Hot Tub Lazy Spa Alternative Heating/temperature maintenance

[@michaelhoffmann2891]

Brilliant idea! While we love our new Maldives (Xmas pressie to ourselves), it's a bit of a shocker how slow it heats and how much power it still uses. I'm a bit torn: we actually have a 12.5kVA solar system, so it's "free". What costs is the reduction in grid feedback for which we get paid. We're trying to get rid of gas use here complete, so it'd be a step backwards. However... 3 hours instead of having to remember in the morning to turn it on to use it in the evening... tempting. Very tempting.

Great setup I went through 3 standard tankless water heaters in a year because of leaks I am assuming because of chemicals

[@NeoRioFX]

I bought a 12L (3.2 GPM) tankless water heater to help speed up the heating of my 290 gallon (6 person) hot tub. I’m not sure which pump I should buy to pump water to the heater. I want a 110v pump that I can plug in to a socket (probably into a programmable electric timer, so I can time the pump to go on every 20 minutes as a work-around for the 20-minute timer shut-off most tankless water heaters have.) Since the purpose of running the tankless heater is to save time and money, it seems that a cheap pump would make sense, one that doesn’t consume a lot of electricity since it will be running a lot…and most likely at the same time as my hot tub’s own pump will be running. The 12L heater puts out a maximum of 3.2 GPM, (the intake’s suitable water pressure is: Min. 0.02MPa and Max.0.8MPa…I’m guessing that 0.8MPa is close to 3.2 GPM, but I haven’t been able to verify that) so it would seem that I should be looking for a pump that (lifts the water about 4-5 feet) and pumps no more than 3.2 GPM (or maybe even a pump that allows control over how fast the water is pumped in order to have more control over how hot the water gets on the first pass through the heater). It makes sense that it would be better to slow the water flow to the heater if that meant getting water as hot as you want it on the first pass, rather than waiting for the whole tub’s water content to pass through the heater multiple times to reach the desired temperature. Most of the ½ HP pumps I’m finding seem to pump around 6 GPM which seems to be too strong a water flow into the heater to get the water really hot on the first pass. I’ve been looking at some very small submersible pumps, even as small as fish tank pumps that are tiny and run at 40 watts or thereabouts. The numbers seem to add up as they say that they push 3 GPM, though I’m not too sure about the lift rate. The fact that they run under water seems to be nice in the sense that they must be quieter than pumps that sit outside on the floor. Some of these small submersible tanks have dials to control the strength of the water flow which seems like would be nice to easily adjust how fast the water goes into the heater thus controlling how hot the water is when it comes out. Any suggestions on which pump(s) I should look at for what I’m trying to do would be greatly appreciated! Thank you.

[@pyromaniac354]

I would use a small 12v pump and a solar panel with battery to pump water thru gas water heater.the only power cost is the blower jets bubbles motor but you would only need to use that when you are in the hot tub(most power consumption is from running the element

Hi there, thanks for the video! How do you keep the temperature of the hottub at the right level? Is there an option for a thermostat in the portable gas boiler? I the video you suggest to use a timer that switches the system on for 2 or 3 times a day for half an hour. Is that enough to keep the water warm? Thanks for your help!

[@richardbodicoat6413]

When I had my lazyspa palm springs I used to leave it set at 40c 24/7 so it was ready to use as and when from April through to October. Obviously it's expensive but I want it to be available at all times without having to wait for it to warm up. To recover the money that the tub costs to run I eat cheaper foods like beans on toast and eggs on toast from April to October. The savings on my shopping pay for the total hot tub running cost with some change left over. My overall health also improves due to the reduction in calories from eating healthier foods that are less expensive to buy. I pack my hot tub away in October otherwise I become abnormally thin.

Hi mate great video. I'm currently setting up a system off grid and therefore using an lpg heating system for my tub. Ours is a rigid tub and I'm tapping into the pipes directly under the tub. My only slight query is where to put the pump? Is it on the pipe going to or from the heater? There's a pump internally on the tub and I was wondering if this would just suffice or whether I would need the additional one I've bought. In my head I keep thinking that the water will just be pushed up through the heater and out with the existing hot tub pump, but then I keep thinking I need one on the pipe going to the heater which presumably will push the water through the heater back to the tub?? I'm confused!

