Thermalair Health Check – Tom gains some healthy results!

Tom Davis is a man on a mission. Having qualified recently with an NVQ in refrigeration and air conditioning, Tom has certainly proved his worth as a very important member of our team.

His recent excursion to a medical practice saw Tom’s slightly innovative methods, utilising a Stethoscope to find out how poorly the incumbent VRV system was. Slightly eccentric you might say, but we are very pleased for Tom, and his hard work and dedication has certainly paid off!

However, we do suspect the use of a Stethoscope wasn’t part of the NVQ course!

All of our engineers are qualified to NVQ standards and hold all relevant skills cards. They are also trained to install the most sophisticated air conditioning, heating and refrigeration systems, including Thermalair’s incumbent status as a Daikin D1 Partner & Installer.

Daikin D1 Partner & Installer – What does it mean to our customers?

To demonstrate how important this is, is to firstly talk about the company. Daikin was established in Japan in 1924 and has an annual turnover of over £3 billion worldwide. Its research and development budget exceeds £100 million per year, which makes Daikin one of the largest manufacturers of air conditioning and heat pump equipment in the world. The company is also a manufacture of refrigerants, thus making it the only corporation that manufacture both air conditioning equipment and refrigerants. This puts Daikin in a unique position to apply international directives and anticipate refrigerant market trends and variations.

Daikin are undoubtedly the industry leaders in air conditioning and refrigeration systems. D1 partners are carefully selected by Daikin in the UK for their very high standards of design and expertise in the installation of systems. The D1 status recognises the necessary skillsets required to install the most advanced systems available from Daikin.

D1 status is only given to a select few of the UK’s air conditioning and refrigeration companies, those who are able to design systems for large retail, industrial and commercial environments. With an active ongoing communication with Daikin, a D1 supplier can advise customers on the many advantages available with Daikin systems, which can often lead to long-term savings and benefits to the customer.

So why should you choose Thermalair as a Daikin D1 partner?…

  • We are of course a long established partner of Daikin
  • Full design capability and advanced knowledge around the Daikin systems
  • Succinct and easy to understand proposals and quotations
  • Continuous training programmes with Daikin and their technology
  • We install, service and maintain systems, so provide a one stop shop for all your air-conditioning and refrigeration needs
  • Experience in the largest of retail, industrial and commercial environments, installing highly sophisticated systems, where business continuity is of the utmost importance
  • Recognised member of industry bodies and trade associations
  • Our engineers are fully DBS checked for works in more sensitive areas – Schools, Colleges, Nurseries and Care Facilities
  • D1 status means our customers get a 7-year warrantee as opposed to the standard five-year term with a non-D1 partner.

Very often a high level tiered partner status can be seen as relatively insignificant, but in the case of a Daikin D1 supplier, this has many benefits to the customer, providing absolute assurance that all of our projects will be completed to a 1st class professional standard. Not forgetting the extended guarantee period of seven years.

“We have had our installation completed yesterday and I just wanted to drop you a quick email to express how pleased I am with everything that Karl and his team did.

It has been a pleasure to deal with them, from the very first time that Karl came out and explained all my options to dealing with Jack this morning.

I would also like to say how lovely it has been to deal with Sara in your office who has always been really helpful.”  Kate Lanceman, Jodal Ltd

Should you consider air conditioning for the health and welfare of employees?

An increasing number of business owners are coming to the conclusion that air conditioning is not just about making their employees and customers feel more comfortable, but that this type of system does in fact comes with multiple, tangible benefits for the bottom line.

Here are just some of the key benefits of using air conditioning in the work place: 

  • Productivity in employees that feel hot or sweaty can be dramatically reduced. Air conditioning can increase productivity by always keeping a constant temperature and reducing humidity.
  • Properly serviced and maintained air conditioning systems may reduce employee days lost due to sickness because the installation can have filters which will reduce fungi and allergy-producing mites in the air.
  • Too much heat can make people feel stressed, which could in turn have a negative impact on the health of your whole team. Installing an efficient and well maintained system will mean that they feel more comfortable at work and benefit them mentally as well as physically.
  • If the workplace becomes too hot during the summer months, windows will need to be opened which could be a security risk for your company should they be left open or ajar after office hours.
  • If the servers or computers in your office overheat, it could cause huge problems for your business with potential loss of business revenue or opportunities if your network is down for any length of time. Air conditioning systems, specifically built to cope with keeping your equipment at safe temperatures will reduce your risk of lost business.
  • Current air conditioning systems can bring the temperature down to a desirable level in a room within minutes.  This can be very useful at the start of a workday when it is hot outside by providing some cooling relief to your employees or your customers who could be more receptive to hearing about your products and services if they’re not trying to fan themselves with your brochure!

Air conditioning systems are traditionally associated with cooling the air down, but there is also systems that incorporate heating mechanisms to increase the temperature should it fall below desirable levels.

Installing air conditioning in the workplace can be a great decision. If this is something that you would like for your business, or you want to find out more information, please call 01787 888659 or email:



Report highlights ventilation compliance ‘failure’ 

The Building Services Research & Information Association (BSRIA) has expressed its disappointment at the findings of a report that highlights the failure of ventilation systems to comply with Building Regulations.

