Reliability and durability - that's about it Compact size, especially noticeable in a small 1-bedroom apartment. Heats up quickly: not sure if it's due to the special tank design or a good heating element, but you don't have to wait several hours to get hot water. When heating, it is surprisingly quiet. Compared to cheaper alternatives that howl and whistle, this one is simply silent. Energy consumption: thanks to the rapid heating and good tank insulation, the boiler maintains the temperature for a long time and does not turn on frequently, which saves on the currently "golden" kilowatts in the utility bill. Installation is simple and can be done without experience with minimal tools, as the appliance is not heavy—no need for specific fasteners. I would also like to note the good package and instructions. For more than 3 years, without giving in to the negativity, I hope that at least as much as possible we will continue to serve.

I have my own watch repair workshop, and clean hands are as essential in the watch business as they are in medicine. In the summer, cold water is fine for this, but because the plumbing pipes are not deeply buried, in the winter, the cold water turns icy. Perhaps in my youth, I wouldn't have paid attention to such details, but when you're in your fifties, you really don't want to freeze your limbs under icy water. That's why this water heater was very timely. My son installed it, he's quite handy, and it took just over an hour for everything. Besides washing hands, I use the hot water for cleaning and initially degreasing parts (the secondary degreasing is done in alcohol). Overall, I'm satisfied with the boiler's performance and have no major complaints. Rapid water heating. This is perhaps the fastest of the storage water heaters that are on our market. I specially measured it - in the heating mode to the maximum temperature, it copes with the task in 12-13 minutes. In winter, when the water freezes, the process is delayed up to 15 minutes. Management is simple and convenient, it consists of exactly one regulator Excellent price. By now, this is a very good option, much cheaper than most competitors. Nice appearance. Made in the EU. I have never been able to find a compact water heater with a thermometer. Even though it would not be too accurate and show approximate values, but I want me to SEE the temperature of the water, and not try to try it with my hand. |
I was choosing a small electric water heater for the country house and bought this model. This European product of Bulgarian origin impressed me with its simplicity and elegance. I installed it myself, choosing a spot to the right and below the sink. Looking at it, it's hard to believe it's a full-fledged boiler. It seems unreal, like a toy. But that's not the case; beneath its plastic housing lies a real steel storage tank coated with a special protective enamel and equipped with the mandatory magnesium anode for all steel boilers. The cold-rolled sheet from which the tank is made must be thick; otherwise, it wouldn't weigh 7kg without water. It heats water quickly, bringing 10 liters to almost boiling in 35 minutes. The heating element has a power of 1500W, which isn't a record, but it doesn't overly burden the electric network. The design is minimalist, with nothing unnecessary—just smooth, rounded forms. Its compact size takes up minimal space when installed. It comes with a two-year warranty on the heating part and a five-year warranty on the storage tank. Made in Bulgaria. Designed for installation under the sink, but lacks splash protection. An absurd combination. The included safety valve was leaking and had to be replaced. If the boiler maintenance is performed by an unauthorized specialist, the water heater warranty is voided. There is no indicator or display to check the water temperature in the tank. |