I did also use chlorine etc for my old above ground pool and would do now for the lay z spa. Appreciate any thoughts on this, Thanks

List of parts needed to do an LPG conversion. All available from Ebay. 18 L/min 36kw tankless water heater. High pressure 12 volt DC Diaphragm Pump 17L/min. DC 12V 5Amp 220V Power Supply. Commonly used for LED Strip Lights. 12V Mini Power Songle Relay SPDT 5-Pins Digital Time Delay Relay Trigger Cycle Timer Switch Display Board LPG gas bottle and regulator. Same type used for garden heaters. 2 hose pipe connectors and jubilee clips and hose pipe. The timer relay and 12 volt relay are used to reset the boiler every 15 minutes to override the 20 minute internal timer in the boiler. The internal timer turns the boiler off after 20 minutes and you have to reset it manually without the timer module. This conversion is for the boiler to be mounted outdoors and the hose pipes are put into the Spa water. My Spa is inside a Summerhouse. The LPG heater is also inside the summerhouse. The Boiler has to be adapted and a flue pipe added to be run indoors. You will need some thin copper sheet and Car exhaust repair paste to fully enclose the burn chamber and a few screws so that all of the gases exit the flue. Never run these Boilers indoors as standard. They give off carbon monoxide. You must fully enclose the burn chamber. It is simple to do. There are open vents at the top of the burn chamber. These need to be blocked off with the copper sheet and sealed with the exhaust repair paste. Screws hold the copper sheet in place until the paste sets hard. I have mounted the 12v DC power supply inside the Bestway Egg and removed the electric heater. My pipe connections to the Diaphragm Pump are made inside the Egg so that there are no hoses in the Spa. Doing this enables you to use the Egg inbuilt control buttons to switch the heater on and off and also control the temperature of the Spa water. You can still run the Egg circulating Pump independent of the heater and you can also continue to use the timer controls to heat up whilst you are out. Just switch on and wait for it to heat up. It switches off when the desired temperature is reached. Switching on the bubbles turns off the gas heater. Mine takes 45 minutes to heat from 19 degrees C to 36 degrees C and costs approx £1.50 in gas.

[@baldrickscunningplan6154]

Tried it. You get E02 errors because the flow is restricted too much. It also depends on the type of lpg heater that you use. Many are setup for mains water pressure. ie, it takes mains water pressure to open the gas valve in the heater to turn the heater on. I used an 18l/min lpg gas heater. The pump in the lazy spa Egg is not powerful enough to switch the gas heater on. There are some 240v pond pumps that will have enough pressure and flow but who wants to put 240v pumps in their lazy spa's? I modified the gas valve in the lpg heater to operate on lower water pressure and used a separate 12volt water diaphragm type pump. The pump is rated at 17litres/min and is commonly used in campervans and caravans. I removed the flow sensor and ceramic heater from the Egg.

Mr Meaner I’m assuming that is because it’s meant to be hooked up to some type of pressurized system, like hooking it into a hose outlet or the like which would push the water out and the 5l/min would be the most it could heat up. Since this is in a closed loop system it would need something to pump the water from the pool.

@@MichaelFlatman Technically you are right, bus alas electricity in the practice of an inflatable spa is not 100% efficient: if you have a spa like mine outside, on an average Dutch spring day with a temp of 15C, the spa loses 0.5 degree per hour, while the heater heats up 2C per hour, so effectively it heats 1.5c per hour. So if you want to heat up from 28C to 38C, it takes about 10 hours to heat the tub. The solution above, if I understand correctly, can heat a tub far faster. So in the end, it might be cheaper after all. I still use electricity, but we have our spa in a little garden shed, that help against the heat loss.

[@baldrickscunningplan6154]

@@AppCarpetCleaning It is quite a noisy pump but all diaphragm pumps are. You will not be able to generate enough pressure from a centrifugal type pump unless you use a 240volt pump of 800w or higher. I only wanted to use 12volt for obvious safety reasons. You will not find a 12 volt centrifugal pump that will generate enough pressure to operate the gas valve in the boiler. They are not powerful enough. Even the brushless ones are lacking enough power.

