How Do Heated Hand Wash Units Work, and What Are Their Benefits?
How Do These Units Work?
Unlike instantaneous water heaters, which heat water as it flows through the system, heated hand wash units store water inside an insulated tank.
An internal heating element warms the water to a set temperature, while a thermostat maintains that temperature by switching the heating element on and off as required.
This means warm water is ready whenever it's needed.
What Are the Main Benefits?
Reliable Warm Water
Jobec's latest heated hand wash units have a 15-litre capacity, providing a convenient supply of warm water for temporary washing facilities.
Better Protection Against Freezing
Unlike conventional instantaneous heaters, insulated storage tanks retain heat for longer, helping reduce the risk of freezing during colder weather.
However, protection against freezing still depends on the surrounding temperature and whether electrical power is maintained.
Good Heat Insulation
Effective insulation reduces heat loss, keeping water warmer for longer and reducing how frequently the heating element needs to operate.
Low-Water Safety Protection
Running a heating element without sufficient water can cause damage.
Jobec's units feature an audible low-water alarm and an automatic heating cut-off, helping protect the equipment when water levels become too low.
Why Use MDPE Plastic?
Jobec's heated hand wash tanks are rotationally moulded using pure virgin medium-density polyethylene (MDPE).
This material offers excellent impact resistance, durability and resistance to corrosion, making it suitable for demanding environments such as construction sites and portable welfare facilities.
Where Can Heated Hand Wash Units Be Used?
Heated hand wash units are suitable for various temporary and outdoor applications, including:
-
Construction sites
-
Portable toilets and welfare units
-
Outdoor events and festivals
-
Agricultural facilities
-
Temporary workspaces
Jobec manufactures both 110V and 230V versions to accommodate different electrical supply requirements.
Heated Storage Units vs Instantaneous Water Heaters
Instantaneous heaters warm water as it flows through the system, whereas heated storage units maintain a ready supply of warm water.
Storage units are particularly useful for intermittent hand washing, although they have a limited capacity and require time to reheat after heavy use.
Final Thoughts
Heated hand wash units provide a straightforward and practical way of supplying warm water where permanent facilities aren't available.
With good insulation, temperature control and built-in safety features, they're a useful option for construction sites, portable toilets and other temporary facilities.
