If anyone needs a very long burning, then this boiler is perfect. But it still requires attention and frequent cleaning. You can take long breaks between loads, because once you fill the combustion chamber with firewood, you can not worry about the boiler for a day. A very original wood combustion technology with the so-called “upper combustion”. There are no problems in the event of a power outage, because everything that is regulated and adjusted in the boiler works on a mechanical principle and does not require power supply. The boiler is generally controlled in an elementary way - by regulating the draft with the help of a bimetallic device. Firewood in the boiler burns very slowly and this heat is almost completely converted into the heat of the coolant. Due to the low speed and long burning time, an expensive heat accumulator is not needed. Ash accumulates at the very bottom, but often it will not be necessary to clean it. It really depends on the wood. In the worst case, you will have to tinker once a week. Firewood eats different, but it is best to load medium and large chocks of not very resinous species. Coniferous wood with slow burning gives a lot of resinous pollution. The longest operating time and the best calorific value was obtained on “euro firewood”. But they are pricey. It produces a lot of soot and tar. It is necessary to thoroughly clean every 40-50 days, otherwise problems with draft in the chimney begin. And the devil pulled me to make a meter horizontal section in it. The boiler burns for a long time, but it does not reach the declared 30 hours. I got 25-26 hours maximum There is an extra air leak at the bottom of the boiler. I suspect that the installers messed up, in vain the company service did not call. use STROPUVA S20 month or more |
2. This boiler needs to be bought with brains. Or install them additionally. Requires a minimum number of approaches. Everyone who writes that it burns for more than 20 hours quietly. They scratch, I think, for one of two reasons: 1. Ordered review. 2. They don’t want to look like SUCKERS. What led to very good advertising. The boiler burns in quiet mode for no more than 12 hours. use STROPUVA S10 month or more i recommend it don't buy |
The name of Lithuanian boilers STROPUVA has become almost a household name when it comes to inexpensive models of long-term burning on solid fuels. Over the years of being on the market, the brand's products have won a lot of fans due to their high reliability and balanced performance data.
Top burning
In operation, the S15 model, designed for heating a “square area” of about 120 m², uses the principle of upper combustion — the fuel is burned in a thin upper layer, as it burns out, the flame gradually sinks lower and lower. The process of its descent can last more than a day, after which it will be necessary to load a fresh batch of firewood into the combustion chamber — the main source of energy that STROPUVA S15 “lives on”.
Cylindrical "matryoshka"
At its core, the boiler is a "matryoshka doll" of two steel cylinders. A space for the coolant is provided in the cavity between their walls. Also, due to the barrel-shaped form factor, the model is devoid of a tendency to create a pressure difference inside. There are two doors in the body of the device: firewood is laid through the upper one (unfortunately, you can’t call it convenient), and the lower one serves to periodically empty the compartment where ash accumulates.
Deserved Success
The STROPUVA S15 additional equipment includes a bimetallic draft regulator, the range of tasks of which is to ensure even combustion when the specified temperature is reached. Thanks to it, excess heat is not produced. The whole thing works without being connected to the power supply in offline mode. In the bottom line, the model is justifiably one of the most popular representatives of the kind of long-burning solid fuel boilers at the junction of the low-cost and medium price segments.
