Maximum Safety Measures

The ATEM VPG-20M gas water heater offers a high level of safety in everyday use thanks to a well-thought-out set of technical solutions. The device monitors flame presence to prevent gas leaks, is equipped with a draft sensor to protect against carbon dioxide entering the room, and features overheat and excessive pressure protection. Additionally, it is designed to automatically shut off in the absence of water in the system, which helps protect the heat exchanger from damage. The flow-through gas water heater is independent of the power grid, as it operates on batteries and turns on automatically when water is supplied using a built-in piezo igniter. This makes the model convenient and safe to use for children, the elderly, and is generally well-suited for household conditions. The settings are adjusted using two rotary knobs responsible for flow strength and heating level, and the display shows the current water temperature at the outlet, reducing the risk of burns.

Build Quality

The manufacturer has paid attention to the reliability of the design and the durability of all key components. The heat exchanger is made of pure oxygen-free copper with thick walls, resistant to corrosion, and designed to heat water up to 60 degrees Celsius. The 20 kW power and 10 l/min capacity are sufficient for simultaneous hot water delivery to several points in an apartment or private house. The model is also suitable for installation in multi-storey buildings, as it can operate stably at low water pressure from 0.5 bar. The hydraulic group is made of brass, resistant to oxidation, condensation, and increased pressure up to 6 bar. As a result, the water heater combines decent build quality, reliability, and affordable price.
