Top Performer Plus Specific Questions

Do I need to install an insulation blanket?

No. Most new water heaters and storage tanks are highly efficient with respect to the amount of heat loss radiating from the storage tank. This is due to the use of “blown in” polyurethane foam insulation as the insulating method for modern tanks, compared to the fiberglass blanket style insulation used by water heater manufacturer’s largely in the past. As such there is little to no benefit, and very possibly a detrimental effect to efficiency,from installing an insulation blanket on a new water heater or storage tank constructed with foam insulation. If you do decide to install an insulation on your heater or storage tank, please be certain that the access panels, plumbing connections, and relief valves have proper access and clearance.

Is the Vaughn heat exchanger removable?

Yes. The heat exchanger is fully removable in all Vaughn indirect water heaters. The benefit to having a removable heat exchanger is that the coil can be removed for cleaning and de-scaling for improved performance and efficiency when used in hard water applications. It should be noted that the heat exchanger is not removable and the coil cannot be cleaned in many other indirect water heater brands.

Why is dielectric isolation so important?

The unique design of the Vaughn heat exchanger electrically isolates the heat exchanger from the tank by means of a non conductive barrier installed between the two. This provides dielectric isolation between the tank and the heat exchanger thereby eliminating electrolysis between the two due to dissimilar metals. This feature is one reason why the Vaughn indirect water heater far outlasts competitor models.

Is it OK to use softened water with my cement lined tank?

Yes it is OK. A water softener system will not affect the longevity or operation of a Vaughn cement lined water heater tank. A water softener is typically installed when a potable water system has hard water resulting in the need to soften the water. Unfortunately, the salt used in a water softener corrodes the anode rod and exposed steel surfaces of the water heater tank, rapidly causing a glass lined water heater to corrode and leak within a few years. This is an issue for a glass lined water heater due to its reliance on a sacrificial anode, however because a cement lined tank does not use a sacrificial anode softened water is of no concern to the Vaughn cement lined tank.

General Questions

Are Vaughn heaters made in the USA?

Yes. Vaughn water heaters are all made in the USA and our factories located in Connecticut and Massachusets and qualify for incentives under The Buy American Act and the American Recovery and Reinvestment Act (ARRA). For more information go to the following link Here.

Where can I purchase a Vaughn water heater?

There are numerous ways to purchase a Vaughn water heater depending upon the model you desire and your geographic location. The easiest way is to contact Vaughn directly at 978-462-6683 and ask for the sales department where you will be directed to either our local representative or our order entry department for quick and easy ordering.

What code requirements are applicable for my installation?

The installation of water heaters are mostly governed by the Uniform Plumbing Code (or CPC in California), Uniform Mechanical Code, and National Electrical Code. These are standard codes that are used across the United States, and each state can amend them as they wish. To take it further, each city and county jurisdiction has assigned one or more building officials with what is called Administrative Authority. This Authority" allows each jurisdiction the right to interpret the codes as they see fit. Because of this many cities differ on their requirements. Vaughn strongly recommends that you contract with a plumbing engineer who knows and understands the intricacies of the building code requirements for your location.

Is it OK if my plumbing system has plastic pipes (PVC or PEX)?

Yes. All Vaughn water heaters will work with both types of plastic piping.
