Sorry not been posting recently, but we have been a bit busy and we do not yet have a phone line in the house. Tomorrow that will change hopefully. Eircom expected to put line in (just as they go into examinership!!).
The weather here has been wonderful, up to 19 degrees with full sunshine for the past few days. This has led to the solar panels working well and getting a full tank of hot water (over 60 deg C for the full 400 litres). Immersion has been turned off now and the energy usage of the house has dropped. We have an energy monitor attached to the live feed into the meter. The base load of the house seems to be around 100W which includes for the heat recovery system as well as the fridge freezer and any appliances we have forgotten to turn off! The main users of energy are now the appliances for cooking & washing / dishwasher.
The sunshine has also heated the house up considerably, with no shading from the trees (no leaves yet) and the lower position of the sun, this has increased the solar gain. The temperature gets up to 24 deg inside. Opening the door or closing blinds / curtains helps and the feel of the house is of a hot summer day. As the leaves on the trees grow and the higher angle of the sun reflects more heat away from the glazing this potential overheating should abate. No complaints though, it is Ireland not the South of Spain!
Will fill in the gaps as we go along.
