Calorifier to stove backboiler

[The Lame Goat]

I have a Surecal dual coil calorifer with one coil connected to my engine, and the other blanked off. I also have two radiators connected to the back boiler of my coalbrookdale duel fuel stove - this is gravity fed.

 

My question is whether to use the spare coil and hook it up to the boiler feed, and if so how. I suspect gravity won't work its magic throug the calorifier...

 

...so I envisage taking a loop from the hot side of the last radiator through a pump through the calorifier and back to the cold side of the last radiator.

 

Has anyone done anything like this - if so, what and how?

 

Anyone got any comments on my scheme or better ideas?

 

I don't mind the last radiator losing some heat when the pump is running, and I'll only run it when I want to heat up the calorifier anyway. But might there be any issues with the boiler when a pump is attached, as obviously this will increase the flow?

 

Thanks,

 

Mark

From a purely plumbing/engineering point of view this seems perfectly doable.

Could do but it might be a bit better to tee in the pumped circuit close to the backboiler, otherwise the some of the pumped flow through the calorifer may bypass through the radiators.

 

cheers, Pete.
