Hayward Gas Pool Heater Reviews

Hayward H400FDN Natural Gas Pool HeaterGas pool heaters remain the most well-known system for heat swimming pools. Now you can locate new gas-fired heater versions with substantially higher efficiencies than older versions. Depending on pool use
and your climate, they might not be the most energy-saving alternative in comparison to solar pool heaters and heat pump.

HOW THEY OPERATE

Gas pool heaters use propane or natural gas. As the pump circulates the water of the pool, the water
passes through a filter and then to the heater. The gas combusts in the combustion chamber, producing heat
that transports to the water that is returned to the pool of the heater.

They are most efficient when warming pools for brief intervals, and they are well suited for fast warming
pools. However, gas pool heaters may be an excellent option for pools which aren’t used on the regular basis.
Unlike solar pool heaters and heat pump, gas pool heaters can keep any temperature that is desired whatever
climate or the weather.

PICKING OUT A GAS POOL HEATER

You should take into account the following when picking out a gas swimming pool heater:

  • Size
  • Efficiency
  • Prices

SIZING A GAS POOL HEATER

You must have pool professional that is trained perform a correct sizing evaluation for your swimming pool
that is particular to discover pool heater size.

Many variables are involved by sizing a gas pool heater. Essentially, a heater is sized based on the
difference between the pool as well as the typical air temperatures as well as the surface area of the pool.
Other variables also alter the heating load for outside pools, including humidity levels, wind exposure, and
cool nighttime temperatures. So, pools found in regions with higher average wind speeds at lower humidity,
the pool surface, and cool nights will necessitate a bigger heater.

Gas pool heaters are rated by Btu (British thermal unit) end product. End products range from 75,000 Btu to
450,000 Btu.

There are a few bits of language you need to come to grips with before you can begin to comprehend pool
heaters. The first is BTU. This stands for British Thermal Unit and is, in straightfonNard terms, the quantity of
heat (energy) needed to lift the temperature of a single pound of water by one degree Fahrenheit. Straight
away you can see that in the event that you understand exactly how many pounds of water your pool carries
you can begin working out just how much heat is required to warm the water by a specific variety of degrees
F. Even though it’s not usually composed this manner it’s traditionally used as BTU per hour.

To compute an approximate heater size for an outside pool, follow these measures:

  1. Discover your desirable pool temperature.
  2. Discover the typical temperature for the coldest month of pool use.
  3. Subtract the typical temperature for the coldest month from the desired pool temperature. This may provide
    you with the temperature rise.
  4. Figure out the pool surface area in square feet.
  5. Make use of these formula to find out the Btu/hour output condition of the heater:
  6. Pool Place x Temperature Rise x 12

This formula relies on 1 to 1-1/4F temperature rise per hour and a 3-1/2 mile per hour average wind at the
pool surface. For a 1-1/2F rise multiply by 1.5. For a 2F rise multiply by 2.0.

The next period to comprehend is “efficacy”. It is a measure of how well energy (including natural gas or
propane with gas pool heaters) can be turned into heat in your pool water. In a perfect world all the gas would
be transformed into heat which will mean efficacy of 100%. Sadly, in the real world things aren’t quite so
great and most gas pool heaters have an efficiency between about 80% and top out around 95 percent.

DISCOVERING EFFICIENCY OF A GAS POOL HEATER

New pool heaters (gas swimming) have a normal evaluation they go through to discover their energy
efficiency predicated on their Btu (British thermal unit) output signal.

Heater efficiency is the proportion of useable output to energy input signal. As an example, an
80%-efficient heater uses $80 worth of useful heat for every $100 worth of fuel. So it squanders 20% of the
fuel.
