Home Energy Efficiency Kit v2

Welcome to EnviroShop's Home Energy Efficiency Kit.

In this kit you'll find a number of tools to help you discover where your house is wasting energy and enable you to devise a plan to help stop that wastage. Each kit contains a water flow meter, an ambient temperature thermometer, a spot temperature non-contact infrared thermometer, and a power meter.


Energy Saving Thermometer

Heating appliances that are running too hot or cooling appliances that are running too cold use excess energy, cost more to run, and do not last as long.

Adjusting thermostats and other temperature settings is one of the simplest ways to cut your energy use. You'll also save money and help protect our environment.


Place the thermometer in the middle shelf of your fridge or freezer and check the temperature after the thermometer reading has stabilised. If the temperature is below 3 °C for the fridge or below -18 °C for the freezer, adjust the thermostat to achieve the temperature shown on the thermometer.

Handy Hint

Keeping some space behind the fridge improves air circulation and fridge efficiency.

Heating and Cooling

Place the thermometer in your living rooms and check the reading later on. Adjust your thermostats so that your room temperatures are between 18 °C and 20 °C in winter, and 25 °C and 27 °C in summer.

Handy Hint

Closing curtains on cold nights and hot days and sealing drafts can make a huge difference in reducing heating and cooling costs.

Hot Water

Water heaters that store your hot water should be set to between 60 °C and 65 °C to reduce health risks from dangerous bacteria. Instantaneous hot water heaters should be set at 50 °C.

Handy Hint

Improving the insulation on uninsulated hot water pipes is an easy way to reduce energy losses. Plumbing suppliers can supply the insulation.

Non-contact Infrared Thermometer

Used for measuring spot surface temperatures rather than ambient area temperatures, the Non-contact Infrared Thermometer is ideal for checking the temperature of items such as window frames, doors, and walls to see where the heat or cold is leaking into your house.

  1. Hold the thermometer by its grip and point it towards the surface to be measured.
  2. Pull and hold the trigger to turn the meter on and begin testing.
  3. Release the trigger and the HOLD display icon will appear on the display and hold the last measurement made for reading.
  4. The thermometer will power down automatically 10 seconds after the trigger is released.

Power-Mate Lite

Warning: This product contains live mains voltages and should be used only by an adult or under adult supervision. If the power cord or case becomes damaged, please return to either the manufacturer or an authorised service company for repair. Do not use in wet areas or if the unit becomes wet.


The Power-Mate Lite (PML) reveals Running Cost, Energy Use, Greenhouse Gas (G/Gas), all expected meter readings (including VA & PF), and it has a selectable timer function built in for taking readings over a preset period.

The PML is the easiest to use energy and cost meter that is currently available. Not only is it simple to use but importantly the results are also easily understood.

Although you may be impatient to use the meter straight away, to get the best results from your PML please take a little time to read these instructions before taking measurements.

Plug in the PML and press the buttons freely as described whilst reading the text to familiarise yourself with the PML operation.

The PML Overview

It will be helpful now to describe the operation of the three buttons from left to right. The buttons all have two operations, one for a short press or “click”, the other for a longer press or “hold”.

General Precautions before using the PML

  • The Power-Mate is intended for indoor use only.
  • Do not use the Power-Mate if the case or cord is damaged.
  • Do not use the Power-Mate if it becomes wet.
  • Avoid using the Power-Mate in bathrooms or wet areas.
  • Use the Power-Mate with sine-wave power sources only i.e. mains power or inverters labelled as “pure sine wave”.
  • Do not use the unit with “Quasi sine wave” or square wave inverters, as the Power-Mate may be damaged.
  • Do not expose the Power-Mate to excessive heat i.e. a vehicle in direct sunlight, to avoid damage to the case.
  • Do not dismantle the Power-Mate, there are no user serviceable parts inside and a shock hazard exists.

The PML is limited to a maximum capacity of 10 Amps. If you are unsure of the power required for an appliance, the power (or current) rating is usually written on the unit’s label or even cast into the plastic or metal of the appliance. Alternatively refer to the appliance’s user manual in the specification section or contact the manufacturer.

Menu Button

“Click” the Menu button to display the different modes, these are: Cost, Greenhouse Gas, Energy, Meter and Time screens. Each mode (except time) displays multiple lines of information in a small font.

Zoom Button

In the various modes the un-zoomed first line of information is presented with the first word in reverse video (white on black) we shall refer to this as the “cursor”. “Click” the Zoom button and the cursor will toggle to the next line, “hold” the Zoom button to magnify the information contained in the cursor line to double size allowing it to be read easily. “Click” the Zoom button whilst in the magnified mode to toggle through each line in sequence. “Hold” the Zoom button to revert the screen back to un-zoomed – or simply “click” the Menu button to un-zoom the screen and change to the next mode in one step.

Run Button

Click the “Run” button to start stop or pause a measurement period, “Hold” the Run button to erase all the data, a message prompts “clear all data Yes/No ?”, selecting Yes clears all the stored data.

When the meter is running (during a measuring period) the top right hand corner of the display has a flashing activity icon, when paused a “II” symbol is displayed. After the PML has been reset the activity icon is not displayed until the Run button is pressed again to start a new measurement period.

Entering Cost and Greenhouse Gas information

When in the COST screen mode, “hold” the Menu button until the Set Cost screen appears. Click the Zoom button to change the flashing number, click the Run button to select the next digit and so on.

When finished setting the cost, click the Menu button to exit the set up mode.

