When I did some renovation work in the house last year, I cut out a radiator & never restored any of the oil fired heating loops. I figure the only way I’ll get around to it is if I ever have to sell. Right now I’m running my DHW system off an outboard fuel tank running #2 connected right to the burner pump, primer bulb and all 
– I can't get myself to pay the $money$ to get the main tanks filled. I already bought my season's coal though.
