A lower number is not a better quote until both quotes describe the same job. Two quotes can differ because they name different units, different venting, a different amount of supply work, or leave different items out. The U.S. Department of Energy advises requesting cost estimates in writing, and the worksheet below turns that advice into lines you can compare. It builds on our guides to choosing a contractor and settling repair or replace, and it carries no local price.
First, Make It The Same Job
Give every installer the same description of the existing unit and the same list of questions. That means the fuel, the venting and the location of the current heater, the model number from its rating plate, and what you want, including whether you are changing type or fuel. If a quote cannot be matched line by line, ask the installer to restate it in the same order as the others; if an installer will not itemize, note that.
The Worksheet
Each row is something a written quote can state, with the source that says why it matters. Copy the table, fill in each quote, and look for rows that are blank on one side.
| Line | What the quote should state | Why it matters | Quote A | Quote B |
|---|---|---|---|---|
| Unit | Manufacturer, model, fuel and capacity | Two quotes for different models are different jobs; model documents set the conditions that apply | ||
| Delivery rating | First-hour rating of the specific model | The DOE says to size a storage or heat pump tank by first-hour rating; see our sizing guide | ||
| Efficiency rating | The model’s published efficiency rating | ENERGY STAR certifies non-solar water heaters by Uniform Energy Factor criteria | ||
| Venting | Venting type by name, route and termination | Atmospheric, power vent, direct vent and power direct vent differ in what they need; see our venting guide | ||
| Fuel or electrical changes | Gas line, regulator, breaker or circuit work, if any | The DOE says a fuel conversion has other cost considerations, such as adding a breaker or running a gas line | ||
| Thermal expansion | Whether the supply is closed and what is provided for expansion | A. O. Smith says the relief valve is not to be depended on for thermal expansion; see our expansion tank guide | ||
| Relief valve discharge | Relief valve and discharge pipe, routed and terminated per the manual | State Water Heaters’ manual says the discharge must exit within 6 inches above or below the floor and must not be plugged | ||
| Permit | Who obtains it, and which authority applies | This page states no permit requirement for any address; the DOE advises asking whether the company will obtain a local permit | ||
| Old unit | Removal and disposal, included or not | An unstated item may appear as an extra later; ask for it in writing |

Scope And Exclusions
Exclusions are where equal-looking quotes diverge. Ask each installer to list what the price does not include, in the same categories: permit fees, disposal, code-driven venting or gas line changes, electrical work, an expansion provision, and any work discovered after the old unit is out. The DOE’s guidance on choosing a contractor adds asking for references and checking the company with your local Better Business Bureau. We state no price for any line, because the national planning ranges we hold are national, not Lancaster quotes; the repair cost guide gives them with their labels.
Credentials And Documents
Registration, license and insurance are separate things, and the quote should let you check each. Registration under the Pennsylvania Home Improvement Consumer Protection Act is not a license, according to the Pennsylvania Attorney General’s FAQ. That statement is repeated as recorded in our registry on August 27, 2026; we could not reopen the Attorney General’s pages when preparing this page, so we state no requirement about what a Pennsylvania quote or contract must contain. Ask where the registration number appears and check it directly with that office. For the warranty, ask for the document for the exact model; our manufacturer documents guide shows how two Rheem documents differ. We compare no coverage lengths.
Gaps To Resolve Before You Sign
- No model number. Ask for it; without it you cannot check the first-hour rating or the documents.
- No venting type named on a gas quote.
- No mention of thermal expansion when the supply may be closed.
- An unstated permit. Ask who pulls it and what the authority having jurisdiction asks for.
- A single total with no lines. Ask for it itemized in the order of the worksheet.

What This Page Will Not Say
It will not say what a quote should cost, which installer to pick, or what permit a particular address needs. We hold no Lancaster price for any line, no municipal permit fee figure, and no authoritative rule for what a contract must contain that we could open this session. The worksheet is a way to make quotes comparable, not a verdict on any of them.

What should be on a water heater installation quote?
The unit, the venting, any fuel or electrical changes, the permit, disposal and the exclusions, each stated in writing. The U.S. Department of Energy advises requesting cost estimates in writing. The worksheet above lists each line with the document that says why it matters.
Why are two quotes for the same water heater so different?
Because the quotes may not describe the same job. They may name different models, different venting, different supply work, or leave out items such as the permit or disposal. Restate both in the same order before comparing totals.
Should I just pick the lowest quote?
Only once both quotes describe the same job. A lower figure can mean a different unit or a longer exclusions list. We do not say which price is right, and give no local price for any line.
Who pulls the permit for a water heater replacement?
Ask each installer, and ask which authority applies. This page states no permit requirement for any address, and the U.S. Department of Energy advises asking whether the company will obtain a local permit if necessary. We hold no municipal rule for most Lancaster-area municipalities.
Is a Home Improvement registration number the same as a license?
No, according to the Pennsylvania Attorney General’s FAQ. Registration is not a license and does not require an exam or proof of trade skills. We could not open that page this session, so verify the statement and the registration lookup directly.
