People need to heat their pools for different reasons. The heating is often achieved using a pool heater in most cases. Pool heaters are used to prolong the lifespan of the pool or to make it ready for instant use. When in need of a pool heater Key West FL offers the best place to visit. This article is a buying guide that one can use to make the right choice of a pool heater.
To begin with, these devices are designed to use different kinds of energy source depending on the model. Gas heaters are made to use either propane gas or natural gas. In most homes, people cook and heat homes using natural gas that is delivered through pipe infrastructure. If one has the piping for natural gas already done, it is advisable to buy a device that uses natural gas. However, there are also electric heaters that present a cheaper option.
Heaters are designed to operate at varying altitudes from the ground. Most typical ones operate at altitudes ranging from 0 to 2000 inches. Other designs are able to operate at heights of more than 9000 inches. When choosing, one should consider the design of their spa or pool to ensure that the device can operate optimally. It is best to take measurements before making the purchase.
These devices have different levels of Nox emission. In the United States, various jurisdictions enforce limits on the level of emission that heaters are allowed to operate within. The emission standards may be for commercial or residential heaters. Either way, it is important to choose a device whose Nox emission level lies within the set limits. It is often a criminal offense to surpass the set limit.
The durability of devices varies greatly. For durability, one should select a device that has cupro nickel tubing and exchanger as contrasted from copper devices. The choice of cupro nickel devices is because they are better for varying pH levels and salt systems. The shift to use resin/polymer headers among manufacturers is because these headers provide superior resistance to erosion and have better flow performance. The headers should be made of cast iron if the device is to be used for commercial purposes. This is mandatory in some jurisdictions.
The size of the pool is usually depended upon when making a choice of the size of the heater. Climate may also play a major role in the choice. The range of 55-130K BTU is usually recommended for polls that are located above the ground. On the other hand, the range for ground-located pools should be 100K and 400K BTU. In general, low temperatures in cold areas require more powerful heaters.
Modern heaters are usually lit through one of the two methods, that is, electronic or millivolt ignition. In millivolt ignition, there is a standing pilot light that stays lit always. On the other hand, in electronic ignition, the burners are lit with an intermittent spark similar to what happens in modern gas grills.
The regulation of gas usage is more efficient in electronic ignition. This ignition method also prevents leakage of gas. Gas leakage often occurs in millivolt ignition systems when the pilot goes off.
