Heat Pump Hot Water Systems
Heat pumps work like an air conditioner except in the opposite direction. Drawing heat in from the surrounding air to heat the water.
Heat pump hot water systems run on electricity and are extremely energy efficient and with the Government rebates available are also cost effective.
They are an ideal replacement of old electric water heaters especially when gas is not viable.
The only down side is that heat pump hot water systems tend to be quite bulky and may not be suitable for smaller areas.
