Visualise the data

Explore the whole database visually. Hover or tap any point to see the product; click it to open full specifications. Use the filters to narrow the dataset across every chart.

COP vs Maximum capacity

Efficiency against heat output. Larger units sit to the right; higher points are more efficient. Note that COP is measured at differing test conditions — colour shows heat-pump type.

Maximum heating capacity (kW, log scale)

SCOP vs Maximum capacity

Seasonal efficiency against heat output — a more realistic year-round figure than a single COP test point. Note that SCOP is measured at differing test conditions — colour shows heat-pump type.

Maximum heating capacity (kW, log scale)

Maximum heating flow temperature

Heat pumps grouped by the hottest water they can deliver for heating, with bars coloured by type. Click any band to list the models in it and open full specs.

Number of heat pumps in each band

Cost vs Maximum capacity

Retail price against heat output, using the average of the price range where a range is published. Only products with UK retail pricing data appear here.

Maximum heating capacity (kW, log scale)

Charts reflect the manufacturer-published figures held in this database. COP and SCOP are measured at different test conditions across products (shown in each product's detail view) — compare like-for-like where possible. Points with missing values are omitted from the relevant chart.

Heat Pump Database — heatpumpdatabase.com

1. Overview

This website provides a searchable database of heat pump products available in the UK market, alongside technical guidance and educational content. It is intended for informational and comparison purposes only.

2. Informational Use Only

All content, including product specifications, performance data, and technical articles, is provided for general information purposes only. While reasonable efforts have been made to ensure accuracy by sourcing data from manufacturer datasheets and official documentation, no guarantee is given regarding completeness, reliability, or suitability for any particular technical, commercial, or operational use.
