"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!"

"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"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."

Water Heaters questions, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

One of the primary benefits of a heat pump water heater is how cost-effective it is. How much you save will depend on your water usage and electricity costs. That being said, we can ballpark savings for the average home of between $100 and $500 per year. You can increase that savings rate by researching and applying available energy incentives available in your area. If you really want to focus on cost, consider a tankless water heater.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.
