Ref Hayward 11 kw CSPA - how long will it take to heat a spa of 600 gals from 70 degrees to 100 degrees?

don't really know. We flip our heater on and get in about 2 hours later.....its near 100. Not sure starting temp.

I believe it's rated for 480,000 btu, so it would be 93,000 btu/gallon...so a little over 5 gallons an hour if it's on 100% of the time. Heating our hot tub it takes about 20 minutes to bring it to temp of 101, then it cycles on and off.

At 6 feet above sea level with cold water standing at 73 degrees, it takes exactly seven minutes to heat water up to 212 degrees at max fill line.

I have only used Vulcan 116 on my in-ground pool and it doesn't get any where near that hot. Sorry, I don't have the answer, but I've been on the Tremco website https://www.tremcosealants.com/ and they can answer your question.

The heater has a setting for pools that goes up to 90° I believe. It also has a setting for spas I'm not sure How high it goes because I only use the heater for my pool. I don't believe you could separate the two functions out and heat both the pool and spa at the same time.

It heats to 104, which is very hot. We are just coming into colder weather with our tub, and it suppose to only run for 8 hours at a time. We turn it on when we go to bed, turn it off when we get up, and give it a couple hours rest. That way it doesn't get any lower than 80 degrees, we use it at least once a day if not more, and don't want to wait too long to get to a hot temp in the colder weather.

Short answer: It isn't big enough to go deep into the tank, (note the max water depth), but maybe, if the tank doesn't lose heat quickly it would take around 2 hours. Longer answer: Depending on how hot you want the bath to be, it might work. This heater theoretically generates (watts) * 3.412 = BTUs/hour ==&gt; 1150 * 3.412 = 3923.8 BTUs/hour. Say you want to heat that to 115 from 45 degrees, you need to heat the water 70 degrees. Each gallon takes 8.34 BTUs to heat 1 degree. So in order to heat 100 gallons 70 degrees, you'd need to generate 7000 BTUs. If I've done my math right then the last thing to do here is figure out how much time it would take. 7000 BTUs / 3923.8 BTUs/h = 1.78 hours or 1 hour, 47 minutes. However, the tank will lose some heat over this time, depending on losses through the bottom, sides, and evaporation, it may take longer.

Not sure of the btu's but it heats my 500 gallon hot tub from 55 to 104 in about 3 hours

No, 104 is the max. Recommended temp for hot tubs generally is 100-104, and this tub achieves a good, hot temp. (It takes several hours to initially achieve the max temp but holds it pretty well thereafter.) Highly recommended.

I used a heat gun on low setting of 750watt, worked just fine, just be careful not to get too close, it can melt it.

I live in the mountains of Idaho at 6,000 feet with cold and snowy winters. My 110 volt holds at 104 until you get in and take off the cover. After about 45 minutes it drops to 100 to 101. Good economical hot tub.

About 1.8-2.2 amps @ 12V 600 gph pump. The bigger questions is for how long? Mine lasted a whopping 30 days before burning out. I would recommend a Rule or Attwood pump instead. I have some 17 year old 2000gph Rules that work just peachy and I use an Attwood Auto 800 in my shower sump which gets used almost daily. The Attwood can be cleaned easier in hair/fouling applications.

It's the amount of power the unit has. The more power you have the faster you heat. I have a 400 and it heats my hot tub in about an hour.

15 Amps at 110 Volts AC is 1,650 Watts. That would be the absolute most it could handle. If your pool pump is over 1500 Watts you may be better off with a larger timer (in case of voltage spikes and sags). If your pool pump is less than 1000 Watts it should run for years (mine has).

This model turns on the heater when water flows and adds 3500w of energy to whatever the incoming water temperature is. At 0.5 gpm the water temperature will rise about 45 deg, so if you begin with 60F you'll get 105F, but when the 120F water arrives it will jump to 165F.

I m am heating a well insulated area approx. 12' x 12' and its the only source of heat. its always around 70 deg. and the thermostat is set at 2. I highly recommend this heater. I use natural gas. if there is a power failure it will continue to operate. I shut it down in the warm months and restaI heat an area 12' x 12' and its my only source of heat on that side of the house. I converted an attached garage into a bathroom and laundry room. with the thermostat set at no. 2 its always 70 deg. its running on natural gas. I am very satisfied with its operation and it will fully operate with loss of power. i rate it highly and easy to install I m am heating a well insulated area approx. 12' x 12' and its the only source of heat. its always around 70 deg. and the thermostat is set at 2.
