Gas Pool Heaters – A Great Way to Enjoy Swimming Year Round

Monday, February 28th, 2011

Swimming is something that most everyone considers a warm weather summer activity. But when the weather cools if you have the right gas pool heater you can enjoy your pool, swim spa or hot tub year round no matter where you live.

How Gas Pool Heaters Work

Pool heaters work by re-cycling water, so the water will not be hot to the touch when it comes through the pool jets or inlets. Heat is added gradually as the water is turned over in the pool. Heat pumps, used in conjunction with a “solar blanket”, open the door to swimming on a daily basis in 85 degree water. Like a gas heater, the heat pump has the same requirements to operate. The pump must be operating efficiently, the filter must be clean, and the thermostat must be high enough to activate the heater.

Your heat pump runs on electricity. It requires 50 to 60 amps to run properly. Although it is much more economical to operate a heat pump, it heats your pool much slower than a gas-fired heater. Heat pumps are usually rated anywhere from 90,000 to 150,000 BTU’s, whereas a gas heater is typically between 250,000 to 400,000 BTU’s.

Common Complaints!

The most common complaint we hear about heat pumps is “my heat pump is not working!” However, if the fan is turning and it is blowing out cool, de-humidified air – that it IS working and you just need to give it more time. Another concern we often hear about is leaking. However heat pumps, just like air conditioning units, create condensation when functioning properly. So it is normal to have water leaking from the outlet at the bottom of the heater.

Advice for getting the most of out your gas pool heater:

Your gas heater will only operate properly if the following factors exist:

* Your pump must be operating efficiently

* Your filter must be clean

* Your Electronic Controller (PDA) must have the temperature set high enough to activate the heater

Therefore, if your pump strainer basket is full of leaves, or if your filter is dirty, or if your pump is not primed, your heater will not work. If your controller has your pool set to come up to 85 degrees and your water is already 86 degrees, your heater will not work.

One problem that has become much more prevalent lately is insufficient gas supply to the heater. In order for a gas heater to work properly, a commercial gas meter will be required. In addition, a “dedicated” line of sufficient size is absolutely necessary for the heater to function.

How to Build Your Own Solar Water Heater From Scratch?

Monday, January 31st, 2011

Solar water heaters are a relatively cheap and environmentally friendly way to supply households with hot water. Although the initial cost of buying such a device may be a little more than buying a conventional furnace, the fuel they use – the sunshine – is free and widely available for almost anybody.

According to some calculations, a solar heating system can provide as much as 85% of domestic hot water energy in many climates. Solar water heater systems can be used for heating homes or offices, and it may be used even for industrial purposes. It is very good at heating swimming pools, or it can be used for under floor heating. There are models available with evacuated tubes which allow the heater to function under cloudy skies. This kind of solar water heater will give hot water even at temperatures well below freezing.

Buying a solar water heater is worth considering especially for those who already have a house or plan to build one in the future. The reason for this is the fact that you can’t install anywhere a solar water heater. To the efficient function of a solar water heater, some calculations are needed.

Some of the solar water heaters tend to be rather complex, and their price tends to be quite expensive, at around several thousand dollars, but with the raising energy prices their initial costs will be paid back in only a few years.

One can choose to ignore all the pumps, sensors and control switches of a commercially available heater, and build a much simpler device. There are a lot of DIY-designs freely available on the Internet, and with a little luck you can have your own for about $5. You will only need such common and widely available parts and materials as buckets, scissors, some wood, a pane of glass, the back of a small refrigerator and aluminum foil.

The essential parts of a solar water heater are: a glass-covered “hot box” that catches the sun’s heat, some copper pipes that circulate the water in this box, and a storage tank that has to be set above the heat collector. Because hot water tends to rise while cold water sinks, the water heated in the “hot box” will move up to the storage tank, while cold water will sink to the heat collector.

This type of device, however, may be used only for camping, or as a science experiment. If you are considering making a more reliable and effective solar water heater for your home, you will have to search for a more complex design.
