Hi! We are currently looking into the K-Star 5KW heater for our small 12 foot pool, but I've been finding some conflicting information on waterflow. We currently have a 1500 gph filtration pump (calculations say thats 25 gpm). Initially I was concerned whether this would be strong enough to trigger the heater. However when reviewing the manual for the heater, it has a spot where it states max waterflow at 8 gpm and higher would need a bypass. Does anyone have any information on this? I found it extremely odd as in another thread someone talked about ensuring a strong enough pump for this heater.
K-Star 5KW Electric Pool Heater: Pump Size??

- 16,964
- Pool Size
- 20000
- Surface
- Plaster
- Chlorine
- Salt Water Generator
- SWG Type
- Hayward Aqua Rite (T-15)
This shows 8 GPM max as well:
The fittings are quite small so I suspect that it is meant to have a bypass for any sort of normal operation. Otherwise, it would cause way too much head loss.

I would consider a Raypak, Coates, Hayward etc. over this model.

Where will the heater be located?
If outside, the heater has to be rated for outdoor use.
Check with the manufacturer to verify the installation instructions.
Do you have 240V, 30A circuit with a GFCB available at the equipment? That is needed for that heater that size. You also need what the Canadian Electric Code calls Leakage Current Collectors (essentially bonding connectors) that are sold separately.
The heater will provide approximately 17,500 BTU. Divide that by how many pounds of water you have (1 liter = 1kg X 2.2=pounds) to see the heat gain you can expect per hour.

Thanks James, I am going to check that out. We deffered buying a new heater until this year so just catching up on this thread.I would consider a Raypak, Coates, Hayward etc. over this model.

My husband is a certified master electrician with his own electrical company so thankfully we have that covered.
