Jacuzzi direct vent Tankless water heater
Carefully plan the location of your new tankless water heater:
Modern power-vent and direct-vent tankless water heaters make on-demand hot water, but they do require more combustion air because these models use an electric fan to add air to the flame which in turn makes much higher BTUs than the traditional tank type heater. Direct-vent models are the latest evolution in this technology.
An EZ Tankless direct vent hot water heater features the latest technology, it is called BEST. (Balanced Exhaust System Technology) A tankless hot water heater needs an ample supply of combustion air. If you want the best one, it should be a direct-vent model that draws the intake combustion air supply from outside the home so as not to disrupt the interior atmosphere of the room in which it is mounted. Keep this in mind that a direct vent tankless heater does not extract air from the home. Therefore, regardless of the efficiency rating of your choice in tankless heater, if it is not a direct-vent model, you must realize that your home will lose heat (and air conditioning) to any tankless model that uses room air for combustion. If your current tank type heater is located in your living space, it also extracts heat from the home. In fact if you look at the top of a typical tank type heater, you will see an air gap between the heater body and the vent hood that leads into the exhaust. This opening is to promote the natural updraft for the exhaust. We all know hot air rises, so just imagine that this opening is always extracting heated air from your home. For this reason the EZTankless direct-vent models with BEST exhaust technology are absolutely the latest and most efficient tankless heaters available and are not extracting heated (or cooled) air from your home. But by design are almost always mounted on an exterior wall to have easy direct access to outside air and an easy and direct exhaust outlet.
