Daikin Altherma ASHP technical specs
Posted by: @bm212It would be great if there was a non-destructive way of figuring out what the pipe sizes are...
physics says that if you know what flow rate the existing circulation pump is running at, its power level, and the characteristic curve of the pump (which is part of the mfr spec), you can then infer the head loss of the system. That known head loss at known flow rate then allows calculations about what head loss will be expected at the flow rate needed for an ASHP, and whether is within normal bounds for an upgraded circulation pump and other components, and whether it can be made to work or not.
you need to get hold of a good heating engineer to do this for you, additional equipment will be need to be fitted to measure all this on a "typical boiler" system, there is testing and maths, it will not be free.
But if its worth it to do that versus lifting floors then it may be an option.
