I'm finally getting the materials to hook up my dhw. I do have a few questions. My boiler has the dhw coil that goes into the back of the stove with two hookups (water going and water coming back in).
I will need to use a pump as my electric water heater is 40 feet away from my boiler. I will be using pex to travel this distance and it will be under the house.
My questions relate to the aquastat and pump
Where and how should the aquastat be used. I know the aquastat will be wired to the pump and tell the pump when to turn on and off but I am confused on when and where. Should it be near the boiler and once the boiler water reaches a set degree it kicks the pump on to circulate (and stays on as long as it is above the set degree) and vice versa if the water at the boiler is not hot it keeps pump off? Or should it be near the (turned off) electric water heater and set that so when the water temp gets low (say 100 Deg) it kicks the pump on?
Also I'm guessing the pex will need to be insulated and do folks use the foam pipe sleeves like used on copper
