More San Jacinto homeowners are making the switch to tankless water heaters — and once they do, most say they wish they’d done it sooner. But is a tankless water heater right for your home and budget? Davis Plumbing and Heating Inc. installs tankless systems throughout San Jacinto and Riverside County, and we’ll give you an honest answer.
How Tankless Water Heaters Work
Unlike traditional tank units that constantly heat and store 40–50 gallons of water, a tankless (or “on-demand”) water heater heats water only when you need it. Cold water flows through a heat exchanger — powered by gas or electricity — and delivers hot water instantly at the tap. Because you’re not heating a standing tank of water 24/7, you eliminate standby heat loss, which accounts for 15–30% of a conventional water heater’s energy consumption.
Advantages of Going Tankless in San Jacinto
- Endless hot water: No more running out mid-shower or rationing hot water for back-to-back showers
- Energy savings: Tankless units use 24–34% less energy than comparable tank units — significant in San Jacinto’s year-round warm climate where water heating is a major energy cost
- Longer lifespan: Properly maintained tankless units last 20+ years vs. 10–12 for tanks
- Space savings: Wall-mounted units free up utility room floor space
- No flood risk: Without a tank, there’s no tank to rupture or leak 40–50 gallons onto your floor
- Tax credits: Energy-efficient tankless water heaters may qualify for federal tax credits under the Inflation Reduction Act
Things to Know Before Going Tankless in San Jacinto
Tankless isn’t perfect for every situation. Here’s what to consider before making the switch:
- Higher upfront cost: Tankless units cost more to purchase and install than traditional tanks. Budget $1,800–$3,500+ for a complete installed system.
- Gas line upgrade may be needed: Most gas tankless units require a ¾” gas line. Many older San Jacinto homes have ½” lines that need upgrading.
- Hard water requires maintenance: San Jacinto’s mineral-rich water causes scale buildup inside tankless heat exchangers. Annual descaling is important to maintain efficiency and prevent premature failure.
- Flow rate matching: You need to make sure your chosen unit’s GPM (gallons per minute) rating matches your household’s peak demand.
