Traditional storage tank water heaters are also known as atmospheric or conventional water heaters. The units both store and heat water inside of a large, insulated tank, usually made of steel. As you use hot water, the tank registers this and creates more.

Tankless water heaters — also called demand-type or instantaneous water heaters — do not store hot water. Instead, when a faucet is turned on, a gas burner or electric element heats the water as needed.

Most jurisdictions require you have a permit before installing a water heater due to changing codes and various safety hazards associated with the installation process. In some cases, you may need two separate permits: an electrical permit and a plumbing permit. These permits are usually not difficult to obtain. SMO Energy is happy to handle the permit process for you.

Please remember, a licensed technician with the proper training, experience and knowledge is the only way to ensure your water heater is installed correctly and safely and with the proper permits. 

A heat pump water heater uses electricity to move heat rather than generate it. Many heat pump HVAC units are dual purpose: They can heat your home and your water. It takes less energy to move heat than it does to generate it. Therefore, heat pump water heaters are more energy-efficient.

Gas water heaters use either natural gas or propane to heat water. For gas water heaters to function, their pilot light must remain lit. Compared to electric water heaters, gas water heaters typically have a quicker recovery rate as hot water depletes. Due to potential hazards, proper ventilation is crucial when using a gas water heater.

R-value refers to the measure of thermal resistance regarding insulation. A high R-value indicates a high level of insulation effectiveness. Tanked water heaters rely on proper insulation to keep water heated while in storage. There are several ways to boost R-value, including the use of water heater insulation blankets.

If your water heater is not working, it may not always mean you need to replace the unit. If your water is too cold, too hot, is taking a long time to heat or leaks, it could mean a few minor repairs are in order. If these problems worsen or persist or are accompanied by other symptoms, it may be time to think about replacement. If you begin noticing these problems, we recommend calling a certified technician to look at your water heater as soon as possible.

Not always. Sometimes a leak can be repaired easily by a technician. Other times, a leak can be indicative of a more significant problem with your unit. The first step is to identify whether the water you see is indeed a leak or just condensation. If you have found a puddle of water, inspect your unit for any dripping or rust. Dry the puddle and monitor it closely. If water continues to pool, a leak is likely.

In the event of a leak, contact a reputable water heater repair and replacement company. If left ignored, leaks could turn into more significant or costly problems. Water damage to your home can be a significant cost to repair, but can be avoided by maintaining your tank and having it assessed by a professional when needed. Trained technicians will assess the situation and determine whether your leak is cause for concern. 

Although it is very uncommon for a properly maintained water tank to explode, some circumstances can lead to a potentially dangerous eruption. Three causes for hot water tank explosions are:

• Sediment buildup: If your water is brown or dirty, this could be a sign of sediment buildup inside your tank. Sediment can form from hard water as it is held in storage. Regular maintenance keeps your tank clear of buildup.
• Gas leak: If using a gas water tank, there is the possibility of a gas leak if valves become loose or are improperly installed. In addition to explosions, gas leaks can also be hazardous to the health of your family.
• Too much pressure: Pressure buildup happens in your hot water tank if the temperature and pressure relief valve malfunctions. This valve is responsible for releasing excess pressure buildup and should be checked regularly.

If your water heater is leaking from the bottom element, it could be due to a leaking drain or pressure relief valve or a leaking tank. Inspect your water heater’s valves and be sure they are tight. If the problem persists, you may need a valve or tank replacement.

A water softener itself does not typically cause low water pressure, but blockage can occur if your water softener’s resins need replacing. A plumber can help you identify whether your low water pressure is a result of softener resins or a problem with your tank.
