Materials

Bodies of the fireplace inserts are made of P265 GH grade heat-resistant steel, used for the production of pressure pipes operating at high temperatures. Compared to standard structural steel, refractory steel is enriched with Cr and Ni. The material is also more chemicaly pure. This ensures long service life and mechanical stability under temperature stress.

Double glazing
Double glazing

Double glazing

The double glazed doors corresponds to current building standards. Energy requirements of houses as well as individual rooms are lower than ever thanks to modern standards of the thermal house insulation. The double glazing improves the insulation qualities of the door and reduces the heat amount radiated to the room through the door. The room with lower energy requirements is not overheated in this way.

Paint

UHT 600 Hydro is a colour of the highest quality of the Senotherm series. This is the colour with which are painted the visible parts of our products. The paint is cured at room temperature and the unpleasant odour is avoided. It is also resistant to mechanical damage. The other components are painted with the second best quality colour, with UHT 600. This paint doesn’t smell and smoke even at the first burn-up.

Mechanism of the liftdoor
Mechanism of the liftdoor

Mechanism of the liftdoor

A sophisticated slide mechanism guarantees a permanent quiet and light movement of the door. The door slides in a closed chamber over the door and does not restrict the living room in this way. The precise movement of the door at high operating temperatures is guaranteed by eight bearings which are resistant up to a temperature of 350 °C. These bearings move in stainless steel profiles which guide the door movement exactly and permanently. By opening the sliding door it automatically draws out by several millimeters thereby increasing the longevity of the fire cord seals. A spring mechanism presses the door closed into locking position by force of 25 kg and thereby air tightens the firebox perfectly.

Reinforced door profile
Reinforced door profile

Reinforced door profile

The door is a much used moving part where strength and stability are of utmost importance. These qualities are fulfilled by a specially made door profile with the wall thickness of 2.5 mm. The parameter of the door profile strength guarantees stability of the door mechanics in the daily operation at high temperatures. The doors can be ordered in single and double glazing. The seals in the door profile are mounted in a conical groove which holds it in place.

Easy to operate
Easy to operate

Easy to operate

The fireboxes of the HOXTER products are so tight that the fire immediately responds to ever so little a movement of the control lever. High combustion temperature in the firebox does not affect the safety and control comfort. Control elements are designed to be self cooling during the operation. This cooling effect is amplified by using suitable materials as stainless steel. Next to design, Hoxter paid much attention to simplicity of control. They are characterized by pure shapes and intuitive control.

Accumulation rings

Accumulation rings

Additional mass storage significantly increases the heat capacity of the fireplace. Energy stored in 150 kg of HOXTER accumulation rings offers a radiant heat source for many hours after the last fueling. Double layer construction and special inner spiral shape of the rings perfectly conducts the heat from combustion fumes to the mass storage. Simple solution requiring no further power source.

Lining of the combustion chamber

Lining of the combustion chamber

The company Hoxter offers not only the standard light lining, but also the dark lining option is available. This solution is primarily suitable for interiors where the light lining would affect distraction. Shaped parts of the lining are made from colored fireclay mixture. This means, that the visual appearance of the combustion chamber remains colour-stable even when the surface of the lining is accidentally damaged. Fireclay shaped parts of both light and dark shade are burned during the production with temperature of 1100°C. Thanks to this process the long lifespan of the whole combustion chamber is guaranteed.

Removable handle

Removable handle

The removable door handle allows to create a natural undistracted view to the flames. This handle may be used on all products with liftdoors. There is a small rectangle opening bottom side of the door where the handle may be easily placed. The opening is placed near the ceter of gravity of the door. Thanks to this the easy operation of the liftdoors system is guaranted. After the doors are closed the handle may stay on the doors or may be removed and stored into an installed casing.

Door design

Outer glass of the doors may be attached with standard black door bars or with bars made from polished stainless steel. When the stainless steel option is used not only the product stands out but it highlights also the details made from fine materials.

UKA supporting construction and build on frame

UKA supporting construction and build on frame

The supporting construction for the build on frame is assembled on the rear side of the fireplace. This surface is cold because there is a channel for combustion air leading underneath. Thanks to this the supporting construction is not influenced by thermal stress and remains stableThe build on frame is attached to the top side of the supporting construction – not to the upper part of the fireplace inserts, which may be influenced by thermal expansivity. This innovative solution offers simplified build, saving of space and expanses for the external construction at the same time. The weight capacity of the build on frame is 200kg.

Rear feeding

Rear feeding

The advantage of a rear feeding door is a practical and clean contribution. The fireplace glass door offers a spectaculair view of the fire in the living room while the rear door without glass is used to feed the furnace from a utility room or a hallway. The door for the rear feeding is designed not to be visible from the front side of the fireplace. Nevertheless its presence does not reduce a high combustion efficiency and cleanness of the fireplace glazing.
