Plate Heat Exchanger

As we manufacture cylinders with both a heat exchanger coil and an external plate heat exchanger, it is important to know the benefits of each to be able to make an informed decision on which is most suitable for your requirements.

 

Our plate heat exchangers are manufactured using copper brazed stainless steel which ensures both product life expectancy and heat transfer rates are optimal.

 

Scroll down to see the full list of advantages and disadvantages for both a coil and a plate heat exchanger.

COIL

 

PHE

 

  • Energy Efficiency     ★★★★★

    The mains water pressure is used to drive cold water through the coil, picking up heat from the surrounding water.

  • Space Requirements     ★★★★

    Being an internal heat exchange method, the coil takes up less cupboard space than the external PHE.

  • Cost to Rectify     ★

    If the coil ever developed a leak due to the inevitable effects of corrosion, and if the cylinder is not too old, we may be able to make a repair which could cost around £100 - £400 depending on the severity of the leak. If the cylinder is too old and deemed ‘uneconomical to repair’ and a brand new cylinder would be required.

  • Corrosion Resistance     ★★★★

    Copper is generally regarded as being more susceptible to corrosion that stainless steel. However this does depend on the quality of the water within and surrounding the coil.

  • Performance     ★★★★

    Although larger coils are available, the kilowatt rating of a typical coil is less than that of a typical plate heat exchanger.

  • Components Included     ★★★★★

    The only components involved with the coil option, are a thermostatic mixer valve, a 1 litre expansion vessel, a pressure reducing valve and a check valve. The PHE option also includes these, as well as some others (detailed in the ‘PHE CONS’ section)

  • Energy Efficiency     ★★★★

    Due to the the design of the plate heat exchanger which focuses on a high surface area, a higher heat transfer rate can be expected over a traditional coil.

     

  • Space Requirements     ★★

    Due to the fact that the plate heat exchanger and all of it's additional components are attached to the external pipework, the PHE takes up more cupboard space than the internal coil.

  • Cost to Rectify     ★★★★★

    If the PHE ever developed a leak due to corrosion, a new one could be purchased and swapped out for around £200 depending on labour costs.

     

  • Corrosion Resistance     ★★★★★

    As the plate heat exchanger is made from stainless steel, it offers a higher resistance to corrosion than copper which is especially useful in acidic water areas.

     

  • Performance     ★★★★★

    The Kilowatt rating of our standard plate heat exchanger is higher than that of our standard heat transfer coil. That is not to say that larger coils and plate heat exchangers are not available on request.

  • Components Included     ★★★★

    As well as a thermostatic mixer valve, a 1 litre expansion vessel, a pressure reducing valve and a check valve, the PHE option also involves a circulating pump, a flow switch and a wiring box. Having more components means more potential for failure as components wear; this can result in added costs in buying and fitting replacements.
