Swimming Pool Heating Pumps

Dear Mmarona

I have sent you a quote for retrofitting all nine geysers. I have allowed for a single solar collector panel for each of the seven 150 lt geysers and three collector panels for each of the 450 lt geysers.  Each geyser is fitted with its own circulation pump and controller.

There are a couple of variables and a site visit will be required to confirm the viability of solar heating for each of the locations. 

I would also like to discuss the actual usage of hot water in a little more detail to ensure that we are looking at the correct options.  The solar option that I have quoted on is based on “normal” household consumption. Your consumption may be considerably different and there are other options available for higher demand usage e.g. heat-pumps which can deliver the same heat output as an electrical element at about 25% of the electrical consumption.

It would be helpful if you could give me some idea of average water consumption per person, such as how many people take showers at work, how many shower at each station and if they work shifts etc.  Perhaps we should schedule a discussion with someone who has these figures and other operational details at their fingertips.

Looking forward to your response.

Kind regards

If you are one of the many households that are looking to find a way to use more of the renewable natural energy sources, while at the same time cutting back on your dependence of the big energy companies, then a solar heat pump could be just the thing you are looking for. This is because a solar heat pump can be installed in your own home without too much of a bother and can cut back on the amount of traditional energy you have to use to heat or cool off your home. This can be a beneficial lift to your household budget, as well as the environment. We’ve all heard the talk about how now is the time to turn your house into a more energy efficient operation in order to help the environment, well, a solar heat pump can help you to achieve this.

The reason that the solar heat pump is so energy efficient is that it works to heat and cool your house naturally. In the summer months when there is a lot of heat, the solar heat pump pulls the heat out of a specific area in order to help it cool down. In the winter when the problem is that there is not enough heat in a specific area then the solar heat pump works in the reverse manner, making sure that the hotter atmosphere goes where it is needed to regulate a room’s temperature. This procedure may seem odd, but it works well and many people have started to turn to solar heat pumps as a way of getting away from traditional heating and cooling methods.

One of the main reasons that a solar heat pump is considered to be so much more energy efficient than traditional heating and cooling systems is that it relies on sunlight in order to work. This is a natural, renewable energy source. When you use a traditional form of electricity to power your heating and cooling system then dangerous CO2 emissions are being put into the atmosphere because of the use of oil and coal by the electric companies to provide you with that power. And, because the solar heat pump relies on the sunlight, there is hardly any operating costs at all that are associated with the system. Plus, they are easy to install and work on and this can mean lowered maintenance costs as well because so many times when your traditional air conditioner or heater breaks down you have to call in a specialized repair person in to look everything over. The costs involved with maintenance on an older heating and air conditioner system can be quite large and burdensome.

Something else that you should also know is that you do not have to worry about the solar heat pump not being able to work at night. The system is designed to store energy and can function even when the amount of solar radiation that it is receiving is low. Much like those solar powered outdoor lighting systems that store up the sunlight all day only to dispense it out to the lights at night, the solar heat pump can heat or cool your house down no matter the time of day or the weather conditions. However, people who live in areas where it is continuously cloudy or overcast should note that the system will not operate at its peak performance levels.

Even if you have a larger home you can easily use a solar heat pump to heat and cool your house. This system is designed to work both in small areas and in larger ones, so you do not have to be concerned that your larger home will not be adequately temperate. In fact, one of the reasons that the solar heat pump works so well is that it draws from a steady supply of renewable energy.

Tired of swimming in a cold pool? Is you spa not quite "hot’ enough? Thinking about investing in a new electric heat pump pool heater?
Here are some questions to ask when shopping for a new heat pump.
- How many BTUs will you need?
- Do you have the electric service required for a heat pump?
- Do you have the space to install a heat pump?
- What type of features do I need?
- Plastic or metal cabinet?
- Titanium heat exchanger?
- Digital controls or analog?
Let’s try to answer the questions above thus allowing for an educated purchase.
- How many BTUs will you need? - The size of your pool (amount of gallons and surface area square footage will dictate the BTUs required to heat the pool or spa in the most efficient manner. Also take into consideration the amount of strong wind which will effect your pool and whether or not you will be using a pool blanket to help hold the heat into the pool. Check the manufactures recommended sizing chart to help determine the correct size and model for your application.
- Do you have the electric service required for a heat pump? - Most heat pumps required 220Volts of electric and many require separate 50 to 60 amp breakers. Check with your local electrician to make sure you have sufficient electrical power to operate your new heat pump.
- Do you have the space to install a heat pump? - Most heat pumps will require a "footprint" area of about 40" x 40" and about 40" in height. Heat pumps need good air circulating space area around the units to allow for peak operation.
- What type of features do I need? Today’s heat pumps are manufactured with many different features, some are, Dual thermostats (great for a pool and spa combination), Scroll compressors, Extra quiet fan motors, Extended warranties, Built in water bypass valves, Ability to operate motorized valve actuators, Easy to see readouts with diagnostic trouble shooting messages, and many more. Check the manufactures literature to make sure you are choosing the heat pump with the features best suited for your application.

