The latest range of marine water heaters are of excellent quality and have a very attractive price, particularly when one realises that the standard unit incorporates an electrical heater element, an adjustable thermostat, stainless steel mounting brackets, safety valve & drain valve.

This unit has two heating coils instead of the standard one which allows the water to heat at a faster rate.

Thanks to the large surface area of the copper heat exchanger/coil A.T.I water heaters have the ability to produce a large output of hot water.

Heat exchanger surface area: 2.100cm2 (each coil)

Measurements:
Diameter: 320mm
Length of Body: 985mm

All Models give very high performances and efficiency and they are equipped with the following standard components;

•     Copper Heat Exchanger: a wide exchanging-surface allows a large production of sanity hot (even with very small temperature differences), exploiting the heat of the motor cooling water.
  
•     Electrical Heater Element: (220 Volt 50 Hz). It is available in three different outputs (500/800/1200W) and is provided with an adjustable thermostat. It allows hot water production even when the engine is off.
•     External Cast: made of anodised aluminium: it is suitable for nautical usage;
•     Thick Heating Insulation: made of expanded polyurethane with closed cells; it reduces the heat loss to 1'C per hour in 24 hours;
•     Magnesium Anode: it protects the tank against galvanic corrosion.
•     Strong Stainless Steel Brackets: they allow a solid, safe and very easy installation;
•     Brass Flange: it permits inspections of the interior of tanks;
•     Safety valve: it protects the tank from possible excessive pressure.
