[QUOTE="welshfarming, post: 3397422, member: 44424"] Hi Just wanted to add my thoughts - I've a 75kw boiler and 9000 litre accumulation tank. With very good wood (20% wet) and burning all day about 2 barrowfuls of wood I get the tank to 80 degrees which rapidly depletes to 50degrees overnight on just warming one property. The problem I have found even with a larger installation is that the water is recircing back to the accumulation tank almost immediately, which brings the temperature of the tank down dramatically. At the moment, I am burning wet wood as I've run out now, just haven't been able to get enough cut and seasoned this year, and Im only getting the accumulator tank to 60degrees, which when I switch the heating on at pm INSTANTLY drops to 40 degrees, and then by 11pm its getting cold in the house. The pumping of the cold spent water back into the accumulator tank is the issue, which apparently can be solved by a switch to stop it (that's the latest discussion I need to have with some other biomass company). Basically, Im not sure you want to be going with a bigger boiler or bigger accumulator as in my view the boiler might get the tank up to heat quicker, but the tank still drops in temperature and quickly. That's where Im at at the moment - to be brutal Im so close to spending another 1k and bunging a oil boiler in the system to heat the water when I can't be ar%ed with the wood, it's just too much and takes so much time each day to load the boiler and manage the wood. This summer Im going to ram the shed full of wood and season it, so I wont run out of wood next winter, but I did have at least 10 tons in there for this Winter, which I thought was going to be enough, stupid me.. Or stupid installer who somehow neglected to give me some indication of the amount of wood I was going to need :) If he had I would have run for the hills... [/QUOTE]
