Instantaneous electric system
Get hot water when you need it. No tank, no running out of hot water. These systems are more efficient as well because energy isn’t wasted on keeping a tank of water at a constant temperature. Instantaneous systems heat water when you turn on the hot water tap, providing hot water exactly when you need it.
Heat pumps
Heat pumps offer a great alternative to solar water heaters. Unlike solar heaters, they run all day and night without the need for sunlight. They even provide comparable savings to that offered by solar heaters without being dependent on weather conditions.
