I'm not too long living in an old house which we bought. The radiators are heated by a range in the kitchen and also by oil. The problem with using the oil is that the boiler is in a seperate out house roughly 15feet from the main house and the pipes going to, and coming from it, are old and probably not insulated, therefore most of the heat is being lost through them and the oil is basically going to waste. I cant really check them easily as they're buried under ground.
If i were to dig them up and replace them, Can anybody recomend the best insulated piping to use or is there any other way around this problem??
I'm not a specialist but I'd think soil anyway is as good an insulation as any.
Usually one of the pros is around to answer this kind of question, hope they can help you out.
I've also just learned that there's another type of boiler that i can get called an "outside boiler" which i can position anywhere i like and does not require a chimney because it has one built in. It would save having to replace any piping and hot water having to travel any distance to reach the house as i could position it against the outside wall of the house and run the pipes straight in.
This is something well worth looking into.
