Frequently Asked Questions

Question: What does DeHart Plumbing, Heating & Air offer for tankless water heaters?
Answer: DeHart provides professional installation, replacement, repair, and maintenance of tankless (on-demand) water heaters. They help choose properly sized gas or electric units for your household and perform installation with licensed technicians.

Question: What are the advantages of going with a tankless water heater — according to DeHart and general industry guidance?
Answer: Tankless water heaters heat water on demand, which eliminates standby heat loss and can reduce energy use. They deliver a continuous supply of hot water, save space because they are compact and wall-mounted, and generally last longer than traditional tanked units.

Question: What are the potential drawbacks or limitations of tankless water heaters?
Answer: A tankless unit may struggle to supply enough hot water if multiple fixtures run simultaneously due to flow-rate limitations. They also typically have a higher upfront cost and may require upgrades to plumbing or electrical or gas infrastructure.

Question: How does a tankless water heater compare to a traditional tank-type heater in terms of lifespan and efficiency?
Answer: Tankless water heaters tend to have a longer lifespan, often 20 years or more, compared to around 8–15 years for tank-type heaters. They are more energy-efficient because they only heat water when needed, avoiding the energy loss of keeping a full tank hot.
