sime format, starts stops repeatidly when heating water.

[sram]

hi all,

as u can see im new ,live in an apt for last 4 years,we got it new,hava a sime format gas boiler,so ,when i want the heat on turn on as norm and works as should,but when i want to heat water have to turn stat down and the boiler starts and stops repeatidly maybe 5 secs on 5 secs off,maybe this is normal,but seems very labour intensive on the boiler ,as far as im aware other boilers in the block do the same,its been like this from the start but people say its a bit stranga that it does this,and now im thinking it might be plumbed incorrectly,all replys welcomed........................

sounds like its faulty,if its a combi,problems that will cause this are plate heat exchanger,diverter or aps switch,thermistor call in a gsr engineer
