Endless hot water, up to 40% lower energy bills, and a 20+ year lifespan. Izzy Plumbing Inc. installs, services, and repairs all major tankless brands across San Luis Obispo County. Residential diagnostic fee $89 · Business/Commercial $150 · 12-month workmanship guarantee.
Homeowners across San Luis Obispo County are switching to tankless for the immediate comfort gains and long-term savings. Here's exactly what you gain.
Tankless water heaters heat water on demand — no storage tank to run out. Enjoy unlimited hot showers, back-to-back laundry, and full dishwasher runs simultaneously without ever going cold.
Traditional tank heaters reheat 40–80 gallons of water 24/7 even when you're not using it. Tankless units fire only on demand, cutting standby energy losses and slashing your utility bill by up to 40%.
A conventional tank lasts 8–12 years. Tankless units last 20 years or more with proper maintenance — doubling your return on investment and reducing landfill waste.
Tankless units are wall-mounted and roughly the size of a carry-on suitcase. Reclaim your utility closet, basement, or garage space — a huge win in San Luis Obispo's smaller homes.
Lower energy consumption means a smaller carbon footprint. Many tankless units qualify for California rebate programs, further reducing your upfront costs while doing right by the environment.
Modern tankless systems heat water to your set temperature in seconds. Pair with a recirculation pump for near-instant delivery at every faucet throughout your SLO home.

"Izzy Plumbing installed our Navien tankless unit in one day. The technician explained everything clearly, pulled the permit, and even handled the SoCal Gas rebate paperwork for us. Hot water is instant now — we'll never go back to a tank!"

"Had an older Rinnai tankless that kept throwing error codes. Called Izzy Plumbing and they diagnosed the igniter issue within 20 minutes. Fixed it same day for a very fair price. The $89 diagnostic fee was totally worth it."
James K.

"We were skeptical about the upfront cost, but Izzy Plumbing showed us the exact ROI calculation — our unit pays for itself in 7 years. Two years in and our gas bill is noticeably lower. Highly recommend."
