- Assessment rule: Electrical supplyElectric tankless heaters need a large electrical supply, often 120 A or more on their own. Any panel or wiring upgrade is priced after a visit.
- Assessment rule: First water heaterNew water lines, venting, and a gas line or electrical circuit for a first water heater are priced after a visit.
- Assessment rule: New locationMoving the water heater to a new spot is priced after a visit, because it depends on the pipe and vent routes.
How the price is worked out
Each fuel and number of bathrooms has an installed price per package. In the sample, a gas heater for a home with 2 bathrooms is $3,600 (Standard) or $4,700 (Premium). Replacing a tank adds $650 for new venting. Removing the old water heater adds $200 to Standard; Premium already includes it, so it shows as “Included”. That gives $4,450 and $5,350 before tax.
When the gas pipe is only 1/2 inch, a larger gas line adds $750; if the customer doesn't know, the estimate shows a range from no gas line work up to the upgrade. An attic or crawl space install, a scale protection filter and a recirculation pump (part of Premium) are added when they apply. Electric heaters for four or more bathrooms are ruled out with a plain reason. Electrical supply upgrades, a first water heater and a new location are priced after a visit, while the heater itself is still priced.
What you can change
- Installed prices by fuel and number of bathrooms, for each package.
- Venting, gas line, removal and attic prices.
- Extras, and which packages include them.
- What “I don't know” does, and which situations are priced after a visit.
What still needs your visit
The gas load, the venting route and the electrical capacity. The estimate shows its assumptions and says the price is preliminary.
