Small-sized and efficient storage electric water heater with a capacity of 15 liters in a stylish case. It is positioned as a product of the middle price category from the Tesy Compact family, focused on use as part of low-capacity hot water systems. Able to serve the kitchen, workshop, massage or medical office. It is intended for wall vertical mounting with a top supply of communications (installation under the sink).
Due to its shallow depth (only 30 cm) it can be installed in rooms with a limited area. Able to quickly, in just 27 minutes, prepare 15 liters of hot water at a temperature of 60 ° C (at an initial water temperature of 15 ° C). The design of the Tesy GCU 1520 water heater is based on a reliable inner tank with a thick steel wall that can withstand pressures up to 8 bar. The inner surface of this tank is protected from contact with water by a two-layer glass-ceramic enamel coating with increased resistance to temperature extremes. For additional protection of the steel wall of the inner tank against corrosion, an electrochemical tread system with a magnesium anode is provided. An impressively high rate of water heating is provided by a traditional 2000 W electric tubular immersion heater, which is controlled by a trouble-free capillary thermostat.
Always clarify the specifications and configuration of the product with the online store manager before purchasing.

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.  Aleksandr Ch: use Tesy GCU 1015 more than year |
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. |

Reliable Heater
The storage water heater from the brand Tesy is part of a series of small-capacity models with a tank volume of 15 liters. Thanks to the compact dimensions of the body measuring 40x38x30 cm, the device easily fits into narrow spaces, including cabinets under the sink—the upper pipe connection makes such installation particularly convenient.
The key advantage of the Tesy GCU 1520 is the Crystal Tech (glass-ceramic) tank coating, which provides enhanced protection against corrosion and contributes to extending the boiler's lifespan. The design also includes a magnesium anode that protects against oxidation and scale formation. The extended 5-year warranty on the tank from the manufacturer is an additional confirmation of reliability.
Hot Water Without Overpayments
The water heater is equipped with a "wet" heating element with a power of 2000 W, ensuring quick heating. It takes about 30 minutes to reach a temperature of 60°C with an initial water temperature of 15 degrees. However, for basic tasks like handwashing or dishwashing, it's enough to wait just 10–15 minutes. The heating temperature is adjustable with a rotary switch, and the operation of the heating element is indicated by an LED indicator.
The model features a moderate level of energy consumption and belongs to class B, making the Tesy GCU 1520 a reliable and relatively economical solution in the mid-price segment, ideally suitable for under-sink placement.
