How do I know what size heater I need for my pool?
The pool’s surface area divided by three gives you the minimal BTU size recommended for that particular surface area. Continuing the example above with the 15 x 30 pool, after dividing by 3, you get 150. Therefore, the minimum size heater that is recommended for a 15 x 30 pool is 150,000 BTUs.
How many BTUs do I need for a 20000 gallon pool?
20,000 gallons x 8.3 lbs / gallon = 166,000 lbs of water that needs to be heated. Since it takes one Btu to heat one pound of water by a single degree, we now know that raising this entire 20,000-gallon pool by one degree will require 166,000 Btu of heat energy.
How do I calculate Btu for pool heater?
Multiply the surface area of the pool by the temperature rise. Multiply that result by 12 to arrive at the required Btu-per-hour output of the heater. This figure represents the heater output necessary to heat the pool to the desired temperature in 24 hours, based on an average wind velocity of 3.5 mph.
Can a pool heater be too big?
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.
What is the average life of a pool heater?
You can expect a gas or heat pump pool heater to last 8 to 11 years, with an average of 10 years. Regular usage and maintenance is key to a longer lifespan.
How many Btus does it take to heat a 40000 gallon pool?
For pools of up to 20,000 gallons, small heat pumps like the Hayward 95K BTU output are suitable. Pools up to 30,000 gallons should look at the AquaCal 120K BTU or higher, and 40,000 gallon inground pools should look at models like the Pentair 140K BTU.
How much does it cost to replace a pool heater?
On average, to install or replace a pool heater it’s going to cost you between $1,000 and $4,000. Installation alone can start at $500 and run up to $1,000. The average pool heater costs nearly $3,000 for the heater and installation.
Should I heat my pool?
Taking into consideration the need to conserve energy and to minimize fuel consumption, any unnecessary pool heating should be avoided. You are the best judge of the kind of use you want out of your pool. Use of your pool for recreation, exercise, therapy or just general enjoyment obviously will require heating it.
How long does it take to heat a pool 10 degrees?
To heat, an average pool (10-12K Gallon) with no solar cover typically takes 8-14 hours. By adding a solar blanket to your pool during heating you will greatly increase the efficiency of the heating process and keep evaporative heat loss to a minimum.
How do I choose a pool heater?
Choosing the perfect pool heater will depend on where you live and what type of heat source is available to your home.
- If you live in the north with access to natural gas, choose a gas heater.
- If you live in the north with no natural gas, invest in a heat pump.
What is a good pool size?
For a family of 8 people, a pool size of 18 by 36 feet is adequate. Even if you all decide to swim at the same time, there will be enough space for everyone. A rectangular shape is the best choice for this size of the pool. If there are six or less in your family, a pool size of 16 by 32 feet will be sufficient.
