I would greatly value an opinion on the merits/need of water storage. Our monastery will be installing a wood gasifier to heat our hydronic radiant floors, and have been looking most seriously at EKO and the Econoburn. The importer for the EKO very kindly explained why a storage tank was so valuable, and it made great sense to me. The people at Econoburn kindly explained why a storage tank wasn't needed really, and that also seemed reasonable. Is the technology that different between the two boilers or is something else at play here? Many thanks for the help.
