What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

An expansion tank protects your plumbing system from pressure spikes caused by thermal expansion as water heats up. We install this tank on the cold water supply line, which helps prevent leaks and extends the life of your heater. You need this installation if your home has a closed-loop plumbing system or if you experience relief valve dripping. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Most residential units in Winston-Salem last about 8 to 12 years with regular maintenance. Hard water throughout Forsyth County can shorten this lifespan significantly by corroding the tank lining. If your unit is approaching a decade of service, it is wise to have a professional inspect the anode rod. Call us to discuss your specific unit age.
