Worked example: one Connecticut home
Take one heat pump water heater replacing an electric tank. These are example inputs, not typical prices. Each program's own rule gives the amounts below; where one program has several tiers only the largest one counts, separate programs add up, and a percentage offer with no cost entered is shown at its ceiling.
| Utility | Not income-qualified | Moderate income | Low income |
|---|---|---|---|
| Eversource (Connecticut) | $900 | $1,900 | $1,900 |
| United Illuminating (UI) | $900 | $1,900 | $1,900 |
For a household that is not income-qualified, the example comes to $900, made of $900 from Energize CT water heaters (Standard). A household that meets a program's low-income definition gets $1,000 more in the same example, because 1 offer is paid at the income-qualified level. All 2 listed utilities come out the same, because the money comes from a shared program.
