As Canterbury locals, we understand first-hand the devastating impact earthquakes can have on homes and communities. That’s why the team at New Zealand Heat Pumps is committed to correctly installing and securing all heat pump and hot water heat pump units using earthquake restraint systems – so your equipment stays stable when it matters most.
Large systems like hot water heat pumps and cylinders carry significant weight, meaning they must be properly braced and secured to reduce movement during seismic activity. Without correct seismic restraints for HVAC equipment, these units can shift, topple, or damage surrounding services – leading to costly repairs, water damage, electrical risks, and in serious cases, injury to your family.
Why earthquake restraint systems matter
Earthquake restraint systems help secure heating and ventilation equipment to minimise movement and prevent failure during seismic events. When an earthquake occurs, any inadequately restrained mechanical or electrical system can create a domino effect of damage – not only to the unit itself, but to flooring, pipework, walls, and other parts of your home.
Proper restraint reduces the risk of:
- Equipment toppling or shifting
- Damaged water connections and leaks
- Electrical hazards
- Costly repair or replacement
- Injury to people nearby
- Damage to surrounding walls, flooring, and internal services

Recent installation: Hot water heat pump in Oxford
Take a look at this hot water heat pump we recently installed at a home in Oxford, secured using triple strapping on the 270-litre cylinder to ensure it stands up to seismic movement. This is an example of how the right earthquake restraint system makes a real difference – adding stability, compliance, and peace of mind for the homeowner.
Some FAQs
Are earthquake restraints required for heat pumps in NZ?
In New Zealand, seismic restraint is required where a building element or building service needs to remain stable during an earthquake, and this is typically achieved by following current NZ Building Code requirements and relevant standards. For some HVAC equipment, especially heavier units or equipment mounted in elevated or exposed positions, seismic restraints may be required or strongly recommended to help prevent movement, damage, and safety risks during seismic activity.
What is triple strapping and why is it used?
Triple strapping helps secure heavy cylinders against movement. It’s commonly used for added stability in earthquake-prone regions like Canterbury.
