Are they all basically the same? Our current one, 22 years old, has shit the bed.
Any inmates in the business in SW Riverside country?

Im not sure how they have changed in 20 years. But the pentair mellowyellow installed on our pool is crazy efficient and heats quick. Spa goes from 60 to 90 in no time
Another vote for Pentair equipment.

A 20 year old heater was maybe 70% efficient when new at best, over 20 years it may have been 50% at best before it died.
New heater is around 84% efficient.

I was in the same boat, I had a Hayward heater that was 23 years old and it finally died. I replaced it with a new Pentair heater. Now we use the hot tub twice as much as before and the gas bill is half of what it was. Much, much more efficient.

we typically do pentair equipment, but can do all
where at in riverside, and how soon you need done? One of my guys can do on the side
Murrieta, 15 and Clinton Keith.
No rush but if they want the work I'm open as soon as they are. Ball park $$$?

Something must be wrong with my 5 yr old pentair since everyone is talking about speed and efficiency with theirs. . Just took an hour to go from 53° to 83°. Still waiting to go in. We’ve calculated that it costs us $20-25 per night. Usually 4 hours or so.

Our spa is 6.5' in diameter and approximately 3.5' deep. With the new heater we can heat it from 50° to 100° in about 50-60 minutes. We figure it costs about $5-7 or so to sit in it.

We replaced our 20 something year old swimming pool heater with a Rheem unit (same as Raypak, I think) a few years ago. It heats our small 10k gallon pool very fast.

Only issue we had was intermittent failure of the ignition module to light the flame two summers ago. I beat on the internals with a rubber mallet and back on it came. No lip from that unit last summer, I think it got religion.😁

We have a Pentair electric pool heater. We use it only for our spa. Found that floating a cover on the spa speeds up and retains the heat when the spa is not is use. The 8’ dia plastic over came from Amazon. It‘s basically heavy duty bubble wrap. Heater works well and the bubble wrap really helps. Pentair pool heater was here when we bought our home in 2013. Realize it could take a dump tomorrow. Over T’giving our visiting NYC SIL thought it wasn’t quite warm enough for him. So he cranked the analog knob up, without me knowing it. Didn’t take long for those of us in the spa to start saying WTF? This is getting Hot! Daughter and grandson even dove into the very cold, non heated, big pool (15 x 30). When I put a manual thermo in the spa, temp was 110 and climbing! Crazy hot. So, we all got out. Thought the pool heater thermo had messed up. It was then the SIL spoke up and said he’d “dialed up“ the temp (without knowing WTF he was doing). About 102 for the spa seems good for us, winter or summer.

We went from a 22 yr old pentair 400
To This about 2-3 years ago.
So much more efficient and heats ours up very quick.

Raypak has been around for ever. For residential and commercial.
on a heater only install, theyre all pretty similar. pentair and starite are identical same manufacture just different cabinets, thye have a spiral type exchanger makes them more efficient. Hayward and Laare now have similar option, also helps minimize footprint

as far as heating, on a 7ft spa should avg 1 deg per minute. So from 53 deg to 100 should be 47 mins give or take
air and ground temps play a small role in this.
also heat mode - pump speed should be 2600rpm range or lower. The slower the water gets thru exchanger the higher the heat rise
if spa mode is set at 3450 rpm it will actually take longer, to fast thru exchanger plus if thru jets aerating water with cold air temps will lower the avg heat rise.

Price avg 3600-4000 depending on what’s needed for install

OK, I'm ready for your wizardary math.

We're going to heat our new pool for the first time for a New Years Party. 17K Gallons, 400BTU Pentair Natural Gas heater, and current water temp is 50 degrees.

How long do you think it's going to take to get the pool up to around 80 degrees?

General rule on pools is 1 deg per hour ( smaller pool may get 1 deg per 35-45 mins )
so in theory would take 30 hours of heating, reality on a 17k gal pool likely 2 days running 12 hours per day should get ya there
if natural gas costs about 8.00 per hour for 400k btu x 30 = cost would be roughly 240 to get it there, plus how ever many days your trying to maintain that temp.
propane costs and certain nat gas area costs can differ drastically higher

Awesome, so since this is new experience for me, my pool currently runs 8hrs a day, 8am-4pm.

Should I switch up my filter time, so it runs for 12 or more?, and only heat during those hours? You think I should run it at night, or during the day, I don't want to loose all my heat that I put into it overnight??

I'm not sure what our NG cost is, but you're probably close. I'm not on Propane. My rough guess was get it hot by NYE, enjoy it for the night, turn it off at midnight, and hope it didn't cost more than like $600 for the party.

You should probably look into a pool cover and or those heat absorbing things you put in the pool if you have good sunlight hitting it.

Natural Chemistry makes a liquid you pour in that’s called cover free. It’s a liquid solar blanket. Will help retain heat. Turn heater on 3 days before add liquid cover and retain good part of the heat.
