Can I use small/micro bore (10mm) or larger (22mm) pipe work?

Our radiators can be used with existing pipe work which is either narrower (10mm) or wider (22mm / ¾”), though we recommend using 15mm bore pipe as a minimum. Copper/brass Converters or Reducer fittings are freely available at little cost to enable the radiator to be fitted to smaller (10mm) or larger (22mm) pipe work. On larger radiators (those in excess of 2000 Watts) it may prove a problem in balancing the system if using microbore (10mm) pipe. Therefore, we always suggest speaking to your heating engineer or plumber to make sure your pipe work is compatible.
