Smart finish in a brushed stainless steel exterior, the quality of the Isotemp Basic by Isotherm, is not just skin deep. Optimal water heating is achieved in two ways, firstly by an immersed electric heating element (immersion heater) and secondly by utilising the boat's engine water heat (Heat Exchange). Isotemp water heaters may be used with fresh water or salt water cooled engine systems. The immersion heater and heat exchanger are positioned in the lowest part of the tank, providing even thermo cycle heating of the water in the system. The engine water heat exchanger coil is extra long for faster heating, especially handy on sailing yachts, which may run their engine for short periods only. The water inlets and outlets are positioned to minimise mixing of cold water into the hot, by the incoming water.

The immersion heater has been designed to enable easy removal to allow for inspection and cleaning of the tank. The materials used in the construction of the tank are of the highest quality. Acid resistant stainless steel AISI 316 is used for all parts of the tank that are in contact with water. The internal tank is insulated with expanded polyurethane insulation ensuring low temperature loss. The outer cover and mounting feet have been crafted from non-magnetic stainless steel AISI 304. The fixing feet are adjustable to 360º, allowing the tank to be mounted horizontally or vertically.

An optional accessory to the range is the thermostatic mixing valve, 135840, (controls the maximum temperature of water at the tap) which adds to safety, particularly important if having young children on board. The Isotemp range of water heaters by Isotherm have a two year full warranty and a five year limited warranty on the tank.

IMPORTANT NOTICE

Amendments to Isotemp water heaters HXC20, HXC25, 24HXC, 40HXC, 50HXC and 75HXC effective 1st of Feb 2008. Please note that this amendment must be read prior to installation and use of the Isotemp range of water heaters. These amendments, along with other changes, ensure that Isotemp  units comply with AS/NZS 60335.2.21:2002 inc. amendment 1 & 2. Approval number A/10238EA.

N.B. INSTALLATION MUST BE CARRIED OUT BY LICENSED TRADESMEN TO AUSTRALIAN STANDARDS.

1. The water may drip from the discharge pipe of the pressure relief device. This pipe must be left open to the atmosphere.
2. The pressure relief valve is to be operated regularly to remove lime deposits and to verify that it is not blocked.
3. A discharge pipe connected to the pressure relief device is to be installed in a continuously downward direction and in a frost-free environment.
4. The operation of the thermal cut-out indicates a possibly dangerous situation. Do not reset the thermal cut-out until the water heater has been serviced by a qualified person.
5. Danger: failure to operate the pressure relief valve easing gear at least once every six months may result in water heater exploding. Continuous leakage of water from the valve may indicate a problem with the water heater.
6. A temperature operated relief valve must be fitted in the installation - supplied. (This is a requirement for water heaters intended for direct connection to the water mains). Please refer to the illustration on reverse for recommended installation.
