So, what does the OP do for next year?
Should he sell the Kaa-2 and buy the larger Kaa-4 or better yet, the KA-6. This board has taught me that size matters, and you can never have enough btu's. I would rather complain about unburned coal in the ash pan from an idling boiler than be in a situation where the house is cold because the 5 or 6 thousand dollar boiler I bought is too small.
Just posting an opinion.....
A great question, for people who already have an existing boiler/heating device.
Reading through several heating forums, I've come across multiple topics where this issue is discussed. Design temperatures, for the most part, only take place a very small percentage of the time. So the boiler/heating device will only run at design once a season or so (more, if global cooling is actually happening). In fact, over the last three years, at least in this area (Philly burbs) this is the first time we've been at design temperatures.
And I'll add to Windy, better to insulate the house and put on a hoodie when it gets real cold, then worry about a week in the winter when it will be 66 in the house instead of 72.
Again, that's only for the folks caught in this situation that have an existing boiler/heating device that have found out that they are maxed out in this weather.
