On the face of it that would work ok but you would need to check out any safety aspects concerning a pumped only system such as possible flow blockage (sludge) pressure relief and auto boiler shut down if things get hairy, I am not a guru on that as all the systems I have done use the HW tank as the main heat sink ie: our woodburner is on gravity HW, CH is pumped, I have a cross flow boiler so no injector tee needed.
Imersion when no kids is ok and won't break the bank, we use ours mainly in the warmer months when woodburner isn't lit, three quarters of an hour switched on does a bath, half an hour switched on does the dishes or a quick wash.
I like Nicks system, our garden is big enough but underground is now mainly taken up with the drainage field for the septic tank effluent, ground source heat pumps are getting quite popular down here as are domestic solar installations and solar farms, could do with a couple of deep fractured holes in the granite as the temp down there is hot, the air temp down the tin mine I worked down was 30 to 40 c in many places.
