Hello,
I have a small multi fuel stove with a back boiler I am in the process of plumbing up. The main piper work is in which takes me from the fireplace directly upstairs vertically to the cupboard with the thermal store in it.
Our oil boiler heats the rads and thermal store all on one circuit. My idea is to use two none return valves on the feed from the oil boiler and T into the thermal store coil for the gravity circuit after these. The idea being that this will stop flow from the stove into the central heating circuit and only allow it to circulate around the thermal store coil.
Now as I understand I cannot have a non return valve on the gravity circuit so how can I stop the flow from the oil boiler going into the stove or should this just be accepted?
Also I was thinking of installing a 3 way valve with the second feed from the stove going to a small radiator in our bedroom. The idea being that when we go to bed we can load up the stove and turn the valve so the radiator in our bedroom stays warm. The circuit for the radiator will need to be pumped in order to reach the radiator so I wonder would the 3 way valve even be necessary? Could it be that when the thermal store is hot enough the pump kicks in and draws excess heat to the radiator? The pipes for the radiator will need to go up through the attic and down into the room so will the gravity circuit still naturally flow through the coil of the thermal store as the radiator pipes run higher into the attic?
Sorry for all the questions but any help would be excellent. I can plumb in the thermal store circuit for now with no problems. The radiator was just an extra idea.
