At Rustic Tubs we aim to think differently. We believe we are the only company in the UK offering air source heating as an option on our hot tubs. They are a reasonably priced option and will pay for themselves within 2 years of hot tub use.
What are Air Source Heat Pumps? It is a unit very similar to a small air conditioning unit in reverse. Instead of cooling the air in a room, it takes the heat in the surrounding air and converts it to be able to heat the water in the hot tub.
So why would I choose one? The heater has an average efficiency of 4 times over a standard inline electric heater. In the winter the efficiency drops to maybe 2 or 3 times as efficient, and in the summer can be as much as 5 or 6 times more efficient than an inline heater. Meaning that for every 1kW of power in, it will give an average of 4kW heat output. Therefore using a lot less electricity to heat your tub.
