My 3 RES have been in their new home for a day now, I do have a water heater I have never used but my QuietOne 9000 return pump has brought the water temp up to 77.9F.
I have used a digi probe thermometer and it says the min was 77.2 and max 77.9 in the past 24 hours.
I just recieved a therm gun in the mail today and it confirms the digi probe as acurate.
1. My RES are 2 yrs old and about 6", is this temp ok?
2. When it isnt 70F outside my house will be much colder, more like 65 with house-heat on. Would a corresponding drop of a few degrees be acceptable?
