Understanding Tank vs Tankless Water Heaters
Making the choice between tank and tankless water heaters can be a daunting task, especially if you are unaware of the key distinctions between these two systems. Let’s break this down in a friendly and easy-to-understand manner.
Definition of Tank Water Heater
A tank water heater is a traditional variety of water heating system you might be familiar with. It stores and heats a large volume of water (ranging from 20 to 80 gallons) within an insulated tank. The heated water is dispensed as required and replaced with cold water to be heated again maintaining a constant supply of hot water.
Definition of Tankless Water Heater
Contrary to the tank water heater, the tankless system, also called an on-demand water heater, only heats water when you need it. When you turn on a hot water tap, cold water travels through a pipe into the unit where it is instantaneously heated and sent to your faucet. In other words, it does not store a preheated reservoir of water, but delivers hot water on the go.
Basic Functioning of Each Type
The basic functioning of a tank water heater is simple. The cold water enters the tank, gets heated either by a gas burner or an electric element, and is stored until required. When you turn on a hot water faucet, hot water from the top of the tank is dispensed while new, cold water enters the bottom of the tank to be heated.
On the other hand, when a hot water tap is turned on in the case of a tankless heater, the incoming cold water triggers the heating element, be it gas or electric. The water is heated instantly and delivered directly to your tap. There is no need for a storage tank.
Energy Efficiency of Tank and Tankless Water Heaters
The energy-efficiency of a water heating system is a crucial element to consider when buying.
Energy Consumption in Tank Water Heaters
Although tank water heaters are effective in their job, they can consume a considerable amount of energy through ‘standby heat loss’. Since the hot water is stored in a tank, some energy is inevitably wasted on heating the water that is not in use.
Energy Efficiency in Tankless Water Heaters
Tankless water heaters are highly energy-efficient. They do not use any energy until the hot water tap is turned on, eliminating any standby heat loss. By heating water only when you need it, energy consumption can be significantly reduced.
Comparing Energy Efficiency Between Both Types
Comparatively, tankless water heaters are more energy-efficient than tank ones due to the absence of standby heat loss. They can be up to 24% to 34% more energy-efficient for homes that use 41 gallons or less of hot water per day. The savings are further magnified for larger homes that consume more hot water.
Installation Process for Tank and Tankless Water Heaters
Installation processes for both types have their own unique procedures and complexities.
Installation Procedure for Tank Water Heaters
The installation of a tank water heater is generally straightforward and less time-consuming. A professional plumber can help to install it in a few hours without any major changes to your current plumbing system.
Installation Complexity of Tankless Water Heaters
The installation of a tankless water heater is more complex, often requiring modifications to your plumbing and possibly upgrading your gas line or electrical system as well. It’s recommended to hire a professional to ensure safe and proper installation.
Necessary Modifications for Tankless Installation
Owing to the high power demand, a tankless water heater might require larger gas lines, a new venting system, or additional electric circuits. This can potentially increase the installation costs, but it is crucial for achieving the best performance and safety benefits.
Cost Implications of Tank and Tankless Water Heaters
There are both initial and long-term cost considerations to ponder in the tank vs tankless debate.
Purchase and Installation Cost of Tank Water Heaters
Typically, the upfront costs of purchasing and installing a tank water heater are less than a tankless one. However, the continuous energy usage can result in a higher cost in the long run.
Initial Costs Associated with Tankless Water Heaters
The initial costs for a tankless water heater – purchase and installation, are generally higher than a tank system. However, the energy efficiency and longer lifespan mean that the long-term cost might be less.
Long-term Cost Comparison Between Both Types
While tankless systems have a higher upfront cost, they can be more cost-effective in the long run due to their energy efficiency and extended lifespan. Tank units, on the other hand, have a lower initial cost but might result in higher utility bills over time due to standby heat loss.
Lifetime and Durability of Tank and Tankless Water Heaters
The expected lifespan and durability of both heater types is a significant factor to consider when making your choice.
Expected Lifespan of Tank Water Heaters
A typical tank water heater lasts about 10 to 15 years, depending on the quality of water in your area and the maintenance provided.
Durability and Longevity of Tankless Water Heaters
Tankless water heaters, on the other hand, can last up to 20 years or even longer with proper maintenance.
Maintenance Needs for Each Type
Both types of heaters require regular maintenance to function optimally and extend their lifespan. Tank heaters may need more frequent maintenance due to the possibility of mineral buildup in the tank. Tankless heaters, though, may need less frequent attention but require professional service when needed.
Size and Space Considerations for Tank and Tankless Water Heaters
Whether you live in a compact urban apartment or a spacious suburban home, the size of your water heater matters.
