I am looking at adding a gassifier and storage to my home. I am heating around 4,000sf-all radiant. I built it 18 months ago and have a triangle tube propane boiler and a new yorker wc-130 add on boiler which I hate. I am getting rid of the new yorker. I wish I would have found this site before I built! I have a 17x14 cistern(township made me put it in) that is next to my basement and would easily be connected to my boiler room. I was thinking of converting that room into a room for storage tanks and to store wood. Questions are: does anyone have experience with the varmenbaronen vedolux 37? would the effecta, which is $2600 more, be worth it for the added sensors and controls? I would have room for 2 1,000 gallon tanks. With the weight of them filled (over 10,000lbs) it is impossible to stack them. Also is it feasible to use and indirect water heater with storage? And if so, what is the minimum temp that is still efficient? Any input would be greatly appreciated.
