DHW, i.e. domestic hot water, is a solution that has become a permanent feature of water installations and heating systems in single-family houses and elsewhere. This is a great way to make the most of your opportunities.

What is the DHW sensor used for?
Temperature sensors are technologically advanced solutions whose main task is to monitor and control the water temperature available to the inhabitants of the house. Hot water is one of the ways to optimally use modern solutions and technology, which allows you to reduce your bills. Depending on the type of installation it is in, it enables precise determination of the temperature in the installation or a specific heating device.
The sensor performs the measurement and transmits information, and the boiler controller receives the measurement result and modifies the operation of the heating device, based on the provided data.
The second variant of sensors are the so-called thermocouples, i.e. thermoelectric sensors. It is important that when selecting individual elements, make sure that they are adapted to the appropriate devices and installations. These elements are designed not only to improve user comfort, but also to protect the device against damage. It must be remembered that only optimally matched components will ensure effective and truly economical operation, as well as extend the life of the entire system.
How to extend the DHW sensor?
The hot water provided by the manufacturer is not always adapted to the needs of a specific installation. It sometimes happens that it is necessary to make a modification by extending the sensor. Contrary to appearances, it is not difficult to do, just cut the cable approximately in half and then use the appropriate cable to cut it to the required length. However, it should be remembered that the connections must not only be properly made, but also secured.
You will need to purchase a cable that matches the connecting cable. However, you must be aware that such action will lead to increased resistance, which may adversely affect the precision of the measurement, although not in every situation. The best solution is therefore to consult a specialist who will carefully assess how the cable extension will affect the temperature and, if possible, will perform the task in a professional manner.
Where to place the DHW sensor?
Before choosing the place where the hot water sensor will be installed, it is worth understanding how the water in the tank behaves. When the tank heats the water, the temperature increases and the air, which is denser, moves upwards. Therefore, remember that the sensor cannot be placed too high because it would not have access to hot water to perform regular measurements.
Therefore, the DHW sensor must be properly installed in the installation to function properly. Where? The location depends primarily on the type of sensor you have. Models with a horizontal measuring sleeve are placed at approximately ⅓ of the tank level. This is the optimal place for the sensor to have constant access to the appropriate amount of hot water to measure. The second type are hot water sensors with a vertical sleeve, which is placed in the upper bottom of the hot water tank. In such a model, it is possible to manually adjust the sensor.
DHW sensors in the Onninen wholesaler
The hot water sensor is one of the key elements of the system that allows you to enjoy hot water at home. Onninen's offer includes a wide range of products, adapted to work in various conditions and with various devices. An example is the LG DHW sensor for heat pumps . This is a solution that works perfectly with various devices, except for the high-temperature pump. Using highly advanced measurement technology, it allows you to make precise measurements. Exceptional accuracy, in turn, optimizes the operating conditions of the entire system, helping to reduce electricity consumption. The solution prepared by LG has all the necessary certificates.
An alternative is the offer provided by a brand valued among installers - De Dietrich . The De Dietrich 7737150P hot water sensor is responsible for measuring and monitoring the temperature of domestic hot water in the system. The temperature sensor is characterized by advanced operating technology, thanks to which it also provides excellent thermal comfort. Precise control of water temperature also allows you to limit heat losses and reduce bills. Sensors of this brand are characterized by exceptional durability and solid workmanship, thanks to which the product can be used for a long period of time. This is an element eagerly chosen by installers because its installation does not cause many difficulties and the number of potential failures is negligible.
The Onninen range also includes Rotenso hot water sensors, such as the Rotenso RASN-MSDHW hot water sensor . This is a model dedicated to work with the Aquami Multi Split heat pump.
