Very well! Still using the pool 12 months a year, though some months only had 1 sequence of hottubed evenings (3 day weekends) instead of 2. Gas bills are rising but still only $100-200 extra for the pool’s share. Thanks to combo or foam blanket cover and judicious weekends (4 day contiguous...

Only seeing this now. It is 2021. TThe plastic-sheeted foam pool cover is holding up well. I’d wager 3x longer lasting than solar pool cover. It’s on its third year and looks like it will last another 6-7 years before I need to replace it. It is WAY more puncture resistant than the old...

Nice! I need to obtain sensor monitoring. [googled that thing] Ambient Weather model # WS-8482-X3 correct? Only ~$85 including a few wireless temperature sensors!?! (And I can add several more later - soil temp sensor, water temp sensor, air temp sensor) That's really cheap for...

Yes.. It's called Blue Shield Poly which is located near Barrie, Ontario, Canada. Cost me about 4x to 5x as much as the bubblewrap type (that fell apart in only 2 years). It has a 6 year warranty. They sent me a free sample 1.5 years ago, which I kept until my bubblewrap cover...

Variable Speed Pump Made a Bigger Than Expected Bill Cut Also another new observation. After installing the Tristar VS Pump variable speed pump in 2016 to replace that old pig (oink, oink) of a 1.5 kilowatt fixed-speed pool pump. That one move practically chopped our electricity bill in...

New Foam Pool Cover Been a while, but I have a new upgrade: A foam pool cover. Basically, 3 millimeter thick laminated foam pool cover. Cost me 6x the cost of a common bubblewrap pool cover but has a 6 year warranty and hopefully pays off in lower gas costs after just two seasons or so...

I'm researching options of double covering; I suspect I would get away with two rollers with a combination of: - 1/8" foam cover (there's a variety of brands) - "Mesh Pool Cover" with no straps but has grommets (18'x36' to overlap a 16'x32' pool) and attach it to a longer roller. ......To...

Ouch -- I just checked rates -- On January 1st, 2017: My rates rose from 11¢/m³ to around 16¢/m³ before taxes !!! !!! (rate rise + cap-n-trade started up). So my rates might have just become slightly more expensive than yours. I may have to revise my bill estimate (to $400-$550 territory...

Hello! I'm researching available foam covers for a rectangular 20,000 gallon pool. They're brands sold in Australia and USA, but there's none locally where I live (Hamilton, ON, Canada) and they are expensive. Are any of you using a foam cover? ...~1/8 to 1/4 thickness (approx, give or...

I measured my pool just before leaving work (I haven't touched the covered pool since Sunday night after .... whole system is on autopilot using the pump timer, 4h:20h heat:trickle cycle, and it was rechlorinated to 5ppm). Current temp of pool is 79F as of Friday morning. I did not override...

That said, when covered, that eliminates most of the "70%" (percentages vary on variables and setup, but let's use the, for simplicity) When covered is solved, the "20%" radiant loss and "10%" pipe loss.... becomes the major remaining factors. Relatively speaking, 20%:10% ratio means...

I plan to get a temperature logger to monitor heating rates and cooldown rates. (...Wouldn't it be fantastic if I can export it to Excel and see graphs of heat-up and cool-down curves...) You said you have a 2 speed pump, rather than a variable-rate pump? I presume you use the low speed when...

I'm doing some thermodynamical calculations since I am naturally curious. So in a snowstorm you lose 4F in 12 hours. What was the air temperature at the time? Was it with dome only, or with both dome, and pool cover? Note about measuring temp: - Dip thermometer is more direct measurement...

It varies a lot. A few hours a week. Long answer: In our photos, you can see that there is a fair bit of foilage surrounding our pool. It consists of 1/4 to 1/2 of our pool maintenance overhead (debris that needs to be saept off cover, vaccuumed from bottom, and skimmed with net from top)...

Either way, thanks for the info on the dome blower! It may not sway community concern and the pros of open sky may outweigh, as long as the pool can get double-covered when not in use somehow.

Another unexpected benefit I got with the Hayward Tristar VS that I got, is that I can now more easily run the pool in freezing weather without needing to shut down/winterize. There are super slow speed settings (like 1/25th to 1/50th horsepower) at a mere few watts at 600-800rpm to trickle the...

New tip: Decorative laser projectors are wicked cool with steam rising from a hot tub -- especially a pool sized one. The lasers, normally not visible in air, becomes very visible in the steam. You can buy these laser projectors for about $20-$30 at many places (the cheaper "AS SEEN ON...

1. Full speed pump when heating. Better heating efficiency. 2. Continuous run overnight (make sure heater has BOTH overpressure/overtemp safeties). 3. Heater set to maximum temperature (or slightly above target temp) 4. Pool always covered up. Only uncover whenever swimming. 5. Pump OFF or...

BTW..... Water resistant battery powered app-color-programmable Christmas Lights unreeled while I am inside the pool! The string is a USB plug but the rest is IP65-rated and perfectly fine for the pool edge at low 5 volts. Just get a USB power bank (portable USB battery used to charge...

We are still running the pool through the recent snowstorms and figuring out best double-cover operations. I think we are trying to figure out what has best efficiencies (e.g. 1750 RPM at 200W electricity but less natgas heating efficiency, versus 3200 RPM at 1000W electricity but better natgas...

I live in Hamilton, Canada and we are planning to skip closing the pool at some point with some tricks we have learned running our pool so late (Dec) and reopening so early in the season (March)

We opted to keep the pool heater route, not the boiler. -- Raypak Digital 266 is installed. -- Tristar VS Pump is installed. Took a lot longer than expected, being without the pool for over 2 months, so it's good to swim again. Poolside snowman time! December 11th, 2016 Temperature of 95F...

I spent some time doing some math on pool heating. The pool is 20,000 gallon, so it requires 166,000 BTU to raise it 1F We've been able to achieve between 1.5F-2F/hour when heating 35F to 55F and about 1F/hour when heating 75F to 95F. I am now asking about upsizing the boiler, to ensure we...

Final decision not yet made, nor the model. Still inviting more feedback! (While I get some more real-world referrals)

There are multiple models, but the Navien NCB240E (not the "tankless heater" model NPE240, but the more all-purpose boiler NCB240 boiler; they seem to have better reviews and more appropriate for our case) -- runs at $2500-ish, without the labour and extra primary loop components yet factored in...

Thanks for the tips to add to research and decision; Corrosion: Pool water doesn't enters the boiler -- only into a cheaply-replaced, insulated, external exchanger between 160F primary loop, using off-the-shelf components. As the boiler is protected from pool water, this can give me more...

(2) Heater plan change! Since I told installer I need poolhouse heating and a hot shower too. "...why not use a boiler instead of a pool heater?" Navien ncb240e boiler. One machine to do all three, pool heat, poolhouse heat, shower heat. Thread: Boiler instead of a pool heater?

The machine the pool heater installer recommended is the Navien NC240E general-purpose boiler. It is not just a lowly or cheap "tankless water heater" but a real bona-fide general purpose boiler too. He also does Hayward and Raypaks too, but installs boilers too, including for pool heating...

Update!!! (1) Electric Panel is now installed, 240V ready. Photos here: [Canada Code] Sharing 240V And 120V Appliance On Same Circuit In Workshop Shed? - Electrical - DIY Chatroom Home Improvement Forum
