i thought it to be a bit of overkill, but will use it for bulk cooling.

i needed a unit to build into a cogenerator, ie heat and power. my target was 2 one hour runs per day.

i became concerned with the bulk charge rate needed to bring back up the planned battery bank, when upon reevaluating the need the battery bank became smaller.
that is when the problem with having too large a unit to deliver far more charge rate than i needed. most especially during spring and fall, when either the heat generated would not be needed or the cooling capacity as well not needed.

that is when i started thinking of a unit sized more in line to the needs of the sping and fall months.

quite frankly as cogenerators the 12 hp unit should be pretty close to filling the bill during the heavy heating and cooling months as a cogenerator, and the 6 hp unit should work well during the spring and fall as a cogenerator or electricity and domestic hot water.

these units as cogenerators more closely fit the need projected.

i am going to go ahead and install the thermoking for those times when in the summer i get home and it is over 100 degree's and want a fast cool down. or in the winter when i need a fast warm up. This is where the thermoking really kicks butt, that is mass btu's
