although not in the acs that im taking next week im curious about one thing
1)combi has poor dhw flow hence the gas rate will be lower then the max specifed. in this case would you note the gas rate for the central heating instead?
2)in dhw mode on combi's does it matter if gas rate on dhw mode is lower then specified max? the guy i did my portfolio with said that as long as inlet is correct , that because combi's modulate hot water at various gas rates according to variables like water flow, thermistors/pcb voltage, temp stat, that it doesnt really matter if dhw gas rate is not up to max as long as its operating between mini- and max burner pressures
is he right? many thanks
