  • Why electricity bills increasing notably and how to manage?

    Electricity bills in New Zealand have been increasing notably, and here’s a breakdown of why that's happening and what you can do to lower them:

    A. Why are power bills so high?

    • Higher Power generation, transmission and distribution cost.

    • Seasonal demand change, billing or rate changes.

    • Uncontrolled power consumption.

    • Lack of understanding on electricity management and energy saving.

    B. Ways to lower your electricity bill

    • Understand the electricity consumption.

    • Get to know your appliances and energy consumption.

    • Upgrade and calculate return of investment (ROI).

    • Manage electricity.

    i.e. Calculation - Comparison of Heat Pump into Traditional Heater

    Heatpump

    Heat Pump – 5kW

    1 Hour of Use

    5kW×1hr = 5kWh

    COP assume 3.5

    5kWh / 3.5 = 1.43 kWh

    Cost at $0.35 per kWh:

    1.43 ×0.35 = $0.50

    Add GST ≈ $0.6

    Traditional Electric Heaters

    Traditional Electric Heaters – 2 kW

    1 Hour of Use

    2kW×1hr = 2kWh

    NO COP

    2kW×1hr = 2kWh

    Cost at $0.35 per kWh:

    2×0.35 = $0.70

    Add GST ≈ $0.8

    Example. Heat Pump scenario

    • Service your heat pump to work maximum COP.

    • Think about the outdoor unit and clean.       

    • Check heat pump hight.

    Install proper place.

    Use Ceiling Fans on Low Speed in initial stage

    • Check heat pump thermostat.

    • Try to close required heated area

    • Use smart doors or curtains.

    • Set an Optimal Thermostat Temperature

    • Use Timer and Smart Controls

    • Avoid “Auto” Mode for Extreme Conditions

    • Upgrade to Modern Inverter Models

    • Preheat Before Peak Hours

    • Switch to a Time-of‑Use Plan

  • Why do you need a battery backup to stay connected during power outages?

     

      Power outages are more than just an inconvenience—they can disrupt your ability to stay connected, communicate, and access essential services. In today’s digital world, where most phone services rely on internet connections and electrical power, having a battery backup system is no longer optional—it’s essential.

    The Hidden Impact of Power Cuts

    When the lights go out, most modern phone systems, including VoIP (Voice over Internet Protocol), immediately stop working. This means:

    • No landline calls

    • No internet

    • No emergency communication

    For businesses, this can result in missed customer calls, lost sales opportunities, and an inability to provide critical services during outages. For homes, it can mean being cut off from family and emergency responders when you need them the most.

     

    How Battery Backups Keep You Connected

    A battery backup acts like a safety net for your communication systems. Here’s how it helps:

    • Keeps Your Modem and Router Powered
      Even when the grid goes down, your internet connection stays active.

    • Ensures Your Phone Stays Operational
      VoIP and cordless phones need power. A backup keeps your line open.

    • Supports Emergency Devices
      Critical devices like security systems, alarms, and medical alerts can keep functioning.

    How Long Will It Last?

    Most battery backups provide 2 to 8 hours of connectivity, depending on the size and devices connected. This is often enough to handle short-term outages or until you switch to an alternative power source.

    Who Needs It the Most?

    • Homeowners in outage-prone areas

    • Businesses reliant on customer calls

    • People using VoIP or fib                  er-based phone systems

    • Anyone who wants peace of mind during emergencies

    Final Thoughts

    A battery backup is a small investment with big benefits. It ensures your internet, phone, and essential devices stay on when the power goes off, keeping you connected when it matters most.
