Choosing the right water heater often comes down to how it handles combustion air and exhaust. Two common options—power vent and direct vent—may look similar from the outside, but they differ in how they pull in air, vent gases, and perform in different installation scenarios.

Below is a practical breakdown of how they work, where each is typically used, and what to consider before upgrading or replacing a unit.

How a power vent water heater works

A power vent water heater uses a fan (the “power vent”) to move combustion gases out through the vent system. The key point is that the unit generally draws combustion air from the surrounding indoor space or from a dedicated air intake, depending on the installation and the specific model.

Because the fan assists with exhaust, power vent systems can be a good fi ... Read more »

Water heaters are built for long service, but they don’t last forever. Typical lifespans depend on the type of unit, water quality, maintenance, and installation quality. Knowing how long your system should last—and what warning signs to watch for—can help you avoid unexpected failures and higher repair costs.

Average lifespan: what to expect

For most households, conventional tank water heaters usually last around 8–12 years. With better maintenance and favorable water conditions, some units may reach the upper end of that range or slightly beyond. Tankless water heaters often have longer stated service lives—commonly 15–20 years—though performance and longevity can vary based on how hard the unit is working and how well minerals are managed.

Picking the right water heater can affect everything from your daily shower comfort to your monthly energy bills. The two most common options—traditional tank water heaters and tankless (on-demand) units—work differently, so the “best” choice depends on your household’s hot-water patterns and installation constraints.

Below is a practical comparison designed to help homeowners decide which system better matches their needs.

How each system delivers hot water

A tank water heater stores a reservoir of hot water and keeps it warm until you need it. When you turn on a hot tap, the stored hot water leaves the tank and is replaced by cold water that the unit reheats.

A tankless water heater heats water only when a faucet or shower is running. Instead of storing hot water, it uses a burner or heatin ... Read more »

A “rotten eggs” smell—often described as sulfur or hydrogen sulfide—coming from your tap water is a common complaint. While the odor itself can be unpleasant, the underlying cause matters: it may be something as simple as a temporary plumbing issue, or it could be related to the water source or treatment process.

Hydrogen sulfide is the most frequent culprit. It can dissolve in water and release a strong odor when water is running, especially when hot water is used. People also report that the smell may come and go, worsen after water has been sitting, or show up more in one faucet than the rest.

Common reasons for sulfur (rotten egg) odor

1) Hot water heater problems
Because hydrogen sulfide can build up in heated water, the smell may be strongest at showers or hot taps. A failing anode rod, corrosion inside the tank, or sediment buildup can contribute. If cold wa ... Read more »
