Heat pump: How to save energy with my hot tub and swimspa ?

One of the biggest concerns when buying a hot tub is how much the hot tub / swimspa will cost and how it will impact my home's energy bill. There are several elements that we can configure when buying a hot tub , such as insulation ( Ecospa or Nordic Insulation system), the cover (included in all our Spas as standard), the consumption of the pumps (the more pumps, the more electricity consumption) and, of course, the consumption of the hot tub / swimspa heating system. This last point is what we are going to study in this article; we will assess how a heat pump can affect your energy consumption and how we can take advantage of this new technology in hot tubs .

I want a heat pump for my hot tub or swimspa !

Installing a heat pump in your hot tub / swimspa can provide several benefits including:

• Constant Temperature: A heat pump can maintain the water temperature of your hot tub / swimspa constantly, allowing you to enjoy your hot tub / swimspa at any time, without worrying about changes in air temperature.
• Energy Savings: Compared to other hot tub / swimspa heating systems, heat pumps are very energy efficient, which can help reduce your energy bill in the long run.
• Convenience: A heat pump can heat your hot tub / swimspa water quickly, meaning you won't have to wait long to enjoy your hot tub / swimspa .
• Durability: Heat pumps are designed to last for many years and are able to withstand a wide range of weather conditions.
• Low maintenance: In general, heat pumps require little maintenance, meaning you can enjoy your hot tub / swimspa without having to worry about its operation.

In short, installing a heat pump in your hot tub / swimspa can provide a more comfortable, efficient and economical experience.

When will I save by installing a heat pump in my hot tub / swimspa ?

The amount of energy savings that can be achieved by using a heat pump compared to a 3kW electric heater to heat the water in a hot tub / swimspa will depend on a number of factors such as the efficiency of the pump, the ambient temperature and the frequency of use of the hot tub / swimspa . However, in general, it is estimated that a pump can save between 50% and 70% of energy compared to a 3kW electric heater. This is because a pump uses the energy from the outside air to heat the water in the hot tub / swimspa , whereas an electric heater directly converts the electrical energy into heat. It is important to note that the initial investment in installing a heat pump may be higher than that of an electric heater, but in the long term, the savings in energy costs can offset this difference in cost . In addition, a pump may have a longer lifespan and require less maintenance than an electric heater, which can provide additional savings in the long term. To calculate the savings in euros that can be obtained by using a pump compared to an electric resistance to heat the water of a hot tub / swimspa , several factors must be considered, such as the cost of electrical energy, the efficiency of the pump, the ambient temperature and the frequency of use of the hot tub / swimspa . Below is a general formula that can be used to calculate the savings in euros: Savings in euros = (Energy consumed by the electric resistance - Energy consumed by the heat pump) x Price of electrical energy

So how can I save by installing a heat pump in my hot tub / swimspa ?

The secret of heat pumps is the COP (Coefficient of Performance), which is defined as the ratio between the amount of heat that the heat pump is able to supply and the amount of energy that is required to supply that heat. The heat pump that our Aquavia Spas / Swimspas incorporate has a COP of: This means that, for example, at a room temperature of 10ºC, for every 1.1kW consumed, the heat pump delivers between 4.45 and 4.83 kW, while with an electric heater, we will always be consuming and delivering 3 kW. This factor reduces the heating time of the hot tub / swimspa water and, consequently, the energy cost to keep the water at 36.5ºC, which is the temperature that we as a manufacturer recommend for a hydromassage bath.

What else should I know?

There are several factors you need to take into account:

• Our heat pump is fully integrated with the control panel , so you can control it comfortably from your hot tub / swimspa .
• The Aquavia hot tubs heat pump can heat or cool the water in your hot tub / swimspa .
• The maximum heat pump power is 5 kW.
• The average pump savings are 50 %-70% depending on the external conditions and the insulation of the hot tub / swimspa .
• Our hot tubs / swimspas with pump will always have an electrical resistance that will be activated in the event that temperatures are very low.
• If you want to install a pump in your existing hot tub / swimspa , contact your installer (it requires certain changes to the hydraulics as well as the electronic components.
• Heat pump maintenance is simple , but in general, it is recommended that the heat pump be inspected and maintained by a qualified technician at least once a year to ensure its safe and efficient operation.

Conclusions

Choosing the heat pump as an option for your new AquaviaSpa hot tub / swimspa is an ideal choice if you are looking for energy savings . It is an efficient system compared to traditional electric resistance that will allow you to save on hot tub / swimspa maintenance and, combined with the appropriate insulation options, you will save every day on your hot tub / swimspa .