When in the G/GAS screen mode, hold the Menu button until the Set G/GAS screen appears, enter the Greenhouse Gas value in a similar fashion as for entering cost in the previous step. When finished setting the G/GAS, click the mode button to exit the set up mode.

Setting the measurement period

When in the RUNTIME screen mode, hold the Menu button until the SET TIMER screen appears. Click the Zoom button to select the desired run time. If no RUNTIME period has been selected then when run, the PML will count time upwards continuously until manually stopped.

When a RUNTIME period has been selected, pressing “Run” will load the timer with the selected run-time and the displayed time will count downwards until zero is reached causing the meter to stop. Note it is best to stop and clear the Meter before setting a new Runtime.

When finished setting the desired RUNTIME, a short press of the Menu button will exit the set up mode.

Starting a measurement period

Before starting a new measurement period, always clear all the old data from the meters’ memory. Press and hold the Run button until prompted “ ERASE ALL DATA NO?/YES?, press the button under the “Yes” prompt to clear all the old data (or select No to retain the data).

When the meter is running during a measurement period it is OK to “click” the Menu button to change through the various modes to view the data in real time, or to use the Zoom button.

If the appliance being measured is cyclic in nature i.e. it starts and stops automatically, such as a fridge or similar thermostatically controlled device, the data for estimated cost, greenhouse gas and energy will be more accurate if measured for a longer period. For continuous cyclic appliances such as a fridge it is best to measure over a 24 hour period (or a longer complete multiple of 24 hour periods).

Screen Back-light

The screen back-light is automatically turned off after 30 seconds but will be turned on again for another 30 seconds if any of the buttons are pressed. The best button to use, if you do not want to change modes or start /stop the unit, is the Zoom key.

When the back-light is off the first click of the Zoom key does nothing except turn on the back-light, of course pressing the Zoom button whilst the backlight is on will toggle to the next line of data as usual.

Power failure during a measurement period

If the power is interrupted during a measurement period an “unplugged” icon will be displayed next to the activity icon in the top right corner of the screen to inform you of a power failure. Although the meter will resume what it was doing automatically without loss of data after a power-failure, for best accuracy, if the period of the power failure is not known, the measurement should be taken again.

When measuring a refrigerator for 24 hours a short power failure will have little effect on the data, but an extended loss of power could lead to inaccurate data, especially for estimated quarterly or yearly calculations.

To clear the “Power Fail” icon, simply reset the meter by holding down the Run button as described above in the “starting a new measurement” section.

Screen Descriptions

In the Cost, G/Gas, and Energy screens, information for the actual, hourly, quarterly and yearly periods is provided. These values will be displayed and continuously updated once the PML is “Run” or started.

Cost Screen

Cost values are provided in dollars and cents for the actual, hourly, quarterly and yearly periods. The “actual” value is the cost to run the appliance since the test was started. The hourly quarterly and yearly values are calculated from the data collected to date, since the measurement period started. The values are displayed and continuously updated once a measurement period is in progress.

G/Gas (Greenhouse Gas) Screen

Greenhouse Gas emission values are given in kilograms for the actual, hourly, quarterly and yearly periods. The “actual” value is the greenhouse gas emissions released, in kilograms, through the use of the appliance since the test was started. The hourly quarterly and yearly values are calculated from the data collected to date. The values are displayed and continuously updated once a measurement period is in progress.

Energy Screen

Energy usage values are provided in kilo-Watt hours for the actual, hourly, quarterly and yearly periods. The “actual” value is the actual kilo watt hours of energy consumed by the appliance since the test was started. The hourly quarterly and yearly values are calculated from the data collected to date. The values are displayed and continuously updated once a measurement period is in progress

Meter Screen Definitions

The meter screen provides technical information, which may be of little interest to non-technical people.

  • True Power (Watts) – The actual power used, which the energy provider bills you for.
  • Apparent Power (VA) – The power figure calculated from the sum of RMS Volts x RMS Amps.
  • Volts – The RMS AC voltage available for supply to the Load.
  • Amps – The RMS AC current drawn by the Load.
  • Power Factor – The ratio of True Power to Applied Power.
  • Frequency – The alternating frequency of the mains voltage.

When zoomed in, Minimum and Maximum values are logged and displayed for the True and Apparent Power, also for Volts and Amps. The Min and Max values are only logged during a measurement period (PML is running) and can be cleared by holding the Run button.

Suppressing unwanted Screens

It is possible to prevent any unwanted screens from displaying. If your interest is just cost for example, it is possible to suppress all of the other screens.

When in the RUNTIME mode hold the Menu key until the Set Timer screen is showing, now press and hold the Menu key again until the Set View screen is showing. Now click the Zoom button to shift between the choices and click the Run button to Y to display a screen or NO to remove it. When finished screen selection, click Menu to exit back to normal.

Of course enabling the screens again is simply a reversal of the above steps, but answering Y (yes) to the screens to be enabled.


When the load current exceeds 10A, the display flashes the message “WARNING, OVER/LOAD”, disconnect the excessive load as soon as possible to avoid overloading and damaging the Power-Mate.

Water Flow Measuring Cup

Measure your flow rate in 3 simple steps:

  1. With the handles pushed together, place the Water Flow Measuring Cup under water until the water is overflowing.
  2. With the water still running, slowly pull the handles apart until the water stabilises at a consistent level.
  3. Read the measurement on the side of the cup. This is the flow rate.

Important: Aerators attached to the end of the spout must remain completely immersed in the water inside the cup during this test.
