Nu-Heat’s experienced team of project designers worked with Octagon to create a bespoke heat pump solution that successfully met all of their outlined requirements.
We worked closely with Octagon and their building services team to design a heat pump solution for Crossacres, supplying a fully integrated ASHP system. The solution provided was far removed from any off the shelf packages on the market.
We designed and supplied a Dual 3 phase 2300 20kW NIBE ASHP with automatic pressurisation unit, two 500ltr buffers, a 540ltr DHW cylinder, a driveway de-icing system with bespoke blending valve and heat exchanger assembly together with boiler back-up. The solution also utilises Modbus KNX integration with property home automation software.
This is a heating system that gives the homeowner complete, flexible control. It’s everything they could possibly need.

Bespoke documentation for all operational and maintenance aspects, including the end user handover manuals, were supplied to Octagon to pass on to the homeowner/maintenance team for the property.
