Model overview based on user reviews
The Tesy GC K51 series, including models like the GCU 1015 K51 and GCU 1515 K51, is praised for its compact size and quick water heating capabilities, making it ideal for kitchens or workshops where space is limited and hot water is needed rapidly. Users appreciate its simple mechanical controls and reliable thermo-mechanical regulator, which avoid the complexities of electronic systems. The water heaters are easy to install and come with a five-year warranty on the tank, though the electrical components have a shorter warranty. Despite its benefits, some users noted the absence of a thermometer and occasional dripping from the check valve. Additionally, one user reported high electricity consumption and issues with the thermostat casing. Overall, the Tesy GC K51 is a solid choice for quickly heating small amounts of water, with a European build quality.

I was tired of washing my hands and parts in the workshop under ice water, so I decided to buy a small storage water heater. The device had to be simple, reliable and quickly heat water. I took a risk, took a boiler from a Tesy brand unknown to me and was pleasantly surprised. Normal equipment, good assembly and the most pleasant experience of use. Heats water instantly. Ten liters at a temperature of about 65 degrees are ready for use in just twenty minutes. And simply hot water for hand washing is ready in just ten minutes. This is important for me because sometimes there's simply no time to wait. Compact size. It's very easy to find a space for it. Installation is also not complicated. I did everything myself in two and a half hours. The control is mechanical, which means it's simple and reliable. No hassles or glitches with electronics – the good old thermo-mechanical regulator won't let you down. The tubular electric heaters are also quite ordinary, not the fashionable "dry" ones. Good protection of the storage tank. There is a classic enamel coating and a protective anode. Yes, even in such small models, this manufacturer installs electrochemical protective defense. It has all the necessary protections: against overheating, overpressure, and running without water. Made in Bulgaria, i.e., within the European Union. There is every reason to hope that the quality is also "European". Water is dripping from the check valve. As if this is normal, but this very water, in my opinion, is too much. |
I recommend not making the same mistake. If you want to ruin your mood and home experience, buy a Tes Y boiler. In a week, the much-praised thermostat casing crumbled like firewood. None Uses a lot of electricity. use Tesy GCU 1015 K51 month or more i recommend it don't buy |
I live in my own house and I heat water in winter using a powerful heating boiler. However, there's no point in turning it on during the summer just to wash dishes or take a bath. That's why I bought two water heaters to warm up the water – a 100-liter one for the bathroom and shower, and this small 15-liter Tesy for the kitchen. This separation makes sense to avoid keeping the large water heater constantly on, plus the distance from the kitchen to the bathroom is quite significant. The 100-liter device prepares water on its own by the timer, ready by the evening, while the small Tesy provides water for dishwashing and other household needs. Its small size allowed it to be hung right above the sink. It looks attractive and fits well in any spot, even in visible locations. In the kitchen, it's essential to get hot water as quickly as possible, and with this task, Tesy performs much better than its bulkier big brothers. For dishwashing, the water heats up in just about 15 minutes, and it reaches the maximum temperature of seventy degrees after half an hour of waiting. The internal tank of this boiler is a scaled-down version of the classic large water heater, meaning it’s made of two-millimeter steel with a glass-ceramic enamel coating. Well, since even the best enamel eventually cracks, there is an additional magnesium alloy anode. The warranty for the electrical part is one year, which is not much, and the tank has a five-year warranty. The manufacturer is located in Bulgaria, so it’s a true European product. The only thing this boiler truly lacks is a thermometer. |
