I have an old 100 Gallon boiler that heats my house. To say the least it is less than efficient and I am looking to save some money on gas this year. I have taken the insulation in my attic from a R almost nothing to an R39. I was wondering if it would be effective and safe to put 2 (because it is so large) water heater blankets around it. Although I do appreciate opinions I would like to hear from some pros who have an experienced answer.
If the heater is designed for a blanket it may help a tiny bit on your bill to wrap it. You must examine the heater and make the decision if it is safe to do so. With the age and design of the boiler the insulation may be a waste of time though. On these old systems it may be a case of complete replacement to get any significant savings in the end.