- Plastic or metal cabinet? Is you pool located in a location which would be better suited for a plastic cabinet?
- Titanium heat exchanger? The heat exchanger is the piece of equipment located inside the heater which the pool water flows through. Titanium is a much more forgiving material in that it allows for a greater tolerance of water chemistry problems. Other types of heat exchanger material is much more susceptible to problems with poor water chemistry. Please note: Proper water chemistry is a must when using any type of pool heater.
- Digital controls or analog? The controls on the heater can be digital electronic or analog. Once again it is best to consult the manufactures literature to gather which would be best for your application.
A swimming pool or spa heat pump is a large investment and should be researched carefully. Purchase the correct unit and you can expect many years of warm enjoyable water to swim and relax in.

If you are lucky enough to own your own swimming pool you will understand the importance of your pool heating system.

Without a swimming pool heater your pool can remain too cold to use for most of the year. The water is simply too cold for comfort and nobody will want to go for a dip. Warm that water a little and your swimming pool is immediately popular. But choosing an economical and effective swimming pool heater can be quite a headache.

In recent years many pool owners have moved away from traditional pool heaters that use gas, oil or electricity and they’ve started to use efficient, effective and environmentally friendly heat-pumps.

Heat pumps work by transferring heat energy from a source (usually the ground, the air or water) to the swimming pool water. They are remarkably energy efficient and environmentally friendly as they consume much less energy than they produce as heat. For example, a typical swimming pool heat pump system will consume around 1kW of electrical energy to produce 5kW of heat energy. This may seem like magic, but you should remember that the system is deriving much of its heat energy from the air or ground.

One of the most important results for many swimming pool owners is the reduced fuel costs. While the initial outlay for a heat-pump based pool heating system may be more than an equivalent traditional system that uses oil, gas or electricity the running costs will be far less. This means that the heat pump is likely to pay for itself very quickly. The other benefits of heat pump use are your swimming pool will be usable for more of the year and your carbon footprint will be significantly reduced.

When purchasing a heat pump based system there are lots of things to consider. For example, the material used to make the heater element can influence the price of these units enormously (titanium lasts longer but costs more). If you are interested in finding out more it is recommended that you speak to a reputable swimming pool supplier who has experience with a range of swimming pool heat pump systems.

Renewable Energy

Heat pumps offer the most energy efficient way to provide heating and cooling in many applications.  This is because they can use renewable heat sources in our surroundings, such as air and water.  Even when we think that it is cold, air and water contain heat that is being replenished by the sun.  By using a small amount of additional energy, a heat pump can capture the renewable energy and significantly increase the temperature to the required level.

Introduction

Almost every home has a refrigerator.  Many homes and vehicles have air conditioners.  Supermarkets, transport (ships, trucks, etc), factories and storage facilities use mechanical refrigeration technology.  These are just a small cross section of how mechanical refrigeration technology is used.

Heat pumps also utilise mechanical refrigeration technology.  It is believed that the first heat pump was manufactured in the 1930’s.  Through the use of advanced design techniques and specialised components, heat pumps can be very reliable and efficient heaters of air, water and other substances.

As a result of decades of ongoing development, mechanical refrigeration can be one of the most reliable technologies available in the world today.  However, the actual reliability is very dependent on the product design and the quality of the components used.

Uses For Heat Pump Water Heaters

Heat pump water heaters are used for many applications, including: hot water, pool and spa heating, space heating, heating for industrial processes.

How Heat Pump Water Heaters Work

In 1848, Dr John Gorrie wrote: "If air were highly compressed, it would heat up by the energy of compression.  If this compressed air were run through metal pipes cooled with water, and if this air cooled to the water temperature was expanded down to atmospheric pressure again, very low temperature could be obtained, even low enough to freeze water in pans in a refrigerator box".

In normal operating mode a heat pump uses the same process described in 1848, but in reverse.  As with most current mechanical refrigeration devices, air has been replaced by refrigerant to increase the amount of heat that can be absorbed and transferred.

Heat pumps can absorb heat from various sources - typically air, water or waste heat.  In this description we will focus on heat pumps which absorb heat from the air.  These are the most suitable and cost-effective units for South African conditions.
