The cold climate heat pump sizing support tools help users to select cold climate air source heat pump (ccASHP) products that are sized to best match the peak and annual heating needs of a home or heating zone. The tools, functioning within the NEEP ccASHP Product List website, include a search function and a product-level analysis. The search function helps view multiple products based on search criteria and select products for further analysis or comparison. The product view displays system and load-matching
data, providing a visual for how a specific heat pump’s capacity matches the heating and cooling loads across the home’s seasonal temperatures.
