Enjoy More Efficient Heating

If you love using your hot tub through the colder months, heating costs may be on your mind.

An air source heat pump uses heat from the surrounding air to warm your hot tub water. With a suitable unit and installation, it can use less electricity for heating than a conventional electric heater.

The right choice depends on your hot tub, how often you use it and the conditions it needs to work in. For winter use, low-temperature performance matters—not every heat pump is designed for the same operating conditions.

Savings vary with the model, outdoor temperature, electricity tariff, insulation and how you use your hot tub. We’ll help you assess the options for your setup.

Taking a Break Until Spring?

If you’re taking a break from your hot tub, simply switching it off and draining the visible water may leave water trapped in internal pipework and components.

Our Spafix Hibernate service provides professional winterisation for tubs that will be out of use for an extended period, helping reduce the risk of damage from freezing residual water.

Winter Hot Tub Problems: What to Check and When to Call Us

Hot tub not heating, losing water or showing an error message? During colder weather, it’s worth investigating changes in performance promptly, particularly if heating or circulation has stopped.

Here are some common problems, straightforward checks and signs that you need professional help. Always follow your hot tub manufacturer’s instructions.

Why Is My Hot Tub Not Heating in Winter?

Start by checking the selected temperature and heating mode. Economy or sleep settings may limit when your hot tub heats. Check the water level and follow your manufacturer’s guidance for cleaning the filters, as restricted flow can affect heating.

If the water still won’t warm up, a heater, circulation, sensor or control-system fault could be responsible, even without an error code. Our engineers can investigate the cause and recommend the appropriate repair.

Colder weather increases heating demand, especially while the cover is open; however, a persistent temperature drop or failure to reach your usual setting deserves attention.

Check that the cover fits securely and look for damage or deterioration. Note whether the temperature falls only during use or also when the tub is covered. If heating performance has changed significantly, contact us to arrange a diagnosis.

Repeated electrical tripping can indicate a fault with the heater, pump, wiring or another component. It needs professional investigation. Stop using the hot tub and don’t repeatedly reset the breaker or attempt to bypass it. Keep away from electrical equipment if there is water nearby, and contact a qualified professional.

During freezing weather, tell us that the tub has lost power so we can advise on the next steps.

Weak jets or reduced water movement can be associated with low water levels, blocked filters or pump problems. Check the water level and consult your manual for the recommended filter-care procedure.

If a pump is humming without moving water, making an unusual noise or displaying a persistent flow warning, arrange an inspection. Loss of circulation needs prompt attention during freezing conditions.

If you’re topping up more frequently than usual, or noticing unexplained water around the base, your hot tub may have a leak.

Make a note of how quickly the level drops and where you can see water. Photos can help our team understand the problem. Avoid continuing to run the tub below its manufacturer’s minimum water level, and seek advice promptly if the leak is substantial.

Contact an engineer promptly if your hot tub loses heating, circulation or power during freezing conditions. Water remaining inside the system can be vulnerable to frost damage.

Keep the cover secured to help retain warmth while you seek advice. Don’t assume that draining the visible water will fully protect the pipework and components. If you suspect anything has frozen, don’t try to restart the equipment before getting professional guidance.
