The right choice depends on your household size, fuel source, hot water demand, available installation space, and goals. Thornton Plumbing, HVAC & Electrical consults with homeowners on these factors before making a recommendation rather than defaulting to a single option for every situation.
Water heater installation involves gas connections, water connections, venting, and sometimes electrical connections. Improper installation creates risks including gas leaks, carbon monoxide exposure, flooding, and code violations that can affect insurance coverage. Licensed installation also keeps the manufacturer warranty valid.
Yes. Warranty terms vary significantly between brands and between models within the same brand. Rheem offers some of the strongest warranties in the industry. Big box brands sometimes have restrictive warranty conditions that make claims difficult. Warranty terms are an important factor when comparing options.
Thornton Plumbing, HVAC & Electrical repairs water heaters regardless of brand or where they were purchased. If the unit needs replacement and you want to move to a recommended brand, the team can handle that transition as well.
Yes. Navien offers both. Both versions feature industry-leading efficiency and reliable on-demand hot water. The condensing version extracts additional heat from exhaust gases and is the more energy efficient of the two.
Navien tankless units are significantly more efficient than standard tank water heaters because they heat water only on demand and do not maintain a tank of pre-heated water around the clock. This eliminates standby heat loss, which accounts for a meaningful portion of a tank water heater's energy use.
Yes. The team services water heaters of all brands for repair calls, including units that were installed by other plumbers or that came with the home.

Yes. Consumer feedback and plumbing professional experience consistently show higher early failure rates for big box store water heaters compared to professional-grade brands. Multiple repairs within two years on a unit from those sources is unfortunately a pattern that plumbers see regularly.
Helpful questions include what brands the installer recommends and why, what the manufacturer warranty specifically covers and for how long, how the brand's reliability compares across professional installations, how readily available service parts are, and whether the unit is appropriate for your home's specific setup.
