Knowing the differences between heated vs non-heated storage is an important first step when choosing a storage unit for winter. But temperature is only part of the equation. The type of items you’re storing, how often you need access, and how much space you require all play a role in finding the right solution. At Maple Leaf Self Storage, we offer flexible winter storage units and seasonal storage solutions for homeowners and businesses across Calgary and Vancouver, with knowledgeable staff ready to help match you with the best option for your needs.

Start with What You’re Storing

Before selecting a unit, consider the types of items going into storage:

Furniture, mattresses, antiques, or wooden items
Electronics, appliances, or televisions
Documents, photos, or keepsakes
Seasonal décor and clothing
Sports equipment, tools, or durable outdoor gear

Valuable, temperature-sensitive items benefit from climate-controlled storage, while more durable belongings may be suitable for heated or non-heated units. Understanding what you’re storing helps determine the right level of protection.

Heated vs. Climate-Controlled vs. Non-Heated Storage: What’s the Difference?

It’s important to understand exactly what storage providers mean by temperature control:

Heated Units

Provide consistent warmth (often around 5 - 10°C) using forced air, helping prevent freezing and manage humidity. These units are suitable for many household items during winter.

Climate-Controlled Units

This premium option maintains stable temperature and humidity year-round. Climate-controlled units are ideal for artwork, antiques, electronics, documents, and wooden furniture, offering protection from cold, heat, and moisture.

Non-Heated Units

These units provide shelter only, making them best suited for durable items such as tires, metal tools, or outdoor equipment. Choosing between heated vs non-heated storage depends largely on what you’re storing and how sensitive it is to temperature changes.

Why Climate-Controlled Storage Units Protect Your Property Better

The risks of storing your belongings in unheated spaces during winter often outweigh the savings. Plastic items can become brittle in extreme cold, while glass and ceramic may crack. When frozen items are brought into warmer air, condensation forms, leading to mold and mildew on fabrics, paper, and wood. Metal tools and bicycles may rust, and documents or photos can warp or grow mold due to humidity shifts. Wood furniture absorbs moisture, expanding and contracting as temperatures change, which can cause warping, splitting, or veneer separation. Leather becomes stiff and brittle, leading to cracking and loss of shape. Electronics are especially vulnerable, as internal condensation can cause short circuits, and batteries may freeze or corrode. If your belongings are worth storing, they’re worth protecting with climate control.

Choose the Right Unit Size for Your Winter Storage Needs

Storage isn’t one-size-fits-all. Unit size depends on what you’re storing:

Small units work well for boxes, seasonal décor, and documents
Medium units fit furniture from apartments or home offices
Larger units accommodate multiple rooms, appliances, or business inventory

If you’re unsure how much space you need, Maple Leaf Self Storage experts can help estimate the right size so you’re not paying for more space than necessary - or struggling with too little.
