What we did in the house in the summer to reduce heating costs in the winter. Identified three main heat losses at home

Several years ago, my family and I moved to a private house. My house is located in the 5th climate zone and is 70 square meters. Three rooms, kitchen, toilet, bathroom, corridor. The walls are made of rubble stone 25 cm wide, the facade is decorated with a "fur coat" (this is one of the types of plaster), the roof is slate, the windows and doors are wooden.

After some time, we found out that the heat goes away:

· Through poorly insulated windows - from 10 to 35%;

· Through walls - 25-35%;

· About 5-15% of home heat goes out through the door.

Gas and electricity tariffs are constantly growing, so one of the logical ways to save money was to properly insulate our house.

Outside doors are the first protection of a house against external natural factors. We chose the middle price category, size 950 x 2000 mm, metal - 1.5 mm thick, sealant - mineral wool and two seal contours on the box and the canvas. The metal doors turned out to be more airtight, heat and noise insulating.

Having installed high-quality windows, we practically forgot about the problems with energy saving. They do not freeze, do not corrode, the profile does not deform. The glass has a protective film that does not let heat through in summer and does not release heat in winter.

When the turn came to replace the boiler, they chose a floor-standing single-circuit gas boiler, like most consumers, due to the fact that it is more economical and easy to operate. Some may argue that electric boilers are also easy to operate, but since we live in a remote area, power outages are unfortunately not uncommon for us.

On the advice of a specialist, the boiler was taken at the rate of 1 kW of power per 10 square meters of area, that is, a boiler with a capacity of 10 kW was needed for a room with an area of ​​100 square meters. The work process is fully automated. This type of boiler is suitable for those people who want to spend money once and buy reliable equipment that does not require much maintenance.

Additionally, a circulation pump was installed, which increased the heat transfer of the system. Its main feature is efficiency, small size, noiselessness, durability. My heating system is welded from cast iron pipes with a diameter of 50mm, which we are gradually replacing with bimetallic radiators, which currently have a higher heat dissipation, are relatively easy to install and have an attractive external view.

The next step, no doubt, was the insulation of the facade of the house. One of the most affordable materials for facade insulation is expanded polystyrene, in the common people often referred to as polystyrene foam. We chose foam plastic with a thickness of 5 cm, a density of 25 kg / m3. With such parameters, it is suitable for thermal insulation of walls, roofs, floors, house facades.

After completing all the steps for warming the house with foam plates, we applied decorative plaster "bark beetle". Its advantages are that it provides relative strength to mechanical stress, additional sound insulation of walls and good vapor permeability. Also, one of the advantages is the ability to maintain a decent appearance of the house for many years.

Thanks to all the operations we carried out to insulate the house, replace windows, doors and modernize the heating system, we began to save 30-35% on utility bills.
