If you’re using a tankless water heater for both space and water heating, however, I think the payback would be more favorable. I wonder if the research team has any plans to look at that system.

This is not to say that heat pumps aren’t a good economecal solution to water heating because they are

Typically a tankless system will be only suitable for small amounts of water, certainly not taking a bath, it takes ages to fill and the fuel consumption is significantly more than a in tank heater system. Overall the energy and cost requirements are not what they claim to be dependant on the fuel type.
In my fieldd tests the combination of linking and ground source pump, through a surface black mass (either at ground or roof based) increases efficiency expontentially.
One other way which is marginally contentious is to use ground source cooling. The reson being by directly connecting the ground temp to the structures internal air temp a building can be held at 10 degrees C all year round by using a single 100w pump, then by swithching the room light on, a 100w bulb will heat the air temp to a comfortable social levell around 74F within minutes. However ir the building envelope has little thermal mass, cooling fights heating and energy costs increase.
Ignore solar gain as it is like science, yes it can be calculated but usually the calcs do not bear a relationship to reality…
