The prime reason why the installation cost of a water heater so expensive is it requires a lot of specialized installation work. For instance, the water heater should be located near the point of use, and the venting system needs to be installed appropriately to avoid creating air leaks.

Additionally, tankless water heaters are twice the cost of installing a standard water heater. Moreover, a tankless water heater requires numerous specialized components, such as a gas valve and a digital controller, making it more expensive. Consequently, the entire cost of installing a tankless water heater becomes very high, including the plumber’s cost. Most importantly, the installation work must be carried out by licensed plumbers in Stockton with tankless certification.

Factors that affect the installation cost of a tankless water heater

Water heaters play a significant role in the house’s overall plumbing structure. Compared to a standard water heater, the tankless water heater has a higher purchase cost. However, since tankless systems only heat the water you use, their running cost is lower than standard water heaters, which consistently heat a large quantity of water. The entire installation cost of the tankless water heater depends on various factors like unit size, location of the heater, and venting system. 

Water Heater Replacement

The first step is to drain and remove the existing system’s tank. Once you’ve removed it, walls or ceilings might have to be opened to install gas lines or water lines. Consequently, if walls and ceilings are opened, the repairing cost of these areas may increase the installation cost. So, you can see that the installation cost of a tankless water heater costs more than just your old water heater repair in Stockton.

Size of Water Heater

The size of the tankless water heater adversely affects the overall cost. Matching the water heater size to your hot water requirements is essential. If you buy a too-small tank, it will result in cold showers and inadequate hot water, whereas a large tank will waste energy. Therefore, it is imperative to determine the optimal size of the water heater according to your hot water requirements.

Venting

A tankless water heater needs an exhaust system to eliminate the resulting hot water outside. Usually, the vents are of two types. The first is the power vent, which uses indoor air for combustion and releases the exhaust outdoors. The second is a direct vent that requires two vents, as it uses outside air for combustion. Out of two vents, the first one is responsible for bringing in the outside air, and the second one removes the hot air through heavy aluminum pipes. This venting system adds another cost to the final bill, making the installation even more expensive.

What is the average lifespan of a tankless water heater?

Generally, an average lifespan of a tankless water heater is more than twenty years and can last for more if you follow a professional tankless water heater drain cleaning in Stockton. Periodic maintenance and drain cleaning can help in maximizing the water heater’s durability. Moreover, the parts of tankless water heaters are easily replaceable, which adds more years to their life. On the contrary, the standard water heaters can only last for 10-15 years.
