The pool heater setup.

A Pool Heater currently heating a 20,000 litre pool. Housed under a lean to to protect from the weather with a small pump to circulate the pool water throught the copper coil 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 it'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 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 he pool needed a cover to try and keep the heat in, and insulate the pipes would also help.

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.

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.

Copper coils built for spa pool heating.

                   A coil ready to be fitted into a cylinder. 

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.

We have been working on these heaters now for 10 years, on and off, we now have then to the stage where there is no smoke at all, even at startup or shutdown, and now pretty well full automated with the help of electronic timers, thermostats & optional Wifi. 

I have looked at the neighbours approved clean air wood fire, which smokes badly for 1/2-3/4 of an hour before they get to temperature, and smokes again as more wood entries the fire we start to ask ourselves, what's going on. I give them credit soon after warm up there is just a heatwave exiting the flue, but it still could operate alot cleaner than it is.
The other thing which gets me, is farmer Joe living on the town boundary, can light his 4 years collection of rubbish he's been stacking up with the odd tractor tyre, and smoke the town out.

Oh, also found out everyone is within the law to light an open fire or contained fire to cook on. So if you need a hotplate welded onto your waste oil heater let us know.

At least we are not like India, burning tyres for power generation, you need to check this out on youtube. The kids are being born with all types of defects the people dying of cancer. Their air must be different to ours.

It is possible to burn tyres cleanly, but better we need to look into gasifying them back to the materials they were made with. 3 litres of diesel can be recoverey from evey car tyre, I have looked into it but would require large funding to set up. Presently most tyres here end up in landfill, the council says, a real shame. 

All the best.
