Tankless Water Heaters in Fontana

Tankless Water Heater Installation, Repair, & Maintenance Across the Inland Empire

Most homeowners switch to a tankless water heater for one main reason: it never runs out of hot water. However, the most important functional difference is that a tankless unit does not have a storage tank to hide severe mineral buildup. Instead, water rapidly passes through a narrow heat exchanger on its way to your tap. In a valley that draws hard groundwater, the condition of that precise passage dictates the entire working life of your unit. 

Family Ties Air, Plumbing, & Drain provides installation, repair, and maintenance services for tankless systems throughout Fontana. Upgrading to a tankless system requires specialized gas and venting work, and our in-house plumbers handle every phase of the conversion directly rather than subcontracting it out. Because we also service conventional tank heaters, we will help you objectively weigh both options against your household's true hot water demands before recommending a switch. 

Our team is ready to provide help in either English or Spanish. To schedule an estimate for tankless water heater services in Fontana, call (909) 328-1409 or contact us online

What a Tankless Installation Involves

Mounting a sleek new tankless unit to your wall is actually the most straightforward part of the entire installation process. The real work happens behind the scenes. Because a tankless system heats water instantaneously on demand, its burner fires at a significantly higher input than a traditional storage tank. To support this massive, sudden energy draw, the existing gas line serving many older homes must be upsized to safely supply the required fuel volume. 

Venting requirements also undergo significant changes during a conversion. A modern, sealed combustion tankless unit operates differently than older models and cannot safely share the same flue that an atmospheric tank previously used to vent exhaust. Dedicated venting must be carefully routed to the outside to safely manage the exhaust and condensation produced by these high-efficiency units. 

Furthermore, replacement work within the city limits requires strict municipal permitting and a thorough safety inspection. Dealing with local building codes can be a headache, so we take that burden completely off your shoulders. We pull all the necessary permits and schedule the city inspections as a standard part of the job so you know the work is perfectly up to code. 

The immediate payoff for this extensive labor is a highly efficient, wall-mounted unit that completely reclaims the floor space your bulky old tank used to occupy. In the narrow garage utility corners common in local tract construction, getting that square footage back is a massive advantage. You suddenly gain room for extra storage, a cleaner workspace, and a much less cluttered garage. 

Tankless Water Heater Solutions for the Inland Empire

Unlike traditional water heaters, these modern units rely on sensitive electronic components, high-capacity gas valves, and precise water-flow sensors to deliver continuous hot water. When a component needs attention, you need a team that truly understands the exact mechanics inside the cabinet. We deliver exactly that level of technical skill.

Our comprehensive tankless water heater solutions across the city include: 

  • Installation and replacement. Sizing the unit to your household's peak simultaneous demand rather than simply matching the capacity of the unit it replaces. 
  • Gas line and venting upgrades. Bringing your fuel supply and exhaust systems up to the strict standards a high-input burner requires. 
  • Descaling and system flushing. Clearing out the damaging mineral deposits that hard water leaves along the inner walls of the heat exchanger. 
  • Error code diagnosis. Accurately reading and interpreting what the unit is reporting before any parts get replaced on a blind assumption. 
  • Recirculation pumps and dedicated return lines. Shortening the wait time for hot water at fixtures located far away from the main unit. 

Manufacturers generally require documented annual service to keep their warranties active, meaning a skipped flush can easily cost you far more than the maintenance visit would have. 

We also back every installation we complete with our own solid warranty.
