Running out of hot water, waiting for the tank to reheat, or paying to keep 50 gallons of water hot 24 hours a day – these are problems a properly installed tankless water heater solves permanently. A Clear Choice Plumbing and Heating provides expert tankless water heater installation and repair in Aurora CO.
Aurora is one of the fastest-growing cities on Colorado’s Front Range, with a diverse housing stock that ranges from 1970s-era homes in Mission Viejo and Centrepoint to new construction in Tallyn’s Reach and Saddle Rock. Across all of these, one local factor stands out for water heater performance: Aurora Water’s moderately hard water supply. The mineral content in Aurora’s water accelerates sediment buildup in conventional tank water heaters and scale deposits in tankless heat exchangers — making proper installation and annual maintenance more important here than in softer-water markets.
A tankless water heater — also called an on-demand water heater — heats water only when a tap opens, delivering unlimited hot water with 90–98% efficiency versus 60–70% for conventional tanks. At A Clear Choice, every Aurora tankless installation begins with a full site assessment: we evaluate your gas line capacity, peak hot water demand, venting configuration, and water quality before recommending a unit. That means the system is correctly sized, properly installed, and set up to handle Aurora’s water conditions from day one.
Aurora Water's supply carries moderate mineral hardness — calcium and magnesium that deposit as scale inside tankless heat exchangers over time. Scale reduces heat transfer efficiency, eventually triggering flow errors and unit shutdowns. Annual descaling is strongly recommended for Aurora tankless systems, and we factor this into every installation with the right inhibitor treatment recommendations and maintenance schedule.
Aurora's larger-than-average household sizes and high-elevation water temperatures (ground temperature affects incoming water temp) mean sizing a tankless unit correctly requires local knowledge. An undersized unit produces cold water under simultaneous hot-water demand. We calculate your actual peak load — not a one-size-fits-all catalog recommendation.
Tankless water heater installation in Aurora requires a permit and city inspection. Work performed without permits creates insurance liabilities, complications during property sales, and — in the case of gas line work — genuine safety risks. We manage the permit application, coordinate the inspection, and provide you with all documentation.
Tankless water heaters require 150,000–199,000 BTU of gas flow — significantly more than a conventional tank (30,000–40,000 BTU). Most Aurora homes built before 1990 have gas supply lines sized for the lower-BTU appliances of that era. Without upsizing the relevant gas line section, the tankless unit starves for gas under full load, producing temperature instability. We assess and quote any required gas line work before installation begins.
Converting from a conventional tank to tankless requires reconfiguring the venting system. Direct-vent units need a two-pipe system through an exterior wall; power-vent units use existing indoor air with a powered exhaust. The right choice depends on your home's layout, and installing the wrong type leads to condensation, back-drafting, and code compliance issues.
Tankless systems that stop producing hot water are usually experiencing flow sensor errors, scale-blocked heat exchangers, ignition failures, or gas supply issues — not always unit failures. We diagnose Aurora tankless systems accurately before recommending replacement, preventing unnecessary equipment costs.

For most Aurora homeowners planning to stay in their home 5+ years, yes. The higher upfront cost vs. a conventional tank replacement is typically offset within 4–7 years through energy savings — tankless units operate at 90–98% efficiency vs. 60–70% for tanks. Aurora’s hard water makes annual maintenance more important here than in softer markets, but with proper descaling the unit will last 20+ years versus 8–12 for a tank. You also eliminate the ‘running out of hot water’ problem permanently.
Total installed cost for a residential tankless installation in Aurora typically runs $1,800–$3,500 — including the unit, gas line assessment and any required upgrade, venting, installation labor, permit, and old heater disposal. Higher-end condensing units with built-in recirculation (like Navien’s NPE series) fall toward the top of this range. We provide an itemized all-in quote after the site assessment.
Most tankless failures in Aurora are caused by one of four things: scale buildup in the heat exchanger (especially if annual descaling has been skipped — more critical in Aurora due to hard water), a flow sensor error from a partially closed supply valve or debris in the filter screen, an ignition failure, or a gas supply issue from a partially closed shutoff. Check the unit’s error code display and note the code before calling us — this significantly speeds up diagnosis.
Annual descaling is recommended for Aurora tankless systems due to the area’s moderately hard water. Without it, calcium and magnesium scale progressively coats the heat exchanger, reducing efficiency and triggering flow errors. The descaling process — circulating a food-grade white vinegar or commercial descaling solution through the heat exchanger — takes approximately 1 hour and should be performed by a licensed plumber to maintain manufacturer warranty coverage.
Whether you’re replacing a failing conventional tank and want to upgrade to on-demand hot water, your existing tankless system is throwing error codes, or you’ve been planning this upgrade for years — A Clear Choice provides the accurate assessment, correct installation, and Aurora-specific expertise your home needs.
