The pool heater setup.
Progress report after a hiccup with a wire which found it's way loose, we replaced the timer and re wired it sent it back, 3-4 days later phone call, saying the controllers doing it's job, the pool dropped to 12c while we fixed the controller and sent it back via courier, it's now 25 degrees and we have been swimming in it. The heater is putting out 75c into the pool at a slower rate of 10 litres a minute.
He said he had a few issues with it starting to smoke a little and ash build up around the diffuser, but removed the diffuser which has cleaned it up. The diffuser worked in the past, but now back to just an open bowl which is doing the job.
By heating the pool, you start to make a hole in the ground you pour money into most of the year for a couple of months, start being a pleasure again to use, yes it takes a little effort but it's not costing much to heat. The benefits of having a heated pool over most the year instead of a freezing pool must be amazing feeling. I'm not sure if chemicals have to be increased with a heated pool but we'll find that out soon.
A Pool Heater currently heating a 20,000 litre pool. Which I'm now informed the pool is 48,000 litres. With one 15m copper coil. Pools this size normally has double the amount of coils to heat this size pool. The rate which heating is happening above, two coils will heat 48,000 litre pool in 2 days heating to 25c amazing that is a huge amount of water.
Email from pool owner.
Oil, and right now the heater is taking in water from the pool at 14c and pumping out at 70-75c I discovered that my previous source of oil had antifreeze and water mixed with the courtesy of the apprentice, who thought the drums of waste oil was the place he was supposed to put it.
The first thing Chris has given a name to the beast, "Dragons Breath", not that she smells bad, just because it has alot of flame inside her.
The other thing to note is this is only being use during daylight hours only.
"Dragon Breath" pet name for the burner is working well. Got the pool up to 20C now which was 12c yesterday.
He is running it 1 second pump 5 seconds delay. The ash build up alot quicker now as oil flow has increased I'm looking at 4-5 hours, we are looking into sending him a new type of disfuser to stop this from happening, we have recommended to change to Hydraulic oil for no ash build up.
Got abit of hard ash buildup especially under the diffuser. Started poking around it, as the heater started to smoke, so gave it a belt with the poker, got a burst of flame and immediately the thermostat readout shout up from 50c to 100c then went to error mode, water was boiling coming out of the pool outlet, the tape holding on the censor water pipe melted and the censor fell off. Might need to mechanical fastening for that.
Housed under a lean to which protects it from the weather with a small pump to circulate the pool water throught the copper coils inside the heater, otherwise using thermosyphon, the water was entering the pool boiling hot and was splattering. Hence the pump.
We made a house call to Dannevirke to get this heater up and going, and to get some temperature reading for ourselves.
We got it going with ease and after 20 minutes, it was taking the pool water in at 9c and heating it to 47c. This week Chris the pool owner called, and said the pool temperature has raised from 9 C to 14 degrees celsius after 4-5 days heating, but only during daylight hours, has the heater being used, as he's only new to this type of heating, and he's only got has his learners licence currently. Next week he'll have his full. Lol
He's has reduced the delay time from 6 seconds to 5 seconds and has increase the output temperature to 52 celsius.
He said he was very happy with the heater and what it was doing.
I would have thought that to heat 20,000 litres would take two weeks of heating to rasie it from cold to a swimmable temperature.
We felt the pool needed a cover to try and keep the heat in, and insulate the pipes would help.
He has since made a cover for it.
The other option is a ceramic blanket wrapped around the heater, this would also put even more heat into the water. The emission where a heatwave with no smoke at all, as you can see in the quick video below. Excellent. Thanks Chris.

Sandblasted and un-repainted.
The low lying spa pool heater.
Heating spa pool via thermosyphon
3-4 hours to 39-40C. And could be kept going on low once temperature has been achieved, to keep the heat up in the pool.
If the unit was to be covered in ceramic blanket then this time would be shortened.
Run on Canola Oil or Vegetable oil, clean burning with fan controller.
These sell for $1199.00 NZD BUY NOW
A coil ready to be fitted into a cylinder.
1 coil will heat a pool twice as big as the blow up kids pool at the bottom of this page.
Under the Hawke's Bay Airshed, these heaters can only to be operated using Canola oil. Although will work with most waste oils.
Our heaters have been viewed by 3 members of the District Council and has been approved under the building & emission.
So long as you do not store more than 5000 litres of waste oil on your property, and feed you heater with a 20 litre container, have safety oil collection setup in the case of a spill, have the correct fire protect against walls and ceiling. If installed inside a home then permits etc would be also required, however as 99 percent of these heaters are installed outside away from buildings, designed to heat your spa pools, or pools. In fact there are no laws regarding outside heating, so long as you are not smoking out your next door neighbours you are within your rights. We sell these heaters to councillors to heat pools and spa pools, so if there happy with them, so are we.
The Regional Council says you can't burn Canola oil because it comes under Waste oil. Well this needs to be looked into if the EPA says it outside of the HSNO Act and ok to be used as a fuel, and you can burn it in a diesel car, or in a commercial business. It really does make you start wonder, e.g. there's a huge company across the road from the council heating the whole business with waste engine oil, I have seen it going at one stage not at it's best, billowing out thick black smoke OMG, however i'm sure it doesn't run like that normally.
The book Animal Farm springs to mind.
And the EPA.The EPA manages the Hazardous Substances and New Organisms Act 1996. Under this Act, only hazardous substances that are intended to be imported into or manufactured in New Zealand require a HSNO approval.
The EPA respnded to my email by Dr David Weller, EPA with his reply, Please note that, according to the information available at the time 2016, Canola oil was deemed to be non-hazardous, and therefore would be exempt from the HSNO Act., it would probably be wise to seek advice from your District Council or Regional Council.
All the best.
We do mean well, just the odd question now and then.

Now to heat water you ideally need a pool cover or indoor to speed the process up.
You need a good source of waste oil, ideally hydraulic oil for 24/7 heating.
If burning 24/7 you'll burn a 44 galon drum a week.
Setting the pool up as easy as cold pipe out, hot pipe into the pool.
Wetbacks used a double coil for swimming pools over 20,000 litres. Above 20,000 litres we can fix a third coil fitted inside the other two coils.
So that's 45 metres x 12.7 mm. And it will run all off 12 volts with very litte power consumed so yes, free pool heating. You do have to light it at the moment.
These are also used where the customer wants a split system to feed radiators and spa pool from the one burner boiler unit.
Water from radiators gets a dirty colour to it, which you don't want mixing with your hotwater cylinder or spa pool.
These are the coils used for a 70,000 litre pools.
They consist of 3 x 15 metre coils 2 x 280mm diametre and the center coil 150mm diametre all joint to a 25mm inlet outlet using plumbers sil fos for the solder.
This setup is currently $1000.00 NZD worth of copper coils, plumbing fittings, sil-foss, Mapgas and lots of hours of work. Depending on the pump thiese coils will produce temperatures over 70c at 400 lites an hour.
We don't sell these with the extra washers/fins on.
