Electric Hot Water Tank Cost: Unit Price vs Installed Price
What an electric hot water tank really costs once labour, a new circuit, permits and old-tank disposal are added to the sticker price.
An electric hot water tank typically costs about $1,950 installed in Canada, before GST/HST. Our overall range for a replacement is $1,950 – $3,200, and the tank itself is only part of that.
The number on the shelf is not the number on your invoice. Here is what sits between the two, and how to tell which version of the job you are facing.
What the tank price leaves out
A store or online listing shows the unit only. An installed quote adds several things:
- The tank. Size, warranty length and element design drive the price. A longer warranty usually means a thicker anode and better insulation.
- Labour. Draining the old tank, moving the new one into place, connecting water lines and relief valve, filling, and testing. We build this from labour hours × local rates, then check it against market prices and real quotes.
- Fittings and consumables. Flexible connectors, a new temperature and pressure relief valve, a drain pan and discharge pipe, and a shut-off valve if yours is seized.
- Old-tank removal. Many installers include haul-away, but some list it separately. Ask.
- Electrical work. Often zero for a like-for-like swap, and a real cost if the circuit needs changing (see below).
- Permits. Electrical, gas and plumbing work needs licensed trades and usually a permit. In Ontario, a licensed electrical contractor files electrical permits and notifications with the Electrical Safety Authority (ESA).
- GST/HST. Our figures exclude it. HST in Ontario is 13% and GST in Alberta is 5%, so add it when you compare against a quote.
Three situations, three different bills
The biggest swing in cost is what the new tank connects to. We model three cases:
- Like-for-like swap. An electric tank replaces an electric tank. The circuit, breaker and wiring are already there, so you pay for the unit and a straightforward install.
- New electrical circuit. This applies if the old circuit is undersized, damaged or shared, or if you are moving from another fuel to electric. A licensed electrician runs a dedicated circuit and fits a breaker, and the permit comes with it. If your panel is full, the job grows further; our [house rewiring guide](House rewiring) covers the panel side.
- Switching from gas. Going electric removes the gas line and venting from the picture, but you need the circuit in case 2. Going the other way, to gas, adds a new gas line and venting. Gas and electrical work both need licensed trades.
You can see how each changeover is priced in our cost guide: Water heater replacement.
Electric tank vs the alternatives
If you are choosing between technologies rather than just sizes, the installed price differs more than the unit price suggests.
| Material | Typical | Usual range | Lifespan |
|---|---|---|---|
| Electric tank, 40-50 gal | $1,950 | $1,500 – $2,500 | 10-15 years |
| Gas tank, 40-50 gal | $2,500 | $1,950 – $3,200 | 8-12 years |
| Tankless gas (condensing) | $4,750 | $3,700 – $6,200 | 15-20 years |
| Heat pump (hybrid) water heater, 50 gal | $5,750 | $4,500 – $7,500 | 12-15 years |
A few reading notes:
- Electric tanks are usually the cheapest to buy and install, but they are not always the cheapest to run.
- A heat pump (hybrid) water heater costs more upfront and uses less electricity. It also needs space and air around it, so it suits a basement better than a closet.
- A tankless gas unit only makes sense where gas already runs to the house.
For a typical electric tank we show $1,950. A heat pump unit comes in at $5,750, which is the number to weigh against lower running costs over the life of the unit.
Where the extra cost hides
Quotes that look similar can differ by hundreds of dollars. Check these before you sign:
- Access. A tank in a tight utility room or up a flight of stairs takes longer to swap.
- Condition of the old plumbing. Corroded shut-off valves or unions turn a one-visit job into a longer one.
- Drain and floor. A pan and drain line are good practice and add a little to the materials.
- Size. Moving to a larger tank can mean a different breaker and wire gauge. Ask whether the existing circuit is rated for the new element load.
- Emergency timing. A tank that has already failed leaves you little room to compare quotes. Planning a replacement as soon as the old one shows age (rust at the fittings, damp at the base, or a long service life) gives you time.
How to check a quote
Ask for a line-by-line breakdown: unit, labour, electrical work, permit, disposal, taxes. Then compare it with the live figures on this page. If a quote is well above our range, the likely reasons are a new circuit, a hard-to-reach tank or a premium model. If it is well below, check that disposal, permit and a relief valve are included.
You can also run it through our "is my quote fair" tool, which compares your quote against the cost model for your region.

The short version
Budget for the installed price, not the unit price. A like-for-like electric swap sits at the low end, a new circuit or panel work pushes you up, and a heat pump unit costs more now to save on the power bill later. Get two or three itemised quotes from licensed trades and check that permits are included.
