Tankless Water Heater Installation in Halifax & Dartmouth

In most cases, no upgrade is needed. For heat pump systems with electric backup, the backup can use up to half of the power in your panel, but the heat pump itself only draws 20–30 amps.

If your backup is a gas furnace, it only requires a standard 110V connection, and the heat pump still uses minimal power. The real “power hog” in most installations is the electric backup heat, not the heat pump itself.

Tankless water heaters are typically the most energy-efficient because they heat water only when it’s needed, rather than maintaining a tank of hot water 24/7. Among them, condensing gas tankless units tend to be the most efficient for whole-home use.

No. A water heater provides hot water for uses like showers, dishwashing, and laundry. A boiler heats water or creates steam to provide central heating to a building. While both use heat and water, they serve different purposes.

A water heater heats cold water and supplies it to taps and appliances in your home. It can do this either by storing hot water in a tank or heating it instantly as it flows through the unit.

Yes, for many households, tankless water heaters are worth it. They save energy, provide endless hot water, and last longer than traditional units. However, they have higher upfront costs, so the payoff depends on your water usage and long-term plans.

Not typically. While the initial installation cost is higher, tankless units are cheaper to operate over time due to their energy efficiency—especially in homes with moderate to high hot water usage.

A well-maintained tankless water heater can last 20 years or more, which is about 5–10 years longer than a traditional tank model.

Electric tankless water heaters use a significant amount of electricity while running, but only when hot water is in use. Over time, they can be more energy-efficient because they avoid standby heat loss common in tank systems.

Yes! One of the main benefits is endless hot water, so you can take as long a shower as you’d like—as long as the unit is sized correctly for your household demand.

Not usually. A properly sized tankless water system provides continuous hot water. However, using multiple fixtures at once (e.g., two showers + laundry) can exceed the unit’s capacity, leading to reduced flow or temperature.

Yes. Annual flushing is recommended to remove mineral buildup, especially in areas with hard water. This helps maintain efficiency and extends the unit’s life.

Yes. Tankless water heaters are designed to stay on standby mode and activate only when hot water is needed. There’s no need to turn them off between uses.
