Swimming Pool Heaters

Information On Solar & Electric Swimming Pool Heaters. Pool Solar Heaters Info. & Savings Chart.

Swimming pool heaters will allow you to s-t-r-e-t-c-h your swimming season out just a little further.

It could also be viewed as an investment and may increase the value of your pool should you choose to ever sell your home.

Many parts of the country don’t have the right combination of water and air temperatures to make swimming comfortable early or later in the season.

If you’re thinking of a couple more months of swimming, you may want to consider a good pool heater.

The most popular models are electric and solar. However, a good swimming pool heat pump heater rounds it out nicely.

So, while your neighbors are sitting by the fire in their living rooms, they may hear, faintly in the distance, your children just finishing up their last back-flips and cannonballs of the day. 

Remember to keep your pool calcium hardness between 150 - 250ppm the best you can. Higher CH readings can calcify and possibly burn up the heater.

Inground & Above Ground Swimming Pool Heaters

Both inground and above ground pool heaters should maintain the desired temperature in most weather conditions.

A highly effective and efficient inground and above ground swimming pool heater could be mounted in either in a horizontal or vertical position.

It can be installed in new construction or in an existing filtration system.

Just set the thermostat and you’re ready to go.

Solar & Electric Pool Heater Installation & Questions

When you’re seriously looking around at the many ones available, you should keep a few things in mind:

  • What's the price? Is that the best you can do? There are others out there I like.
  • Out the door installation cost?
  • Does it have an automatic control? Automatic shut-off?
  • Any special plumbing required?
  • Is it rust and corrosion resistant? Show me why.
  • Will it install easily into my existing pipes and/or plumbing?
  • Are there any vents?
  • How large are the panels and how much room will they take up? Is it a compact design that would should fit my pool?
  • No condensation or corrosion, right?
  • Is it UL recognized?
  • Does it have a good thermostat? Is the thermostat automated?
  • Is there maintenance? If so, what and why? Will you take care of that or do I?
  • Digital control panel?
  • What's the warranty? I need to see specifics.
  • What if I install it? Will that void the warranty? I want that in writing.
  • Do you have a contractor? Is he licensed and insured? Is he experienced in these kinds of heaters? I need to see proof.
  • What are the safety features? What would happen if one of the safety features fail? If it does fail, who is responsible?
  • So you install it or do you have someone else? Contract it out? Who do you use? Why do you use them? Are they experienced?
  • If it does fail, who will fix it? Will you, or do you contract that out to someone else? Who is it? Why do you use them?
  • How about free delivery? I want that in writing.

Ask these questions to anyone trying to sell you a swimming pool heater. Be sure to get specifics and everything in writing. Whatever anyone tells you they can also put it in writing. If it's not in writing it didn't happen.
