- Pool Electro Heater
The Pool Electro Heater (electric resistance heater) provides simple, compact heating for swimming pools using electrical resistance elements to generate heat directly in the water flow. These heaters are typically smaller, more affordable initially, and easier to install than other heating options, making them suitable for smaller pools, spas, and situations where gas connections are not available or practical. They convert electrical energy directly to heat with near 100% efficiency at the point of use.
Our electric pool heaters feature durable heating elements, flow switches for safety, thermal protection devices, and simple controls for temperature adjustment. They are available in various sizes to match different pool volumes and desired heating rates. While they have higher operating costs per unit of heat compared to heat pumps or gas heaters, their simplicity, compact size, and ease of installation make them attractive for specific applications.
Electric resistance heaters are particularly suitable for indoor pools where heat loss is minimized, smaller pools or spas, temporary heating needs, or locations where gas is unavailable. They provide precise temperature control and can be integrated with time clocks or automation systems for scheduled operation. Proper electrical service capacity is essential, as these heaters typically require substantial electrical current at higher power ratings.
A typical 11kW heater draws about 48 amps at 230V. Operating costs are higher than other options - for a 20,000 gallon pool, expect $300-$500/month during heating season, depending on climate and usage.
Most require dedicated 240V circuit with appropriate amperage (typically 40-60 amps). Larger units may require 3-phase power. Always consult with a qualified electrician for proper installation.
Excellent for indoor pools! Since there's no combustion, no venting is needed. Their 100% efficiency at point of use and precise temperature control make them ideal for indoor applications.
Slower than gas heaters but faster than heat pumps. Expect temperature rise of 1-2°F per hour for average-sized pools. They're better for maintaining temperature than rapid heating.
Annual inspection of heating elements and electrical connections, regular cleaning of internal components, flow switch testing, and ensuring proper water chemistry to prevent scale on elements.
