"They were very responsive and honest. He called me and gave me honest feedback about what water heater would be best for my home, as well as price options. Did not feel pressured to make a quick decision. Once I agreed, they came the following day to asses and provide an invoice and the day after that the water heater was installed. Can tell a difference in the heating of the water immediately. Would definitely recommend"

Small jobs welcome

"I hired IHM to install a water heater with permit. Everything was fine until the inspection, which they FAILED. Henry sent the same technician (Andre) that did the job instead of visiting the property himself. Andre, who obviously wasn't familiar with CODE, then said relayed to Henry that the water heater model I provided wouldn't work there and that I had to buy another water heater, AND that they would charge me a higher amount to go do the job again or I would have to submit a Change of Contractor to the city. Turns out the water heater DOES VERY WELL work there but their lack of knowledge has resulted in nothing but a waste of time. CROOKS!!"

"Romain?s Plumbing & Drain Service is the absolute best plumbing & drain company in South Florida. Romain is honest, professional, and takes exceptional care in his work to permanently fix all your plumbing and drainage issues. He is very fair with his prices and he takes pride in his work with high quality repairs. I had a water leak that left me without running water in my house for 2 weeks because of a very bad experience with a different plumbing company. When I first contacted Romain he squeezed me into his schedule that same day so that I would have running water again. He repaired both leaks, replaced the drywall, changed out the water valves, and installed a new vanity. I can?t thank Romain enough for their hard work in fixing the leak and getting everything back up and running and replaced so quickly and skillfully. I wish I had an electrician and hvac repairman like Romain because he was so exceptional in his work. If you ever need a plumber please contact Romain!"

"Excellent work. By Code gave me an estimate to remove and replace my 50 gallon water heater for $1454.00 on Saturday over the phone, then replaced it on Sunday the following day with 2 expert plumbers. They are best and most honest and efficient plumbers in Miami. I highly recommend them and will hire them again for all my plumbing needs."

Water Heaters questions, answered by experts

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.

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500

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.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.
