What is heater stardew valley?

In Stardew Valley, heaters are used to keep animals warm during the winter season. They are purchased from Marnie's Ranch for 2000g and require coal to function. The heater functions as long as there is coal in the animal's feeding trough, and it keeps the animal's happiness level from decreasing due to the cold weather. The heater can be upgraded to the deluxe version, which costs 7500g and has a larger area of effect, allowing it to keep more animals warm at once. The deluxe heater also requires iridium instead of coal to function. Overall, heaters are essential for keeping animals healthy and happy during the winter months in Stardew Valley.
