Some other savings to consider
It will save you a whopping 70% on your water heating bills! This can equate to about $700 a year for the average family home. Extend that out for the expected life of the Aquafire (about 15 years) and that’s over $10,000! According to HEEP (Housing Efficiency End-use Project) every 1% improvement in the efficiency of energy use in NZ would result in a benefit of $15,000,000 and reduce CO2 by 1%.
