Heaters

Hello,

We have an Intex 18ft x 48in above ground pool salt water pool. We purchased a solar heater which worked quite well in the heat of summer but we are looking at an additional heater. We live in Minnesota and would like to extend the use just a bit. We are looking at electric or propane - tankless. Any suggestions, size recommendations? My bf is looking at an Ecosmart 27kw, 240 volt, 112,5 amp for about $560. They are much more expensive than I thought!! :)

Thanks everyone!!

Stay away from home tankless water heaters, they are not designed for the flow rates and run times that a pool pump would provide.

If you want a heater for your pool, get a heater designed for a pool.
 
It may be for a pool but the electrical requirements for that heater are a little bit nuts. It need 3 independent 220v 40amp circuits. It will consume 112 amps of power continuously. That is a massive amount of power for a residential installation. That's going to make your lights dim when it switches on. Does your house have a 200amp service from the utility? If not you wont even be able to run the thing.

A heater like that is not the way I would go but I don't like astronomical electric utility bills.

Your signature says you have solar heat, are you using a solar cover as well?

That is very helpful! Thank you! Yes we do have a solar cover and solar heater. The solar heating systems works great but just not enough for Minnesota. What are your thoughts on a propane heater?

Maytronics Solara Solar Pool Heating System - is what we have.

 
Can you add more solar panels? its cheaper to run and cheaper to buy.

I hate the idea of burning propane for pool heat from a cost perspective. Other than that sure you could get a small propane heater for your pool. Between buying the heater and running the gas line, assuming you already have a tank, it's going to cost somewhere around 2000.
 
I like the heater that is listed in my signature. It cost over a grand but it does the job. I bought it so that we could swim even when the solar was not effective. Then, I learned some things. The kids don't want to swim much beyond June (We often start in Jan/Feb( so no need to extend. Also, even if the pool is warm, if it's cooler than 75, they freeze when they get out and don't want to swim.

So, I only use the heater at the beginning of the season when the temp doesn't want to get above 78. I use the heater to boost it to 84 and that's it. I let the solar take over from there.

You're in Minnesota. Are you sure a heater is going to get you a longer swim season and be worth the expense. Remember, the lower the BTU (cheaper heater), the longer it's going to take to heat the water, the more propane or electricity you're going to use. There is a Hayward heater that is less than $1000 but it is a low BTU unit.
