Makes little difference.
the mini had a tap. You want hot air open it and hot water flowed into the heater.
the metro had continuous flow of hot water but had flaps in the heater unit to bypass the air flow from the heater for cool air.
the MPi was slightly different in that it was like the mini in that you had to open a tap to let the hot water into the heater but when the tap was closed the water continued to flow but directly into the bottom hose.
Oh yup awesome. So ill just use an always open bypass so its always flowing. then just open the heater valve when needed. the heater comes with a T branch so that should work.
what do you think of the heater from Aliexpress below. It will be hidden away so you wont see it. i will have 4 front vents and 2 demister fronts similar to the david brown remastered mini interior. Do you think this will provide enough airflow?
Ill be connecting motorised dampers to each heater outlet port which will enable me to switch between either front vent or demister functions.
