Customized Solutions

Researching new tankless water heaters can be a very stressful and confusing process for a homeowner to undertake. Instead, we urge you to allow Paragon Mechanical to eliminate the guesswork as you focus on the things that matter most to you.

The Paragon Standard

Piping Braced with Unistrut

All piping is installed using only the highest grade and quality material. Because of their strength and durability, only closed cell PVC and Type-L copper are authorized for our tankless installations. In addition, all piping will be supported by the Unistrut for strength and a clean appearance, and the gas piping will be sized to ensure your unit will receive all the gas it needs. Our installers are instructed to test your gas meter on every job, and in the event you require a new gas meter, our office is ready to assist you in the upgrade with your gas company. We can help you to fill out the forms and to work with your gas company to have the meter replaced with the properly sized meter.

Fresh Air Intake

To ensure tankless longevity, we provide a termination which allows for clean and proper combustion in the tankless burner compartment. Our concentric termination also provides a clean look on the outside of your home with a simple paintable termination which may be painted to match any exterior. Additionally, to protect your home or business from water damage, insects, and animals, we always seal all penetrations with high grade silicone sealant on the inside and the outside of the penetration.

Exhaust Air

The exhaust for these machines is a critical component of a boiler installation and only approved PVC should be utilized. While unbeknownst to many people, not all PVC pipe is the same, and some open cell DWV piping is not approved for being used as exhaust piping. This is a common deception in our industry because DWV piping is 1/3 the price of the closed cell approved PVC piping. We will provide our customers with only the proper venting material to ensure it will not degrade over time and cause poisonous gases to leak into the occupied space.

Gas Meter

Once your new heater is installed, the technician will check the gas pressures to make sure you have proper gas flow to the unit. In addition, the technician will check the meter for the home, and in the event a new meter is required, our office is ready to assist you in the upgrade with your gas company. We can help you to fill out the forms and to work with your gas company to have the meter replaced with the properly sized meter.


All units are equipped with dedicated circuitry to allow for easy-off operation, if ever needed. At the same time, the units will be equipped with a remote mounted near the unit which may be utilized as a user interface and diagnostic tool for the technician when needed.

Fixtures Tested

As part of our check out process, we will flush your system of any debris and soldering chemicals, then we will test your faucets to ensure the settings are to your preference.

Device Registration

To obtain the proper warranty from the manufacturer, all devices must be registered with the customer’s information and the installation date. During the invoicing process we register your device for warranty.
