I am not ready to close my pool

It is hard to believe that summer is over. Our children are back in school, Friday night high school football games and a little cooler weather. My pool is beautiful and the kids love it.
Do not close it yet. Add a Heater. This is an easy installation for any pool. The heater will need to be installed next to the filter. If your filter is outside, then you have no problem at all. If your equipment is inside a building and you are going to add a gas heater, you will need to vent the gas fumes outside the building by adding a vent hood assembly kit.
Some heaters require either natural gas or propane and some require only electricity. Some heaters will have a standing pilot light that has to be lit and others require the electrician properly wire it and you turn it on like the thermostat in your home with a gas source with no pilot light.
If you decide to install a gas heater, this type could be either a propane source or a natural gas source. If propane type, your local propane company will deliver a propane tank and make the gas connection. If you use a natural gas heater, you will need to get a plumber to make the gas connection to your home gas meter.
Go see your local swimming pool dealer and learn about the different type of pool heater options. Swim earlier each year and extend the season longer. Now that you have that investment in your pool, why close it early.
