Hotel Saves US $10k Annually With Rinnai Water Heater

After installing a Rinnai centralized gas water heating system, Harmony Phnom Penh Hotel has saved up to US$10,000 annually on electricity comparing to its previous electricity-based system.

Harmony Phnom Penh hotel was officially opened in August 2014 in Khan Daun Penh in Phnom Penh. Its 68 exquisitely furnished rooms, plus a wide range of services and amenities such as on-site fitness center, a roof-top swimming pool and jacuzzi, and a premium restaurant all require a hot water supply.

Mr. Ker Thai, the owner of Harmony Phnom Penh Hotel also owns the Ohana Hotel which opened in 2007. After experiencing high electricity costs due to a centralized electrical water heating system at the Ohana Hotel, which also required him to install a large backup generator as electricity supply was not stable at that time, he has noticed a huge saving after installing the Rinnai centralized gas water heating system at his Harmony Phnom Penh Hotel.

After installing the gas-based system at the hotel, he realized that it can save him up to US$10,000 annually on his electricity bill which is 50% cheaper compared with the energy costs of the previous electrical water heating system.

Despite the extra initial cost installation for the Rinnai gas system technology, property owners will start realizing the saving benefits in the long run after just three years of operation, according to a cost calculation by MEET-BIS Cambodia clean tech expert.

“I understand that it costs more at the beginning, but after 3 years, I can make profit as the product lifespan will last up to 10 years,” Mr. Ker said.

Many people have been afraid of the dangers of using an LPG gas-based system, but after visiting some 4 and 5 star hotels in neighboring countries where gas water heating systems are regularly installed coupled with the consultation with local, experienced people, Mr. Ker gained full confidence in adding the Rinnai gas water heating system to his commercial properties.

“I have no hesitation in installing a Rinnai centralized gas water heating system, because the products are designed and made in Australia with an HD water heater manufactured in Japan and backed by Rinnai’s global commitment to quality and safety,” said Mr. Ker Thai, asserting that, “What is important is that I believe in Camcona Trading Cambodia because it has imported and distributed high quality products and also has more experience in the construction sector.”

Besides the financial saving, the hotel is also reporting a reduction in greenhouse gas emissions of up to 73 ton CO2eq per year, which is a good result for saving the environment and promoting the business as a green hotel.

“Environmental safety and having a green hotel are my goals. We are doing business to make profit, but we have never forgotten to protect the environment,” he said, adding that. “I will remove all energy inefficient equipment from my previous hotel and replace it with energy efficient equipment in the coming year.”

The Rinnai gas water heating system was introduced to Cambodian market in 2013 by Camcona Trading Cambodia. Since then, more and more projects, especially hotels, have started installing this energy efficient water heating system to replace their electricity-based system.

The main benefits of a Rinnai centralized gas water heating system are; over 50% cost saving by replacing electrical heating to gas heating; lightweight and space saving; fast and continuous hot water supply (26L/min per burner); flexibility for future expansion; and low maintenance needs.
