Heat Pumps FAQ (sizing, inverter, noise, placement)

Hot Tub Heat Pumps FAQ

Do heat pumps actually save money?

In many real-world setups, yes — especially for frequent use. Heat pumps move heat from the air into water rather than generating it directly, which can improve efficiency in suitable conditions.

What’s the difference between inverter and non-inverter?

Inverter models adjust output to demand, which usually means quieter running and better real-world efficiency for regular use.

How do I choose the right size?

It depends on water volume and usage. Undersizing leads to slow heat-up and poor winter performance. If you share your tub model or litres, we can advise the best size range.

Where should I place a heat pump?

Allow airflow clearance, avoid boxing it in, and position it where noise won’t affect seating areas or neighbours.
