"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"Ryan was very capable, shared what he was doing, made a suggestion that I took for improving the gas connection (informing me in advance of the additional cost), and also provided info about my heating system. I expect to have him return for maintenance on my high-tech boiler/water heater."

"I couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

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.

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

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.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.
