RHI Calculator

This calculator is for working out the estimated running costs, savings and RHI payments for a proposed heat pump or solar thermal system.

You can use it at the start of a project to give you an idea of the financial viability of a system before you commit to it.

The RHI calculator allows you to choose and compare the various technologies – solar thermal panels, ground source heat pumps or air source heat pumps – work out what payment tariff you can receive and provides an estimate of RHI payments you can expect on a quarterly basis.
