    heating schedule

    Hi
    assume
    Western WA summer time temps maybe 65 daytime and 55 nighttime
    would like pool at 85
    would like to not run heater/pump 24/7
    and
    acknowledge will need to experiment with the schedule

    what would be a good heating / pump schedule to start with?

    thank you

    Re: heating schedule

    Even with a solar cover, that will be a full time heating schedule. You are asking the pool to be 25 degrees in excess of where it would normally be. There'll be some good engineers along to help with the math but I can tell you someone will likely need a second job.

    How big is your heater?

    Re: heating schedule

    Heater goes on at the same time pump goes on and use solar blanket to keep heat in during the cool evenings. Any temperature loss at night will be made up when pump kicks as heater will also kick on.

    True
    At the moment am trying the ComPool set to pump/heat 5am to 8pm with temp set to 85

    but was wondering if there is a more clever schedule
    by the way was 82 6am this morning so appears to have lost 3 or 4 overnight

    Re: heating schedule

    With oil as the source of heat, the time of day you run the heater only makes a tiny difference. Obviously you want the heater running for at least a few hours before you swim, to insure the pool is up to temperature, but otherwise the only constraint is that there be enough total runtime each day for the heater to be able to keep up.

    Using a solar cover, especially at night, will help a great deal.

    If there was a heat pump involved, choosing the correct time of day to run the heater would make a large difference.

    solar cover? if temp is 85 at 8pm and I put on a solar cover, what would you estimate temp would be at 5am?

    heat pump? no heat pump, still using the old equipment that was here when we bought the place in 2011 save for new pump, ComPool and glass in the filter

    thank you

    A solar cover will eliminate most of your overnight heat loss, and cut your heating bill significantly.

    Does that boiler provide heat for your house as well?

    sorry, should have mentioned
    there is another Burnham V7 boiler for the house; just as old but still working

    Re: heating schedule

    Got it. So it seems your setup is virtually complete. All you have to do is turn it on and judge your fuel consumption, is that right?

    Give it a try but I believe you will find the expense excessive.......monumental without a solar blanket.

    I am not familiar with boiler terminology but if it burns 2 gal per hour (per the specs on the plate), That would be maybe 80 gallons to get it to temp and then I would guess (and it is a complete guess) maybe 15-20 per day even with a solar blanket.

    Re: heating schedule

    So then
    heating experiments done with current old equipment (in the sig below)

    assume Western WA temps (hi say 65 lo say 55)
    assume ambient water temp about 65
    assume temp goal is 85
    assume current oil price $2.75

    experiment #1 warm up
    to heat up from 65 to 85
    about 34 hours
    about 50 gal fuel oil
    about $138

    experiment #2 maintain 85
    run pump/heater 5am to 8pm
    but found temp down to 82 in the morning and took all morning to reach 85
    not good for small persons so cost irrelevant

    experiment #3 maintain 85
    run pump/heater continuously
    about 14 gal oil in 24 hours
    about $40 per day

    but I read on the web that circulation at night actually cools the pool
    not good if trying to heat so

    experiment #4 maintain 85
    run pump/heater at 6-11am 1-5pm 8-9pm 12-1am and 4-5am
    did maintain temp at 85
    about 10 gal in 24 hours
    about $28 per day

    so would appear with this system tis $28 per day
    until warmer in July Aug
    until climate change raises WA State temps
    until I get different equipment
    or your clever idea here

    now if one says swim time in WA State is Jun-Aug or 90 days
    that is 90 * $28 or $2500
