22mm solar coil


22mm Solar Coils.

More and more people are now considering installing a solar panel, both to reduce their heating bills and to do something positive towards the environment. A solar panel offers a great way of doing both of these, but the overall cost tends to be one of the main reasons holding people back.
A fair proportion of this cost is replacing your existing hot water cylinder. This needs to be done if you only have a single coil cylinder. The fact remains, if there's nothing wrong with your cylinder, then replacing it seems such a waste as well as hugely expensive.
In this situation then a solar coil may well be the answer.
Add a solar panel circuit to your existing hot water cylinder. The solar coil simply screws into the 2¼" brass cylinder boss. The coil is made from 22mm diameter copper tube for a large surface area, high heat transfer and low flow resistance.

           Size of heat exchangers for solar panels.

          In solar systems with 0.5 Ltr/minute or above flow rate per m2 solar collector,
          there should be no less than 0.2m2 heat exchange area per m2 net absorber solar collector area.

          In solar systems with below 0.5 Ltr/minute flow rate per m2 solar collector,
          there should be no less than 0.1m2 heat exchange area per m2 net absorber solar collector area.
