Question

Семья проживает в частном доме. За период опалювального сезона семья потребляет около 4000 м³ газа. Стоимость 1 м3 газа составляет 7 грн. Было решено заменить обычный газовый котел твердотопливной стоимостью 26 000 грн. За какой срок окупится новый котел, если на отопительный период семья будет тратить на дрова около 20000 грн?​

Answer 2

To calculate the payback period for the new solid fuel boiler, we need to consider the cost of the boiler and the savings from using firewood instead of gas.

Cost of the new boiler:

The cost of the new solid fuel boiler is 26,000 грн.

Savings from using firewood:

The family consumes approximately 4,000 m³ of gas during the heating season. The cost of 1 m³ of gas is 7 грн. Therefore, the total cost of gas consumption is 4,000 m³ * 7 грн/m³ = 28,000 грн.

However, the family has decided to switch to using firewood, which will cost them approximately 20,000 грн for the heating season.

Calculation of payback period:

To calculate the payback period, we need to find the difference in costs between using gas and firewood.

The annual savings from using firewood instead of gas can be calculated as follows: Annual savings = Cost of gas - Cost of firewood Annual savings = 28,000 грн - 20,000 грн = 8,000 грн

Now, we can calculate the payback period by dividing the cost of the new boiler by the annual savings: Payback period = Cost of new boiler / Annual savings Payback period = 26,000 грн / 8,000 грн = 3.25 years

Therefore, it will take approximately 3.25 years for the family to recoup the cost of the new solid fuel boiler by using firewood instead of gas.

Please note that this calculation assumes that the cost of firewood remains constant over the payback period and does not take into account any maintenance or operational costs associated with the new boiler.
