He offered this calculator, link at bottom, in a tweet. Basically showing compatibility for a HP in various areas.

4 examples for locations of frequent posters.

The temperature data itself is helpful for determining have you might vary SWT on a hydronic system with properly tuned ODR.

Also this tekmar essay 003 explains the various way to fine tune an ODR based on the type of heat emitters.

With a mod con replacing a conventional boiler on a system requiring 180 SWT at design day, you can determine how often, in hours per year, the boiler could possibly operate in condensing, high efficiency mode.

In Idronics 25 we show how reducing required SWT with building upgrades and then applying ODR based on the lower loads can leverage a condensing boiler, reducing fuel conception and possible comfort increase.

The example used in Idronics 25 used Syracuse BIN data and shows a load of 100,000 BTU reduced to 70,000 via various building energy upgrades. The energy upgrades potentials can be determined with blower door and IR scans, for example.

This reduced heat load, reduced the required design SWT from 180 to 147°. Fig 3.3
