New H&V System For Waitrose Store


The Weatherite Group of Companies has worked together on a major contract to replace the heating/ventilation system at Waitrose, Frimley which is part of the supermarket division of the John Lewis Partnership. Weatherite’s complete solution included new features that have met all the design criteria to improve customer comfort and the working environment of partners.

The contract is part of a national programme of Waitrose store upgrades by the John Lewis Partnership. Weatherite won the contract following a recent Weatherite Building Services contract for the JLP R22 replacement programme and the success of Weatherite Manufacturing in supplying high energy efficient Air Handling Units to Waitrose.

Weatherite designed the system in conjunction with PSH Consulting Ltd, the JLP’s nominated consultant. The work included the supply and installation of two new air handling units made by Weatherite Manufacturing, together with ducting, fan units, wiring and a new control and electrical power panel. In a separate contract, Weatherite also provided and fitted steel support frames for the AHUs.

The project incorporated a number of beneficial design features that are new for JLP and Waitrose. A return air system has been fitted above the dry goods zone to induce air movement across the store, improve comfort conditions and increase the energy efficiency of the operating plant. The existing ceiling void fan heater units were relocated and new temperature sensors installed to give better temperature control across the dry goods zone. Weatherite also replaced entrance door heaters with new high efficiency models to reduce any draughts in the checkout area.

Weatherite also overcame a number of challenges as all the work had to be carried out after store operating hours from 8pm to 6am.
