How does electricity consumption of a vacation home differ per season?

In winter, heating is the largest cost item, in summer cooling, and that difference can amount to hundreds of kWh per week combined. Occupancy and external equipment such as a swimming pool pump or hot tub also play a role. With a fixed rental price, you as the landlord bear that seasonal difference yourself; with separate electricity consumption, it shifts to the guest. How much difference this makes for your property depends on insulation, climate and equipment present.
