Water Infrared Heater WH

The WH units designed for universal installation in all living and working areas. The dimensions, the power range, the use of standard control elements and the hydraulic connection are compatible with existing convection heaters such as plate radiators can replace them.

Construction of WH units

WH unit consists of a set of tubular exchangers and a reflecting surface for electromagnetic waves -focus. The heat exchangers are wound in the form of a cylindrical spring and are hydraulically connected by pressing passages to the distributor and collector of the radiator. Heat exchangers are made of AL alloys without surface treatment and are designed to generate and reflect electromagnetic waves. Focus is made of AL sheet without surface treatment, it is placed behind heat exchangers and serves as a reflection of electromagnetic waves.

Advantages of WH water heaters

1 Minimum weight and small water volume

Minimum weight and small water volume allow a quick response for energy efficient use of heat gains during the heating period in passive objects. This significantly saves primary energy consumption and energy costs compared to other heating systems. In cooling mode, the rapid reaction capability allows continuous regulation of the water supply above the dew point of the air and maximizes the useful cooling capacity of the system.

2 One system

One heating and cooling system significantly saves investment costs compared to two separate systems.

3 Universal application

Universal application for all living and working areas .WH units can be installed on the wall in horizontal and vertical positions. Vertical position significantly reduces the installation space for the units.

4 Shape and dimensions

The shape and dimensions of the radiator are adapted to replace conventional convection heaters or panel radiators. They allow radiant heating and cooling of existing buildings without the need for construction work and without the need for new wiring.

5 Silence

In comparison with WH fancoil units, the bodies contain no electric motors, fans, filters and do not consume any electricity. They are silent, do not whirl dust and are easy to maintain by the owner of the building. They do not require special service and the cost of these activities in the future.

6 Affordable

They are an affordable solution for economical heating, comfortable and safe cooling for the general public. The system is safe by its impact on human health during cooling, but also in relation to eventual dew point. When the dew point is reached, there will be no system crashes, as it can be with radiant systems built in the wet way or drywall ceilings.

7 Ceiling installations

For ceiling installations, the radiation ratio ϕ makes it possible to use higher surface temperatures of the infra-red radiators WH and thus higher outputs compared to surface radiant systems.

8 The best price/performance

The cost / performance ratio of the building and the thermal comfort rank these bodies at the forefront of the radiant systems group.
