Case Study Results
Date of installation – APRIL 2016
Since the installation in April, electricity consumption has been monitored on both the Ecocent cylinders & the commercial dishwasher. The results are extremely positive and have already showed the Ecocent units are performing exactly as planned.
Electricity consumed by the dishwasher has been reduced by 108.4kWh per day. 108.4kWh x £0.10 = £10.84 saving per day / £3,804.84 per annum.
The Ecocent units produce the equivalent of 3kW of air cooling per hour. This has been factored into the energy savings as it is a Bi-product. The 2 Ecocent units therefore produce 6kW of cooling per hour over an average of an 8 hour cycle per day. 6kWh x 10hours =60, 60 x £0.10 per Kwh = £6.00 per day, £2,106.00 per annum.
Operational costs of the Ecocent units have been metered since the installation. The units operate by consuming 680watts of power per hour. There is a 1.5kw immersion back up inside the cylinder to offer 100% protection from legionella. This can raise the electrical consumption slightly during times of the day where the demand for hot water is at its peak.
The daily electrical consumption shown on the Meters have shown an average daily consumption of 9Kwh per Ecocent cylinder. 9Kwh = £0.90 per unit per day = £0.90 x 2 Ecocent’s = £1.80 per day x 351 days = £631.80 per annum.
Breakdown of Savings
Electrical savings from dishwasher: £3,804.84
Electrical savings from cooling: £2,106
Operational costs of the units: £631.80
Total savings (energy costs) £5,279.04
Total carbon savings the carbon savings from the ecocent installations are equal to the carbon emissions of 2 UK homes per annum (UK average)
