Tank vs. Tankless: Which Is Right for You?
Tank water heaters store 40-80 gallons of hot water ready for use. They cost less upfront ($800-$1,500 installed) but have higher operating costs and shorter lifespans (8-12 years). Tankless units heat water on demand, never running out during long showers. They cost more initially ($1,500-$3,500 installed) but last 15-20 years and use 24-34% less energy for typical households. We'll assess your household size, hot water usage patterns, and gas/electric availability to recommend the best fit.
Proper Sizing Matters
An undersized water heater can't keep up with demand; oversized units waste energy. Tank sizing depends on first-hour rating and peak usage. Tankless sizing requires calculating flow rate (GPM) for simultaneous fixtures. A family of four typically needs a 50-gallon tank or a tankless unit rated for 8+ GPM. We'll calculate your specific needs during the estimate.
What to Expect During Installation
Installation typically takes 2-4 hours for like-for-like replacement. We drain and remove your old unit, inspect connections and venting, install the new unit, connect water and gas/electric lines, test operation, and haul away the old tank. Tankless conversions may require electrical upgrades or gas line modifications, adding time and cost. All work meets local code requirements with permits pulled when required.
