About Rinnai

Since Rinnai’s establishment in 1920 as a manufacturer of gas and oil appliances, Rinnai Corporation has steadily expanded its business lines. Today, as the world’s largest gas appliance manufacturer, Rinnai is widely regarded as the industry leader. With its headquarters in Nagoya, Rinnai Japan’s domestic network comprises 20 branches, 78 sales office and 4 production facilities (plus 7 outside Japan). Rinnai maintains a broad international presence through 15 subsidiaries and affiliates across the world. Rinnai’s corporate endeavours are guided by two customer driven principles: a commitment to safety and the achievement of a comfortable lifestyle. Rinnai companies share core values and a common corporate philosophy.

The Rinnai INFINITY ® gas hot water range still leads the market today, with the highest star ratings in the non-condensing category. Providing a saving of up to 66% in water heating each month, this is one of our best creations yet.

We, and the manufacturer, recommend that Rinnai commercial water heaters are serviced annually. Gas appliances should be serviced regularly for reasons of efficiency, reliability and safety.

Gas Appliance Specialists (2005) Limited undertake regular maintenance, repairs and replacements of Rinnai commercial gas water heaters in many commercial buildings in Auckland.

The company was founded by Nick Ray in 2005 and Nick has been associated with the Rinnai brand since 2000 when he worked as the Technical Manager for Rinnai. It was there that Nick saw the opportunity to specialise in the product, giving the customer the best support in the market. We are the only company that specialise in Rinnai’s product, and all our vehicles carry a large range of genuine Rinnai spare parts. Plus, as an authorised Rinnai service centre we are manufacturer trained and supported, and can carry out all maintenance and warranty requirements.

We appreciate that building managers often have their preferences when dealing with tradespeople and we have no issue in working with these trades. We have built good relationships with most of the associated trades such as plumbers and pump companies.

We can offer a 24⁄7 emergency call out service, if required, and can tailor a maintenance program to suit each individual installation.
