Bosch Aquastar Tankless Water Heater 2400E

Endless hot water for 2 major applications at a time

What does Direct Vent or Room sealed mean? The 2400E can be installed in a small space with the ability to take in air from the outside via a 3 inch intake vent. The Bosch AquaStar 2400ESX can be vented vertically or horizontally to the outside. The 2400E requires a dedicated 3" stainless steel single wall vent pipe. Other vent types will void the warranty and present a health hazard.The 2400E also requires an electrical connection for the electronic ignition.
