Compare / Heat pump vs. gas
Heat pump vs. gas tank water heater
Two different fuels, two different strengths. The right answer depends on your utility rates, your space and how much conversion work your house needs.
| Consideration | Heat pump (hybrid) | Gas tank |
|---|---|---|
| Fuel | Electricity, used very efficiently | Natural gas |
| Operating cost | Depends on local electric rates and use | Depends on local gas rates and use |
| Recovery | Slower in efficient modes | Fast |
| Combustion | None in the home | Burner and flue |
| Install (as a replacement) | Conversion: circuit, gas cap, vent review, condensate | Like-for-like is usually simpler |
| Room effect | Cools and dries the space | Minimal |
| Power outage | No hot water production | Some models operate without power |
A heat pump may make sense when
- You want to move away from on-site combustion
- There’s suitable space with air volume and a drain
- Your panel can support a circuit, or a 120V model fits your demand
- You’re electrifying other appliances
Gas tank may make sense when
- You want the simplest like-for-like replacement
- Fast recovery matters for a large household
- The space can’t meet heat pump air or drainage needs
- Local gas rates make it the better operating-cost choice for you
Installation
Installation considerations
A gas-to-heat-pump conversion involves several trades: electrical, gas line capping, vent evaluation for any remaining gas appliance, and condensate drainage. None should be attempted as DIY.
