More info please. We are having a new boiler system put in and though we
can't afford a whole solar system, can't quite stretch to Jupiter ;-) this
year we are specifying a solar compatible dual coil tank with a view to self
installing the rest next year.

Mary used a Solartwin panel, for which you wouldn't need a new
cylinder, though the existing one must have proper insulation. For
DIY this has the advantage of minimum installation time and effort.

For a more involved DIY project Navitron are one source of useful
bits.
