Hello Folks,
I have recently joined Hearth. Have been reading posts for some time now and decided to join.
I appreciate the wealth of information here.
This is my first post.
I have installed an EKO 40 and am in the process of adding open storage to the system and a controller, {still needed}.
We had an old 2000gal. oil tank which was underground and has been removed from service.
I Cut the tank, sand blasted it, welded all the bullet holes, painted it with 2 part epoxy paint.
Welded 6 tank taps along the top for connects.
I made up two heat exchangers, one for space heat/solar and the second for DHW. Its going to hold about 1150 gals.
Still have to finish the final connections and insulate the tank. See picts below.
The EKO 40 is located in the attached garage and the Oil boiler is in the basement of the house with all the zone circulators and
a radiant manifold for heated floors in specific areas.
I modeled the storage design from information I found from http://www.stsscoinc.com.
But first I was wondering if someone with more experience than myself could review my diagram and tell me if the following
makes sense:
Four way piping
Wood & Solar to House
Wood & Solar to Tank
Storage to House/DHW
Wood & Solar to DHW
WHAT HAPPENS WHEN YOU FIRE THE WOOD BOILER
Refer to Plumbing Diagram.
If the wood boiler is operating when the house is calling for heat, both the C-1 and C-3 circulators move heat
directly to the zone(s) in the house calling for heat. When both C-1 and C-3 circulators are pumping, heated
water by-passes the heat exchangers in the tank.
If the wood boiler is not fired, C-1 circulator and the Zv-l valve begin moving heated water from the top of the
tank heat exchanger to the house. Water travels bottom to top of the tank heat exchanger coils when removing
heat from the tank. Water travels top to bottom of the tank heat exchanger when the wood boiler is heating the
tank.
When circulator C-3 is operating by itself, heat is transferred to the tank. When C-1 is operating by itself, heat
is transferred from the tank to the house.
Two flow check valves placed in the same pipe, but in opposite directions (refer to the piping diagram
for this layout ), maintain a perfect balance between the flow of water from the boiler to the house regardless
of how many zones are calling at the time. Without these flow check valves there would be a constant
bleed-off of heat to the tank, even when all zones are calling at the same time.
Please note the following diagram

Thanks for any help,
