Saving energy

In domestic houses, the energy usage pattern is space  heating and hot water generation still take up the lion’s share, yet most houses are still fitted with crude, energy-wasting timeclocks and thermostats. With a potential energy savings of 25-30% by fitting better controls, this has to be an area worth exploring. We can save money, CO2 emissions, and be more comfortable - surely it’s a no-brainer!

How can savings of this magnitude be possible? As is often the case, the principles are very simple, but the detailed implementation is a little more involved. Basically, we need to ensure that heating systems are only running when they need to be so that we are not heating parts of the house unnecessarily, and that when running, the rooms are heated to the correct temperature - no more, no less.
