Short answer
Water heaters sit on the boundary between the plumbing and heating trades, which is why this comparison is unusual: the right company depends on what actually makes your hot water. A standalone electric or gas tank is plumbing work. An indirect tank fed by a boiler, or a switch between fuels, pulls in heating expertise, venting and combustion, and a business strong on one is not automatically competent at the other. Compare whether the business handles your exact equipment type instead of just tanks generally, recovery rate against your actual peak demand, not tank volume alone, the venting and electrical work a change of type would require, and whether the replacement route physically fits your stairs and mechanical space.

When this is the wrong comparison
A failing tank or a water-heater replacement is its own comparison. Leaks, drains, fixtures, repiping and general plumbing service are compared separately, and the company you want for a failing tank is not necessarily the one you want for a recurring drain problem. Use the other guide for that.
What a written estimate should show
Put these 6 points to every business and write the answers next to each estimate.
- Whether the company handles your equipment type, not just tanks generally
- Recovery rate against your actual peak, not tank volume alone
- Venting, combustion air and electrical work a change of type would require
- Whether the replacement route physically fits the stairs and the space
- Removal, permits, expansion tank and drain work, itemised
- Warranty registration, and whether an authorised servicer is required
Reading the estimate line by line
The table sets a strong answer beside a weak one for the lines that most often decide the total.
| Estimate line | A strong estimate says | A weak estimate says |
|---|---|---|
| Unit type | Tank, tankless, indirect or heat-pump, with reasons | "A 50-gallon heater" |
| Recovery | Sized to your peak demand, not tank volume | Volume only |
| Fuel and venting | Says what changes if the fuel or vent changes | Silent |
| Included work | Removal, permit, expansion tank and drain itemised | One lump price |
| Warranty | Says who services it and whether registration is needed | "Manufacturer warranty" |
Vermont licences and permits for this work
A water heater sits on the line between plumbing and heating. A licensed plumber handles the water piping, valves and expansion tank. A fuel-fired unit also brings in a Certificate of Fitness holder from the Division of Fire Safety for the gas or oil connection and the venting. An electric or heat-pump unit needs a licensed electrician for the circuit.
The estimate should say who does each of those, especially when you are changing fuel or type. A company that is strong on tanks is not automatically the right one for a tankless or heat-pump unit.
What changes the job around Burlington
Heat-pump water heaters have a discount worth asking about: Efficiency Vermont lists a $600 discount, up to $1,000 total, the extra $400 for income-eligible households. Your electric utility may pay part of it, so the estimate should say who applies and which utility programme it assumes.
Vermont houses that heat with oil or propane often pair the water heater with the boiler as an indirect tank, which changes what can go wrong and who should fix it. In many Burlington-area basements the real constraint is stairs and headroom, so the estimate should confirm the new unit can be carried in and the old one carried out.
Warning signs in a written estimate
- A unit chosen without asking how many people use hot water at once
- No mention of venting or combustion air on a fuel-fired unit
- Removal and disposal left out
- An electric unit proposed with no check of the panel
- A warranty that needs registration nobody offers to do
Questions to ask before you sign
- What is the recovery rate compared with how we actually use hot water?
- Does a change of fuel or type need new venting, gas work or a new circuit?
- Will the new unit physically fit down our stairs?
- Are the permit, expansion tank and disposal in the price?
- Who registers the warranty and who services the unit?
