What affects the price
Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.
About this service
A tankless unit heats water directly as it flows through the device instead of keeping a large reservoir hot. You should consider this upgrade if your household frequently runs out of hot water during showers or if you want to reclaim space in your utility closet. Because these units only heat water on demand, they are more efficient than traditional tanks.

What is a water heater expansion tank for?
An expansion tank on a water heater provides a space for heated water to expand. As water heats, it increases in volume. The tank absorbs this expansion, preventing excess pressure buildup in your plumbing system. This protects your pipes and the water heater itself. Call us for installation advice.
