Installation of boilers of modern designs, using various types of fuel, allows you to ensure an optimal level of comfort in residential or industrial premises. There are many modifications of such equipment, taking this into account, before you buy this or that device, you should study the market. Modern single-circuit floor-standing gas boilers with a cast-iron heat exchanger use the most common and cheapest type of fuel - gas.

Such equipment can be installed not only in residential buildings, but also in any other buildings where constant autonomous heating is required, the only condition being a natural gas supply. Modern production offers a choice of single-circuit and double-circuit devices, so some gas boilers have very simple heating and water distribution schemes.
Many stores are engaged in activities such as selling gas boilers; as a rule, they have a wide range of different models, differing in many respects, including the installation method.

Both Russian and foreign gas boilers are sold; their prices are much higher than ours. When installing water heating devices on gas, you need to think about the chimney, and when making a choice between wall-mounted and stationary devices, you should know that for wall-mounted and floor-mounted boilers, project preparation is required and permission from government authorities is required. Prices for gas boilers are set depending on the use, power and area of ​​the heated object.
