A New world in Domestic Heating

Housing

With Conflux' self-limiting PTC heaters a new world in domestic heating opens up. Now you can design heaters which keeps a constant temperature of your choice, they cannot overheat, they most often require no regulating electronics and they can be covered with any material like clothes, blankets, wall paper etc. This gives you freedom to stop the cold draught already at the window and/or the air inlet, and place the main radiators anywhere you want in the room and with any design.

Conflux has developed novel heating concepts for suppliers of various types of domestic heating. The new concepts include heated air inlets, heated window sills, artistic electrical radiators, designed towel heaters, liquid filled radiators etc. Please contact us for more information.



Executive Summary

Conflux’ unique heating elements enables heating of houses in a revolutionary new way. You will be able to provide your customers with new heating functionality, which enable unique products that have not been previously possible. Together, we can extend your business and create new business on existing and new customers.

The new heating products include:

  • Heated air inlets: Heat the air on its way into the house. This reduces the heating power needed in the house and eliminates cold draught from the air inlets.

  • Heated window sills: An invisible low power radiator placed in the window sill reverses the airflow and eliminates the cold draught from the windows. This increases your comfort and eliminates the need to place the heating radiators under the windows. They can instead be placed anywhere in the room and designed more freely.

  • Designed radiators: More design freedom in radiators, e.g. to make them invisible, make them artistic etc. and be placed anywhere in a room. The radiator cannot overheat and can be covered in insulating material, embedded in walls etc.

  • Towel heaters: New towel heaters which can be water (+ glycol) filled instead or air or oil, or just designed metallic plates. The temperature is more comfortable, they cannot overheat and they consume less energy.

  • Heated floors: 1 mm thin floor heating which can be placed directly under the tiles or other floor material. The heaters are powered with low voltage and can be cut to shape for easy mounting. The heaters are self-regulating and automatically reduces their power under mats and furnitures. They automatically increase their power in cold spots. The temperature of the floor is controlled with a normal dimmer and no regulating electronics or overheat protection is needed.

Electrical radiators with Conflux heaters are self-limiting and cannot overheat. They can be covered in insulating material. They require no overheat protection.

The new radiators apply better with the new EU regulations as the power produced is self-regulated to the ambient conditions and reduces large power variations. Self-limiting and self-regulating radiators will give you a strong competitive advantage in the future.

Self-limiting radiators

Conflux has built and tested different self-limiting radiator designs; classical radiators, vertical designed radiators, heated window sills, tubular towel heaters, heated air inlets etc.

Designed radiator
Figure 1. A classical radiator with a self-limiting Conflux heating element.

This is a classical design which can be used as a normal radiator under windows, or designed to any shape and be placed anywhere in a room. In its basic configuration it is a metal plate with good thermal conductivity with one or several Conflux heating elements mounted directly on the metallic plate.

Designed towel heater

The designed radiator is a vertical radiator with larger area than the previous radiator. It produces a strong up-going convective air flow between the radiator and the wall. It can be combined with hangers for towels or clothes. In its basic configuration it is a metal plate with good thermal conductivity with two or more Conflux heating elements mounted directly on the metallic plate.

Heated window sill

The heated window sill is an invisible radiator which can be integrated in the window sill. It can be encapsulated in any material; wood, stone, MDF-board, paint etc. Its primary use is to prevent cold draft from the window by changing the airflow close to the window to be rising instead of falling. Tests show that this requires only a limited heating power per window. It can be covered with newspapers, flower pots etc. without overheating.

Liquidfilled heater
Figure 4. A tubular towel heater filled with water and a self-limiting Conflux heating element.

The tubular towel heater is filled with water (+ glycol, if needed). The heating element is swimming in the water and keeps it at a constant temperature. The self-limiting nature of the heating element prevents the water from boiling without any regulating electronics or overheat protection. The tubular towel heater can either be an open geometry with a heating element all along the tube, or a closed loop with a shorter heating element which heats the water and drives a circulation of the water. It keeps a temperature and does not burn your skin.

Heated air inlet
Figure 5. A heated air inlet with self-limiting and self-regulating Conflux heating elements.

The heated air inlet is a novel way to heat houses. It heats the incoming air before it enters the room. This reduces the heating power needed in the room, and prevents cold drafts from the air inlets. The self-limiting nature of the heating element makes it possible to incorporate the heater in the air inlets without risk to overheat them. The self-regulating nature of the heater allows the heater to be used without any regulating electronics. Just mount the heater in the air inlet, connect it to power and let it go. Optionally, it can be switched off during the warm season.

Advantages of self-limiting radiators

Self-limiting radiators cannot overheat. They can be covered with insulating material without any risk of overheating, and without any overheat protection.

Covered radiator
Figure 6. A self-limiting radiator covered in a duvet without any overheat protection.

Even if the radiator is fully covered in a duvet the temperature of the radiator does not rise to dangerous levels due to the self-limiting nature of the Conflux heating elements. The heating element can detach, fully or partially, from the object it is attached to without overheating. In a liquid filled radiator, all liquid can disappear from the radiator without risk of overheating.
The room temperature is controlled in a similar way as for normal radiators, even though the regulating logic is simplified by the intrinsic self-limiting and self-regulating properties of the heating element. The room temperature is measured at an optimal position in the room, or centrally in the house, and each radiator can be controlled remotely. The remote control system switches on and off the radiator with arbitrary time intervals, which can be long to minimize the EMC emission. The radiators can optionally be regulated by regulating the voltage to the radiators or the air flow through the radiators. The self-regulating nature of the Conflux heating element reduces the power of the radiator if the room is fairly warm when the radiator is switched on, strongly reducing the power fluctuations when radiators are switched on and off. This applies well with the new EU regulations.
