I am working on an EKO40 system with a friend of mine and have a question regarding the size/type of coils required for the pool type storage unit we plan to use.
The facts thus far are as follows:
900 sq. ft. gagage with 11 ft ceilings = 43K BTU required to keep garage at 60 F on a zero degree day (we are planning to purchase a unit heater)
1,512 sq. ft. main level with 8 ft. ceilings = 35K BTU required to keep garage at 70 F on a zero degree day (exisiting baseboard)
1,000 sq. ft finished basement with 8 ft ceilings = 25K BTU required to keep garage at 70 F on a zero degree day (existing baseboard)
Total BTU for house w/ garage is 103K BTU
We are planning to have approx. 1,500 gallons of storage and thus need to determine the qty and size of the coils required to go into the water tank.
I have looked at the STSS web site and reviewed their coils but am not quote sure how to calculate the ones I need.
They have 2 coils shown: 120 ft coils with 26,400 BTU capacity and 180 ft. coils with 39,600 BTU capacity
(both coils are rated with the BTU’s listed above at 120F average tank temp)
However, we plan to keep the water in the tank between 140-180 and thus I’m a little confussed at the BTU rating at these higher temps.
Obviously, on colder days we need to keep the temp hotter and on warmer days we can let it get to 140F.
I’ve contacted STSS but have not heard back yet.
Thanks in advance for your help
