   This was common once, but IIRC regs changed requiring new builds (or   
   re-wires) to have it on a radial.   
      
   IIRC, the concept of a ring requires diversity - ie no continuous high   
   loads. Most domestic high loads are for fairly short periods of time. But   
   heating usually more constant. Water heating is sort of in between - hence   
   the regs changing.
