Tank & Tankless Water Heaters
By now just about everyone has heard about high-efficiency tankless water heaters, so you might automatically assume that’s what you should get. That might be true, but instead of blindly jumping in and buying the newer, hi-tech technology, you should first evaluate your own situation.
Endless Hot Water: This is the obvious advantage to a tankless water heater. If you have lots of people who consistently tend to shower at about the same time, tankless can be a huge advantage.
Equipment Cost: Tankless heaters cost about 2 to 2 ½ times MORE than tank heaters. And while there may be some ongoing utility savings, the upfront additional cost is often impossible to recoup in less than 20 to 30 years.
Energy Savings: Tankless water heaters are more energy efficient, although many users report that they actually take longer showers (knowing that the hot water will not be exhausted) which offsets some of the savings.
Maintenance: Tankless systems must be flushed annually to retain their efficiency and prolong their useful lifespan. You can perform the flush yourself, or hire us to do it for you.
In most cases ATS Mechanical suggests a tank water heater installation simply because it is a much less expensive solution that will still get the job done with little discernible difference. Even in cases where hot water tends to run out quickly, we can install a second unit right next to the first one that works in tandem to effectively double your hot water capacity. This is not always an option from a space availability standpoint, and in some cases, still may not provide enough hot water.
However, tankless water heaters are more energy efficient, require less maintenance, and provide and endless supply of water. At ATS Mechanical, we’re happy to install whichever you choose after we evaluate your needs and recommend the most cost-effective solution for water heater installation.
What Size Tank Water Heater Should I Pruchase?
A family of two may only need a 40 gallon water heater. A family of four may need a 50 gallon water heater. A larger family, or a family with members who want to take long showers, may need two 50 gallon water heaters. And any family with a large capacity tub, jet tub, whirlpool etc and several family members may only be satisfied with one or two tankless water heaters. We should talk about your needs to help you make the best choice.
Why Do Tankless Water Heaters Cost So Much More Than Tank Water Heaters?
More often than not the gas piping in a home is not large enough to handle the increased load of the tankless water heater. When the natural gas piping must be increased in capacity there is considerable expense involved.
Why Can It Take A Long Time For Hot Water To Come Out Of The Faucet?
Cold water is standing in all of the piping between the water heater and the faucet you are using. That cold water standing in the pipes must be pushed out of the pipes and replaced with hot water behind it. Flushing out the cold water in the pipes takes time. With a tankless water heater in the Denver metro area, additional time is taken because of the time it takes for a tankless water heater to get started producing hot water.
What Is The Required Minimum “EF” (Efficiency Factor) For Water Heaters?
- For a 40 gallon natural gas tank type water heater the minimum EF = .62
- For a 50 gallon natural gas tank type water heater the minimum EF = .60
- For a tankless type water heater the minimum EF = .82
How Is The Efficiency Factor Is Calculated?
The efficiency factor (EF) indicates a water heater’s overall energy efficiency based on the amount of hot water produced per unit of fuel consumed over a typical day. The higher the EF, the more energy efficient the water heater. The EF is measured in three ways:
- Recovery efficiency – How efficiently the heat from the energy source is transferred to the water
- Standby losses – The percentage of heat loss per hour from the stored water compared to the heat of the water
- Cycling losses – The loss of heat as the water circulates through a water heater tank, and/or inlet and outlet pipes
