Heating

Oyster provides a full range of swimming pool heating systems to ensure your pool remains inviting for sublime, chill-free enjoyment. We are happy to advise you on the best solution to meet your requirements and budget.

There are many ways to heat your pool and Oyster Pools covers them all! These encompass gas (natural or LPG), oil, electric or solar. These are purpose-designed heaters for chemically treated swimming pool water. Swimming pool water is unsuitable for a normal domestic boiler, as the internal heating elements would be corroded by the chemicals in the water, instead a separate external heat exchanger must be plumbed in.

The method of heating a swimming pool is dependant on how the customer intends to use the pool. Firstly, will the pool be used regularly i.e. 7 days a week or will you only use it during weekends or at prearranged times. This is important because certain types of heaters, such as heat pumps, cost considerably less to run constantly than gas or oil heaters. However, if the pool is only going to be used on weekends, you may well benefit from the flexibility afforded to you by an oil or gas heater.

The capability to activate your heating a day or so before you wish to swim, is one of the benefits of an oil, gas or electric heating system. They also allow you to extend the swimming season of an outdoor pool. Some customers have been known to open and heat their outdoor pool over Christmas... However, as you can imagine, that would be quite costly.

The table below is an example of a typical seasonÍs running costs using different methods of heating an outdoor pool.

1. The pool is open from May - September and heated to 27°C / 80°F.
2. The pool is not in a high water table area.
3. Average depth is 4'' - 6'' / 1.4m
4. The pool is covered 20 hours a day with a solar cover / heat retention blanket.
5. The unit cost of energy varies in different parts of the country. Please factor in your personal unit costs.

All these factors need to be taken into account when choosing the correct heating system for your swimming pool. The key thing to remember when selecting a heating system is the balance between your initial cost of buying the unit, versus your long term running costs.

General Rules of pool water heating.

• On indoor pools, pool water heating should run in conjunction with an environmental control system. Click HERE for more information.
• For above ground pools, an extra 25% should be added onto your Btu / kW requirement. This allows for the extra heat loss through the sides of the exposed pool walls.
• A good quality heat retention or solar cover is essential to retain heat in the pool when not in use. Outdoor pools gain an extra 12-15% of FREE heat from the sun each day. Click HERE for more information.

Gas Heaters

Oyster supplies the leading British built Certikin range of gas heaters for swimming pools and spas, renowned for their technical innovation and reliability. The range, with heating capacities to suit all pool sizes, incorporates both natural gas and propane fired gas heaters.

Certikin Standard Gas boilers.

These heaters have been available for the past 6 years. They operate at around 80% efficiency, and have conventional metal fluÍs. They are available in LPG or Natural Gas (please specify).

Unless there is a specific technical reason to use the Certikin Standard Gas Boiler, we strongly recommend you consider the NEW Certikin ïGenieÍ Gas condensing boiler (see below for details). ïGenieÍ boilers use the latest condensing technologies, making them super-efficient and significantly cheaper to run. The retail price is only slightly higher compared to the standard boilers, so they are great value for money.

Customers feedback

Our existing customers who required a new gas boiler have received the NEW Genie gas boiler extremely well. The difference in performance between the standard boiler and the new Genie boiler is considerable. Customers report that they have noticed a significant drop in their heating costs, and they find the boiler much simpler to use.

Heat Pumps

Outdoor Heat Pumps - Free Heat from the Air!

For outdoor pools, significant savings can be made over traditional electric heating with a heat pump. A heat pump uses the same technology as a domestic freezer, but in reverse. It captures and enhances latent temperature in the air. You only use electricity to drive the fan and compressor, so in effect, for every eight units of heat energy captured, you only paying for two.

What could be better than using the earthÍs natural heat to warm your pool? With our range of Calorex outdoor heat pumps from Certikin, this is possible. Manufactured to suit a wide range of applications, these units transfer and upgrade heat from the outside air to the pool water. Heat pump technology offers an efficient and economical method of pool water heating, which does not rely on the sunshine, just air!

Our range of heat pumps includes models, which operate at ambient temperatures as low as -15 degrees centigrade, thus offering year-round heating.

Calorex heat pumps will transfer approximately four units of energy to the pool, for each unit of energy consumed. Amazingly, the sun does not have to be out for the heat pump to work. All Calorex standard units will happily operate with the outside air temperature as low as 0°C.

Calorex heat pumps are manufactured to suit a large variety of pools. The '20' range will successfully heat the pool water through a typical summer season, operating efficiently at an outside air temperature at or above 7°C. (Heating Season; May to September).

Heat Exchangers

Frequently, the most economical option for in ground swimming pool heating, our heat exchangers link to the house boiler, supplying heat to the pool when not needed for the house. This ensures that you can maximise your heating resources to keep your pool at a comfortable temperature without the cost of a stand-alone heating system.

If your house boiler is within 20-30 ft of your pools plant room, then it is often possible to fit a heat exchanger onto your domestic boiler. This is dependant on the BTU output of your domestic boiler and, whether it has enough spare BTU's to heat the water capacity of your pool. If your domestic boiler is too small, then it may be more economical to upgrade it. A heat exchanger could then be fitted to the upgraded boiler, ruling out the need to buy a dedicated pool heater.

Your second option if you cannot upgrade, is to purchase a domestic combi-boiler, install it into your plant room and heat the pool through a heat exchanger this way.

 

As a general rule you should allow 10 BTU's per gallon of required heated pool water.

BTU	List Price
60,000	£313.73
100,000	£358.38
130,000	£388.93
170,000	£414.78
230,000	£484.10
460,000	£1,189.10

You will also require a 2 pole thermostat to control the flow of hot water to the Heat Exchanger, via the hot water system on the boiler. £155.00 Inc VAT.

Please contact us if you need more detailed information on your BTU requirements, as each domestic boiler / heat exchanger installation is specific to your pool and its equipment.

Electric

Ingound Pools.

Thermalec pool heaters are unique, as they will operate with high velocity water coming from the filter, without it directly striking the heating elements. Instead, the water is deflected by baffles and is forced around the curved base of the heater.

The patented spiral flow around the elements removes all the generated heat, minimising the risk of scale or sediment collecting inside the heater. Any air pumped from the pool is allowed to pass harmlessly around the sides of the baffles and across the top of the heater. The control thermostat is positioned away from the elements, in order to sense the incoming water temperature and control the poolÍs temperature within 1°C.

Unlike conventional electric pool heaters, the Thermalec is guaranteed to hold its thermal efficiency for life, without regular cleaning or de-scaling. This means your running cost will not increase over time, and maintenance costs are drastically reduced.
