Questions, answered

Do I need any plumbing or special wiring?+

No. Every model runs from a standard 13A household plug and is filled with a hose. No plumbing or electrician required.

How cold does it get and how quickly?+

Models with a chiller reach a true 3°C and hold it. From a typical garden-tap fill, the Floating Thermometer chills down within a few hours and then maintains temperature automatically.

How much does it cost to run?+

A chiller typically costs £15–30/month in electricity plus filters — far less than bagging ice. Use our running-cost calculator for your own usage and tariff.

How is it delivered?+

Free kerbside delivery across mainland UK, typically within 5–7 working days. White-glove placement is available at checkout.

What's the warranty and after-sales like?+

The Floating Thermometer comes with a 1 year warranty and a 30-day no-quibble return. If anything goes wrong we send an engineer or a swap unit — we don't make you fix it yourself.
