Rinnai’s Infinity A Series range of continuous flow hot water systems are suitable for all UK domestic and residential sites.

Rinnai’s Infinity A Series range includes ErP A-rated continuous flow gas-fired hot water heating units & systems designed for the UK domestic market. They offer high efficiencies and low running costs combined with on-demand, consistent water temperatures, seven days a week.   

The units are being specified and installed in a wide range of domestic properties from studios to high-end houses thanks to their ease of installation, energy and cost-saving benefits. Competitively priced, the units offer technological innovations at a similar cost to lower specification models.

Rinnai’s multipoint 17i water heater, for example, eliminates the problem of sudden changes in water temperature resulting in cold showers or scalding hot baths. If somebody is showering at 42°C and a tap is turned on elsewhere in the property, the temperature does not vary, and there is no chance of either user running out of hot water.

The Rinnai 17i interior model measures 675 x 370 x 139mm and weighs 18kg. The room-sealed unit has a temperature range of 35°C to 60°C with direct electronic ignition. Gas consumption ranges between 4.7kW-6.5kW for natural gas and 4.9kW-36.8kW for propane. Hot water delivery flow is an impressive 16 litre max flow.

Where an external installation is required, the Rinnai 17e external multipoint water heater offers greater flexibility at the design stage and is a viable solution where flue runs are problematic or internal space is not available. Capable of flow rates of up to 510 litres/min/hr at a 50°C rise, the 17e is suitable for multiple applications and can be specified for use with Natural Gas or propane. It also has full frost protection and is available with a range of ancillary items, including pipe cover box and security cage where necessary.

For smaller properties, the Infinity 11i interior unit weighs 2kg less at 16kg and consumes 6.10kW-21.60kW of natural gas and has an 11-litre maximum flow.
