Size

The heating power of the pool heater totally depends upon the size of the pool heater. So it is very important to know the accurate size of your pool heater so that you can choose the heater that is best for your swimming pool size. In order to measure the size, you have to calculate in BTU (British thermal unit). It is the amount of energy required for increasing 1 pound of water one degree. This chart will help to calculate the exact BTU of your pool heater.

Size of Heater                Gallons in Pool         Surface area in Sq feet
100-200                                10000-20000                      Up to 300 sq ft
200-300                               10000-20000                       Up to 500 sq ft
300-400                               20000-40000                       Up to 800 sq ft
400 and above                   40000-80000                       Up to 1200 sq ft

The exact math behind the calculation of BTU

First of all, you need to measure the size of your pool and then you need to find out the exact temperature you need while swimming after that you need to calculate the external climatic condition of that particular area than subtract the desired temperature from the desired temperature. It will provide the exact number of degree by which you need to increase the temperature of your pool.

Now you have the temperature and size of your pool and these two measurements will help you in finding BTU/hour of your pool.

The formula of calculation of BTU is Area of Pool x Temperature x 12. This calculation will provide an idea about the BTU required in your pool heater.

Heating Time of pool heater

Heating time is not considered by everyone but there are some who prioritize this factor. If you are a person of hurry and wants an immediate boost in the temperature of pool water then electric pool water must be the right choice for you. If heating speed doesn’t matter then you can go with a gas heater or solar pool heater. These pool heaters will also save the cost of electricity.

Cost of pool heater

There are different types of cost that you need to pay for a pool heater like initial cost, monthly cost and maintenance cost. If looking for a long term cost effective method then a solar pool heater will be the best option.

In order to understand clearly, we have provided a cost chart below

Solar Pool Heater                High                       Low                       Low

Electric Pool Pump              High                       Low                       High
Gas pool Heater                  Low                        Low                       High

Size and Shape of Pool

The shape and size of a pool will directly affect the cost of a pool heater because if the pool size is large then you need a pool heater with higher BTU on the other hand if pool size is smaller then you need a pool heater with low BTU and the price of a pool heater is justified on BTU. In other words, we can say that as per the area of your pool increases the cost of heating that pool also increases.

Pool Ground

You also need to consider the surface of a pool that your pool is In-Ground or above the ground because of the prioritize heater choice for on ground pool is different from in-ground pool.
