Product Overview

The IHeat Pro-Performer AHS18-D is built for applications with more than 1 bathroom in the Southern States where the incoming water temperatures no lower than 65 degree F and can be used for 1-1/2 bathroom in the colder climates where the incoming water temperature is above 45 degree F. Because the IHeat Pro-Performer continuously monitors all real time data collected 60 times a second through a range of sensors. It automatically adjusts to any application you may have, for example floor heating, multiple units in series and recirculation configurations. The IHeat Pro-Performer boasts a 3/4 in. inlet and outlet which makes it a breeze for high flow applications. Using ASTM 304 Stainless Steel enclosure and heat exchangers ensures long lasting performance with no sediment build up or rust.

  • Install the IHeat AHS18-D near the hot water applications to save water by cutting down the wait times for hot water

I bought this system about 2 months ago and installed it myself but I'm a licensed electrician. I would definitely make sure you use a licensed electrician. This unit requires at least a 200 amp service panel, you will need a 125 amp breaker in the main panel and 3ea-50amp breakers in your sub-panel. Wire size from main panel to sub-panel will be 2 gauge and 8 gauge from sub-panel to your hot water heater. I live in the Pacific Northwest and this unit works perfect for my whole house needs. You will not be disappointed if you purchase this unit and Great Savings on my energy bill.

            Replaced 4 of these in 9 months all under warranty but not worth the hassle. Cheap Chinese plumbing and electrical components as confirmed by their staff. Pipes were stainless instead of copper. Not a good idea. Heaters developed leaks. The last one after only 1 week. If you purchase, plan to become an expert in water heater replacement.
