I run a similar tank to the one mentioned earlier -- same thing as well -- no heater no chiller.
Im a 220, with about 50 gal sump. My house is about 74F all day long, and I have an HRV as well. I had the same thing where the heater just never kicked it. A fair amount of heat comes from the pumps, and I think this is what is happening: Some heat comes from the pumps, and extra is from the lights -- during the day the extra heat is controlled through evaporation (fan blowing across the lights) and low humidity where I live allows a lot of evaporative cooling. As everything is well closed up, the whole tank holds a LOT of heat, so it is a slow rise (1-2 degrees) over the day, and a slow cool down just because of the tank volume. Hence, no heat or cooling needed. Once upon a time I left for a weekend and my A/C didn't run. Came back to the tank at about 85 -- and it took 4 days after the A/C was running for the tank to cool down. Quote:

Pretty interesting to hear of people not using heaters, I guess if you keep the house consistantly warmer at around 74 as stated there really isn't much need for a heater. Perosnally I think you guys might save some money by keeping your house cooler in the winter and using a heater in the tank. Our house is pretty well controlled as well but in the winter the house temp drops to 16C over night which is pretty typical for people with programmable thermostats. Heating the tank as appose to the whole house makes more sense to me.
