Review on Cylindrical heater AQUAEL AQN PLATINIUM HEATER 200W (130-200 l) 200 W by Janis Gailitis ᠌

There are two such heaters available for 200 W and 300 W. After purchase and installation, I was very pleased. I bought it, unpacked it, installed it on the water flow, set the temperature and that's it. Very clear temperature support (no more than 0.5 degrees). About three months later, on one "beautiful day", in the morning I noticed that my sprats were wrapped in a blanket, put on hats and mittens and were going to go into the forest for firewood. I ask them what you thought there, it’s cold outside in winter! And they tell me: we’re freezing anyway, we have no more strength, we’ll go for firewood and build a fire, we’ll warm ourselves :)))))) Look at the thermometer and there they have 20 degrees instead of the prescribed 30 ! Well, I think electronics, well, it happens, a failure, well, once it doesn’t mean anything. And nothing of the kind! So both heaters began to stick! They do not react at all to a change in the external temperature (from the word in general!) Until you increase or decrease the set temperature with the button. What is the reason I don’t understand, I don’t want to delve into the operation of the device, I need to turn it on and forget it.
