Common questions

Can I install a tankless water heater by myself?
What is the average cost of installing a tankless hot water heater?

The expenditure associated with installing a tankless water heater is contingent upon several variables, including the chosen model's capacity, the complexity of the existing plumbing infrastructure, and any required modifications to gas or electrical lines. For a precise estimate tailored to your specific needs in Eugene, a complimentary phone consultation with our experts is recommended.

What is the downside to tankless water heaters?

One notable drawback of tankless water heaters is their higher upfront cost compared to conventional tank models, encompassing both the unit itself and the installation process. Additionally, in situations of exceptionally high simultaneous hot water demand, the unit's flow rate might be momentarily exceeded, a factor to consider based on household usage in Hillsboro.

Can you run two showers with a tankless water heater?

Whether a tankless water heater can adequately supply two showers simultaneously is determined by its specified flow rate in gallons per minute (GPM) and the hot water requirements of each showerhead. Selecting a unit with sufficient GPM capacity, evaluated based on your household's typical concurrent usage patterns in Oregon, is essential for satisfactory performance.

How long do hot water heaters typically last?

Traditional tank water heaters generally have a service life of 8 to 12 years, with routine maintenance, including checks on the anode rod and the pressure relief valve, potentially extending this duration. Tankless water heaters, when professionally maintained, can often provide reliable service for two decades or more.

What is a water heater pressure relief valve?

A water heater pressure relief valve (PRV) is a vital safety component designed to automatically release excess pressure and temperature from the water heater tank, thereby preventing catastrophic failure. This device is engineered to open at a predetermined pressure, safeguarding the system and its surroundings in accordance with ASME standards, a critical function for water heaters in Oregon.
