In-depth guides to help you choose the right product for your home
A heat-pump water heater costs three times less to run than electric resistance and beats every other water heater type on lifetime operating cost in most US climates. It also needs 750 cubic feet of air around it, exhausts cool air into that space, and makes a quiet humming sound. This guide covers what it is, what it costs, and the specific installation realities that determine whether one will work in your house.
Installation costs vary by 4× — from $800 for a like-for-like swap in an easy basement to $3,500+ for a complicated retrofit. The variation is not random; it is driven by five specific cost drivers. This guide breaks down what each driver actually adds, what the right price should be for your situation, and where contractors mark up most aggressively.
The number on the side of the tank — 40 gallons, 50 gallons — is not the spec that determines whether you run out of hot water in the morning. The spec that matters is First-Hour Rating (FHR) for tanks, or GPM-at-rise for tankless. This guide shows how to size both correctly for your household, including the math we use ourselves when we replace a heater for a family member.
