Tankless Water Heater — Pros and Cons

Tankless units deliver hot water on demand, take up almost no space, and cost more upfront. Whether that math works depends on your house.

Common causes

• High household hot water demand
• Multiple simultaneous fixtures
• Space constraints in the utility area
• Preference for endless hot water

Step-by-step

1. 01Confirm gas line size and pressure — tankless usually needs 3/4" gas
2. 02Verify existing venting can accommodate tankless (usually can't)
3. 03Size by flow rate (GPM) not tank volume
4. 04Budget for annual descaling in hard-water areas
