Free, independent specifications, performance data and COP test conditions for residential and commercial heat pumps from UK manufacturers.
Specifications are extracted from manufacturer datasheets and published technical documentation, and every data point is then checked by a human before it goes live. Each listing records the source it came from, and where a manufacturer quotes performance at non-standard test conditions, those conditions are stored alongside the figure so you can compare like with like.
Datasheets get revised and we do make mistakes, so every product page carries a “Suggest a correction” link. Corrections are genuinely welcome.
Select units from Browse, then review side-by-side here.
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.
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.
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.
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.
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.
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.
Browse by appearance. Many heat pumps look similar in a spec table but differ a lot on a wall or in a garden, so this view leads with the photo. Filter by the basics, then click any unit for its full specification.

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.
All content, including product specifications, performance data, and technical articles, is provided for general information purposes only.

Product specifications should always be verified directly with the manufacturer before making purchasing or design decisions. Users should seek appropriate professional guidance — including MCS-certified installers and qualified engineers — before specifying, purchasing, or installing heat pump equipment.
Product data is compiled from publicly available manufacturer datasheets, product information sheets, and official brochures. Specifications including COP, capacity, noise levels, dimensions, and other performance metrics are reproduced as published by manufacturers at their stated test conditions. Actual installed performance will vary depending on site conditions, system design, and operating parameters. No warranty is given as to data accuracy, completeness, or currency — manufacturers may update specifications without notice.
