so the boiler flow temperature remains relatively low
What about the "response rate" setting ?.
Does turning this up not raise the boiler flow temperature in line with low outside temperatures.
Yes thats my understanding too Balenza. Look at the front panel which is shown on the gotoplumbing.com website. For an outsite temp of 10c (typical of temp at this time of year), a response rate of 1 would give flow of 25c. Turning the response rate to 15 would give 55c. Thats similar to the flow temp I am getting from my weather compensated boiler.
I told my customers to turn the response rate to about 9 and if the house doesn't get warm enough then turn up the response rate slightly and give it a day to see if it improves enough to make it comfortable.
