Unwanted temperature changes are both annoying and dangerous. For instance, when a toilet is flushed, cold water enters the tank of the toilet and reduces the pressure in the cold-water pipes. When taking a shower, someone will notice that the water suddenly gets hotter since there is less cold water available to the shower valve. By the same logic, when someone uses the hot water faucet in the house, the shower water will cool off. Plumbing that is blocked, constrained, or put in showers with many or low-flow showerheads aggravates this issue. Particularly at risk are the physically handicapped and the elderly. SCHELL anti-scalding angle valves with thermostats lessen this risk by keeping the water temperature at a safe level despite changes in water supply line pressure.
In recent years, reports of serious scalding injuries with fatal consequences have shocked the nursing sector, healthcare managers as well as plumbers and fitters. A rapid hot water burst can result in severe burns. A person may fall in the shower while they struggle to change the water’s temperature due to a startling thermal shock, whether it be hot or cold. Therefore, in this article, we have highlighted the ultimate solution to this problem.
Safe anti-scalding protection with universal applicability
Anti-scald valves, often referred to as tempering valves and mixing valves, combine hot and cold water before it exits a fixture so that it won’t be hot enough to scald someone.
The SCHELL angle valve thermostat guarantees reliable anti-scalding protection for high-risk application areas such as childcare facilities, nursing homes, public toilets, or hospitals. The new thermostat ensures safe drinking water hygiene by supporting thermal disinfection. Furthermore, it is easy to install even under narrow installation conditions due to its practical design.
This thermostatic valve provides a dependable, simple-to-install, and aesthetically pleasing option for scald protection. The thermostat, which is installed above the angle valve for the hot water pipe with a connection pipe to the cold water line, ensures that the draw-off temperature will remain constant, for instance at 38°C, regardless of pressure variations and even if the cold water supply actually fails completely. To suit your requirements, you can easily alter the desired temperature.
SCHELL angle valve thermostat – The perfect retrofit
SCHELL’s angle valve thermostat is a great option for washbasin or toilet taps without anti-scalding protection. The valve limits the maximum draw-off temperature thermostatically and is also easy to install in places where space is at a premium, such as underneath low washbasins in nursery schools. Moreover, it is available with a rigid or flexible installation set.
Advantages of thermostat feature
1. Water temperature held constant at up to maximum draw-off temperature
2. Safe anti-scalding protection in the event of cold water failure
3. Individual temperature adjustment
4. Maximum temperature can be set to 38°C or 43°C (conforms to DIN EN 806-2)
Thermostatic valve – Safety aspects
1. Tool required for changeover to thermal disinfection (protection against Legionella)
2. The cover cap can only be fitted after resetting to the operating temperature
3. User-friendly: After thermal disinfection, the operating temperature originally set is retained
4. Typical areas of use: Schools, nurseries, hospitals, retirement homes, hotels, etc.
Backflow preventer
1. SCHELL thermostatic valves exhibit a high level of hygiene safety with backflow preventer (type-EB) that prevents cross-flows between PWC and PWH
2. Simple maintenance thanks to a backflow preventer that can be replaced as required (conforms to DIN EN 806-5)
Installation
1. Space-saving installation thanks to practical design (also for connecting sets), making it suitable for children’s wash basins or similar kinds of installations.
2. Simple installation, thanks to the outlet connectors, which are not positioned in line with one another.
3. One sealing point less than the previous model.
4. Also, ideal for retrofitting.
In conclusion, using the SCHELL thermostatic tap angle valves minimizes water temperature variations that could otherwise annoy or hurt unwary building inhabitants.
