Nu-Heat's heat pump solution for Crossacres, Wentworth Estate

Octagon required an efficient heat pump solution designed to handle a large heat load for their prestigious luxury new build ‘Crossacres’ on the Wentworth Estate. The system needed to comfortably supply heat/control to the domestic hot water and towel rail circuits, heat the indoor and outdoor swimming pools, and feed the vehicle garage ramp for de-icing.

Nu-Heat’s commercial team worked closely with Octagon to design and supply a bespoke heat pump solution.

The NIBE Dual ASHP 2300 20kW was the ideal product to meet Octagon’s requirements and is particularly suited to larger, commercial applications. The advanced controllers allows for individual control of multiple swimming pools and boiler back-up, while NIBE Uplink enables remote access to the heat pump for the end user. Its CoP levels are among the best on the market and it can operate in temperatures as low as -25°C.

Nu-Heat also designed, built and supplied a bespoke centralised control panel. Features included functionality to alert maintenance of any errors in any part of the system, the ability to isolate and control the plant room switch gear from a single location and 10 alarm signal management.

Andrew Butt, Field Sales Manager – Commercial Division and Gary Dommett, Technical Account Manager, said,

“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.”
