Hello . I am now with my Omi-Latain at the end and hope someone can give me another tip as I finally get it warm. Have the Omega now for two years and it becomes, neither in summer nor in winter really warm. In summer it just gets beyond blue mark. In winter it is always on cold. Have already changed the thermostat and also the heat exchanger, because I thought that is possible. No improvement. Even if I almost complete the cooler with cardboard Zumache arrives in the interior max. lukewarm air. What can I still check/exchange that it finally gets warm ? I am grateful for every tip Gruss Kai
