Finding the right swimming pool heater can be tricky. There are so many options available on the market for you to choose from, but we will ease the process by giving you a few tips and tricks that you should know before searching for your perfect heater. -        Your heater size should depend on the time needed to heat your pool or spa to your desired temperature. If you wish for rapid heating and tend to heat your pool prior to each use, you should scope out larger heaters. -          A smaller unit would suit you if you prefer to gradually heat your pool to the perfect temperature and then maintain it as such.   You should gather some technical specifications about your pool or spa in order to find the right heater to fit your needs. Some of the things you should find out are: -         Indoor or outdoor pool? -          Powered by propane, natural gas, or electricity?  All have their pros and cons. -          If outdoor: the amount of sun exposure your pool receives, and average wind speeds -          Your ideal temperature maintained and temperature rise per hour -          The surface area of your pool -         How much volume can your pool contain? (Length x Width x Average Depth x 7.48) -         Use of solar blanket? -          Length of pool pump usage per day -         Where will you place your heater? Is your equipment pad large enough? This information will help you decide what size suits you best. Typically, anything under 500,000 BTU (British Thermal Units) is considered a residential heater.
Gas heaters are more suited for rapid heating in a short time span, but may be more costly to operate.
Electric heaters are less expensive, but require a longer time span to heat up.
Where you decide to place your heater will be critical, as you must ensure that it is not placed within 5 feet of the inner surface of your pool. Also, make sure to leave enough room for quick access for easy maintenance or servicing, and ensure proper ventilation. Carbon monoxide is produced, so take care to keep ventilation away from doors and windows if placed outdoors, and have a licensed installer check to ensure appropriate ventilation for indoor heaters. There are local codes that must be followed during installation. Check that you are acting in accordance with the codes in your area. If you are placing your heater indoors, you should (after checking with the code) install your heater elevated a few feet off the ground, as propane weighs more than air and will settle near the floor. Solar heating can also be very beneficial and save you money by working with your heater to warm your pool. With a solar heating system (ie: solar blankets or solar dome), you will be able to install a smaller heater as the solar power will easily warm your pool by natural means. As a pool or spa heater is an important and costly investment, it is recommended that you seek the advice of a licensed contractor who understands all these requirements, can give a professional opinion, and can ensure a job well done.
