What Size Heater do you need for your pool, spa or hot tub?

[@frankdontsurf]

I have a small above ground pool, 4800 liters. I would like to keep it running around 28C but the ambient temp here is usually 32C down to 21C for a few weeks out of the year. The idea is to just beat the cold those winter weeks. Would you have any recommendations that aren’t the DIY for my situation? Thanks.

I want to do a hottub with a 1000L tote, what setup would you recommend? Electric Heater and pump. Thanks

Hi There, sorry for late reply - 3KW electric spa pack, BP7 or BP8 depending where you are - 0.33HP for circulation - plus a separate pump (of a dual speed) if you are doing jets. Hope that helps - Andi

I'd like my pool to be about 95 degrees for a 25k gal in ground pool. We're in Fremont CA and have an old electric panel. What should I get? Mostly weekends

With your climate, go for an Air Source Heat Pump - worth the investment - shop.buildahottub.com/product-category/air-source-heat-pumps/ - hope that helps - Andi

Can an electric heater heat a 1000 gallon hot tub?

[@Buildahottub]

Yes, would just be slow - you can see on here how long it would take - buildahottub.com/heater-size-for-your-pool-or-hot-tub/

Where is the size chart?
