Water Heater Replacement FAQ for San Antonio

Tank or tankless?

Tanks are cheaper upfront ($1,200–$2,500 installed). Tankless costs more ($2,800–$5,400 installed) but lasts 20+ years and provides endless hot water.

How long does installation take?

A like-for-like tank swap takes 2–4 hours. Tankless conversions can take a full day due to venting and gas-line work.

Are heat-pump water heaters worth it?

In warm climates, heat-pump (hybrid) units cut water-heating energy use by 50–70%. Cold-basement installs reduce efficiency.
