Good Evening Fellas,
I just looked at an outdoor wood boiler piggybacked through a plate exchanger to an older (30 years give or take a decade) steam boiler that's only used for forced hot water currently. The complaint is the wood boiler is not keeping up with the domestic hot water. All the heat zones go through two tankless coils and the DHW comes off the bottom of the steam boiler. I think the tankless coils are scaled (sp?) or rusted up and the heat from the outside boiler is not heating the water in the steam boiler enough. Either that or the four other zones are using too much heat first. My thought is to add another plate exchanger solely for DHW and reconfigure the other zones to hopefull bypass or replace the old steam unit. Any thoughts or comments would be appreciated.

Contacted Central Boiler and they suggest abandoning the old steam job and adding a larger heat exchanger into the mix. However the Home Owner still wants an oil backup in case they go away or run out of wood. Thanks for the site though.
