OHA URHE “Ultra Radiant High Efficiency” is a technologically innovative gas combustion unit for heating large spaces.
OHA URHE is a condensing radiant heating system, flexible in its installation. The coupling of the various elements has been studied to guarantee maximum thermal efficiency at ground level, reducing heat losses upwards to a minimum, and maximum safety: the system has a depression operation with respect to the environment, controlled and managed by an innovative electronic control, the whole system is made with the use of very high quality materials and equipped with a forced discharge of the products of combustion. In the OHA URHE-R version, the system is equipped with a condensation heat recovery unit that can significantly increase the already very high efficiency values.

HOW DOES IT WORK?

A microprocessor calculates the power capacity of the motor needed by OHA URHE burner, in order to deliver the correct power able to satisfy the real thermal requirements of the building to be heated. The inverter, included in the OHA RHE burner, modulates the electrical consumption of the fan, keeping the temperatures of the fumes constant and eliminating the overshooting. Thanks to the climatic regulation of OHA URHE, the temperature of the fumes flows more smoothly. In this way the power excesses, which cause continuous ignitions and shutdowns of the burner (overshooting effect), are avoided and the consumptions are strongly reduced.

Fully running system with OHA URHE = COMPLETE MODULATION

Homogeneous heat = Max performance

ADVANTAGES

• A noticeable reduction in electricity and gas consumptions
• An optimal combustion efficiency, regardless of the length and configuration of the radiant circuit.
• OHA RHE technology allows to uniform the heat along the whole radiant circuit, heating homogeneously the environment.
• Silent and healthy
• More flexibility of application: OHA radiant strips are suitable to heat buildings with particular shape, thanks to the ducts that can be joined and fitted to any architectural geometry.
• Gas line and burners installed outside the building to be heated
• Ideal for high height and large surface areas with large heat losses
• Ecological and environmentally friendly, low consumption and low smoke emission levels
• High efficiency and condensation models
• Flexibility and versatility in the realisation of the internal heating circuit
• Possibility of creating zone systems with partial or differentiated heating
• Simplicity and rapidity in installation and maintenance
• Quiet and healthy operation
• Rapid commissioning of the rooms to be heated
• MODBUS interface for supervision systems

COMBUSTION UNIT TECHNICAL FEATURES

Patented and EC certified suspended thermal unit for external installation, featuring:

• A high efficiency gas burner, with a fan for recirculation and expulsion of thermal vector fluid
• An integrated electrical control panel, complete with electronic equipment, safety systems and temperature and depression sensors
• Protective casing with self-supporting sheet steel panelling painted with thermoplastic material

NEW RADIANT CIRCUIT

Thanks to the new wider and more efficient radiant circuit we will have:

• Better RF (Radiant Factor - IMQ report) ground radiation efficiency
• Better seasonal energy efficiency with values higher than the minimum limits required by European Regulation (EU) 2015/1188
• Better environmental comfort thanks to the automatic modulation of the system that always maintains the ideal set temperature

The new combination of URHE tape evolutions L= 1100mm allows for greater diffusion of the heat emanating from the circuit tubes, and the larger reflective surface area further increases the overall efficiency in diffusing the radiated heat of the system.
