Re: [Distillers] Re: boiler insulation
- I have to agree...converted my Water Heater in appx 10 minutes...my 14 year
old son could have done it as well....probably 7 minutes or
less...:>)...maybe its too simple for 'great minds' to grasp......read
somewhere that Einstein(sp?) couldnt recall phone numbers....:>)
