    hey guys! quick question, if I buy one of these heaters and the capacity is to big, is there a way to reduce the amount of water that gets heated in it?

    It would depend upon the make & model whether or not it can be range rates or not.
    Generally, they heat the water to the set water temperature & maintain that temperature. They are generally incorrectly under-sized & cannot keep up with the demand of many draw off points opened at once rather than being over-sized.

    You should never reduce the flow of hot water by using the inlet stop cock, most water heaters have a built in water temperature selector that allows you to throttle the water supply up or down within its minimum and max range.

    look to the manual for max and min flow rates, the new ones normally can modulate down pretty low (it's usually people have a problem with not enough hot water!)

    Rinnai water heaters are magic IMHO
