Hi there.
I have just moved into a property that has a Ferroli Optima 701 boiler. I am not sure whether there is something not right with the central heating hot water supply from the boiler.
The DHW is red hot, almost scalding. I cannot hold my hand on the outflow pipe on the DHW.
The CH outflow pipe is warmish and the radiators never get what I call that hot. While the CH is being demanded, the main burner is lit constantly and is not going on and off.
The DHW is fed by a 15mm pipe and the CH is fed by a 22mm pipe
Could it be the larger pipe size and hence a faster flow rate that is causing the CH not to get hot ?
Any advice would be greatly appreciated.
Thanks
Chris Brennan