@@baldrickscunningplan6154 thank you. I’ve seen a number of different pumps used for different reasons. Still unsure which one will do the whole job that I want it to do.

Hi can you tell me if a 16kw 8 ltr per minute heater is big enough to do my 800 ltr hot tub please

[@tryityourself3870]

Mark Baxter I could tell you. I only have experience with this setup

[@Thismanisright]

Great idea although on the website it's another £125 for the stand

[@tryityourself3870]

I think that’s gone up! Lots of hot tub alternative heating during lockdown 🤣

[@GoogleGoogle-ef5pw]

Can you send me the search terms for the stand? I’m getting a different one but I’m not finding any joy finding a stand. It’s probably dead simple.... I’m also dead simple lol

what size water heater would i need for a 820 litre hot tub

[@tryityourself3870]

mark brown same as this one. My hot tub is 900 Ltrs Aprox

[@markbrown-ls3xo]

Scarebusdriver thank you - do you think a 10 litre per min would be ok or do you think its to powerful

[@tryityourself3870]

mark brown you’ll be fine with that. It has a 60ltr / min limit from memory

Hi, I want to pay you for advice on setting this up in my home. Do you have an email I could reach out to?

[@HuDz1966]

Hi, i have more or less the exact setup as you, do this sound right. For me i have to have the water on more or less as low as it can go and the heat on full. This for me gives a steady trickle of scalding water almost (too hot to touvh).

[@chambresdhotelamexicaine]

How many liters warm water per minute please?

[@tryityourself3870]

It’s capable of 12l per minute

[@Nick-cf6ji]

What kind of pump is that. How long can it run before it starts to over heat or can it run continuous on a hot day like a pool pump?

[@tryityourself3870]

Marcher pump. It’ll run all day but the heater has a 20 min safety shut off

@@baldrickscunningplan6154 do you have the make and model as the link isn’t working

[@baldrickscunningplan6154]

@@GoogleGoogle-ef5pw This is my second reply. Looks like youtube removed the first because i put a link to the one i bought off Ebay. The model number is FL40.Its a Chinese clone of an Obart FL40 pump. They are strong pumps but they are quite noisy and get hot with continuous use. I installed a 12 volt 80mm computer fan next to it to keep it cool and although that solved this. The noise of the pump became annoying. I had an idea to use a cheap 24 volt submersible pump and it works fine. Comments from other tubers said it couldn't be done but it can. If you would like to know how, i can show you how its done. What boiler are you using?

Just trying to see if I will use a hot tub long term.

[@baldrickscunningplan6154]

@@GoogleGoogle-ef5pw I have the same Boiler but mine is rated at 18l 36kw. Probably marketing BS. You will need a 37mbar LPG gas regulator for that Boiler. They have a 3 volt solenoid that opens the gas valve. If you go over the top with the regulator. The increased gas pressure stops the valve from opening. Its not a very strong solenoid. I modified my boiler by enclosing the burn chamber with copper sheet and car exhaust repair paste. It can now be used indoors. It will work fine with the FL40 pump. I have been experimenting with modifying the gas valve to run on a lower pressure pump. I have got it working on a small 24v DC circulation pump but i can only use the summer setting on the boiler. The winter setting opens a second burner but it causes the overtemp failsafe to cut off the boiler. I don't get any issues with the FL40 pump other than the noise. If you can mount the pump a bit further away. The noise won't be so much of an issue. Don't forget to add a small cooling fan next to the pump to keep it cool.

[@Micksimpson84]

Use the pump on the bestway jobby run copper pipe through an open fire pit (doubles as a lovely feature in the garden) burn pallet wood for free even cheaper :)

Have a 12l boiler and a draper submersible running on garden hose but boiler keeps cutting out once water is above 25degress. Pump still running. Have to switch boiler off and back on. The boiler then runs for a couple of minutes and then cuts out seems like it's overheating won't run at all on winter setting can you help please

Good idea but also a way to get carbon monoxide poisoning. Move it away from your gazebo

[@tryityourself3870]

RS-Mike these units are designed to be used outside in well ventilated areas. The instructions are very clear .A canopy presents no ventilation restrictions. Also note once heated the unit is off so no chance of exposure to harmful gasses when the tub is in use. I’d recommend this to anyone. Massive savings to be had in heating your hot tub.
