Pool Heater & New Plaster: Risks & Curing Time

Using a pool heater on a newly plastered pool can have adverse effects if not done properly. Here are a few things to consider:

- Plaster Curing Time: Newly plastered pools need time to cure and harden properly. Plaster typically requires at least 28 days to cure before the pool can be filled with water and heated. Using a pool heater too soon can interrupt the curing process, leading to weak and brittle plaster.

- Temperature Control: Rapid heating of a newly plastered pool can cause thermal shock, leading to cracking or peeling of the plaster. It's important to gradually raise the pool's temperature over several days. Start by setting the heater to a low temperature and gradually increase it by a few degrees each day until you reach the desired temperature.

- Chemical Balance: Proper chemical balance is crucial for the longevity and durability of pool plaster. Using a pool heater without maintaining proper chemical levels can lead to damage to the plaster, such as etching or staining. Ensure that the pH, chlorine, and calcium hardness levels are within the recommended ranges.

- Pool Equipment: Make sure your pool heater is properly installed and maintained. Faulty or malfunctioning heaters can cause uneven heating and damage to the plaster. Regular inspection and servicing of your pool heater are recommended.

By following these guidelines and seeking advice from a professional pool service or plastering company, you can minimize the risks associated with using a pool heater on a newly plastered pool.
