Before You Buy: CAMPLUX Tankless Water Heater Checklist

The first thing to check is your home’s gas line capacity and venting requirements, as tankless units often require professional upgrades to handle the specific BTU demands.

• ☐ Confirm your gas supply can support a unit with a UEF > 81 — Check with a licensed contractor for your specific gas line size.
• ☐ Verify your plumbing system’s PSI — Ensure your home’s water pressure matches the requirements for a pure copper water tank system.
• ☐ Measure your available space — This unit is designed to save over 50% of available space compared to standard tanks.
• ☐ Budget for professional installation — Account for the fact that a qualified installer is required to manage the gas line and venting.
• ☐ Identify your water points — Confirm you only need to service 2-3 points simultaneously, such as a bathroom, laundry room, and kitchen.

You should not buy this product if your home requires a flow rate higher than 5.28 GPM or if you need to support more than three water points at once.
