hi .this is a good one.just moved into a french house where someone fitted at great cost a sime combi boiler about 4 years ago.the english guy who fitted this has left the country so i would like some advice please.the only detail i have is on the pump it says 03f2b va55 tf95 6 bar max .i know this is a bit vague.2 controls on the front 1 hot water the other ch.also a dail with temperature and bar on the bottom .the bar reads 1;5 when the system fires up the temperature gets up to 70.the pump is running ok the pipe to the rads starts to get warm about 6 inches down the pipe from the boiler and thats it!the pump continues to run but the rads do not get warm.i have to say this house has 10 very large rads using 22 mm pipe under the floor and it is a big house.is that the pump is not man enough for the job?thanks for any help .john

hi mate the pump should be more than enuf to at least push to sum rads hows the hot water? if that's ok usually means pump is working depending on the make of boiler, check under the boiler make sure the 2 22mm valves are open (facing towards the front of the boiler) and really stupid question are the rad valves open?

thanks for the reply crashndie.i will double check the valves.the hot water is another saga !someone has added an electric boiler.there seems to be a rad bypass valve arrangement on the rads.the boiler fires up and then the pump will run all day but pipes not getting hot?
