American Heat AH-18 Whole House Tankless Water Heater 

Our custom manufactured filter is designed specifically to protect, extend the life and performance of our tankless systems. “White Death” is a term used in tankless technology to identify the calcification of heating elements, internal water components and heat exchanger failure. As mineral deposits pass unfiltered thru a tankless heater the end result is “White Death”. By utilizing our filter, “White Death” is virtually eliminated by 99%.

This valve system is required for maintenance purposes and by most building and zoning plumbing codes. By allowing you to completely shut of the water flow to the heater and cut off any back pressure from the outlet side of the water line without affecting the flow of water to the rest of your house. These valves play an important role by allowing you to service the heater if needed, replace the pre-sediment filter cartridge and winterize as if need be. Additionally you can use these ball valve to precisely balance water pressure to your heater unit without the need of using a costly pressure regulator and maintain proper GPM flow without restrictions to unit. Two ball valves are required per unit.

A necessary component vital with any water heating apparatus. Our pressure relief valve is custom designed for our tankless system. The pressure relief valve is designed to protect your water line and heater (in the event) of over-pressurization which can lead to costly ruptured water lines, heater damage and internal water flooding within your home. Installing our pressure relief valve will eliminate these potential hazards 100% altogether and total piece of mind. Over the counter or traditional tank type pressure relief valves sold in most hardware stores CANNOT be used with our heaters as they will simply not work properly with a tankless system.

This component must be used between the electrical power line(s) from breaker panel to heater unit (place right below heater). The disconnect is a MUST have for proper amp and volt draw. The disconnect also provides a safety pull-out power interrupt. Refer to our installation diagram for proper placement. Please note that the use of wire nuts, braiding of wires and or plug and socket are NOT to be used with our units and will void warranty.

Simply put, you need to use the proper cable to install your heater. The truth is that without the right size wire the heater will not work correctly and you will void your warranty. Some heaters require 6/2 wire while others require 8/2. We sell this wire by the foot so you have no waste. Please specify the wire type on the listing page.
