"As soon as I went on Angieâ s list they contacted me. He asked for pictures of our hot water heater and all the documentation on it. By the end of the day he sent me a quote for two different models. The night before he came to install the new heater he asked to see it to be sure he would have everything he needed. Mr. Rizzo is an excellent plumber and a pleasure to work with. He covered all the floors I would definitely recommend him. He was a rare find!"

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"Excellent Plumbing was fantastic - he installed a new faucet, vanity, and water filter for me. Super punctual, really professional, very communicative, and paid close attention to detail. Everything's working great. What really stood out was Joe's dedication. He came back to check on the work and found an unrelated issue with my kitchen sink (which was already there). He gave me some great tips on how to fix it. I highly recommend Joe and Excellent Plumbing & Heating for any plumbing work. He's super skilled and has awesome customer service."

"Just Rite Heating & Cooling installed our central air conditioner today. The team of five were on time, courteous, friendly and hard workers. They laid down runners to keep the interior of my house clean. The boss, Eric, explained how each part of the system components worked. Together we worked out the placement of the ceiling registers in each room. After the system was completely installed I was instructed on the how the new thermostat controlled both the old heating system and the new air conditioning system. Best of all the installation was completed in one day!"

Water Heaters questions, answered by experts

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.
