For 200 gallons, I started with the hot water from our 50-gallon tank,
using an adapter on the kitchen sink and garden hoses running out 100
feet to the brewer sitting in an unheated pump house. The hot water
tank was set at 120 degrees but reached the brewer at 100 degrees. The
hot water tank drained (which is a good thing to do periodically for
tank maintenance) and fresh water coming in to the tank from the well
pump had a chance to warm slightly before running out again to the
brewer. Of course the flow from the tank was decreased at this point,
but with other hoses from the house's cold water spigot to the brewer,
the temperature of the water in the brewer was at 80 degrees. It took
about 2 hours to fill the brewer. I kept a small heater on in the pump
house and the air temperature was 72 degrees and the brew stayed about
the same. This is Bob's Brewer; the one Bob Norsen graciously donated
to our fruit club. We had our first batch of tea this weekend. The tea
looked and smelled great. The fruit club members drove up with their
quart containers, gallon jugs, and some with 5-gallon buckets. The
compost tea was gone in two hours. We'll do this again next weekend.

Hi Jason You and others might do better to start with an efficient 80
gallon hot water heater that puts and holds all the heat in the water
rather than in the surroundings. Then fill your tank 80 gallons short
of full with typical 52 F well water. Add 80 gallons of 160 degree hot
water and you are going to be at 70 degrees right away and ready to
start the brew. No 2 day wait for the water to heat while the brewer
tank loses about half the heat you are adding. A gas fueled HWH would
be economical. compared to electric if you can use gas.
 
Heat loss in the 24 hour brew will be partly offset by microbic heating.
An air driven brewer will cool some. good in summer. Can be offset in
winter with in-tank heater. External heaters are gong to put some heat
in the tank and some into the surroundings. Not very effective.
Defroster cable used to de-ice roof edges can be used by closing the
thermostat.
 
It won't take much heat to keep the system warm. Bob.
