Energy Savings Calculator

Initial Investment and Lifetime Return Savings calculations are based on project cost (product + installation costs) of 50-gallon models minus estimated tax credits and rebates. In the final calculations, there can be rounding errors which can account for a small dollar value difference. If the ROI calculation is negative it will state “immediate”. Default water heater prices do not include tax or delivery fees. Rinnai America Corporation is not responsible for tax and rebate filing. Consult with a tax advisor and your local utility company for complete filing and eligibility requirements.

The calculations are based on a 50-gallon Hybrid Electric Water Heater (HPWH) and a 50-gallon standard Electric Tank Water Heater and both having a 9-year warranty. For the Hybrid Electric Water Heater (HPWH), the minimum kWh used in the calculation is 864 kWh. For the Electric Tank Water Heater, the minimum kWh used in the calculation is 3,493 kWh.

For the United States:  The estimated federal tax credit is calculated as 30% of project cost. The minimum kWh used in the Energy Savings calculation is based on the US Department of Energy (DOE) Energy Guide label of like models that are readily available for purchase on the Internet.

For Canada:  The minimum kWh used in the Energy Savings is from a table provided by Energy Hub website. For updated average electricity energy rates in Canada refer to Energy Hub website URL https://www.energyhub.org/electricity-prices.
