"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."

Water Heaters questions, answered by experts

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

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.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.

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.
