Further to @Temp's reply in @joe90's topic Can we keep the lights on this winter? Our ASHP has it's own main electric meter with nothing else connected. Testing over hours, it appears that my previous estimation of the standby power consumption is about right. The results for our ASHP on standby is a rate of about 82-84 watts, so total used for 24 hour standby is 1.968-2.016kWh assuming no power used for the heat protection of the ASHP. This was measured with an outside temperature no lower than 8.8C over the last 24 hours and no lower than 9.9C during the period of measurement. Bearing in mind that the ASHP compressor must be warm enough to work without causing excessive wear, and requires 12 hours of standby after the outside temp achieved rises above 5C, this may mean that we cannot turn the ASHP back on for 12 hours after a power cut! I hope every ASHP owner with the same compressor requirement is aware of the dilemma of either having no heating for 12 hours or risking excessive wear of the compressor. Marvin -
Does one of our experts know whether Solar PV panels generate electricity for the house during a power cut? AFAICS there are a few relevant issues: 1 - Grid connected panels are presumably auto-disconnected to avoid feeding power to the staff doing repairs. 2 - Is this different depending on whether it is a grid-connected setup or a self-done standalone? I expect it depends on what is disconnected and how. Any comments are most welcome. Ferdinand

Probably like us you have had a power cut or two over the past couple of weeks - what fun. This set me wondering because in 3 weeks we will go over to a full fibre connection to Millstone manor and our land line will switch to Voice over Internet protocol (VOIP). With the traditional land line the power for the phone - ringing and speech is derived from the exchange so they stay working in a power cut. What happens to your VOIP phone in a power cut at you home I wonder, I assume it stops operating, and then what happens to your monitored alarm if the power fails because it can no longer warn you if you are out or inform the monitoring company if an alarm is triggered. Just solved the alarm problem by getting our alarm company to switch us to radio monitoring, but what about home security and emergency calls. Do I need a Uninterruptible Power Supply (UPS) I wonder and if so how big.
