"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"Stephen was great, my tub backed up with water and my toilet would not flush, turns out my septic field needed replacing. Very responsive, reasonably priced and best of all. I didn’t have to leave my home during the repairs. I’d give 10 stars if I could."

"Water pressure was too high causing an awful noise when toilets flushed and faucets running. Called Angi's list t I find a plumber for an estimate. 5 choices came up. Johnson Brothers was the first on the list. Called and Jacob responded immediately. He was able to come over, access the issue and repair all in the same day. Some sort of pressure valve was needed. Jacob explained every step, as if he were a surgeon explaining the procedure. He checked for leaks, there were none. Finished the procedure and no more awful noise. Plumbing issue solved all in a few hours. Very professional I every way. Highly recommend as far as work done right. Price was reasonable I suppose. But worth the no worry mentality."

"They were quick to reply to my quote request and Blain arrived when they said he would. I noticed my water heater had gone bad around 11:00am and they had the new one installed around 6:00 the same evening. Blain was extremely nice, professional, and respectful and the work seems to be top notch."

Water Heaters FAQs, answered by experts

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

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.
