How far away can a heat pump be from a house?
Guidelines for header pipes for air source heat pumps
The tables below are designed to help you to select the right size pre-insulated header pipe for your project, up to a maximum of 100m from the property. They pertain to our pack solutions with buffers only.
Note: for custom systems or bufferless packs a custom calculation is required to ensure that there is sufficient Remaining Head Pressure For Heating Circulation (H/m). Please contact us for more information as the size of the circulating pump and/or heating system itself will have an impact on the calculation.
