The concept of tankless water heaters dates way back. Ancient Greeks and Romans used pipes to heat water as it flowed through them. This idea evolved over centuries, leading to the modern tankless water heaters we know today. But beware – they may give you hot showers, but leave your soul cold and empty.
Drawbacks of Tankless Water Heaters
To address the drawbacks of tankless water heaters, let’s delve into the details of initial installation costs and its limited flow rate. In terms of costs, tankless water heater installation can be pricey upfront. Additionally, the flow rate of hot water may be restricted, particularly in larger households or during simultaneous water usage. By understanding these factors, you can make an informed decision regarding tankless water heater installation.
Initial installation costs
Cost Component and Average Cost Range for a Tankless Water Heater Unit is $800 – $1,500.
Professional Installation can be from $500 – $1,000.
Extra costs may occur for upgrading gas lines or electrical circuits.
Consulting a professional is important to accurately estimate the installation.
Tankless systems offer long-term energy savings.
24%-34% more energy-efficient than storage tank models – resulting in cost savings.
Limited flow rate – perfect for those who enjoy the sound of a dribbling faucet.
Limited flow rate
Tankless water heaters are efficient, yet they have a limitation: flow rate. This means the amount of hot water they can give per minute is limited, which may not be enough for some households or any situation with high demand for hot water.
To better comprehend this, take a look at the below table:
| Flow Rate (Gallons per Minute) | Average Temperature Rise (°F) |
|---|---|
| 3.0 | 50 |
| 2.5 | 60 |
| 2.0 | 70 |
The table shows how the flow rate reduces as the desired temperature rise increases. This implies that if you want a higher temperature rise, the tankless water heater will be able to supply less hot water per minute.
Also, it’s vital to consider that the flow rate can also be affected by other things such as the size and type of plumbing fixtures in your home. For example, if multiple showers are running all at once, the flow rate may drop even further.
Sarah’s experience is a great illustration of this restriction. She recently installed a tankless water heater in her home and was pleased by its energy efficiency. However, when her family had guests over and multiple showers were running, they started to notice a decrease in hot water flow rate. This made them realize the inadequacy of tankless water heaters under high-demand situations.
Traditional water heaters may not save you money, but they are great for horror movie scenes.
