There are two main types of tank water heaters, Power Vented (PV) and Conventional Vented (CV).They account for approximately 80% of the tanks in marketplace. The main difference between the two is that CVs vent the exhaust naturally up through the chimney, whereas PVs use a blower motor to vent the exhaust to the side of the house, usually in the alleyway between houses.
- Pro: Long-term Energy and Cost Savings. The main advantage of tankless water heaters is that they are energy efficient and save you money over the long term.
- Pro: Unlimited Supply of Hot Water. Here’s a scenario; you come home from a family beach day and everyone in the house needs to take a shower. By the fifth shower in a row, the hot water is running low, and you’re the one stuck taking a cold shower.
- Pro: Take Up Less Space. If space in your home is limited, tankless water heaters provide a huge benefit. They are usually mounted to the wall and take up significantly less physical space compared to tank-style water heaters.
- Pro: Lower Risk of Leaks and Water Damage. One of the biggest risks with tank-style heaters is, over time, minerals from hard water build-up within the tank which leads to corrosion and eventually leaks.
In order to deliver greater efficiency, water heater manufacturers are embracing new technologies in their ENERGY STAR ® certified water heaters. These water heaters include: Heat Pump Water Heaters (Hybrid): These use advanced heat pump technology to transfer existing heat from the air to help heat water. That makes them two to three times ...
- Storage Tank Water Heater. This is the most common type of water heater found in residential settings, and one that most people will be familiar with. This type of water heater, as the name suggests, stores water.
- Tankless Water Heater. A tankless water heater, unsurprisingly, does not have a tank. Instead of holding water and heating it like a conventional storage-tank water heater, a tankless water heater has hot coils that can heat water up in mere seconds as it passes through the system, giving you hot water on demand.
- Heat Pump Water Heater. Heat pump water heaters operate through electricity. They don’t actually generate heat themselves but instead draw heat from the ground and air around them, then target this heat at the water in their storage tank to heat it up.
- Solar Powered Water Heater. Solar powered water heaters have two parts: an insulated water storage tank and solar panels known as ‘collectors.’ The solar panels collect energy from the sun and then transfer that energy to a heat-conducting system to heat up the water in the storage tank.

- Rumbling. Sediment build-up is a regularly occurring issue with hot water tanks, especially if you live in areas with hard water. These mineral deposits settle inside the tank, causing a range of problems.
- Popping. Popping, like rumbling, is most often caused by limescale and sediment build-up within the tank. The sound is created when steam bubbles form under the sediment and burst as the water heats up.
- Sizzling, Hissing, or Crackling. Sizzling, hissing, and crackling are sounds more commonly heard from electric water heaters. They are typically attributed to sediment build-up in the base of the tank, which can be addressed by annually flushing and draining the water heater.
- Ticking. Changes in water pressure, efficiency-boosting heat trap nipples, and loose pipe straps can all cause ticking noises in and around the water tank.

Sep 11, 2024 · Benefits: The higher output of these water heaters provides more hot water, and the increased efficiency will lower energy costs. Drawbacks: Costs are far higher than standard systems, and these units also require gas lines and exhaust venting. A condensing water heater can cost more than $2,000 just for the unit.
