When temperatures drop and your pool water follows suit, you can extend your swimming season by opting for an electric heater. Spring or autumn, swim in a heated pool! In this Pool Planet article, our experts detail everything you need to know about electric heaters: advantages, use, installation, etc.
What is a pool heater?
An electric pool heater is essential equipment for gradually increasing the water temperature and extending the swimming season. This device consists of:
- A control box to set the desired temperature.
- Immersion heaters containing titanium resistors; water circulates through them, heats up on contact with the resistors, and is then sent back into the circuit to return to the pool.
Generally, a pool heater is a compact device, combining the control box and immersion heater into a single unit.
The power of a heater, measured in kilowatts (kW), determines its efficiency: the higher the power, the faster and more effectively it can heat, even for large pools. There are models suitable for all types of pools (above-ground, in-ground, wooden, etc.), thus offering a flexible heating solution tailored to your needs.
The advantages of a pool heater
The use of a pool heater offers numerous advantages. First, it ensures optimal comfort by maintaining your pool at the ideal temperature all year round, from early spring to autumn, or even winter. Furthermore, the heater is the fastest heating system for warming your pool water, guaranteeing immediate comfort.
Compared to a heat pump, the electric heater represents a much more economical initial investment, often 3 to 4 times cheaper, while offering excellent performance.
Finally, the pool heater is simple to install: it takes up little space in the technical room and attaches easily to your pool's pipes thanks to a standard connection.
The pool heater is installed directly on the piping circuit, generally between the filtration unit and the water treatment equipment. It is powered like a standard appliance with 230V AC (or 400V for three-phase models) and connects easily to standard pipe diameters (50 or 63 mm).
Once installed, simply set the desired temperature: the heater starts up to heat the water until it reaches the set point, then stops powering the resistors while remaining on standby. This feature ensures a stable water temperature and prevents any heat loss.
How does an electric heater work?
Pool heaters are equipped with titanium resistors, a corrosion-resistant material. These resistors heat up under the effect of electricity, gradually transferring heat to the water circulating in the pipes. In a few minutes, the water temperature increases, offering ideal comfort for swimming, even for the most sensitive to cold!
