Water heater with vs without tank: what are the differences?
Is your water heater due to be changed? And you hesitate between with or without a tank? Here are some comparisons to help you make your choice:
| Water heater with tank | Tankless water heater | |
|---|---|---|
| Capacity | Limited to tank size. | Unlimited (on demand). |
| Space requirements | Bulky and requires a dedicated space (basement, laundry room). | Compact and wall-mounted, the tankless water heater frees up useful space in the home. |
| Energy efficiency | Tank: Continuously heats water to maintain temperature, even when not in use. This results in a loss of standby power. | Tankless: Heats water only when needed, making it more energy efficient and reducing gas bills over time. |
| Price | Purchase: starting at $1,000 (estimated price, without installation). Rental: starting at $28.99/month* (with installation). |
Purchase: on average starting at $1,600 (estimated price, without installation). Rental: starting at $36.99/month* (with installation). |
| Useful life | 10 to 15 years but often limited to 10 years by insurance provider. | On average, 20 years or more. |
| Other benefits | Less risk of corrosion and leaks than a tanked model. |
