arduino and multiple thermo sensor

philbona:
woodstove is a non interruptible process. I need to spread the hot water following a prioritised route. But when reaching all the thresholds ( heating circuit, buffer tank and sanitary hot water) where can I divert the excess of t°?

You can control the wood stove heat output by controlling the rate it receives oxygen. You can close the dampers to reduce heat and blow in air to increase heat.
