We have a 4400 wood master outside stove0

It is a single family house it occurs in the kitchen sink and in the bathroom also so whole house0
-
So it is a tankless coil?0
-
No coil just a tank it's an outdoor wood furance tied into hot water baseboard in the house0

Maybe you need more wood ... Normally the hot water and boiler water is seperated. If there is only one unit your hot water is heated though a tankless coil .

Hi @JW2023 , Have you checked for a crossover in the piping? Is there a tempering valve that's scaled up? I'd like to see a photo of the wood furnace piping connections and surrounding piping... By the way, checking for a crossover is pretty easy. Just shut off the cold supply to your heater and open a hot tap. It should stop running in seconds. If it doesn't, cold water is getting in someplace.
Yours, Larry0 -
