Tankless Water Heater Installation & Retrofits in Burlingame, CA
Endless On-Demand Hot Water and Advanced Household Efficiency
Traditional storage tanks continuously reheat standing water, wasting energy and running out of hot water during back-to-back household showers. Power Plumbers and Drains specializes in turnkey tankless water heater installations and conversions for homes and commercial facilities across Burlingame and the Peninsula. Our licensed, bonded, and insured technicians calculate your property's peak fixture demand to size premium Navien, Noritz, and Rinnai condensing systems, handling gas supply upgrades, direct venting, and isolation valve manifolds for reliable, endless hot water.
Comprehensive Tankless Water Heating Solutions
We design and install high-performance on-demand systems tailored to your specific utility setup:
Whole-Home Gas Condensing Conversions
Ultra-high efficiency condensing units utilize secondary heat exchangers to capture latent exhaust heat, achieving up to 0.95 UEF energy ratings.
Commercial High-Output Cascade Systems
Multi-unit linked tankless manifolds provide redundant, high-volume hot water delivery for apartment complexes, restaurants, and laundromats.
Natural Gas Supply Line Upgrades
High-BTU tankless burners require proper fuel volume; we install dedicated 3/4-inch and 1-inch gas piping to prevent fuel starvation.
Direct-Vent and Concentric PVC Routing
Corrosion-proof polypropylene and PVC direct-vent pipe assemblies route combustion exhaust and intake air safely through exterior walls or roofs.
Dedicated Recirculation Loop Integration
Integrated smart recirculation pumps deliver instant hot water to distant bathroom vanities and master showers without wasting water.
Annual Descaling and Diagnostic Flushes
Routine recirculating maintenance flushes remove calcium and mineral scale from internal copper heat exchangers, preserving factory warranties.
Our 4-Step Tankless Conversion Workflow
Peak Demand and Gas Flow Calculation
We audit your property's simultaneous fixture flow rate (GPM) and gas line pressure to size the optimal BTU rating for your home.
Safe Removal of Existing Storage Tank
We isolate power, gas, and water lines, drain the old bulky tank safely into exterior drains, and haul away the obsolete unit for recycling.
Precision Wall Mounting & Mechanical Hookups
We anchor the tankless unit to wall studs, install dedicated intake/exhaust venting, run gas piping, and connect brass isolation valves.
System Calibration & Homeowner Orientation
We fire the burner, calibrate gas manifold pressures, verify temperature settings on the digital controller, and explain routine operation.

Is Your Property Ready for a Tankless System?
Switching to a tankless water heater is an ideal investment for families tired of running out of hot water, or property owners looking to reclaim floor space. While upfront installation involves proper gas line sizing and dedicated exterior venting, the long-term energy savings and 20-year lifespan make it an exceptional upgrade. Our master plumbers inspect your current gas meter capacity and electrical panel to verify seamless compatibility.
Frequently Asked Questions About Tankless Water Heaters
Will my current gas line support a tankless water heater?
Tankless water heaters consume between 150,000 and 199,000 BTUs during active firing, requiring an adequate gas supply. Our technicians evaluate your existing gas pipe diameter and meter rating to ensure code-compliant delivery or install dedicated larger line feeds.
How often does a tankless water heater require maintenance?
Due to mineral content in municipal water, tankless heat exchangers should be flushed and descaled once every 12 to 18 months. Regular maintenance preserves energy efficiency, prevents diagnostic error codes, and protects manufacturer warranties.
How much physical space does a tankless water heater save?
A tankless water heater measures approximately the size of a carry-on suitcase and mounts directly onto a wall. This design frees up roughly 10 to 15 square feet of usable floor space in your garage, basement, or utility closet.
Do tankless units provide hot water instantly at the faucet?
Tankless units heat water continuously as it flows through the unit. To eliminate the time it takes for hot water to travel from the unit to distant plumbing fixtures, we install units featuring integrated internal recirculation pumps.
Are building permits required for tankless retrofits in California?
Yes, California plumbing and mechanical codes require building permits for gas line modifications, venting routing, and water heater swaps. Power Plumbers and Drains manages all permit paperwork and city building inspections.
