Durham Tankless Water Heaters

Tankless water heaters heat water only when you need it, eliminating standby heat loss associated with traditional tanks. This on-demand operation reduces energy consumption, especially in homes with lower hot water usage. Over time, this efficiency can lead to noticeable savings on utility bills.

With proper maintenance, tankless water heaters can last 20 years or more—almost double the lifespan of traditional tank models. Regular descaling and professional servicing help maintain performance and extend life. Their long-term durability makes them a popular choice for energy-conscious homeowners.

No, tankless water heaters provide continuous hot water as long as demand doesn’t exceed the system’s flow rate. However, using multiple fixtures at once may reduce water temperature. Choosing the right unit size ensures consistent performance during peak usage.

Yes, but it’s important to select a model with a high enough flow rate to meet simultaneous demand. Large households may benefit from installing multiple units or a whole-home system. A professional can recommend the best setup based on your usage habits.

Tankless water heaters can be used with well water, but sediment and mineral content can impact performance. Installing a filtration or softening system helps protect the heater from scale buildup and clogs. Routine maintenance is especially important in homes with untreated well water.

Tankless units are compact and typically mounted on a wall, freeing up floor space. Their small size makes them ideal for tight utility rooms, closets, or even outdoor installations. This space-saving design is a major advantage over bulky tank models.

Electric tankless water heaters won’t operate without power, and gas models with electronic ignition also need electricity to start. Some models offer battery backup or can be connected to a generator for emergency use. If uninterrupted hot water is critical, consider backup power options.

Tankless water heaters should be descaled at least once a year to remove mineral buildup, especially in hard water areas. Cleaning the inlet screen filter and checking for error codes also helps maintain efficiency. Scheduling professional service annually ensures reliable operation and longevity.
