Degasser, Sludge separator and pH regulation in one unit:
For the long-term regulation of the heating water and the reliable prevention of new deposits, the installation of a magnetic heating water regulator is recommended. This not only saves energy, but also reduces the risk of damage caused by corrosion products in control valves and pumps. Especially in heating systems that are open to diffusion and thus have an increased risk of corrosion, the HWR (heating water regulator) eliminates all causes of corrosion and sludge formation.
HWR plus is a unit designed as a result of many years of research and experience. Once correctly installed by qualified engineers/plumbers, it provides maximum security for the value retention of your entire heating system – whether old or new.
Unfavourable water values can occur in any heating system, traditionally leading to corrosion and subsequent system damage. The causes of this corrosion have been identified as oxygen, an acidic pH or an increased electrical conductivity. The pH value drops especially under sludge deposits and the heating water becomes acidic. The heat transfer efficiency is reduced and valuable energy is lost.
Solution step # 1 – degassing:
Reliably removes oxygen and gases from the heating circuit. Underfloor heating pipes, valves, pumps, screw connections, breather or defective expansion vessels can be causes of increased oxygen in the heating system. This is one of the main causes of increased risk of corrosion. The heating water regulator HWR plus continuously removes gases that are dissolved in the heating water. Gases bind in the cooler heating water and are released again when heated. In a heating system, the water in the radiators and heating circuits cools down. It “breathes” in gases and releases them after heating in the boiler. These newly freed micro gas bubbles are transported through the circulation system, separated and combined in the HWR via a sophisticated filter system. The now large bubbles have enough buoyancy to rise in a quiet zone in the HWR, from where they are then removed from the system with an automatic device. The now degassed heating water is able to dissolve new gases in order to feed them to the HWR. This means that even air deposits from the highest points in the heating system can be detached and separated, continuously, efficiently and without external energy.
Solution No. 2 – anode protection.
The HWR anode stabilizes the pH value, lowers conductivity and minimizes oxygen entry. The reaction tank of the heating water regulator HWR is equipped with a specially developed sacrificial anode. The oxygen is forced to connect to the sacrificial anode by a galvanic current. This creates magnesium hydroxide – this brings the pH value into an optimal range. As a positive side effect, the salt content is reduced, which results in lower electrical conductivity. The HWR thus produces low-salt, alkaline water with a minimal oxygen concentration. When the sacrificial anode is used up, normally after 2-6 years, depending on water quality, it can be quickly replaced in a few simple steps. The reaction container is made of rustproof material and therefore free of wear. There is a visual indicator present to alert when anode needs to be replaced.
Solution step no.3 – combination filter
When the sludge is taken out of the heating circuit – the water becomes clear again The sludge must be filtered out of the heating system so that deposits no longer clog heating circuits / control elements and promote pitting. In the heating water regulator, the principle of gravity filtration is perfectly combined with a magnetic flux filter. This combination is what makes this system so unique. This means that even the smallest sludge particles are reliably disposed of. The magnet is attached on the outside, thus enabling the blowdown to be carried out without interrupting the heating operation. By pulling back the magnet, the corrosion particles are released and can be easily removed using the drain valve.
HWR compact plus, suitable for domestic and smaller systems. The magnetic HWR compact plus is the compact solution for all systems, up to a water content of 500 l. What is particularly convincing is the compact design and the excellent price-performance ratio. A powerful protective anode for raising the pH value, degassing and a combined magnetic flux and sludge filter are integrated in the device. This increases the effectiveness of the corrosion protection and reduces the complexity during installation and operation.
The magnetic heating water regulator plus has a replaceable high-potential protection anode made of a special magnesium-manganese alloy. The anode should be checked and replaced, when alerted by visual indicator on HWR plus. The shelf life of the anode is between 2 and 6 years, depending on water quality. For the exchange, you will receive suitable interchangeable anodes for magnetic heating water regulating devices.
