Last year, in summer, I decided to radically upgrade my home heating system and completely stop using gas. The gas boiler was successfully replaced with a solid fuel one, which primarily uses wood as fuel (luckily there's a forest nearby, so they can be bought relatively cheaply). However, the hot water issue turned out to be more complex. To address it properly, I bought this versatile combined water heater. This water heater can operate using two energy sources. During the heating season, the main heat source becomes the heating circuit of a solid fuel boiler. Inside the boiler, there is a special spiral heat exchanger for this purpose. As soon as the heating season ends and the boiler is shut down for the summer, electric heating takes over, managed by a single immersion heating element with a power of 2000W. The power is substantial, but the water heater is also sizeable, so it doesn't heat up very quickly. The heating is controlled mechanically using a rotary dial. The maximum water temperature can reach 85 degrees, but the manufacturer explicitly recommends using a range of 50 to 60 degrees. You can go higher, technically there's no problem. However, heat losses through the tank insulation (foam polyurethane) would also increase in that case. The tank is well protected from overheating and excessive pressure. Compared to the old gas water heater, the initial significant inconvenience was the slowness of the new water heater. Heating water from 20 to 60 degrees takes more than two and a half hours, and if the water is freshly added and cold, around 10 degrees, you have to wait significantly more than three hours. In short, you need to plan ahead, or else if something urgent comes up and the water isn’t ready, you’ll have to wait anyway. |
Gorenje TGRK 80 NG is the basic model in the family of combined water heaters under the sign of the Slovenian brand with a tank of 80 liters and a spiral heat exchanger. The older brothers of the boiler are available in 100 L, 120 L, 150 L and 200 L configurations.
Water heating variability
The device will satisfy the hot water needs of a family of 2-3 people. In the cold season, the boiler is connected to an external source of thermal energy in the manner of a gas or solid fuel boiler, at the end of the heating season it prepares hot water with its own hands. For this purpose, the built-in heating element with a power of 2 kW is provided in the design of the water heater.
Anti-corrosion qualities
The tank of the model is equipped with an anti-corrosion magnesium anode and covered with high-quality enamel. To prolong the life of the heater, the manufacturer recommends servicing it every two years. In appearance, Gorenje TGRK 80 NG is indistinguishable from most colleagues in the shop — the boiler is made in a traditional cylindrical shape and has small dimensions of 77.5x45.4x46.1 cm.
conscientious work
The only complaint about the model is the slow heating of water using a heating element (from 10 to 60 °C in more than 3 hours). Through the heat exchanger, the water in the boiler tank reaches the condition much faster (from 15 to 45 °C in 17 minutes). An indicator of the approximate level of heating is a bimetallic thermometer on the front panel. The boiler cannot be reproached for dishonest work, which is one of the main pros in favor of the model, along with affordable cost.
