Dobson has installed and replaced water heaters across Sterling and Northern Virginia since 1975, and we help you pick the size and type that truly fit your household — then install it safely and to code.
nTank or tankless, gas or electric, we handle it all with honest, upfront pricing and financing available through Wells Fargo to make the upgrade easier.
Choosing the Right Water Heater
Every home is different, and the best water heater depends on how you use hot water. Our install service covers:
Tank versus tankless. A traditional tank stores and heats a set amount of water and usually costs less to install. A tankless unit heats water on demand, saves space, lasts longer, and can lower energy use — great for busy Northern Virginia households that never want to run out. If tankless sounds appealing, our tankless water heaters page digs into the details. Getting the size right. Too small and you run cold; too large and you waste money. We factor in your household size and hot-water habits to match you with the right capacity.
A few common questions. How long does installation take? Most standard replacements are finished the same day. Can I switch from tank to tankless? Often yes — we will assess your gas and venting and let you know. What if my current unit can still be saved? Check our water heater repair page and we will give you a straight answer.
