Assume a 3 chair practice uses 5L purified water per day (so 5 x 5L bottles per week):
a) Bottled water:
- Generates over 78kg of plastic waste each year
- Requires dental staff to carry and store over 1.3 tons of water each year around the practice
- The financial cost is over £1150 pa (£4.50/bottle)
b) Distiller kettle:
- Only produces 1L of purified water each hour
- Up to 1/18 of each litre of water produced can turn to steam in the decon room, making for an unpleasant working environment for busy dental nurses
- Distiller (750w) can cost over £340* pa in electricity
*making 5L/day, 5 days p/wk, 35p kw/h
c) EauFlow RO:
- Produces 12-20L of purified water each hour (depending on water hardness)
- Is the only RO system to monitor both organic and non organic water impurities
- Is the only RO system with quick-change (and tool-free) cartridges on all 5 stages, thus reducing equipment downtime in busy practices
- Tailors packages to your specific practice’s water needs, thus ensuring cartridge change once pa
- RO costs approx 3p* per day to fill up a 12L tank or £7.80 pa in electricity- over £332 pa (97%) saving pa vs distiller
*making 5L/day, 5 days p/wk, 35p kw/h
Calculations:
Distiller: 5 hours to make 5L= £1.75= £8.75 p/wk= £455 pa x 750w kettle= £341.25.
vs
RO: The electricity consumption per hour of the pump is DC24V x 1.5A = 36w/h = 0.036 Kw/h. 35 pence x 0.036Kw/h = 1.26 pence. So running the EY505 pump for 1 hour (to fill up 12L tank)= 1.26 p. 2x for LED number display.
