Steam Boiler Recommendation

Unical AG S.p.A. was established in 1972 to design and produce civil and industrial heating units and now boasts one of the most extensive catalogues in the industry. Unical R & D has a team of over 30 employees who continuously work on projects such as co-generation, revolutionary condensing heat exchangers and highly compact and modular applications to maintain the highest quality standards.

Steam is a fundamental and process for many industrial sectors including pharmaceutical, food, chemical, paper and many more production facilities, as well as for sterilisation and large scale energy production. A steam boiler is a pressure vessel that converts water to hot steam through a combustion reaction between fuel and air, which ignites a flame into tubes submerged in water. The heat contained in the steam is used for whichever heating process is required.

Tubman Heating has a long and respected relationship with Unical and we have installed a number of their steam boilers in New Zealand, including a recent Unical Bahr 3000. Our steam boiler recommendations as shown in the video below can be found on our steam boiler page.

Steam Boiler Replacement Case Study

The customer’s brief required replacement of a 1974 Anderson Steam Boiler due to age, as the average life span of a steam boiler is 20 to 30 years, and to increase maximum capacity since installing additional steam operated equipment such as a pasteuriser and CIP (Clean in Place) system.  

Tubman Heating replaced the old boiler with a Unical Bahr 3000 fitted with a Prolec Control Panel, for unattended use. This steam boiler will provide a reliable supply of steam to the production facility. The Prolec control panel allows for customization and increased safety controls, to suit New Zealand requirements. The customer is sent a notification via text or email if there is a fault.

Unical Bahr 3000 steam boiler

The Unical Bahr 3000 steam boiler is connected to a new pasteuriser and existing waste water treatment station with a new 80 mm steam line that runs through the production area. This process was made complicated by the pipe running through the roof structure, but with scaffolding and strict health and safety measures our team completed the task and, in some areas, even on their hands and knees.

An economiser has been fitted to the boiler to capture waste heat from the flue gases to pre-heat the boiler feedwater. The boiler coupled with the economiser provides up to 95% efficiency compared to the previous boiler that operated at ~80% efficiency.

On 3 December 2021 the New Zealand Government moved the whole of NZ into the Protection Framework (traffic light system) as part of the next stage of the COVID-19 response. On 15 December the boundary around Auckland and Port Waikato will ease, with certain restrictions. We need to be prepared to do what we can to minimise the extent of the spread of COVID-19. This includes being fully vaccinated and following public health advice.


Tubman Heating Limited’s staff are 100% vaccinated, and as an essential support business our staff have and will continue to adhere to strict health protocols including the use of PPE and maintaining social distancing as much as possible.

While Auckland is in RED our offices are open, with RED protocols in place. Visitors will be met at the office front door entry only.

Sitting down with our CEO Mike Buckley

Michael Buckley joined Tubman Heating Limited in September 2021, in the first stage of Auckland’s longest lockdown. After 3 months of virtual meetings with his new team, customers and suppliers, Mike is now able to meet one on one with the virtual faces he has come to know. We chat to Mike about his work experience, lockdown’s and goals for THL.

Michael Buckley - CEO
1. Tell us a bit about yourself?

I live and work on the North Shore of Auckland with my wife and two primary school-aged children that keep both my wife and me on our toes. I grew up in Canterbury, so follow the Crusaders and All Blacks rugby teams, please don’t hold that against me! I moved away from Christchurch over 25 years ago but still call it home. I have a long history of employment with specialist trade companies, spending 20 years working both in New Zealand and overseas for a fire protection company. One of the things you learn when travelling is you need to be agile, and your management style needs to be flexible due to ethnic and cultural diversities within your workforce. For anyone who is looking to advance their careers; working and living overseas provides an opportunity to learn new and interesting ways of managing a workforce and helps to make you a well-rounded manager of people.

2. Why did you join THL?

Tubman Heating offered a great opportunity for me to take the next step in my career. Having total accountability for a business was both scary and exciting at the same time. I had previously worked alongside Tubman Heating while working at Ventia and the culture and the way the two directors, Chris and Jim, managed the business was a great fit for me. Also moving back into a specialist trade industry felt like the most logical thing to do.

3. What do you feel is THL’s biggest strength right now?

Tubman Heating has a depth of knowledge that is second to none in the boiler industry. This team really knows its stuff. We have good solid processes in place and have Telarc ISO9001 quality and 5 Star Prequal H&S certification as recognition of our success. We have many products that we source directly from internationally recognised manufacturers but also good local knowledge to ensure we comply with all New Zealand standards for installation, servicing and maintenance. One of the key advantages that I see from Tubman Heating is the commitment to our customers and the drive to move clients from a reactive maintenance mindset to a planned preventative mindset.

