“I had an Atlantic Odysseo 2 heat pump hot water system installed in the workshop area of the house where the existing 240-liter hot water cylinder was situated. The heat pump exhaust outlet was vented outside, but the area was of an adequate size and it was not necessary. When it was installed I had an Efergy KW usage meter attached only to the Atlantic Odysseo 2 so I could monitor the KWH used. It operates quietly with little noise and has been operating for a period of nine weeks set on 60 Celsius.
The household consists of 3 adults. The KWH usage per week is listed below, but the first week only includes 4 days. The electric backup element was used on the first day to get the water up to temperature.
My old hot water service I estimated it was using between 10 KWH and 11 KWH per day, where this is ONLY using only 2.72 KWH per day. I would recommend installing an Atlantic Odysseo 2 Heat Pump hot water system, as the power savings will be at least 75%.
