Men,

I have just opened up the fireplace in my living room and had a cast iron fireplace fitted. In the kitchen I've also installed a Tiger multifuel stove.
Is it possible to fit a back boiler to either or both of these to make the most of the heat provided and if so approx how much would it cost.
The multifuel stove is almost directly below the hot water tank in the airing cupboard so pipework could be quite minimal.

Thanks

Gammy
