WATER HEATING OPTIONS
Products That Are Taking The Chill Out Of Pool Water
Heat pumps are a popular choice for warming the waters of swimming pools in the UK, but there are a number of alternative products available which can also perform the task. The effectiveness varies with each solution, but whether it’s gas, electric or solar powered, the range of water heating options mean there’s something for all types of pools and budgets.

When it comes to the heating of water in swimming pools in the UK, there really is a wide choice of options available to suit an equally varied number of pool types and environments.
Whilst environmental systems and heat pumps provide some of the latest sophisticated technologies to meet the needs of many pool owners, boilers, electric options and solar power all play their part in the heating mix, and in doing so, offer flexibility for the many pool environments that exist across the country.
So whether it’s for a large, frequently used swimming pool or for a garden splasher that’s used for only a short spell during the summer months, in this issue we take a closer look at some of the non heat pump options that are warming up the waters of pools up and down the UK.
EFFICIENT WATER HEATING FROM GOLDEN COAST
Get fast and effective pool heating with the Pahlén range of electric heaters from Golden Coast.
With a Thermoplastic body and Incoloy 825 heating elements, the Pahlén Spa Heater has capacities of 1.5-3kW, making it suitable for small pools, spas and hot tubs.
The range also includes Pahlén Compact and Thermoplastic Heaters, which can be fitted with Incoloy 825 elements, or titanium elements if there is a high risk of corrosion, e.g. with saltwater pools. Both heaters are equipped with an integral thermostat (0°C - 45°C), overheating cut out and flow switch for easy, safe operation.
Adam Clark, Sales Director at Golden Coast said: “Swedish manufacturer Pahlén offers reliable, electric heaters that are costeffective and high quality. Whether you’re heating an above or below-ground pool, there is something in the range for everyone.”
Also available are Pahlén swimming pool heat exchangers, which can be connected to sources such as boilers, heat pumps or solar panel systems. Cross flow operation enables high output and exceptional heat transfer.
The Pahlén Maxi-Flo is a tube heat exchanger that offers capacities of 40-117kW, and is suitable for installations that operate under high pressure. It is made of acid-proof stainless steel and can be easily installed using adjustable stainless steel attachments. For extra durability, the Hi-Temp spiral heat exchanger is made of thermoplastic with a high glass content and a coil of acid-proof stainless steel.
In addition Golden Coast provides Bowman heat exchangers, which are extremely efficient due to the large number of heat transfer tubes. Bowman heat exchangers for solar panels are designed to work with the lower temperature water of solar heating panels, while maximising the effectiveness of the pool’s solar connectors.

pre-set and controlled with the push of a button. A digital display indicates the water temperature, and five LED lights provides owners and users with a system status, letting them know if the heater needs service. The easy-to-view, rotating digital display places controls front and centre, no matter how the MasterTemp heater is positioned.
On the outside the unit’s tough, rustproof composite exterior handles the heat and weathers the elements. The product’s compact design and super-quiet operation won’t intrude on poolside leisure time either. Inside, the heavy-duty (HD) unit with cupronickel exchanger stands up to the harshest of applications, like low pH, high flow or heavy use.
All MasterTemp models offer 82% thermal efficiency – the highest in its class – making these heaters extremely economical to operate. If a pool heater is more than five years old, chances are a MasterTemp heater could quickly pay for itself in utility bill savings.
Completing the product’s eco-friendly credentials, the MasterTemp heater is certified for low NOx emissions and outperforms industry standards.
TLS HEAT EXCHANGERS INCLUDE ‘GREEN’ CREDENTIALS
With the emphasis on sustain ability these days, heat exchangers from Thermic Leisure Supplies (TLS) are manufactured from 95% recycled materials.
Plate heat exchangers consist of thin, corrugated plates packed inside a frame, with the product in alternate channels, and service fluid in between product channels. The compactly designed TLS plate heat exchangers range consists of a number of herringbone patterned, pressed heat transfer plates. These are assembled in an inverse formation to create two sets of parallel channels, one for each liquid. Since the herringbone patterns point in opposite directions, a large number of points of support are achieved, creating a lattice in each channel. This provides a high level of turbulence, which in turn leads to an elevated rate of heat transfer.
Benefits of the TLS heat exchanger include:
• Heat exchanger completely contained positioned to sense the incoming water within the insulation: minimised thermal temperature and controls the pool to losses and condensation, high degree of within 1°C safety and comfort for those who work • The safety thermostat senses the water around the heat exchanger . temperature leaving the heater. • Low installation costs • Thermalec ® Heaters can be used in • Quick and easy access to the heat conjunction with other heating systems to exchanger for inspection provide year round heating solutions for • V arying options of stainless steel, titanium your pool or spa. plates with various thicknesses down to 0.4 mm with patented glue free plug in The new control system features a 3 or 4 design of NBR and EPDM gaskets stage (depending on heater size) power• Moplen, threaded or flanged connections. up sequence using electronic time delay W ith stainless steel, frames avoid Each electronic time delay relay is variable, corrosion and long product life, with easier allowing the sequence of start-up to be varied maintenance operations makes these heat to the requirement of the installation. exchangers suitable for both chlorine and salt water swimming pools.
