The family keeps running out of hot water and wants an endless supply with a tankless unit.
| Tankless water heater install | $3,200 |
| Gas line upgrade | $650 |
| Venting kit | $300 |

What customers ask a water heater tech
Tank or tankless?
Send each option as its own estimate.
Will my gas line work?
Many tankless units need a bigger line — explain.
How long does install take?
Often a day.
Tips for your water heater tech business
- Always check gas and venting before quoting tankless.
- Annual flushing is a repeat service.
- Emergency replacements close fastest when you can schedule the same day.

Questions water heater installers ask
Can customers pay a deposit?
Yes. Set a deposit on the estimate; the customer pays it by card and approves the job at the same time.
Can I track what is in my van?
Yes. Track items in Van stock; they come off automatically when a job is marked done, and Selk warns you when you are low.

Selk costs $29/month for Solo, $79/month for Contractor (owner plus up to 5 workers), and $129/month for Contractor 10 (owner plus up to 10 workers). The first 100 companies lock in founding prices of $19, $49 and $89 per month for as long as they stay subscribed.

No. Workers are always free on every Selk plan. There are no per-seat fees, and the worker app is separate from the contractor app.
