HAPLAN GmbH Munich, 27 March 1986 Wiesbaden str-pr 15 050/210 Mobile room heating

The present innovation relates to a hot-water heating system comprising a heat source such as a gas burner and which is installed in particular in caravans, campers, mobile homes or boats or similar mobile spaces.

Heaters for caravans are well known and are also used

during the cold season, a caravan as a mobile

holiday apartment. The existing systems

For this purpose, use a gas oven*, for example whereby the heat in the room is circulated with the help of a fan motor

distributed, or a household member known

Hot water heating system with radiators. Due to the

Due to the limited space in such mobile rooms, these radiators are very small, which means that a high temperature level is required, which results in high energy costs. As a result of the hidden arrangement of the radiators, good convection is not guaranteed; the result is an uneven

Temperature distribution in the room. The aim of the innovation is to create a ready-to-install

term ₅ with a liquid heating medium, preferably

Water, powered heating with a heat source, such as

a gas burner, which can be easily integrated into mobile spaces and at a low

temperature level works energy-efficiently. The solution

The innovation is that in the soil and on the

Large-area heating plate elements are arranged on the inside of the walls. These are made of flexible plastic and have numerous parallel channels inside, which end at or near each end in a pipe that is also made of plastic.

Large plastic panels through which the heating medium flows achieve a large exchange surface, and the flat design makes it possible to install the heating panels behind panels or the backrests without great effort. A non-slip design enables the use as underfloor heating. A number of possible designs are available to the

Subclaims can be found.

Further details, features and advantages of this innovation can be found in the following description of an exemplary embodiment shown in the drawing.

The hot water heater 10 shown in Figure 2 for exemplary use according to Figure 1 in a caravan trailer consisting of the heat-emitting elements 14 and 16 receives heat from a heating arrangement 12.

The heating arrangement 12 is located in a room R outside or inside a caravan C (Fig. 1) and consists of a gas-fired boiler 20. A burner 21 is supplied with fuel from a gas bottle 26. For stationary operation, a heating rod 24 that can be electrically connected to a mains can also be provided in the system. The heating circuit is moved by a pump 22. A heat exchanger 18 for hot domestic water preparation can be inserted into the circuit.

From the heating arrangement 12 in the gas tank storage compartment R or an appliance container) of the caravan C, a flow line 28 and a return line 30 lead through the wall into the interior of the caravan C.

There, the medium, a mixture of water and antifreeze, which was previously heated to a desired low temperature level by the heating arrangement 12, is fed to several wall plate heating elements 14, a floor plate heating element 16 and the domestic water boiler 18.

A three-way thermostatic mixing valve 32 can be used to divide the inlet volume flow of the heating fluid between the wall heating panels 14, the floor heating panels 16 and the domestic hot water boiler 18. A thermostat 34 connected downstream of the three-way valve 32 can be used to regulate the flow temperatures for the floor heating panels 16 in stages relative to the wall panels. The respective end temperature of the consumer is regulated by setting a specific volume flow of the heating fluid. The temperature of the wall panel heating elements is determined by the position of the three-way valve or ball valve 32. Another thermostat 34 divides the return flow into the flow and into the boiler 20.

All consumers are connected to each other and to the heating system 2 by flexible hoses (e.g. temperature and glycol-resistant cooling water hoses). A filling and draining valve 38 is provided in the circuit, with the free nozzle leading out of the caravan floor. An expansion tank 40

jr is integrated into the cycle.

In the example shown in Fig. 2, the hot water boiler 18 is arranged in series with the plates 14 and 16. Of course, a parallel supply can also be provided.

The wall or floor heating panels 14 and 16 shown in Figures 3 and 5 are extruded, flexible plastic panels with channels 52, as are known from solar heating systems. However, they serve as heating elements within the solar heating system, and here they are used as heat emitting elements 14 and 16, as is new.

These plates 50 are characterized by closely spaced, interconnected water channels 52 of small diameter, which are coated with plastic in such a way that very flat, flexible plates are produced. These large-area, fluid-flowing plates can be used to provide wall and floor heating panels of any size, all of which are very thin and therefore not bulky and are light. The heating medium in the channels 52 flows through these heating plates 14 or 16 over a large area, so that the heat is evenly emitted to the environment by thermal radiation.

Due to the low construction thickness and the connection of the

Wall heating plate elements: thanks to flexible hoses, these heating elements can be screwed or glued vertically to the caravan wall behind seating groups or other cladding elements, even retrospectively, in a space-saving manner.

The panels 50 can be produced endlessly at low cost. For the floor panels 16, specified lengths (as per Fig. 3) are cut off, and the channels 52 open at the front edges 54 are surrounded by a slotted pipe or square pipe 56, which is pulled over the front edge 54 with the open slot and extruded. A collecting channel 58 is created in the pipe 56" in front of the open channels 52, which leads the medium to the nozzle 60 or away from it.

A wall element 14 can be constructed differently according to Fig. 5 and 6. The plate 50 is closed at the front 64 and a slot 66 is made transversely to the channels 52. A tube 68, also slotted, is placed on the open slot 66 and ends in the connecting piece.

The floor plate heating element 16 is manufactured in a non-slip design and is spread out over a large area across the entire caravan floor without having to change other dimensions such as those of the doors due to the small thickness of the element 16. It can be stiffened in the same way as the wall heating elements 14. In the delivered state, it can be rolled parallel to the channels 52.

Hose clamps are used to connect the hose to the heating element, and space-saving angles are available for laying corners.

To ensure even heating of a caravan, you should calculate with 1 square meter of panel element per meter of caravan length.

The heat output of the panels per square meter is lkw(/sqm) for this wall heating element 14 and for the

Floor panel heating element 16 0.69kw(/sqm).
20

For this purpose, a temperature of approximately 55°C is set in the wall panel heating elements 14 and a temperature of approximately 27 ^° C is set in the floor panel heating element 16.

The heating is controlled electrically or electronically.

If the caravan is parked on a campsite where cheap electricity is available, an electric heating cartridge 24 can be used to heat the heating fluid instead of the gas-fired gas boiler 20.
