is this unit for above ground or inground and how many BTUs are necessary for 18' x 30' pool?

Inground. The 250,000 BTU I bought heats my 9 x 30 pool in Palm Springs quickly (about 2 to 3 degrees an hour with air temp of 75 degrees) and at about 30% less cost than 14 year old heater it replaced. I would guess you would need at least a 400,000 BTU for your pool to get the same performance. A 250 may work but it would have to run much longer than a larger heater. If you go Haywards web site I'd be surprised if they didn't have a calculator that would tell you exactly which of their products would work best on your size of pool.

Yes! This heater is large enough for even a larger pool than that. 400000 btu's simply means it heats faster! Watch out during the winter months gas bill will increase largely if your pool and pool lines are not insulated. Do your research!

Lines have brass flare connectors. BTUs is rated with 16' line set. Drop is very insignificant when extended. Unit comes precharged (entirely charges to outdoor unit as shipped).

I use mine for a 24 ft round above ground pool. 14000 gallons. I think it would do just as good on a 33 ft round pool. 20 something gallons. If you are considering using this on an inground pool, I would definately consult a pool specialist. If your inground pool was just a plain Jane type of pool , sure this would be fine, but on todays inticate below ground pipeing, itvmight nto be able to hqndle it or you would have to improvise on pipeing connections. Talk to your local pool outlet stores and ask them also.

Hello You have to contact the customer service to let them know that you want one 18000 and two 9000 btu inside units, be careful my outside unit broke down after a couple of months, I had to call them several times after many calls they didn't want to take my calls, they sent the spare part after 6 months so it's up to you I don't recommend this company regards

Pool heaters are sized by the surface area of a pool, not gallons. Assuming you have a typical 16 x 32 in ground pool, which is about 20,000 gallons, you would need a 200,000BTU Heater. Go here for an exact answer http://www.haywardnet.com/pdfs/Heater_Selection_Guide.pdf

Cannot answer the BTU maximum, but have been using for one year with a 440,000 BTU natural gas pool heater with no problems.

4600 BTU 250 sqft heating area, I'm assuming this is with everything set a maximum

The 60000 btu would work great. It is over sized but for the priceit is worth it. I have 750 sq ft garage with 12ft ceiling and it heats it up fast. Less strain on the unit.

I would not recommend this for anything except an above ground. An inground pool requires much more plumbing and the pressure has to travel a farther distance I do not think it would suffice.

Above Ground Use Only. Inground Filter Systems are entirely different due to pvc piping configurations for their own individual pools.

Not at all. As a matter of fact this system will clean a above ground pool 15 x 48 very well. I have a 15 x 48 and love this system. This system will clean this size pool, but any pool bigger than this needs a larger filter sysyem. Hope this helps. Sheri G.

I have an 18ft above ground pool, which is about 8000 gallons. It seems to heat my pool about 1-2 degrees per hour. In October the pool got down to 55 F, I would run the heater on Friday from about 9am - 9pm and it would get up to 74 F, then on Saturday the pool would be back down to 70 F and I'd run the heater again and get it up to a toasty 80+F. I did also get the conversion kit and ran this via natural gas and not propane.

Solar panels produce anywhere from 1000 to 2500 BTU's per square foot, per day depending on your climate, (northern, southern, mid). These panels are rated at 2 square feet, so 2000 to 5000 BTU's per day, depending on location. 1 BTU will heat one pound of water by 1 degree fahrenheit. A gallon of water weighs 8.33 lbs, so you would need 8 BTU's to heat 1 lb of 70 deg F water to 71 deg F. The water in your pool weighs 19,800 pounds. Just to raise the temperature of your pool water by 1 degree you would need at most 9 panels, or at minimum 4 panels. From your question it looks like you want to raise the temperature of your pool water from ambient 68(70) to 89(90)? That is a 20 degree delta T, so realistically you are looking at a 396,008(400,000) BTU load to keep your pool at 90 degrees during the summer,(which to me sounds wayyyyyy too hot for a pool). At best, producing 5000 BTU's per day from each solar panel you would need 80 of these panels to maintain temp. If you wanted your desire temp to be 80 deg F instead of 90 deg F than you would need 40. Someone correct me if I'm wrong. There are pool specific solar panels that might produce more BTU's per square foot of usable solar area. In my opinion, 80, or even 40 of these solar panels sounds a little unfeasible. Yes, you could do it, and it might be cheaper than purchasing a 400,000-500,000 BTU gas fired pool heater, but realistically it's not a good application for these specific panels. The common solar panel size to heat water for domestic hot water in households is an 8x4 which they rate for 40,000 BTU's. For those you would only need 10, but again might be a bad option, as they are large, and are quite expensive given their size, (usually 800-1400$/each). Hope this helps. PS. I am also not a pool expert. I am not sure on the thermal retention that pool water holds during the night. It could drop 1 degree in 10 hours or it could drop 10 degrees in 10 hours, I really don't know.

I have 832 sq ft on a the 1st level and 512 sq ft upstairs in a well insulated outbuilding (Michigan). My unit is 60,000 BTU, in my 2nd winter and doing fine.

We have a 27'×4' round above ground pool and this pump works just fine with it. Hope this helps.

I purchased a 9' x 18' retangular pool. You wil need to add 2' to each side minimum. I purchase a screen cover for my pool. It keeps all the insects and trash out. That is the key to low maintance.

I would believe this is 13000 BTU. I have the unit and it cools my 20' x20' room. I would not count on more than that for this unit.
