Hi, welcome to our app which is designed to give you a first pass assessment for a heat pump in your building. It will make a recommendation for an Air Source Heat Pump based on your inputs and standard information, you can download the data sheet at the end.

This app doesn't replace the need for a specific energy and engineering assessment of your project but it will give you a starting point. Contact us to discuss your project, we'd also like to hear your feedback on our app.

We will continue to add functionality to this app over time. If your project involves complexities such as; reclaimed heat, industrial processes, grid flexibility services or PV integration please get in touch straight away.
