the energy-smart home: heat water efficiently - home energy storage system

Should you choose gas or electricity for hot water heating?
At first glance, natural gas seems to be a viable option.
The system is not much more expensive to install than the electric cylinder, the pipeline gas is said to be cheap, burn clean, and-
If you have an "instant" system
Will you run out of water.
You will also give a great help to the Earth and future generations. right? Perhaps not.
Double check, there are some fish hooks with gas
It has to do with inefficient systems and falling into fuel that is ultimately unsustainable.
With the depletion of large gas fields in Maui and the replacement of several smaller ones, we see a sharp rise in gas prices --
In terms of actual value, in the past decade, compared with 50% of electricity, it has increased by 32% (
Source: Department of Consumer and Business, Innovation and Employment).
It is still a cheap fuel compared to electricity.
However, it is inefficient when you add it (
You lose 20% of your energy as heat when the atmosphere is running)
And supply costs, not much inside.
Bottled LPG prices are higher, in part due to increased transportation costs.
If it's an instant system-
This will surprise most people.
From 20 to 30 times the use of hot taps per day, another 15 to 25% of the accumulated energy is lost to the atmosphere.
Also, save the power of water when you have instant hot water --
This happens when you have a cylinder that can run out of hot water
It doesn't exist anymore, so we usually use more.
Dana Darwin, energy consultant and director of New Zealand energy alternatives, said: "The end result is that the efficiency of the gas instantaneous system is 60-70% and the efficiency of the gas storage system is 55-65% (
Mainly due to additional station heat loss)
Match greenhouse gas emissions. " While non-
From an environmental point of view, renewable natural gas is no longer popular, and heat pump technology for water heating has become the mainstream.
According to research by New Zealand energy alternatives, some heat pump systems are now the most energy efficient of all options-
Including solar energy (
Depending on your location)-
As a result, greenhouse gas emissions are the lowest. When well-
They are designed and installed at least three times more efficiently than the electric cylinder, so you can get 3kWh (

A price.
The downside is that the installation cost of most heat pump systems is higher than that of electric and gas cylinders, but some newer full-in-
A model that includes cylinders is only a little more expensive than a gas replacement.
New Zealand power is now three-
Therefore, select an efficient "power" system
Heat pump, for example-
From the perspective of carbon emissions, this is a good choice. Low-
Since the price and efficiency of the heat pump water heater varies from model to model, the cost saving option is your homework.

Look at their water heating system tools.
Before you spend money to replace the old thermos, do a quick test of your shower flow first.
If you can fill a 10L bucket in less than a minute, then you use more water than you need.
Since most of our hot water use is in the shower, replace the head in the form of low flow, or install cheap flow --
Restrictor will save you money and reduce greenhouse gas emissions immediately.
Almar Italian shower eco air shower-
Manufacturer Almar developed water
According to your water pressure, saving technology can reduce water consumption by half, they say.
Shower is our largest hot water usage, hot water heating accounts for about 1 out of 3 of the average energy usage of New Zealand homes, you can save water and energy with an efficient shower head.
Almar's EcoAir shower head uses the Wenzhu effector jet effect -
Where water flows at a higher rate.
Therefore, the pressure is not the amount of water used for washing.
In addition, they combine air and water to get the whirlpool effect, resulting in a feeling of more water, and as such, Philips touted it as "the most closely connected bulb in the world ", to maintain the emotional and massage experience of the shower, Philips tone may completely change the way we use and experience the light.
Wireless LED light bulb (only 8. 5 watts)
It is possible to screw into existing lamps and replace incandescent lamps with lower efficiency.
But this is just the beginning.
These seemingly smart lights are then wirelessly controlled by apps linked to WiFi modems and remote "bridges.
Use the app to adjust the lights based on any color, any brightness, and schedule.
Set the timer so that the lights that are turned on unnecessarily turn off automatically.
With this control, you will only use light at the level you need when you need it, reducing your energy consumption.
Pure Audio class A single amplifier is not the first energy-saving product.
Aren't they all high wattage to get a big voice?
Pure Audio in Wellington tested the myth and found that the actual power consumption is usually as low as 10 watts.
For the sake of safety, their class A single power amplifier can hold 65 watts.
It automatically goes back to low power standby mode when not in use.
But the most significant feature is probably the least wasted.
And related energy savings.
In manufacturing
The aluminum plate used to make the shell is the structure and self-ventilated.
Most importantly, the triangular aluminum sheet removed in order to make the vent hole is then reused as a radiator inside the product.
This series is possible with funding for energy alternatives.
