"Jesse removed old baseboard water radiators in our bathroom. This was the start of a bathroom remodel. When bathroom was finished he came back and installed a new and much smaller baseboard radiator. He was friendly, efficient, came on time, cleaned up any mess and all around very professional. Very happy with his work! Would highly recommend him."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

While heat pump water heaters are more expensive than gas-powered water heaters, the ROI is higher for heat pump units. Not only are heat pump water heaters more energy efficient, meaning immediate savings on your energy bill, but they also last longer than traditional gas versions, meaning you won't have to buy them as often.

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

Age: A water heater older than ten years is approaching the end of its typical lifespan.
Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.
Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.
Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.
Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.
Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.

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.
