June 2018
It has been a few months of varying weather patterns which has kept the Thermo Tech team busier than expected of late. 

We have decided that we would like all our customers to understand us a little better, so have made the topic for the changing season about Air Conditioning in both Commercial and Residential environments and the benefits that Thermo Tech can offer.

If there is anything specific that you would like to know about any service we provide, and can see a benefit of sharing this knowledge with all our client, please feel free to drop us a line on 0800 177 777 or email
Wireless Weather Station & Rain Gauge
Bob will be in touch to discuss your question and it may even be added as an article in our next newsletter. If your suggestion is used in an upcoming edition, we will send you out a home wireless weather station as a thanks for your contribution.

Be safe in these upcoming winter months!

Total Home Comfort

We are bringing our commercial knowledge of efficient ducted systems into the home environment.

Thermo Tech have identified a need for a quality solution to total home comfort. Many of our clients are demanding systems that maintain a comfortable temperature in the living and sleeping areas of their home during summer and winter.

For these individuals it is no longer acceptable to miss out on much needed sleep because the bedroom is too hot in the summer. Similarly, cold rooms that cannot be used in the winter are an impediment to full home utilisation.

Thermo Tech have been designing, installing and maintaining multi room systems in the commercial environment for over 26 years. Consequently, a depth of knowledge and experience in the nuances of ducted systems such as air movement and zoning are familiar concepts.

With more uptake in total home comfort systems we have been disappointed by the lack of understanding from many of our competitors who operate solely in the domestic sector. There is a big difference between designing, selecting and installing a single Hi Wall heat pump and a system that will create a comfortable environment in the whole home no matter what the season.


With any installation of a whole home ducted heat pump system with over 10kW cooling capacity ordered in the month of June 2018, we will upgrade your control unit with to allow WI FI Control FREE.

Things are changing at Thermo Tech

We started our Kaizen journey in spring last year and what a shock that was. If you know a little about Kaizen you will know one significant focus is eliminating waste (MUDA) and as we found out, we have more than our fair share. The first team meeting comprised of listing the problems that were creating waste. We walked away from that meeting with 2 white boards full of problems. MUDA is the Japanese word for futility, uselessness, and wastefulness. There are 7 seven types of waste and from these wastes we found our list of problems. The 2 initial wastes that stood out from our first meeting were DEFECTS and WAITING. 

Defects can be anything from incorrect/faulty parts to incorrect communications/plans. Waiting is what it says. Waiting for parts/equipment, information. Fast forward a couple of months and we are seeing the fruits of our efforts already with team engagement, and accurate reporting to see the wastes and work to eliminate them. Because if you can’t see the Muda you can’t fix it. Not every idea or solution works and that is the journey. We still have a long way to go and we will always be improving and standardising our services thanks to Peet and the team at the 

Recent Commercial Installation

They say a picture speaks a thousand words. And if I wrote a thousand plus words you wouldn’t read it. So instead here are just a few words. And some pictures! 😊 

We recently under took a job for a long-time client on their commercial building. 

Previously temperature control in this large building was preformed by 14 Air Conditioning systems. Roof top package units and ducted split systems with a vintage of nearly 30 years. And a combined cooling capacity of around 275kW’s.  

The buildings tenants and therefore the buildings use, and requirements changed. Which was a perfect opportunity to upgrade the entire HVAC system. 

Now used as a gym the HVAC system needed to supply outside air ventilation and cooling for up to 300 hot body’s (Pun intended) 

First order of business: Demo and remove the old systems from the building.
Next: New walkways, access ladder, and unit platform. 
Then we had a MONSTER crane with a 60-meter boom visit us, to drop our two new roof top package units into position. X2 (NZ made) Temperzone OPA960. 96kW’s of cooling capacity each, with two digital variable speed compressors each, EC plug fans, and economizer set up for free cooling (100% outside air supply) on those cold days/nights. Along with a sophisticated control system to operate both units in unison and fully adjustable/programable PLC software that can be accessed and adjusted from anywhere via the internet. 

Now, to give you some scope. Your average home wall mounted heat pump for your living space would be about 5kW’s of capacity. These units together provide 192kW’s of heat exchange capacity for this building. 
We then finished off the job with some extravagant industrial style exposed duct work that even John McClane would be happy to spend his Christmas crawling around inside of (Die Hard Reference). This duct work is important to provide an even distribution of ventilated cool air to the entire internal space.
The end result is a happy customer and hundreds of cool gym body’s. 
Our team is poised and ready for the next project they can sink their teeth into!

Commercial Air Conditioning


Comfort and it's effect on productivity

That feeling of comfort in your office space is both personal and complicated. Two individuals can be working in close proximity and be feeling differing levels of comfort. Satisfaction with the commercial environment will range across individuals for many reasons.

For this reason, at Thermo Tech we believe that commercial air conditioning is a specialist area of the market. The basic principles of air conditioning a commercial space are different to domestic, industrial and process air conditioning.

Because commercial air conditioning is primarily designed for occupant comfort a correctly functioning system has a significant part to play in the health, wellbeing and productivity of people.

When choosing a system there are three basic functions to consider that impact on occupant comfort and wellbeing, these are heating, cooling and ventilation.

Effective heating and cooling is a function of the architecture of the space, the design of the HVAC equipment and its application within that space. Effective ventilation is a product of the function of the equipment its design, selection and application.

Effective ventilation provides outdoor air to the space. The main reason for ventilation is to provide Oxygen rich air and flush away the products of human respiration, mainly Carbon Dioxide and moisture. There are other significant benefits of effective ventilation such as the dilution of odours, flushing away of pollutants and other emissions present in the space. It is not common knowledge that most systems in small to medium sized spaces do not include ventilation.

Comfort control of air conditioning systems can be a difficult proposition. Because of the natural differences between people’s perception of comfort it is never possible to create an environment that satisfies everyone.  For example, at certain times in the season commercial air conditioning in Auckland can switch from heating mode in the morning to cooling in the afternoon. This is not always desirable and can be an inefficient use of energy.

Equipment installation and location needs to be carefully evaluated. Regarding the indoor equipment, consideration needs to be given to where in the space it will be most effective.  For example, if installed too high and outside of the occupied zone then more space is being conditioned than is necessary. This is an inefficient use of energy and can cause access problems when the equipment needs servicing. The outdoor equipment needs to be as close as possible to the indoor equipment in a well-ventilated area. Traditionally outdoor equipment has been located on the roof. More recently this option has proved problematic for access if no internal roof access is available. Safe ladder access to any roof has its challenges, it can only be carried out in appropriate weather conditions and generally requires more than one person. Consequently roof located outdoor HVAC equipment where there is no internal access will add to the cost of servicing and maintaining for the life of the systems.

Our design team spend more time and energy considering these variables than most. We will visit the proposed space on existing buildings and study the plans for proposed buildings to ensure the system applied fully meets the needs of the occupants.
