Many people are choosing to empty their hot tubs or swim spas for the winter (we do offer a professional winterise service which includes the following: drain down spa, hoover out bottom and jets, clean filters, and all completed by trained & certified technicians.) in order to reduce their energy consumption, which of course is a valid option! But if you, like us here at Castle Hot Tubs love to relax in your tub on a cold winters night looking up at the stars, heat pumps could be the way!
We are excited to be able to offer a solution that could reduce your hot tub or swim spas energy running costs by up to 80% as well as heating it up far quicker. You may have heard of ground source heat pumps used as an efficient way to heat modern homes, well the device we are talking about here is called an air source heat pump, and it effectively works like an air conditioner in reverse. Where an air-conditioner provides cool air; a heat pump emits heat. But how does a heat pump actually work?
The use of a heat pump is therefore extremely environmentally friendly. You save a lot of energy because the COP value (Coefficient of Performance) equals 5 or even higher. This means that per 1 kW of electricity consumed, you regain at least 5 kW of heat. Because of the high return, it is an energy-efficient solution to enjoy a pleasant water temperature in your pool or spa all year round.
On average a hot tub requires 3kW per hour when heating, so if you have an air source heat pump installed you could be using 1kW from your electricity source and the heat pump will be outputting 5kW to your hot tub heater which not only makes it much cheaper to run over that hour, but also is pushing an additional 2kW which will mean your tub heats up significantly quicker all for the price of 1kW.
There are a number of variations when it comes to specifications of heat pumps (we stock brands including Zealux, DuraTech, Superior Wellness and Gecko) and we would recommend getting in touch with one of our friendly experts to discuss what would work best for your set up, either by popping in to one of our showrooms (Johnston Pembrokeshire, Swansea or Bridgend), phoning or messaging us here.
We are working on a video showing the real-world cost savings that one of these amazing heat pumps brings to the table by testing a hot tub running off of one compared to the tub without the heat pump – stay tuned for that soon!
