The Isotemp range of Calroifiers/Water Heaters from Indel Webasto

 


Isotemp: High-quality stainless steel hot water cylinders

The Indel Webasto Marine Isotemp water heaters are specifically designed for the use on yachts and boats. Only high quality components are chosen to ensure the best product performance. The marine water heaters are very robust with both the water tank and external cylinder being made of stainless steel.

The Isotemp water heater comes with a brushed stainless steel cover as well as innovative internal design. It achieves its high efficiency by the optimised installation of the engine water coil (and heater coil on twin systems),as well as the immersion heater being positioned in the lowest part of the tank where the water is coldest. This ensures that the internal water is heated evenly, maximising the effectiveness of the tank. The water inlets and outlets have also been specially designed to minimize the mixture of cold and hot water.

Product Specifications:

Extra-long, corrugated coils for high heat exchange efficiency

7.0 bar/100 psi safety valve

Simple winter drain point for easy maintenance

Ultra-thick insulation for industry lowest temperature loss

Thermostat mixing valve available as an option

Standard 750w immersion heating element

Indel Slim Calorifiers

Isotemp Slim Calorifiers 230V


Isotemp Slim is a range of water heaters, available in three sizes, 15, 20 and 25 litres. Isotemp Slim has an exlusive look and design, with brushed stainless steel covers. The highest efficiency is achieved by the engine water heat exchanger, as well as by the immersion heater mounting being positioned as low as possible inside the tank to heat the water where it is coldest.

   

Isotemp Slim Square Calorifier 230V


This slim line, box style water heater has been designed for easy installation in narrow spaces. The Isotemp Slim Square has a capacity of 16ltrs and effectively heats water up via the boat engine or by the electrical heater element if the boat is connected to shore power. The water is heated to above 70°C which enables water to be heated on board at the correct levels for both hygiene and safety purposes.

It can be installed in a variety of positions, making it more versatile than standard models currently available. As with all Isotemp water heaters, the Isotemp Slim square has been constructed with a robust acid proof stainless steel (AISIS 316) and fitted with special components to protect it from overheating.

It also features a safety valve with a built-in two-way check valve, which reduces or prevents water normally forced out by expansion. It also has a drain point fitted as standard to enable easy winterisation of your boat.

At thermostatic mixing valve can be fitted as an option. 

The safety valve is set to 5.5 bar/80 psi on this model.

Indel Basic Calorifier

Isotemp Basic 230V


Isotemp Calorifiers

Isotemp Basic has an exlusive look, with its brushed stainless steel cover, but most important is the internal design. The highest capacity is achieved by the engine water heat exchanger as well as the immersion heater placement. They are positioned in the lowest part of the tank where the water is coldest, to really heat all the water in the tank, which grants an outstanding volume of hot water. The water in- and outlets are also designed for a minimal mixing of cold water into thee hot, by the incoming water. The selected materials are all the best; tank, tubes and all materials in contact with the water are made of acid proof stainless steel AISI 316 and welded with protection gas to eliminate any risk of corrosion. Each water heater is individually leakage tested to 16 bar/230 psi, before delivery.
