"Louis and his assistants were courteous, on time, efficient, and did a great job finding and fixing what turned out to be multiple leaks. Louis kept us informed through out the process. They even mopped their work area after the leak was fixed. I would highly recommend this company to anyone needing an honest, hard working plumber!"

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

Excellent customer service, Talked to him about some other jobs that we need to have done and we look forward to seeing him again soon. Great Job, IDB!! David & Bonnie"

"Brandon Bing and Steve Lorenz are owner-operators and I found both of them to be skilled in their trade, honest and hardworking The installation of the water heater and solar panels went well and any bumps were smoothed out. I am initially disappointed in the Solar array's electric impact but I have a few trees that I need to take out and I still need to get my FPL net metering installed. At times I am producing more than what I consume so until I get net metering installed I cannot capitalize on overproduction. These comments are in no way a reflection on All American Solar for their work ethic or products. In fact, the array is expandable so that I can add more panels in the future. The Solar hot water heater is fantastic and has saved me about $60 per month off my electric bill. I would gladly recommend All American Solar for your solar panels or a solar hot water project and I would hire them again."

Water Heaters FAQs, 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 well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

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

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection
