Designed for the home owners that want to reduce their running costs and also keep their carbon footprint to a minimum, the Rinnai Hotflo Hot Water Heater Pump is the green solution to water heating.

The Hotflo’s key benefits include it’s ability to be retrofitted to virtually any brand of electric hot water cylinder. It is also a very simple installation which usually takes less than a day to complete. It also offered a significantly reduced carbon footprint alongside reduced energy consumption, making it a win all round. You can save up to 60% on your energy with the Hotflo.

The Hotflo Heat Pump is suitable for external installation on domestic applications that connects to mains pressure hot water cylinders.

A couple of things to keep in mind with the Hotflo
While it will operate at temperatures ranging between -7 °C to 45 °C, it’s output and efficiency will reduce as temperatures lower. For example, with an outside temperature of 20 °C, the Hotflo Heat Pump will deliver 3kW of heat output for every 1kW used. However, with an outside temperature of 10 °C, it will deliver 2.6kW per every 1kW used. It is also not suitable as a spa of swimming pool heater.

Certain water qualities are also not suitable for the Hotflo so it is important to check before getting one installed. The following are examples of water that would need to be treated before being used through the Hotflo:

• Hard water areas such as Wanganui.
• Aggressive water areas such as Christchurch
• Bore water areas where aggressive or hard water is found.

It is also not warrantied against corrosion in geothermal areas such as Rotorua where sulfur is present in high levels in the atmosphere.
