Greetings! Few weeks ago, I had installed my Irleh Plus 40kw gasification boiler. The problem is that it takes long time to heat up to 85 degrees Celsius, and we need to refuel every 3-4 hours, which I find a very short time. There is also a 1500L puffer installed. After I manage to raise the puffer up to ~80 degrees Celsius, it cools down to 30 degrees Celsius until the morning (As far as I know, it should keep the high temperature up to 3 days). Thanks in advance for the advice!

I am from Romania, and winter is far away to be over... Please help us, we are running low on wood supply!
