Heatpumps For Everyone

See if you can speak to someone who works with traditional buildings and natural materials, there could well be an external insulation solution which benefits the fabric of the house, it's less likely to cause damp problems and less disruptive than internal insulation. If you can keep your home more warm and dry it'll be much more comfortable let alone saving energy.

Edit: Material suppliers might be able to recommend builders/architects etc in your area (try Unity Lime, Back to Earth, Ecological building systems etc)

Ah, yeah the integration with ToU tariffs does sound appealing.

May I ask what your SCoP thus far has been, and average yearly ASHP consumption?

The SCoP reported by Homely is far too good, the one I calculate from the Samsung controller is quite shit, so I’ve decided I don’t care too much.

The ToU tariff means we may be running the HP at inefficient times (middle of the night when its coldest) but in the bigger picture this is better for the world as we’re shifting our usage out of peak times and soaking up surplus on the grid. I think.

Thus was somewhat my intention, rather than rolling back at night, making the most of cheaper electric to boost the heat for the morning and then trying to ride that and roll back during peak hours.

From looking at the pricing graphs, as long as you avoid 17:00-20:00 you're grand.

We just leave ours set to Xdeg 24/7 as reclaiming to lost temp seemed to cost more in the long run then it saved. This is only looking at the energy in vs energy out graph, I included the unit price difference, but I could be wrong.