Another strength within Tubman Heating is the respect and inclusion of the staff that work for us by our managers and directors. The directors care for the Tubman Heating team and see them as an extension of their own family. It is refreshing to have directors who truly care for the well-being of all our staff.

4. What is your goal for THL?

One of the challenging aspects of taking over a successful business is, “where to from here?” The key to any successful business is having a plan and working closely with the directors on agreed goals and a shared vision for the business. Over the last three months, the directors and I have been working on a strategy for the future, including looking at new technology that will move our industry away from reliance on fossil fuels to replacement fuels including hydrogen, wood pellet, bio and electrical sources of energy. Tubman Heating as a responsible corporate citizen is looking at its carbon footprint and has started down the path of leasing hybrid and electric vehicles. We also recently replaced our Auckland LPG forklift with a new electric forklift. Our goal over the next 3 years is, where possible, to move our fleet to electric vehicles and our customers away from fossil fuels.

Health and Safety is always at the front of mind. We are continuously developing ways to make it easier for our teams in the field to log and report safety interactions. The boiler industry is surrounded by hazards including gas, pressurised vessels, electricity and heat. We always need to be vigilant and continually improve our health and safety culture so that everyone goes home safely.

Our growth over the last number of years has been significant and through both organic and acquisitions, we will look to continue this growth in the coming years.

5. How has the lockdown in Auckland and Waikato affected THL?

One of the most challenging aspects of taking over running Tubman Heating was that I started this role on the 1st of September, right in the middle of a lockdown. Key to running any business is understanding your staff and what motivates them. This was challenging from in front of a computer screen. Through regular catch-up conversations over MS Teams and phone calls, I now have a good understanding of the team and how they operate. During level 4 Auckland was very quiet and our revenue numbers were significantly lower than forecast, this was not unexpected. During level 3 in both Auckland and Waikato, we had customers requesting maintenance and project works which helped us through. One of the advantages of having multiple branch locations is that although our Auckland business was slower than normal our Wellington and Waikato businesses have continued to operate as normal reducing the impact of the lockdown to some extent.

It was wonderful to gain insight into what motivates our CEO and we look forward to working with Mike to develop Tubman Heating Limited throughout New Zealand.

Why is regular boiler maintenance important?

Instead of waiting until there is a problem with your boiler, servicing it every 3 months will reduce the chances of any serious and expensive breakdowns. Ongoing maintenance of essential heating equipment is integral to keeping certain organizations running efficiently. A boiler breakdown for industries such as hotels, hospital, food manufacturer and other steam applications, is going to have a huge and immediate impact on the business.

regular services

Tubman Heating Limited is available 24/7 all year round for emergency boiler and burner repairs, but preventative maintenance can reduce the risk of large scale breakdowns or limit the downtime caused by a breakdown. Quarterly services allow for checks on the boiler, burner and associated equipment for faults, damage, leaks and everyday wear. Cleaning the heating system is an important part of this process as rust and dirt can create extra stresses on the machinery, while allowing our technicians to properly assess all relevant components and their effectiveness. During a service, technicians can recommend upgrades, replacements and improvements to your heating system to ensure your heating system is running optimally.

importance of maintenance
THL service

Keeping your staff and customers safe is of the highest priority for all businesses in New Zealand. In order to do this, heating equipment should be maintained and inspected regularly to ensure it is operating optimally and safely. Incomplete combustion can be hazardous to the environment and damaging to the operation of the burner, therefore our technician will perform a combustion analysis and set the burner for optimal efficiency and safe operation during a service.

Steam boilers require an annual inspection by an authorised inspection agency to verify the ongoing safety of the boiler. Our technician will prepare the boiler for an internal review by the Inspector, followed by a steaming test to verify that the boiler is safe to operate.

To set up a regular maintenance schedule for your heating system, contact Tubman Heating Limited and speak with our Service Co-Ordinator Tracy on 09 444 5076.

Extending the life of a steam boiler by upgrading its controls

During the 3 monthly service at Apparel Masters in Hamilton, a professional laundry and commercial dry cleaner, our technician found that the burner was running inefficiently with the components worn due to age. The control panel parts were brittle and the cabling needed upgrading for both efficiency and safety. Our Senior Service Technician advised the customer to upgrade the burner and control panel to extend the longevity of the boiler.

A new control panel with all new components were installed with new cabling from the control panel to the boiler. The newly installed C.I.B Unigas fully modulating E205A natural gas burner is a reliable and economical burner that is widely used in New Zealand. The high-performance combustion head is designed to achieve maximum efficiency when working on natural gas.

The upgrade and annual survey were completed over a weekend to minimise operational disruption for the customer. Apparel Masters in Hamilton shut down on Friday afternoon and steam was provided by Monday morning.
