Should you oversize your pool heater?
A pool heater can be undersized: if it cannot replace the heat lost through evaporative cooling, the pool's temperature will fall below the ideal. However, there is no such thing as oversizing a pool heater. The larger the heater's output, the faster it heats the water in the pool, and it will not begin short-cycling.

Sizing Considerations
- Keep in mind a few things when deciding on heater size: 1. The convenience factor.Natural gas is pumped in via a gas line for an endless supply, whereas propane needs to be housed in an oversized tank. Refilling this tank can be a logistical nightmare as it weighs hundreds of pounds when full. 1. How fast the water is heated. Do you want to be able to warm the pool in only a fe…
Other Considerations
- There are some additional variables you should account for as well. 1. The type of gas you’re using.Both natural gas and propane will do the job but from a cost perspective, natural gas is the less expensive of the two and in some areas can be up to 80% cheaper. However, propane is energy rich, so you’ll use less of it to produce the same amount of heat when compared to natur…
Size Really Does Matter
- Contrary to what women say, size really does matter – at least, as far as swimming pool heaters go. Correct pool heater sizing can be slightly tricky, but it mainly comes down to this: large heaters will heat quickly, whereas smaller heaters take more time to distribute heat throughout the pool. The choice is yours.
