I always say if you need a special kind of product, you should shop online. That is what I did when I looked for additional vent kit for my home. There are several important reasons why I chose the Bosch AQ4 Horizontal Vent Kit for GWH-425 series tankless water heaters. First of all, I like Hydro-generated ignition. The vent kit is great investment because it helps to increase the life of tankless water heater. The water heater work is taken to a new level of functioning and, being approved by the CSA, the vent has great safety and reliability features. The instructions were pretty straight forward. The price was the lowest that I found on the net. The product was shipped fast and free. Thanks!
