Please contact me to discuss details...   This is a simple and cost effective solution to a difficult problem. This heat exchanger coil will enable you to enjoy the benefits of solar heated hot water at a fraction of the cost of changing the whole hot water cylinder.   You can start to benefit from solar heated water without the need to spend thousands of pounds, you can make a simple solar collector by taking a standard domestic radiator, painting it black and putting it in a box with a glass or plastic cover, then by pumping water through the radiator, the water in the system will be heated by the sun, this is then pumped through the solar immersion coil where the collected heat is transferred into your hot water cylinder, simple and free.....   This unit will convert a standard single coil hot water cylinder to a solar ready dual coil cylinder. Don’t spend hundreds of pounds replacing a perfectly good cylinder when this will give you the same results.   Fabricated using the highest quality annealed copper tube; this will replace your existing electric emersion heater element. This will allow you to collect heat from a solar panel or wood burner and use that energy to heat the water in your hot water cylinder.   Each coil is hand made and pressure tested before being dispatched; every care is taken to supply you with a top quality item.   It can be supplied in two standard lengths to suit the existing cylinder     ·       Top entry approx. 800mm long ·       Side entry approx. 350mm long   Please specify when ordering which length you require. Custom lengths can be made to suit your needs.    This heat exchanger coil is designed to be used in indirect solar systems. This will allow the use of antifreeze solution in the system to protect your collector (solar panel) in the event of extreme temperature drop. This is the preferred method of most solar installations.  Please email me with any other questions you may have.   I have had enquires about non vented mains pressure cylinders, as a result I can supply a heat exchanger to suit the 1 3/4" bsp thread on these units, these cost £99 buy it now as the fitting is non standard and has to be manufactured. If you wish to purchase one of this type use the "buy it now" button and specify the 1 3/4"bsp thread.   The 800mm coil is made using 10mm diameter copper tube, there is approx. 5 metres of tube used in the unit giving a great amount of surface area for the heat to transfer.         Thanks for looking....   r hot water heating cylinder free hot water carbon neutral eco friendly solar panel solar panel home build solar hot water system solar collector enviromently friendly its not easy being green cheap hot water green house gas heat exchanger heat converter dual coil twin coil secondary coil emmersion heater immersion heater imersion.wood burner wood stove wood boiler Place a Bid!
