Tankless Water Heaters

Tankless (on-demand) water heaters heat water only when you need it, which means no standby energy loss, no bulky tank taking up garage space, and no running out of hot water halfway through a shower. It is the upgrade we get asked about most — and the one we install most often.

Going tankless is not a simple swap: gas supply lines frequently need upsizing, venting must be replaced, and the unit has to be sized for your fixtures and our cold-water inlet temperatures. JJB Plumbing handles the complete conversion — gas, venting, condensate, water connections, and isolation valves for future service — and we service and descale existing tankless units too.

What we handle

• Tank-to-tankless conversions, fully permitted
• Gas line upsizing and new venting runs
• All major brands, including Rinnai, Noritz, and Navien
• Correct sizing for your home's fixture count and usage
• Annual descaling and flush service — critical with our hard water
• Isolation valve installation for easy maintenance

As a licensed contractor that has installed tankless systems across Placer and Sacramento counties for 30+ years, we will give you an honest assessment of whether tankless pencils out for your home — and a free estimate either way.
