What is stardew valley heater?

Stardew Valley Heater is a tool that can be purchased from Robin's Carpenter Shop for 2000 gold and 10 refined quartz. It is used to keep animals warm in cold weather, preventing them from losing happiness and productivity. The heater can be placed inside barns or coops, and it consumes coal to keep the temperature warm. The heater has a 3x3 tile coverage area, meaning it can keep several animals warm at once. It is most useful in winter, as during this season the game's temperature drops, causing animals to lose happiness and productivity. The heater is a must-have if you want to keep your animals happy and productive throughout the year.
