You know we have kept the Auto-del. contract because we get sonic testing for our oil tank, and only pay $125 per annum for a service contract. but these people won`t deliver when it is an affordable bill. just dipped our tank, (not filled last year) and I can see when they fill it, it will be 600 litres-or cost with taxes about $750. Now, I just know they are going to wait till next June to fill it. Well, surprise, surprise. I just shut it off. I know I`m a bit slow, but finally figuraed out that using the (wood insert) on the first level and the propane insert on the 3RD level works out to be zone heating" cheaper and much more comfortable." And before you guys jump all over me for not heating entirely with wood. Well, I wanted a stove on the 3rd level, but the better half doesn`t like the dust and crap that goes with it . You can go on other forums and they will explain that oil gives you better bucks for the BTU vallue. Except when it comes to "zone heating" and in our case -wood and propane combined are much better value..Anyone else get pissed off, about the oil companies waiting for maximum profit before they come to fill your tank? Wood heat, and more wood heat. and my propane insert for the booster effect, and that`s it. No more damn oil , --and ya know that when I kick in the propane insert on the 3rd level to get the temp up to 72f, only takes about an hour and a half, then the wood heat will maintane it for the most part. Has taking me a long time to learn this , but seems like zone heating is the way to go.
