Model overview based on user reviews
The Atlantic OPro Small PC series offers compact and efficient water heaters, ideal for small spaces like workshops or under-sink installations. Users appreciate the quick heating capability, likening it to an electric kettle, with the ability to heat water to nearly 70 degrees in just 20 minutes. The model is praised for its good thermal insulation and protection against overpressure and overheating. However, the warranty requires regular maintenance, including replacing the magnesium anode every two years, which can be costly if a specialist is needed. Despite this, the product is seen as a practical solution for those needing a reliable source of hot water without extensive installation work.
Pros
Cons
Good for under sink, heats up quickly. Ease of assembly and installation. Looks like a flimsy temperature controller to me. (But this is more of a nitpick than not enough - once adjusted and forgotten) use Atlantic OPro Small 15 SB month or more i recommend it should buy |
My house stands on the side of a busy highway that goes from Kharkiv to Kyiv, and since I have a large spacious garage on the site with a drive directly from the road, Gd himself ordered to open a small car repair shop with tyre fitting. At first he worked on his own, then his eldest son joined in and began to help, clients began to appear who returned to us. This mini boiler was bought specifically for the workshop. Hot water is sometimes needed for equipment and, of course, for washing hands. Running to the house turns out to be long and inconvenient. 10 liters is exactly the volume that we need. That is, in reality, it allows you to select 6 liters of really hot water from it, and then the temperature drops rapidly. Thanks to such a modest volume and powerful heating element, the water heats up like in that electric kettle, very quickly. In just 20 minutes, the temperature reaches almost 70 degrees, that is, when diluted in warm, it turns out from 12 to 15 liters. Designed for a working pressure of 8 atm. This never happens to me, usually not higher than 3.5-4. It has good thermal insulation made of polyurethane foam. There is protection against too high overpressure and overheating. There is a five-year warranty on the tank, but not everything is so simple. Such a guarantee will continue if the boiler has been regularly serviced and the magnesium anode has been replaced, which must be done every two years. To do this maintenance and replacement of the anode, the stump is clear, should be a specialist from an authorized service, who, of course, wants money, but in order to come to our tiny town he wants a very immodest amount of money. So I guess I'll only have a two year warranty. |

P.S.
I tried tankless water heaters, I took two for 6 and 8 kW, tried both, and returned both. It's either boiling water or cold, heats with a low flow. Sometimes the sensor doesn't work. You need to blow it out with a water stream before switching off. In short, a headache, although payment for electric power probably would have been cheaper. But forget that kind of savings.
