HONE can be deployed in large industrial projects especially where there is no existing energy infrastructure. One major advantage of HONE is that the technology stands on its own so a large plant could be installed in Africa where there is no existing energy supply. HONE can provide hot water, cooling and electricity from one plant.
Imagine, it is raining heavily and you have your under floor heating running and then the sun comes out and starts shining in the windows of your nice new house, the temperature will climb rapidly and you won't be able to stop your heating system for 4 hours and all that energy will make your home very uncomfortable for several hours. By using radiators, you can turn your heat on instantly and turn it off instantly; thus using the correct amount of energy and keeping your home at the right temperature. This is worth considering especially if your building has lots of glazing.
Using radiators in a modern A3 or better means only a few slim radiators are needed, typically only 6 in a 2,000 sq ft home and not under any window so your walls are clear. The design considerations have all changed.
