Typically an electric and heat pump installation takes approximately 3-4 hours. A solar hot water installation usually takes a full working day. Your hot water supply will be interrupted for that day only and will resume the following day. All our solar and heat pump installations are performed by solar endorsed technicians. In Queensland solar and heat pump installers must hold this endorsement to be able to perform your installation. The installation of a tempering valve is required on all installation to comply with AS/NZS 3500.4 and forms an integral part in the installation. We will even take away your old system free of charge. On completion of installation a Form 4 ‘Notifiable minor work is lodged to the Queensland Building and Construction Commission.
