Replacing a Gas Dryer with Electric: The Process

Of the four gas appliances in a typical home, the dryer is usually the easiest to convert — and it's frequently the one standing between you and cancelling gas service entirely.

Should you buy a 120V heat pump dryer or a 240V vented dryer?

This determines whether the project needs an electrician at all.

Heat pump dryer, often 120V. Runs on a standard circuit because the heat pump needs far less power than a resistance element. If a suitable 120V outlet exists in the laundry area, this can be a straight appliance swap — no electrician, no permit for electrical work, no panel capacity question. Longer cycles, no vent required, lower running cost. See heat pump dryers explained.

Conventional electric dryer, 240V. Faster cycles, cheaper to buy, but needs a dedicated 240V circuit that a gas laundry area almost certainly doesn't have. That means an electrician, a permit, and panel capacity.

For an electrification project, the 120V heat pump option is often decisive — see heat pump dryer vs vented dryer for the full comparison and 120V appliances for electrification for where this fits more broadly.

Check the specific model. Not all heat pump dryers are 120V, and requirements vary.

What do you need before replacing a gas dryer?

Look at the laundry area:

• Is there a 240V receptacle? Some homes have one from a previous electric dryer even though a gas dryer is installed now. If so, the 240V path is easy — check the configuration against the new appliance. See the NEMA plug chart.
• Is there a 120V outlet, and what else is on that circuit? A gas dryer already uses one for its controls and drum motor, but a heat pump dryer draws considerably more — it should not share with other significant loads.
• Where's the gas shutoff, and is it accessible?
• Where does the vent run, and is it in good condition?

What circuit does an electric dryer need?

If going 120V heat pump: confirm the outlet is on a circuit that can support the appliance. Check the model's requirement — some specify a dedicated circuit. If the laundry outlet is shared with other loads, an electrician can run a dedicated one, which is a much smaller job than a 240V circuit.

If going 240V: you need a dedicated 240V circuit sized to the appliance's nameplate. Run a load calculation for your full electrification plan first — the home electrical load calculator. See dryer electrical requirements.

If capacity is tight, this is exactly the situation where a 120V heat pump dryer solves the problem outright. Otherwise see electrifying without a panel upgrade.

Who caps the gas line for a dryer?

Licensed work. A plumber or gas fitter shuts off the supply, disconnects the appliance connector, and installs a proper cap on the piping. Normally permitted and inspected.

Two points:

• A cap, not just a closed valve. A shutoff valve is a control device, not a permanent termination.
• Consider removing the branch back to the tee if nothing will use it again — cleaner than a capped stub in the wall, and it avoids questions at future inspections.

See capping an unused gas line. Don't do this yourself.

Step 4: Deal with the vent

If you chose a vented electric dryer: reuse the existing vent. Check its condition while the old dryer is out — this is the one moment the duct is accessible. Clean it, confirm it terminates outside (not into the attic or crawlspace), and check the exterior damper works.

If you chose a heat pump dryer: the vent becomes unused. Cap and seal it. An open duct is an air leakage path through the envelope and a pest entry point. This takes minutes and is easy to forget.

Step 5: Install and set up

Standard laundry appliance installation: level the machine, connect power, and for a heat pump dryer decide how to handle condensate.

Plumb the condensate to a drain if possible. Most heat pump dryers can either drain to a standpipe or collect water in a reservoir you empty each cycle. If the laundry area has a drain — and it usually does, for the washer — plumbing to it is worth the small extra effort. Emptying a reservoir every load gets tedious quickly.

Can you drop gas service after the dryer?

This is the step that makes the whole project worthwhile.

If the dryer was your last gas appliance, you can now:

1. Have any remaining gas piping capped or removed
2. Contact the utility to remove the meter and close the account
3. Stop paying the fixed monthly service charge permanently

That fixed charge is billed regardless of usage, so eliminating it is a permanent saving unrelated to how much energy the dryer used. For many households it's larger than the dryer's own energy cost — which is the real financial argument for converting a dryer at all.

See removing your gas meter, how to decommission a gas line, and electrification and your electric bill.

If other gas appliances remain, note this on your plan — the dryer conversion pays off fully only once the last one goes.

Adjusting to a heat pump dryer

If that's what you chose:

• Cycles run longer. Start loads earlier.
• Clean the condenser filter on the manufacturer's schedule — the most-skipped maintenance item, and skipping it makes clothes come out damp
• Clothes come out cooler, which is normal
• The unit rejects some heat into the room

Realistic effort

The first row is why the dryer is often recommended as an early, confidence-building electrification step.

The bottom line

Decide 120V heat pump versus 240V vented first, because it determines whether you need an electrician at all — a 120V heat pump dryer into an existing suitable outlet is close to a plug-and-play conversion. Have a licensed professional cap the gas line, seal the unused vent, plumb the condensate to a drain if you can, and then check whether this was the last gas appliance. If it was, dropping the meter is worth more than the dryer.
