Custard boy Posted September 2, 2022 Share Posted September 2, 2022 Due to the rising cost of domestic electricity in Thailand I would now like to try and understand more and if possible reduce my home electricity usage. I know that my current electricity monthly costs may not seem very large . My home is fairly small and only inhabited by my self and wife , but any decrease in the electricity running costs would be some thing that I would appreciate. These below are electric items I currently have installed in and around my house. 1. LG smart TV 2. Electric shower unit 3. Combined fridge / Freezer ( Cooling digital inverter compressor ) 4. Top loading washing machine ( no electric heating elements ) 5. 5 floor standing electric fans ( intermittent use ) 6. 1 Air conditioner unit ( Inverter – 18,000 BTU ) 7. Microwave ( with internal electric grill ) 8. 1 Electric kettle 9. Assorted house internal lighting 10. Assorted exterior house flood lighting ( LED ) 11. Assorted small electric / electronic equipment ( computer / router / security cameras etc ). The one air conditioning unit is only used for a short time before going to sleep and does not run all night or during the day time. I have looked at the residential electric unit costs web sites. https://www.mea.or.th/en/profile/109/111 https://www.pea.co.th/Portals/1/demand_response/Electricity Tariffs Nov61.pdf?ver=2018-11-21-145427-433 This is a screen shot of my current electricity bill . I have also ordered one of these ( hoping that it may help me to understand my home electric consumption better ) Any advice , suggestions or comments that may help me better understand and possibly reduce the current house electricity usage costs , would be most appreciated. Thanks. . Link to comment Share on other sites More sharing options...

Popular Post daveAustin Posted September 2, 2022 Popular Post Share Posted September 2, 2022 Try having cold showers every other day, or reduce shower time, see how that helps. Showers and aircon tend to be the biggest culprits. Make sure fridge not running too cold. How much do you use that microwave grill? 2 1 Link to comment Share on other sites More sharing options...
Popular Post sometimewoodworker Posted September 2, 2022 Popular Post Share Posted September 2, 2022 2 points that will reduce usage, though how much is debatable, are turn off or unplug every device that has a standby mode. The TV will probably need to be unplugged. So is the saving worth the probable need to reprogram the tv? But if there is no problem you will save a tiny amount. The second point is to change the fans to DC ones. This will drop the usage by about ⅓ for each fan. The problem with that is that I only know of a few makers of DC fans and those are all ceiling ones and the cost will almost certainly wipe out the savings available. So on a pure saving money basis a bad idea. However the ones I have are extremely quiet, much less noise than any of the standard floor standing ones. 2 1 Link to comment Share on other sites More sharing options...

No need for solar lights Regarding the Power Monitor shown, surely that will only show the consumption on that particular socket/outlet, and not for the whole house. I have fitted a monitor in my consumer unit/fuse box, which tells me the daily and overall consumption. I also read my meter every day and put the readings into an app so I know exactly how much I use each day/month. What is the payback time if solar powering is fitted? The increase in cost from Bht 4 to Bht 5 per unit is only for over 300 units per month. Edited September 2, 2022 by KannikaP 1 Link to comment Share on other sites More sharing options...

Electric kettles are typically 3 kW, and are usually filled with much more water than you need. Get a pan on the gas hob, or boil exactly the right amount in the microwave....a mug of water takes 2 minutes. 1 1 Link to comment Share on other sites More sharing options...

I have got Mr Ken AC ceiling fans which take 30 watts each so in 12 hours take 360 watts = one third of a unit= Bht 1.5. Not really worth worrying about. And they are inaudible. The noise comes from the movement of the air, not the actual fan. 1 Link to comment Share on other sites More sharing options...

Please show where that number comes from. I have about 20, so if they use 0.5 watts each x 24 hours = 240 watts = 1/4 of a unit = Bht 1 ! which will increase if I switch the light on, no? They are rated at 3 watts each on full power, which is far too bright for me, I have them on 20% usually. But all of them full on for 12 hours would be 20 x 3 x 12 = 720 watts = 3/4 of a unit = Bht 3 per day Edited September 2, 2022 by KannikaP 1 Link to comment Share on other sites More sharing options...

Popular Post connda Posted September 2, 2022 Popular Post Share Posted September 2, 2022 Roughly $40 USD ? You have to be kidding? You should be celebrating that you don't live in the West where you'd be paying $1500 GBP/Euro/USD month and rising. I'm not embracing austerity because it's now in vogue. But each to their own.

The report says between 0.06 and 0.43. for three samples. I turn the power to the bulbs off in the daytime, so not really worth worrying about.

My previous quote was referring to the maximum allowable under the Energy Star Logo spec. The U.S. and Canada sold LEDs tend to be of the highest available quality products currently on the market. Your particular samples can consume much more than the allowable maximum of 0.5 W. What's is your brand? 1 Link to comment Share on other sites More sharing options...

Why would you need to reverse a ceiling fan please? One of the fans only blows air well when in reverse due to its placement 2 of the others get reversed occasionally due to temperature differential and high level ventilation. I didn’t factor the reverse capability when I bought. I did factor in the silence of them I was also pleased with the power consumption. However one lightning strike has probably wiped out any power savings, it rather convincingly blew up one of the chips and the psi of the lights.

Popular Post transam Posted September 2, 2022 Popular Post Share Posted September 2, 2022 Tell the ladies in the house, a shower only takes 2 minutes, not 30. Replace all lighting with LED, checkout the LED wattage to your stuff equivalent to do the same job. Fill any open space in fridge/freezer with plastic bags etc. Periodically, pull the fridge/freezer out, turn off the power to it, unscrew the panel covering the gubbins, clean out all the <deleted> build up with vacuum and brush, ensure air can be pulled in and expelled by the fridge gubbins cooling fan. Don't take too long doing it if you have frozen chips. ???? I bought switched twin plug sockets for regularly used stuff, saves pulling plugs all the time, plus they have small LED lights telling you if an appliance is still switched on, very handy.. 2 1 Link to comment Share on other sites More sharing options...

Yes for an electric cooker but not when you have gas available beyond the fact that there are a lot of criticisms of the microwave for health. 1 1 1 Link to comment Share on other sites More sharing options...
