Water Heater Cost Calculator

This app will help you decide which water heater to buy. It allows comparison between your existing water heater and any number of electric or gas, tanked or tankless water heaters. It includes the cost of purchase and installation, the cost of operation, and factors in things like the lifetime of the heater. Using the graph, you can see when you would pay back the difference between two alternative heaters. For more information, read the blog post about this calculator.
