The issue of energy efficiency is being looked at on a number of levels, from how nationwide energy grids operate, to those of individual homeowners who are trying to reduce their consumption, and their energy bills.
To speak to the latter, take a look at this video that talks about how one homeowner is using radiant heating and cooling to manage interior temperatures in his home in Oregon. The system he talks about controls his hot water, as well as the temperature of the interior through a smart hot water heater, radiators, and an under-floor pipe system. Use of the system results in no heat loss.
A good point made in this video is about the proximity of the kitchen to the water heating system. The kitchen is where a good deal of water use is central. I imagine that the bathroom is close by as well. When the hot water heater is located far away from those places by design, the ability to manage energy efficiency is that much more challenging. This therefore has something to say about how the layout and design of a home has an impact on how potentially energy efficient it can be.
Does anyone out there have a similar system in place? What are your experiences? Any sceptics out there?
