Webasto AT2000ST Premium Marine/Boat Heater Kit
The AT2000ST is the smallest air heater offered by Webasto. The unit will heat up to a 30-foot sailboat and 26-foot powerboat. The AT2000ST utilizes a 55mm hot air duct system, a 22mm exhaust system, and a 3/16" fuel system. This diesel-fired heater is rated to 7,000 BTU and is available in 12 or 24 volt.
The Webasto AirTop (AT series) heaters blow hot air through installed duct to various spaces in the boat. The unit is controlled by a central thermostat that shuts the unit down when the boat's interior has reached the desired temperature. Benefits of an air heater are simple installation and operation as well as quick heat .This simple installation allows the heater to blow hot air into the cabin just after startup without a warm-up period.
When choosing a system to heat your boat, installation requirements should be taken into account. A clean, dry location should be chosen for the mounting of the heater. Once this spot is chosen it should be checked against the parameters of the heater's system. Exhaust run and placement should be taken into consideration when choosing a location for the unit. The AT 2000 uses 22 mm exhaust flex tube that must vent over the side or aft transom of the boat. Location for the thru-hull should be as high (min 36 in.) and far aft as possible to prevent water intrusion into the exhaust system. The AT 2000ST can have a maximum of 7 ft. of exhaust installed with a maximum of 270° of bends. The unit should not have more than 20 ft. of duct installed and should have no sharp turns within 2 ft. of the unit itself. The placement of the heater should conform to these specifications before the installation process begins.
Along with heater placement, placement of the duct for the heater is also important. The AT 2000ST uses 55mm duct that must be installed in such a manner that it cannot be crushed or knocked loose during cruising or boat use.
Once heater placement has been chosen, heat outlet locations should be chosen. All outlets should be located low in the space because heat rises. The main salon should have one 55mm open-only outlet installed and this should be the first outlet in the line. Any other spaces can have an on/off 55mm outlet installed.
