Chalmor Saving Energy on Inefficient Tea Boiler Water Heaters
Often found in school staff rooms and workplace kitchens 'tea boilers' or storage water heaters are wall-mounted containers providing hot water on demand. They are extremely convenient, but can consume a lot of energy if they are left on continuously.
The Chalmor MoveMaster retrofits directly to tea boilers. It combines a timer to automate water heating with an occupancy sensor to switch the heating on or off on a needs basis. This dramatically reduces energy consumption.
The following data was obtained from a monitoring exercise in a public sector office building, which summarises kWh consumption per week:
- A typical week consumed 25.5 kWh
- Using the MoveMaster reduces consumption to 14.5 kWh, a saving of 11 kWh per week, or 43%
- This will reduce electricity bills by upwards of £70 per boiler per annum, providing return on investment within a year and the potential for huge savings across a large estate.
