While I have not used the same branded ovens with and without modulating gas valves, when I switched from my XLT’s w/o modulating valves to the Edge ovens with modulating valves I saw a significant decrease in gas usage. As a bonus the “roar” of the burners when firing is silenced to barely a purr with the modulating valves.I acquired a nice pair of 2007 MM PS360WBs with modulating gas valves
it is worth my time to swap them out with my older 1991 PS360WBs that have regular valves? any real savings or benefits in this? as its a fair amount of work
Thanks guys
