tank temp with out a heater

[sphelps]

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.
