Tank vs. Tankless vs. Heat Pump
An honest look at the three main types. We help you pick the one that fits your home and your water.
Tank
- Lower upfront cost, straightforward maintenance
- Bradford White units installed from $2,389 at Paws
- Hard water demands flushing every 3 to 5 years without filtration
Tankless
- On-demand efficiency and longer lifespan when maintained
- Higher upfront cost, from $3,300 at Paws
- More scale-sensitive: a softener is a strong companion
Heat pump
- Most energy-efficient option, well suited to San Diego’s climate
- Higher installation cost, lower operating cost over time
- Same hard-water caveats as a standard tank
