Upstairs Colder than Downstairs
I have been reading many posts on these walls and tweaking my steam system, but my problem remains: My upstairs floors is approx. 4 degrees cooler than downstairs. Let me give you some background on what I have done so far to improve my steam system:
1. my steam boiler is brand new, and I have had it confirmed that it has been set up correctly (i.e. pressure setting, piping, etc. is correct).
2. I have replaced all the vents on my radiators with Varivalve Quick Vents
2. I have wrapped insulation around all my pipes in the basement.
3. Lastly, I have added two Groton #2 at the end of both my main pipes to make sure that venting is quick.
Based on all the above tweaks, my system works quite well. Once the boiler fires on, within 10 minutes approx. half my radiators get warm, and after another 10 minutes (i.e. 20 minutes in total) all radiators are nice and warm, and the house heats up quickly and fairly evenly. Is this response time good?
The problem is this: Let's say I want upstairs to be a comfortable 72 degrees at all times. To achieve this I initially set the thermostat (that is located downstairs) at say 74 degrees. The house quickly heats up, and soon the heat shuts off and the desired temperature are met upstairs and downstairs. However, this is where the problem slowly sets in. With the downstairs thermostat set at a steady 74, gradually the upstairs temp starts dropping. Within a day or so, it falls to 70, and I am back to my original 4 degree differential. I dont want to turn downstairs any higher than 74, but 70 upstairs is a little to cool for comfort.
I have tried to analyze what is going on, and my only possible explanation is that my heating cycle is too short. on average, my boiler fires up approx. every 90 minutes, and it stays on for 10 to 15 minutes each time. it seems that this is long enough to heat downstairs, but not long enough to heat upstairs properly. Is my thermostat at fault? I have a Honeywell Pro TH4000.
These are all the relevant facts I can think of. Does anyone have any suggestions?
