Answer:
an increase in the price of natural gas will increase demand for his electrical heating systems
Explanation:
In this question, electrical heat pumps and natural gas are substitutes
Substitute goods are goods that can be used in place of another good.
if the price of a good increases, the demand for the substitute increases and if the price of the good reduces, the demand for the substitute increases.
If the price of natural gas increases, the quantity demanded of natural gas would reduce in line with the law of demand. According to the law of demand, the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded
As a result of the increase in price of natural gas, consumers would increase their demand for electric heat pump and there would be an increase in demand for the good
