We had our first snow of the winter followed by a day of brilliant blue skies – both were icy cold. The juxtaposition of these days has, however, created a clear picture of the effectiveness of our air source heat pump central heating.
We were recently asked by Global Energy Systems, the manufactures of our air source heat pump, to fully restart and reboot the system. This is a quick video to show the process.
We hit a milestone on our solar PV system today by producing 5 MWh of electricity since March. This means we’ve saved pumping 1,275kg (almost 1.3 tonnes) of CO2 into the atmosphere.
My personal threshold for when ambient outdoor temperatures start to go cold is 11C. Over the course of its first six months our air source heat pump has not had to work very hard. As we hit October, the average temperature has dropped to around 11C and it’s a good time to evaluate how the pump is performing.
We had afternoon tea at Palé Hall in Wales recently and when we walked around the property we made an interesting discovery; this hotel is powered by its own hydroelectric plant. But what makes the story even more fascinating is this plant was installed in 1920.
When we had our solar PV panels and SolarEdge inverter installed, I thought that the SolarEdge app would simply tell you how much energy we’ve generated (which it does), but it also provides realtime data on self consumption and export, and the app has become a hugely important tool in helping us to understand and evaluate our home energy usage.
