Here is an example of a hot water system installation in Rotorua that we have been monitoring for a while now. There are 5 adults in this home which is in a cool, shady and damp lakeside spot near Rotorua. Because the house is so shady, they have the fire on for a lot of year to keep the house warm enough. They installed a Reclaim CO2 hot water system just after lockdown last year and here are some graphs showing the efficiency of the system and the minimal outlay in energy costs.
The running costs for this example are as low as $0.97 a day, most households spend at least three times that on hot water.
The price of electricity in this example is 25c/kWh and the data really talks for itself!
