Elemental spoke with Chris Goggin, the director of operations at Rinnai, about new heat pumps, DME, and the company's goals towards renewables.

This year, how has Installer SHOW been enjoyable for you?
As usual, the exhibition is fantastic; it is incredibly well-organized, with a diverse mix of home and business owners as well as a variety of speakers who will pique the attention of installers, manufacturers, and customers alike.

During the show, you must have spoken with a lot of individuals. What topic is everyone discussing?
There is undoubtedly a more commercial component to what people are talking about, especially when it comes to how we might circumvent the complexities of commercial structures in a way that is realistic, affordable, and technically possible. Many discussions have focused on heat pumps, heat pump hybrids, and even the possibility of using renewable gaseous fuels and renewable liquid gases gaseous fuels in the mix.

Do these discussions represent the broader changes occurring in the sector?
The industry is at a tipping point where people and businesses, especially end users, are starting to recognise that using a combination of solutions would be the best course of action. For obvious reasons, people are interested in our R290 commercial heat pump family; nevertheless, people are also interested in how we combine those hybrid systems.

A vast array of technology is available from Rinnai. Which technologies, either from your own portfolio or one that you believe will take centre stage in the upcoming months, excite you the most?

Since the mission of Rinnai is to promote healthier living, our electric, hybrid, and commercial heat pump products are technology neutral. We are working on our DME and renewable liquid fuel, which we are quite pleased about since it will be the next generation of off-grid fuels. That is a very fresh topic for the industry and for us to discuss, in addition to the current discussion regarding hydrogen.

There has been a lot of discussion about the difficulties of decarbonisation, as usual. What do you think are some of the major challenges facing this sector right now?

The intricacies of construction are the main challenges I see facing the sector. We find ourselves in a situation where the government has sparked a debate about technology vs technology, but the debate about is really on an energy level and how we provide clean energy to power the future. Can we generate low-carbon gases to support that and electrify the system sufficiently to meet the entire demand? Amidst all of that, there is a highly intricate architectural styles in the current building stock that needs practical solutions, therefore we need to produce workable, affordable, and technically sound solutions for the variety of buildings that are out there.

What does the upcoming year hold for Rinnai?

Our R290 commercial heat pump portfolio has just been released, and we are also devoting a lot more time on applied sales. A significantly larger selection of commercial heat pumps and hybrids, ranging in capacity from 200 to 600 kW, will be available soon.

We are really excited about this, we are also looking forward to the completion of our renewable liquid fuel water heaters for commercial applications, we have spearheaded the downstream side of RDME product development and we are keeping a close eye on how this develops in the future.
