Hello. I've just had a brand new ideal heat 24 system boiler fitted. Today been told by aNother heating engineer and looking at discussions on the Internet. There seems to be a problem with this particular model with the plastic sumps cracking. I've contacted idea. And they are denying that there's is /was any problems with there sumps slitting. Does anyone know if they have addresses the problem with inferior parts or have they produced an uprated version to over come this issue. Mines a new 2019 ideal heat 24. Hopefully this has got a better designed or stronger sump