The recently published Zero Carbon Hub report ‘Ventilation in New Homes’ describes a catastrophic failure of ventilation systems to comply with the requirements of Building Regulations Part F and negate the issues associated with poor ventilation, including indoor air quality, condensation and mould growth.

The report visited 33 dwellings across six construction sites during 2015, to see how effectively their mechanical ventilation systems were designed, installed, commissioned and handed over to occupants.

According to the report, the Zero Carbon Hub team found issues at many stages of the construction process at every site it visited, with significant underperformance of the systems as a result.

At five of the six sites, fans were operating at only half the required flow rates, with other common issues including flexible ducting being installed instead of rigid ducting, and long duct runs with multiple bends reducing performance.

Chris Knights, general manager of BSRIA Compliance, said: “Unfortunately, but not unsurprisingly, the report confirms that there is a widespread lack of understanding, at all levels, of the importance of correctly designed, specified, installed and commissioned ventilation systems.

“Moreover, the checking of final testing documents appears near non-existent. The report highlights the poor level of testing documentation available. A recent survey by BSRIA of calibration facilities also showed that less than 10% of the thousands of airflow measurements devices in use, by both electrical contractors and commissioning specialists, for ventilation system commissioning and testing, were UKAS calibrated in 2015 in line with the requirements of the Approved Document.”

BSRIA agrees with the report, based on its own experience at the commissioning/testing stage, and echoes that appropriate measures must be implemented, including whether voluntary certification schemes are strong enough to be part of the solution. The inspection and enforcement protocols for this ‘notifiable’ work must reviewed.


Thermalair undertake installations of heating and ventilation systems to large domestic and all commercial and residential development settings and in full compliance with current building regulations. Our team provide a full site survey and recommendations prior to undertaking the work.

De-stratification: Does it make sense? You bet it does!

Thermal stratification is a natural process that causes warm air generated in a building to rise to the ceiling or roof space depending on the building type with the displaced, cooler air being pushed down into the occupied area.

All buildings to some degree will experience thermal stratification, especially in high type buildings for example factories or warehouses.

This process will result in high temperature gradients and in turn high energy use for the bill payer.

In most working environments, employees need to kept warm up to a point of around 2m from floor level. This means in a 8 m tall building the bill payer is paying for 6 m to be heated when it isn’t needed!

What’s more, the temperature change between the working area and the top of the roof space could be as much as 5-6 degrees which is a massive waste of energy and money.

Destratification FanThere is a simple and relevant cheap process to solve the solution and this is by installing de-stratification fans at high level.

De-stratification fans working in conjunction with a heating system will allow the dispersion of the ‘wasted’ hot air at high level and push it down to the working area.

These fans work by a single phase power supply to each fan. The fans are fitted with a thermostat which can be set to the desired temperature (usually around 21 degrees centigrade).

As the temperature rises in the roof space and reaches the pre-set temperature, the de-stratification fans turn on and displace the warm air pushing it down towards the working area gradually to stop the feel of draughts, this makes a reduction in the roof space temperature and more even temperature distribution.

De-stratification  fans are able to reduce a buildings running costs and help maintain a required temperature in the working area, allowing for less heaters to be working. They are a great way of being energy efficient and cost effective.

R32: The Next Generation of Refrigerants

Focus on R32 – the next generation of refrigerants


There are a number of new options available for the new generation of refrigerants to meet future legislation and to cut Global Warmth Potential (GWP).

R32 is considered to be the best in the new generation of refrigerants available; this is due to its high energy efficiency and low GWP.

Reasons to change to R32


R32 has a GWP of 675 which is a third less than R410a (2088 GWP), which is the most common refrigerant in the air conditioning market.

Its energy efficiency results in a lower refrigerant charge allowing the manufacturer to manufacture smaller units for the global market.

R32 split systems are available in wall mounts, cassettes and these systems deliver:

  • Lower GWP
  • Higher efficiencies
  • Smaller refrigerant charge


With no extra cost on the equipment there is good reason to move with the times and install R32 when you come to install a new system or change old energy inefficient ones.

Ductwork & Air Quality Linked By Leading Association

ADCAS (the Association of Ductwork Control Contractors and Allied Services) is urging Facilities and Building Managers to focus on the cleanliness of their ductwork as central to the importance of indoor air quality (IAQ).

Ductwork in our buildings are a vital element of any building management system.

Poor IAQ has been linked to Sick Building Syndrome. This can reduce productivity in an office environment or impaired learning in schools.

Pollutant sources which cause low indoor air quality are from indoor and external factors.

Pollution emissions in an office environment can come from carpets, photocopiers and human traffic, these contaminants all impact the air quality, therefore the occupants of the building, ductwork and ventilation are so important for ensuring a good flow of fresh air into the building.

This requires the management/facilities company to make sure that all new and old ductwork is cleaned and in good working order.

Cleaning ductwork is something that needs to be regularly scheduled and carried out by professionals.

Ductwork is a technology that requires monitoring frequently to ensure a clean, pleasant and safe indoor environment. If left unserviced, not only does this cause air quality issues but also a fire safety issue to the building which could ultimately cost lives.

If you think your building has fallen behind in these standards, please contact us on 01787 888 659 and our experienced team will be more than willing to assist you.
