What is your average electricity bill?

[bozzman101]

mine in a 3 bed bungalow small pool 1600 a month

pool only requires 2 hours in morning and evening = 500 b a month

air con for sleeping a few hours fans for rest looking tv etc comp

If you run a 2.0 Horsepower Pump for 6 hours a day it will use 9 units of power.(1.5 units / hour)
The current charge on a bill a couple of months old is: 2.4778 Baht / unit, plus 0.9255 Baht / unit fuel tax, for a total of 3.4033 Baht / unit.

So for 31 days that is 279 units, = 950 Baht. Plus 7% VAT on the total bill.

If the pump is 1.5 HP it will use 6.75 units for 6 hours, or 1.125 units / hour.

In Bangkok the MEA have a sliding scale based on the units consumed. It appears the PEA has a fixed rate, at least for domestic users.

The same calculation can be used for air-cons, but you have to take a stab at how long the compressor is actually running while the unit is turned on, and it is also influenced by how often it cycles on and off.

Of course, if your power is charged by the Developer, all bets are off!

Not sure what you mean by this , Pete? An electric motor is not like a car engine that will start to lose efficiency as it wears out, especially if not serviced properly......

Yes, true. I shouldn't equate age with more electric usage. My experiences have all been with brand name. One in a Pattaya rental house where the pump was old and simply burned out. I forget what the owner replaced it with but my electric bill mysteriously decreased by several hundred baht monthly. Second was in our house here where the pool package came with "Espana" brand filter and pump. The pump sounded like a 747 on takeoff, and replaced under warranty twice with the same brand. Finally ripped it out and replaced with a Hayward Super Pump and again, the electric bill went down several hundred baht. Pete

Any impeller friction will draw more current at the motor.

Not sure what you mean by this? The total "head" that a pump has to push against consists of a lot more than any "friction" that may be caused by the impeller. Pump hydraulics are a science in themselves.

Hayward are good pumps, but they use crap motors. They are also not of a suitable frame type for tropical use. Another fact with them is all the performance graphs that they publish are based on a 60 Hz supply, where the RPM of the motor is around 3450, compared to running on 50 Hz supply where the RPM is around 2850. The HP output is also about 10% less than claimed on the nameplate, regardless of it saying 50Hz.

Unless pumps and electrics have changed in the last decade, anything that makes the motor work harder is going to draw more current. Worn bearings, distorted shaft, debris in the impeller housing, incorrectly sized piping, restricted water flow.

None of which are "friction on the impeller".

I thought "friction on the impeller" was a good thing... that's why I've always hated condoms!

Not sure why you've misquoted me. Debris in the impeller housing will cause friction and shaft distortion can cause impeller rubbing, as can an incorrectly fitted impeller. Google 'impeller friction' or have it your own way. I care not.

Hi there
i have small pool 6X4 m, washing machine and aircon running in the beedroom the hole night.
last months bill 3.850 with an average of 3.200 for the last 3 months. The pool pump was running 3 hours X2 pr. day, I have now ajustet it to 1 hour in the morning and 1 hour in the late afternoon, and will see what that will do to my bill wich I think is to high.

Can anyone tell me (approx) how much their average monthly electric bill is please? Please can members answer who have a pool, no dishwasher, washing machine, and use gas for cooking. The agent has just told me that the months bill is 4000 baht which seems high. We only have aircon on low in one bedroom at night and use fans in the day when home. Thanks

It seems high? Sorry but bloody hell yes it seems astronomical to me. Ditch the pool for a while Siani. Ask the Agent to explain how he arrives at that figure. Check your meter reading regularly - and get someone you can trust to check out the cabling as well. You might just be feeding a local stall or neighbour with electricity.
I would start by turning everything off and go look at your meter.

And with what you save on your power bill, you can put towards buying chemicals to get your pool back to a usable condition after it turns green!

There are many variables, but it is generally agreed that the total volume of water in a domestic below ground pool, SHOULD be completely cycled through the filter and sanitizing system, twice in 24 hours.

You need to know the theoretical output of the pump in gallons per minute, (or litres if you prefer), and the total volume of water in your pool. The volume is easy to find, the pump output not so easy. You can then come up with a reasonable starting point of the number of hours required to achieve the required cycle.

I would strongly suggest that you do NOT reduce the run time as you have stated, but maybe start reducing 15 minutes at a time, until you see some obvious signs of both a change in appearance and the chemical balance. It is also advantageous to run the pump early in the morning before the sun gets to high, and late in the evening after the sun starts to go down.

This subject needs a thread of it`s own, so no more from me.

8000 - 9000bt per month ! 10 x 5 Pool,1 Air-con on during the night,washing machine on everyday,fan on in daytime.

I guess you didn't know about Google when you asked all the questions in this post?

I do not need to use Google for knowledge like this, I just base it on 50 years af actual hands on practice.
