Leading manufacturer of measuring devices for the collection of heat and water consumption.

Heat Cost Allocators:

What is a heat cost allocator?

A heat cost allocator measures the relative heat consumption share of a radiator. For this purpose it is attached directly to the respective radiator. The method of the metering process is to determine the temperature difference between radiator and room temperature. The actual energy consumption is then calculated using a conversion table with heat transfer values that exist separately for each radiator type.

To compensate for measurement inaccuracies, the heat cost allocators “know” the difference between summer and winter. Both the single and dual sensor models from QUNDIS offer you the most accurate metering values possible, depending on type.

The different types of heat cost allocator.

The various Q caloric heat cost allocators from QUNDIS differ in the number of their temperature sensors. Single-sensor models are simpler, as they do not record the room temperature separately, but are based on a fixed value. 2-sensor models measure the radiator temperature directly on the unit and the room temperature at the optimum location. This is why the 2-sensor models from Q caloric offer even more precise metering values. In addition, there are remote sensor models, with which the heat emission of very special radiator types or radiators which are difficult to access can be recorded.

Our electronic heat cost allocators represent the highest technological standards and offer the largest range of applications worldwide. Thanks to our comprehensive database of heat transfer values (KC values), the Q caloric model can be used on almost any radiator.

Due to the standardisation of the radio telegrams and the readout files, as a measurement service provider you offer your clients (house administrations, owners, etc.) the greatest possible independence (from devices, manufacturers, etc.).

In addition, you can offer tenants a high degree of transparency when measuring consumption, as they can also read the consumption according to the standard and product scale directly on the device themselves.

BENIFITS

Works with all common radiators

our comprehensive KC values database covers almost every type of radiator on the market. Therefore, the Q caloric heat cost allocators can be applied with practically all radiators.

Read-out processes as required

Our heat cost allocators are available with or without radio function, as well as with or without infrared interface. This allows you to set up the readout processes according to your requirements.

Secure

Fast identification of attempted manipulation.

Further processing of data

Thanks to the standardised radio protocols and file formats, the consumption data can be easily exported and processed further by the standard billing programmes used by metering service providers.

Always ready for readout

Because the heat cost allocators are equipped with C-mode radio communication, the devices can also be read out in mobile form 365 days a year. Access to the apartment is not required.

Exact metering values

Thanks to the independent readout functions and a maximum measurement tolerance of 2 percent, QUNDIS heat cost allocators provide highly precise metering values.

More transparency

On request the Q caloric heat cost allocators offer a display of values according to standard or product scale. This gives end consumers a very transparent way of tracking their energy consumption on the basis of their bills.

Heat Meters:

What is a heat meter?

A heat meter measures the energy consumed in the supply of a certain amount of heat or cooling. The device is mounted directly in the pipe network.

The process behind it is quite simple: Water is heated in a heating system. When a radiator is turned on, this water flows from the heating unit to the consumer through the heating circuit at a certain flow temperature. Each active radiator emits the heat of the heated water to the surrounding room. The water cools down and continues to flow behind the radiator in the return pipe. The temperature difference between flow and return is measured by the heat meter. The unit calculates the energy consumption from the temperature difference and the amount of water that has passed through.

This makes our Q heat series heat meters extremely versatile.

Radio or M-Bus system

Modern interfaces to our radio or M-Bus systems facilitate the recording of consumption data for the metering service. The meter is parameterised via laptop using the IrDA interface. Installation instructions can be found here.

Metering from 4 seconds

Our ultrasonic instruments deliver recorded values with a fast metering cycle of 4 seconds. The Q heat 5 basic impeller meters record in this mode every 6 seconds.

Very simple seal assembly

Thanks to the Selflock seal, your fitters no longer have to install their own seal. In addition, a serial number is already printed on the seal. This makes the work much easier.

A wide range of varian

Suitable for heating, cooling, solar and hot water systems, and available as both screw-type or metering capsule variants.

Suitable for glycol mixtures

The Q heat series heat meters can also be used to record the consumption of solar heating systems.
