Tankless Water Heater Installation

Tankless Water Heater installation can be a costly investment that you will have to live with for many years. In fact, most water heaters typically last between 10 and 15 years before they require a water heater replacement. That’s why when it’s time to outfit your new home, or replace your old water heater it’s important to consider the cost, efficiency, and longevity of your new water heater.

Our water heater installation experts put together a brief comparison of traditional storage water heater installation vs. tankless water heater installation to help you decide which type of water heater is best for you and your family. We will examine the pros and cons of tankless water heater installation and traditional water heater installation so that you can easily make an informed decision regarding your water future. 

Tankless Water Heater Installation Explained

Tankless water heaters, also known as on-demand water heaters, use high-powered burners to rapidly heat water as it runs through a heat exchanger delivering it directly to your faucets or shower without using a storage tank. There are both electric and gas powered tankless water heaters. Each application may require upgrades. In the case of the gas tankless water heater installation you are required to have a PVC vent installed that penetrates the roof of your home or that you mount it on the outside of the home and purchase a special outdoor tankless water heater which may also require an enclosure and re-working your water supply lines. In the case of installing electric tankless water heaters you may be required to have an electrician upgrade the electrical service to your home or plug, depending on its age and set up.  

Advantages to Tankless Water Heater Installation 

Naturally, having hot water whenever you want it without ever having to wait is a big advantage all on its own.

Since there is no tank to fill and refill, tankless water heaters give you an endless supply of hot water, so it doesn’t matter how many people are using it at any given time.

Another benefit of not having the tank of hot water waiting all the time is lower energy bills, because it is only heated when you need to use it. Many homeowners also appreciate the extra space in their attic or garage after the bulky water tank is removed. 


How are “Traditional” Water Heaters Installations Different?

Traditional tanked storage water heaters are the most commonly found type of water heaters in homes today. In a gas powered setup the components include an insulated tank, typically holding 30-50 gallons of water, a gas control valve and a thermocouple. Alternatively, in an electric setup there is only a water storage tank, two heating elements and a thermostat control. 

A natural gas tanked water heater uses almost 50 percent less energy than the electric variety. However, they do have an upfront cost that is a bit higher than electric models. But the difference is still negligible compared to the lifetime savings generated by the heater. Traditional heaters also feature a temperature and pressure-release valve that opens when either the temperature or the pressure exceeds preset levels.


Tankless Water Heater Installation: Energy Efficiency Explained

Homeowners with on-demand water heaters typically use  50 gallons or less of hot water each day. They also enjoy an average of 25% more energy efficiency over traditional water heaters. However, f you use more hot water daily (around 86 gallons or more), then you may only get to enjoy an additional 8-10% energy efficiency.

Purchasing a tankless water heater will cost you a quite a bit more than a traditional water heater. However, tankless varieties are known to last longer than conventional water heater models which translates to a 20+-year useful life, as compared to storage tank types which last only 10 to 15 years before falling apart due to corrosion or part failure of some sort. Traditional heaters are also prone to failure that causes leaks and could possibly flood your home.  

Why Your Tankless Water Heater Installation Costs More 

The idea of installing a Tankless Water Heater has a ton of appeal to homeowners. As you can see there are many upsides to installing them in your home. However we wish to educate our customers about the process of installing the heater so that you will have a better overall understanding of the ramifications involved in the installation of these heaters. 

Tankless Water Heaters are much different from the traditional water heaters we have today. As such, the process of installing one is a bit different. You cannot just easily swap the traditional heater for the tankless by removing one and hooking the other up. In most cases a new vent has to be ran because the venting for a tankless unit is PVC pipe (in gas applications) and not metal like the traditional heater vent pipe. Additionally, the water hook ups often have to be re-worked and set up properly for the tankless units. Tankless Water Heater Installations also typically require a flush kit to be installed for maintenance purposes. All of these things means more labor and more money, which can make tankless water heater installation a bit more costly than simply replacing your traditional heater.
