Swim Season begins with Cool Temps


We went out with friends last night and the husband wanted to know about pool heaters.  He mentioned that this time last year they were swimming, but now it was too cold.  Yes, it is a bit cool for us as March draws to a close, but we still have clients who are swimming I said.  I won’t bore you with all the details but the message is the same- Heat Pumps or solar for the pool, gas heat for spas, and as an emergency backup to pool heat if you absolutely have to swim. 

When you look at heaters make sure you focus on COP- Coefficient of Performance.  COP says that if you put a dollar worth of energy into your heater you get $1 times the unit’s COP of energy turned into heat out of the heater for your pool. 

The best Heat Pumps have COPs close to 5 and some approach 6, and the very best gas heaters are in the .95 range with most around .78- there are minimum COP ratings required under the Florida Energy Code.  Of course all heaters do better if the pool is covered at night when most heat leaves the water.  If you just can’t live with the ugliness, storage or safety concerns of a floating cover…I understand… then consider a liquid solar blanket. 

In a few short weeks my guess is that we will all be wishing for some cool air, but in the mean time if you want to swim now and the cool water is keeping you out of the pool it may be time to add heat.  

Did you know the top of the line Heat Pumps reverse cycle and cool your pool in the summer, for those of you who don’t like the bathwater affect this is a great feature.   

If we can answer any questions you have or help you pick the right system for your pool or spa, please give us a call.
