Indirect vs Storage HW Tanks
I have talked to 4-5 professionals in the heating business. Three oil companies that install Boilers and tanks and two so-called energy companies who don't sell oil but design and install systems.
I have quite a mixed bag of opinions although the majority favor indirect, two of the guys said the storage tank is the way to go. One each from oil company and one energy company
By storage I mean a tank getting hot water from tankless coil and storing it with a re-circulation pump if temps drop.
I understand the operational theory of both but why the large difference of opinion? Interested in how two professionals from the same type of business model can come to such widely differing conclusions.
I currently have a tankless ONLY system and it will soon be gone. Boiler being replaced.
