Autonomous heating systems, which are used in private houses and some apartments, are much more profitable than standard central systems. Indeed, in this case, the owner himself can regulate the power of the heat supply, and you can also install such a system that would meet your requirements in terms of efficiency, energy consumption and maximum heating power. To increase the efficiency of the equipment, you can use additional tools, such as buffer capacity , which is also called a heat accumulator, because it allows significantly extend heating and reduce costs.
If you are interested in boilers for heating a house, then you should pay attention to those that are designed specifically for private one and two-story houses, since nowadays, there are more and more small wall options for apartments, the capacity of which is not enough for a private house. It is best to choose from official suppliers or manufacturers. In the case of domestic manufacturers, everything becomes much easier.
If you are not particularly versed in the technical features of products, and on sale sites you can often find detailed descriptions with a list of technical characteristics, then you can use consultation by phone or via the Internet. Taking into account the fact that the layout and volume of many houses is the same, it will not be difficult for specialists to find the right boiler for you. If you have been using old-style boilers for a long time, then modern models can be very surprising, since with a relatively small size they can have a fairly large power, as well as much higher efficiency.
So don't be intimidated by small models. Floor-standing varieties are much more powerful than wall-mounted ones, so it is better to buy them for private houses. In addition, an electric pump can be added to the system to pump warm water faster. This further increases the efficiency of the system, especially since you will have to use the pump, and, accordingly, waste energy only at the initial stages, until all the pipes in the house are warmed up.
