Water Heaters questions, answered by experts

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

How long do water heaters last? The average tank-style hot water heater will last 8 to 12 years, while a tankless water heater may last up to 20 years. Large families that use a lot of hot water will put more stress on the unit, potentially shortening its lifespan. Regular maintenance and repairs can lengthen the unit’s lifespan.

How long a water heater lasts depends on the type. A conventional tanked water heater has an average lifespan of eight to 12 years. Tankless models typically last a little longer, anywhere from 10 to 15 years. Regular maintenance can help you extend the life of your water heater and keep operating costs in check.

When wondering what size of breaker for a water heater is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.
