide choice in balancing of the proportion of room heating and water heating to permit po individual daptation. Regulation and control as a ccontribution to environmental protection? o • The higher the heat load to be ssupplied the more important is the electronic regulation of the combustion for best combustion economy with a time saving in firing work. u

AQUA SQUARE, PRACTICAL, ADAPTABLE. The most impressive feature of the Aquaboxes is their flexibility when also used on numerous fuel cells with different geometries. As in the case of the water-jacketed fireplace inserts, heat is extracted from the rising fuel cells in an attached water heat exchanger and supplied to the buffer for relieving the heating system. You therefore boost your hot water production, relieve your central heating system and at the same time supply additional rooms with heat. Varia 2Lh + Aquabox

The Aquaboxes are available in 2 versions with different water storage capacities. The facts are therefore obvious: They save power, oil or gas and are light on your purse. The Aquaboxes almost always fit.

Their advantages • they can be used on 40 fireplace inserts with a wide variety of window shapes and dimensions (Building Permit issued by DIBt no. Z-43.31-198) • efficiency on the water side approx. 25-40% of the nominal heating output • no annoying cleaning or inspection openings • cleaning through the combustion chamber • low space requirement • environmentally friendly • low energy costs

The so-called Building Rules Lists of the NBR provide information on which standards apply to building products. Three types of products are distinguished: • Regulated building products comply with the technical provisions of the Building Rules List or only deviate slightly from them.

• The general Building Permit is revocable and is granted for a specific period, generally five years. • The general Building Permit renders individual tests unnecessary. Architects and owners can plan and build creatively, innovatively and at low cost without delays and uncertainties, which may lead to an agreement in the individual case.

• Unregulated building products deviate considerably from the technical provisions of the Building Rules List, or there are no technical building regulations or generally recognised rules of the art for them • Other building products are not contained in the Building Rules List, although there are generally recognised rules of the art for them. Manufacturers must demonstrate the suitability of unregulated building products and designs:

51 kg

This is possible by means of a general Building Permit. Building Permits are granted exclusively by the German Institute for Building Technology in Berlin (DIBT), a jointly established federal and regional institute.

MINI IN THE DIMENSIONS MAXI FOR HOT WATER Water-conducting fireplace inserts Mini Z1 H2O – which show effect. In our Mini’s economy is what counts above all else. Obviously an attractive, visible fire is important, but the larger the window the greater the heat loss through it. Therefore, for all those for whom the water-side power is the most important consideration, our Mini’s provide the maximum water power. For passive house owners who have an extremely low power demand in the installation room, there is the Mini with a nominal heating power of 7 kW. Due to double glazing and infrared mirroring, most of the energy remains in the combustion chamber. The radiation in the living room is reduced to a minimum.

Their advantages: • Maximum economy with 78% or 80% water heating contribution • Maximum effectiveness with over 85% efficiency • Double glazing and infrared mirroring • Maximum environmental compatibility with a great fire experience

MODERN TRADITION Water-conducting storage miracle Nova/Renova Previously the product “tiled stove” had to have something to do with tiles. There were no heat exchanger and storage masses other than tiles. According to Wikipedia tiles are burnt, glazed earthenware slabs for tiled stoves. Today these fire places are still called tiled stoves either because they are still genuine tiled stoves, it is a collective term for different designs, or the heating insert has been tested as a tiled stove insert. The principle of operation has remained the same, except that there are not always visible tiles on the installation.

Their advantages: • Water heating contributions of 51% - 64% • Renovation of old hot air stoves with modern exactly fitting alternatives • Variable system between an accumulator in series connected flues / ceramic and water • Modern all-house heating systems with the appearance of a bygone classic

Nova/Renova 22|23

Nova and Renova stove heating inserts. Wood is burnt as economically as possible in a fireplace insert. The radiant heat generated above the sight window passes directly into the installation room. The hot flue gases formed are not fed directly into the chimney but, according to the individual requirement, are either • cooled in the series-connected ceramic or metal reheating surfaces and storage masses, in order to discharge into the room the stored heat extracted at intervals from the flue gas, or • heat, by means of a water heat exchanger, the heating water in a buffer, thereby relieving the heating system and making the heat available elsewhere in the house by means of heating elements or under-floor heating. There are two variants:

The Nova stove heating insert is provided for the new building of a heating system. With its water heating contribution of 64% and its double glazing it is ideal for generating as little heat as possible in the installation

room with maximum backup heating if necessary, but naturally until you decide that the radiation temperature in the room is comfortable and adequate.

The reliance on the word “Renovate” is intentional. This is an exchange unit for existing fire places. The dimensions are intended for easy exchange of existing pure hot air appliances. But here we no longer offer a pure hot air version but only the variant with a water heating exchanger. The extra cost, compared to a hot air unit, results from the use of a feed and return water pipe and two safety connections based on corresponding existing heating technology.

Depending on the installation situation it may be that in the case of the Renova heating inserts a built-in frame or niche frame already exists. In these cases there are bezels of modern design for inserting into the existing frame.

Nova N 2.0 or R 2.0

In new building the Nova fuel cell can be installed either with or without a bezel. Here these bezels are placed in front of the installation wall.
