Definitely, you can install a tankless water heater yourself as it is nowhere written that you can’t do it.
But, before you expedite the installation process on your own it is equally important for you to understand the underlying consequences if things turn out to be bizarre.
Most of the premium quality and high-end tankless water heater brands offer a warranty only if a plumber or technician has expedited the installation process.
Any mistake in installation can lead to an invalid warranty.
Moreover, installing a tankless water heater is a time-consuming and tedious task that MUST BE expedited by someone who has expertise in this field.
Though installation cost is tangible and will definitely increase the overall costing of a tankless water heater still it’s worth it in the long run.
Any loopholes in the installation can adversely impact the performance as well as the lifespan of a tankless water heater.
So, though theoretically there isn’t any harm in installing a tankless water heater on your own still we recommend it to get installed by a CERTIFIED TECHNICIAN in order to prevent any last-minute misadventure.
To add to it, installing a tankless water heater isn’t a DIYer project if you don’t have prior experience in plumbing.
At the same time, it’s equally important for you to understand that there are a number of different sizes and styles of a tankless water heater including propane, natural gas, and most popular, electric variant.
If needed you might have to do slight modifications to your gas line in the case, you’re planning to install a gas tankless water heater.
What I actually mean is, you need to consider a lot of things when it comes to successfully installing any variant of a tankless water heater.
Not to forget, if you’re planning to expedite the installation process on your own then definitely, you need to be well-versed with the process of shutting off the gas supply to the existing water heater as well as disconnecting the tank without releasing any gas.
You might have to hire someone for disposing of the existing tank-styled water properly if you’re planning to upgrade to a tankless water heater.
Once you’re done with the selection of the tankless heater model, you need to install the exact vent that your tankless heater model is compatible with.
The probability is very high that you’ll have to wire in your new tankless unit.
In rarest of the rare scenario, you might have a properly sized power source nearby.
Needless to say, all these tactical tasks will require both wiring expertise and plumbing experience.
For increased demand, you don’t have an option but to upgrade your gas pipeline in the case of installing a gas tankless water heater.
Of course, quite a few installations also require new water lines as well as pressure relief valve discharge lines that require soldering.
And, by any chance you’re successfully expediting the aforementioned steps then the next thing that you need to do is to ensure that the entire installation meets building codes and that your house owner’s insurance will cover any damage caused by potential mistakes.
I hope now you would be in a better condition to decide whether you would love to expedite the installation process of a tankless water heater on your own or you’ll prefer to hire a certified technician.
My main purpose was to update you regarding the know-how of the installation steps.
