We are new to Alde heating and hot water but over the last seven days/nights of very cold weather it has worked well. I have set the system for both night and day so that the MH is cooler whilst we sleep and the temperature rises when the day setting kicks in about an hour before we normally get up. The only problem has been showering in the morning. If we get up well after the van has reached the set interior temperature and the boiler has stopped the hot water will have cooled and there is not enough for two good showers. I have tried the different water priorities setting but even on the highest it is not enough. Does anyone have a tip or trick to get around this anomaly?
