I have a homemade coil pool heater made with 1200 feet of half inch black irrigation hose that I have been pushing water through with a Hayward 1 1/2 HP pump and sand filter with a TEE at the return side of the filter. This is a 24ft. hard sided 52" round pool and I have 6 200 foot coils on an eight by twelve foot table about the same height as the pool so normally I have to run the pool pump and filter to heat the pool which is very expensive to run all summer. I purchased this little pump on a whim to see if it could push through the coils at all. Hooked it up and I was very surprised! Output is only about 1/2 the rated flow, but it should be fast enough to keep the coils from overheating and it's constant with good pressure behind it. Priming was not a problem as the input water line is about 10 inches below the water level of the pool. From the reviews I've read, It would be wise to get a backup just to be sure. This pump has only been hooked up for about an hour, so I will be updating this review as time goes on. UPDATE 05/27/21: 1st week in service, the little pump presses on. I was a little worried about the water temp in the coils as we had an 85 degree day, but the pump was able to move the water fast enough to keep it from boiling. Peak temp coming from the coils was only 104 degrees. No problems with the little pump. It takes about 12 minutes for this pump to make a trip through the coils while the filter pump was only taking about 9 minutes. Opening day is this weekend (Memorial Day) so it will be put to the test with even higher daily temps. 1 MONTH UPDATE 06/16/21 Still chuggin'! We had record high temps the past week and I clocked the temp of the water coming into the pool at about 140F. Almost 4 weeks in and the only difference is that the pump seems to be operating a little warm, but that could be due to the higher ambient temps this week. Pool temp is 94F and climbing each day. At these higher pool temps, we swim at night. I like to let the pool heat up as much as it wants and as the daily temps come down at the end of the season or we have cloudy days, which will happen, the extra heat will be appreciated. If we have pool events like the 4th of July, I will put a tarp over the coils to cool it down a bit for that if need be. Further updates to come if needed. Fathers Day The pool was a balmy 95F when the whole family got in. With 10-12 people in the pool, I ran the regular pump and filter. The little pump has allowed pressure from the pool pump to continue through itself when not needed. Prior day mishap: On Saturday as the little pump was doing its thing, between 2:00 and 3:30 PM, the hose from the inlet side of the pump where it connects to the pool plumbing got so hot from the near 100F outside temperature that the hose slipped off of the pool connection which left the little pump running but not pushing any water through the heater and pool water pouring onto the ground next to the pool. By the time I caught it, the pool had lost 3/4" of water and the heater coils were very near the boiling point. Quickly, I re-attached the line and turned on the pool filter which began pushing water through the coils again. I lifted the hot water inlet out of the pool to verify flow and could not believe how much steam (vapor) was coming off of the water out of the hose which was nearly impossible to hold on to for more than a few seconds at a time. Once the water cooled back down to NORMAL, I again allowed the little pump to take over on its own (good little pump!). So, even after having to pump dry, the little pump came back kickin'. 05/02/22 We sold our house with the pool and the little pump was still chugging away when we left. We are getting a new pool and will be buying another little pump for this pool at the new house. 04/11/24 As I stated in my last update, we moved. Came to New Mexico and put up a new pool. I bought a new "little pump" so it was ready to go when the pool and coils were ready. Come to find out that I didn't need the coils at all! The mid day heat from the sun was enough to heat the pool to over 104 (that's as hot as our hot tub gets) so I had no need to put in a pool heater. The new little pump has a new job now, supplying water to a water feature in the back yard and it's doing great! The new owners of the old house (in SLC, UT.) did not keep in touch so I have no news on the pumps latest feats, but I'm sure it is doing well.

Great little brew pump. I mainly use this pump to recirculate hot ~180F water on the hot side of my heat exchanger for controlling mash temperature while recirculating mash water through the other side of the heat exchanger. I have another version of this pump recirculating the wort through the other side of the heat exchanger. I have this one powered by an InkBird temperature controller when controlling mash temperature and powered by a switched outlet when pumping water up to my Hot Liquor Tank. The only issue I have with these pumps is that even with the pumps below their water sources, they still require a little effort to prime. I have to flow water from a pressurized source through the piping system system to ensure it is full or the pump takes a very long time to clear even a small amount of air trapped in the suction line. This can be quite challenging when you forget to fill the suction line prior to heating up the water source. I also have my piping system set up so that this pump can supply my hot sparge water to my Hot Liquor Tank. When testing this pump I found that while flowing through ~8ft of 1/2" ID piping, a few valves and raising the hot water ~7ft to fill the Hot Liquor Tank the flow rate was ~2.1 gpm. So if you are looking for an inexpensive pump that can handle hot liquids and has a good flow rate for recirculating home brew, this is a very good option. I have only used this pump for 2 brew days so I can't speak to its durability, but so far it is doing exactly what I had hoped. I have also found no issues with its performance while throttling the flow (2.1gpm is more than I want for both mash recirculation and sparging.

I purchased the bayite BYT‑7A015 12V DC circulation pump to help with recirculating mead while brewing beer, and it has worked better than expected for this purpose. I wasn’t looking for something industrial—just a reliable, quiet, low‑flow pump that could keep liquids moving gently during brewing and temperature control stages. This pump has been a solid match for that need. Pros -Very quiet operation – barely noticeable while running, which is great during long brewing sessions Smooth, consistent flow – the 8 LPM (2.1 GPM) flow rate is ideal for recirculating mead or wort without excessive agitation -Low power & efficient – the 12V DC operation runs easily off the included power adapter -Compact and easy to install – fits well in tight brewing or fermentation setups -Runs cool and steady – no overheating issues during extended operation Cons -Not self-priming – needs to be filled with liquid before starting (fairly common for pumps like this) -Plastic construction – perfectly fine for brewing, but not meant for high-pressure or heavy-duty applications -Limited head height (3m) – works great for recirculation, but not for pumping long vertical distances Things to Consider Before Buying This pump is best suited for recirculation, not rapid transfer or large-scale pumping Make sure your system allows for gravity-fed priming Ideal for homebrewers, mead makers, and DIY setups—not commercial operations Reasons to Buy Excellent choice for recirculating mead, beer wort, or temperature-controlled loops Quiet, stable, and gentle flow that won’t disturb your brew Simple setup and dependable performance Very good value for the price, and you can often find a better price on Amazon compared to other retailers Final Thoughts Overall, the bayite BYT‑7A015 has proven to be a reliable and practical pump for my homebrewing needs. If you’re looking for a low-noise, low-flow circulation pump specifically for brewing or fermentation recirculation, this is a solid option that does exactly what it’s supposed to do. — Reviewed after real homebrewing use
