If your water temperature is too hot or too cold, your water heater may not be doing its job. Smelly water can be a sign something is wrong with your water heater, too.

What’s the difference between a tankless water heater and a traditional one?

Tankless water heaters are just that, tankless. They heat water on-demand, whereas a traditional water heater stores gallons and gallons of hot water to use when you turn on a faucet or the shower. Tankless saves space, saves water, and reduces electricity or gas bill depending on the unit you install.

I highly recommend Mainstream

I had the honor and privilege of having Cody Bradley come out to my house chat with me about heater water options! Cody is knowledgeable, enthusiastic, professional, and all-around a great person. From start to finish, he was about my satisfaction as a customer. His passion about the mechanics of waters heaters and plumbing made me excited to learn more and consider future options of where to invest in my home. I ended up choosing a tankless water heater option. He walked me through all the affordable financing options, which made everything painless. I’d highly recommend Cody Bradley and Mainstream Home Services.
