I have a Lanair used oil furrnace,it was the best thing i ever bought,i heat a 30x50 shop with 10 foot ceilings.I burn between 600-800 gallons of oil each year,i ran a bodyshop and dont generate my own oil,i placed an ad on kijiji and i now have a bunch of regular customers that give me the oil for free,all i have to do is go and get it,it does take a bit of work to get it,but here today furnace oil is 1.87 a litre?,if i was buying furnace oil it would cost me between 5 and 7000 dollars,i have too many scottish ancestors to do that.🤑.Lanair makes a smaller heater for "hobby' guys,i definetly recommend them,great company to deal with and the heaters are very reliable. harvey
