Heat Pump Terms and Conditions
The following terms apply to standard back-to-back heat pump installations supplied and installed by Chris Odlum Electrical Ltd.
What Is A Back-to-Back Installation?
A back-to-back installation is where the indoor unit is mounted on an exterior wall and the outdoor unit is positioned directly behind the indoor unit on the outside of the building.
The outdoor unit will typically be mounted on a wall bracket or installed on a suitable PVC mounting slab, depending on site conditions and installation requirements.
Pricing and Quotations
All advertised pricing, package deals and promotional offers are indicative only and subject to a site inspection.
A written quotation will be provided following assessment of the property. Pricing is not confirmed until a written quotation has been issued and accepted by both parties.
Standard Installation Inclusions
- Supply and installation of the nominated heat pump system
- Standard back-to-back installation
- Up to 4 metres of refrigeration pipework between indoor and outdoor units
- Supply and installation of up to 22 metres of electrical supply cabling from the existing switchboard to the heat pump installation.
- Supply and installation of a new appropriately rated MCB (miniature circuit breaker) in the existing switchboard, provided there is sufficient space and the switchboard is suitable.
- Standard wall penetration and weatherproof sealing
- Electrical connection, testing and commissioning
- System setup and customer demonstration upon completion
Access Requirements
- Single-storey residential dwellings
- Safe and unobstructed access to all work areas
- Suitable mounting locations for indoor and outdoor units
- Adequate roof space and/or underfloor access where required
Multi-storey installations, difficult access, roof work, scaffolding requirements or other access restrictions may incur additional charges.
Electrical Requirements
The electrical connection method will depend on the size of the heat pump, the condition of the existing electrical installation, and the available capacity of the electrical circuits. Heat pump sizes below refer to rated cooling capacity.
Heat Pumps Below 5.0kW
Smaller heat pumps will generally be connected to a suitable nearby existing power circuit, provided the circuit has sufficient capacity and meets current electrical safety requirements.
Heat Pumps from 5.0kW to Below 7.0kW
The existing electrical circuit will be assessed to determine whether it can safely accommodate the additional load of the heat pump.
Where a suitable existing circuit is available, this may be used. If a new dedicated circuit is required, the additional electrical work will be quoted separately and discussed with the customer before proceeding.
Heat Pumps 7.0kW and Above
Standard installation pricing includes an allowance for a new dedicated electrical supply circuit, including up to 22 metres of electrical cabling and the installation of a suitably rated MCB (miniature circuit breaker) at the existing switchboard, provided the switchboard has sufficient space and is suitable for the installation.
Cable Route and Access Requirements
Where a new electrical circuit is required, standard installation pricing assumes suitable and accessible roof space and/or underfloor access is available to provide a practical cable route from the switchboard to the heat pump location.
If a suitable concealed cable route is not available due to restricted access, building construction or other site limitations, an alternative installation method may be required, such as surface-mounted conduit or trunking.
Any additional materials, labour or alternative cable installation methods outside the standard installation allowance will be treated as a variation and quoted separately for customer approval before proceeding.
Additional Electrical Requirements
Any switchboard upgrades, additional electrical protection, circuit alterations, cabling beyond the standard allowance, or remedial work required to achieve a safe and compliant installation will be quoted separately and discussed with the customer before proceeding.
All electrical connections will be assessed and completed in accordance with applicable New Zealand electrical standards and regulations.
Additional Costs
- Pipework exceeding 4 metres
- Electrical cabling exceeding the included 22-metre allowance for heat pumps rated 7.0kW cooling capacity and above
- New dedicated circuits required for smaller heat pumps where an existing suitable circuit is unavailable
- Alternative cable routes, including surface-mounted conduit or trunking, where suitable roof or underfloor access is unavailable
- Switchboard alterations or additional electrical protection beyond the standard installation allowance
- Switchboard upgrades
- Additional drainage requirements
- Decorative trunking or ducting requests
- Building alterations
- Difficult access requirements
- Unsafe or non-compliant existing electrical installations
Any additional work identified during installation will be discussed with the customer and approved before proceeding.
Wi-Fi and Smart Controls
Wi-Fi control modules, smart home integration and remote-control functionality are not included unless specifically stated within the quotation.
Travel
Standard pricing applies to installations located within 20 kilometres of Te Awamutu. Additional travel charges may apply outside this area.
Warranty
Manufacturer warranties apply to all equipment supplied.
Chris Odlum Electrical Ltd warrants workmanship in accordance with New Zealand consumer legislation.
Warranty does not cover misuse, lack of maintenance, accidental damage, power supply abnormalities, weather events, vermin, corrosion or alterations carried out by others after installation.
Payment Terms
A deposit of 50% of the quoted amount is required prior to commencement of work.
The remaining balance is payable upon completion of the installation or within 7 days of invoice date unless otherwise agreed in writing.
Acceptance
Acceptance of a quotation constitutes acceptance of these Terms & Conditions.
