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.

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.

Toy-looking, but quite powerful and efficient
23 May 2016 
I chose a small electric water heater for a country house and purchased this model. This European of Bulgarian origin won me over with his simplicity and elegance. I installed it myself, I chose the place to the right and down from the sink.
You look at it and you can’t really believe that this is a full-fledged boiler. It seems that he is not real, a toy. But nothing like that, under the plastic case, inside there is a real steel storage tank, covered with a special protective enamel, and a magnesium anode, which is mandatory for all steel boilers. The cold-rolled sheet from which the tank is made must be thick, otherwise it would not weigh 7kg without water. It warms the water quickly, brings 10 liters in 35 minutes to a state of almost boiling water. The heating element has a power of 1500W, which is not a record, but it does not load the electrical network too much. Minimalist design, nothing superfluous, just smooth rounded shapes. Compact size, takes up minimal space during installation. Two-year warranty for the heating part and five-year warranty for the storage tank. Made in Bulgaria.
Designed for installation under the sink, but does not have splash protection. An absurd combination. The complete safety valve was leaking and had to be replaced. If the boiler maintenance is carried out by an unauthorized specialist, the water heater is voided from the warranty. There is no indicator or screen on which one could see the temperature of the water 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.
