The Government’s plan to increase heat pump installations is “doomed to failure” without a substantial increase in training for installers, according to consumer advice specialists at The Heating Hub 

Pete Mills, Commercial Technical Operations Manager at Bosch Commercial and Industrial, delves into what heating technology may look like in the future

With the upcoming changes to building regulations as part of the Future Homes Standard, there is no doubt that heat pumps are set to play a significant role in the journey towards decarbonising heat in our homes.

Due to environmental and political pressures, manufacturing and construction companies are starting to replace gas boilers with more efficient products that emit less Co2. The question has to be asked “Will the traditional concept of a white box typically supplied with a first fix rail be replaced by a more practical device to better suit tomorrow’s heating and hot water needs?”

New coatings on surfaces can make the healthcare environment a safer one, says David Simoes

Rinnai is offering free energy audits on all sites.  

In the world of commercial boilers, the traditional rules of engagement are well documented: Manufacture a highly efficient unit that meets the expectations of the market, remove the old product from the range and sing the virtues of the new model’s features. It has been a successful strategy for many years, with incremental improvements delivering major developments over a decade.

With 2018 temperatures dipping to a stark -15oC and peaking at 35.5oC, building owners need to ensure they have sophisticated measures in place to manage the comfort of their employees, especially as there is currently no upper temperature limit for workers.

In the building services world, use of offsite fabrication equipment and techniques is gaining traction as a means of achieving improved quality and on-site safety through greater efficiency.

The government is investing £320 million in district heat networks. For some, this may be a new technology so it can in many cases be misunderstood and this lack of understanding means that some potentially efficient systems are delivering under par performance figures.

For any installer in the heating and ventilation industries, keeping up with the latest trends can be the difference between the business being successful or not. Quite often, these trends are based upon legislative regulations or guidance from government or industry bodies – it might be amends to Part L of the Building Regulations, initiatives such as the Renewable Heat Incentive, or health and safety updates from OFTEC.

Whether it is a school, hotel, library, gym, small office or even a large domestic property, space is a valuable commodity. Commercial property owners cannot afford to lose the space a bulky heating system or plant room takes up in their building. Owners and operators of these building are looking to get the maximum from the space they have available.

As businesses and organisations look to improve their building’s energy performance and cut costs and emissions, heating is a frequent starting place for efficiency measures.

The UK’s total gas consumption has fallen by 20% since 2000. In some parts of the country, more than 50% of electricity supplies are now being generated by renewables; and last year saw the first day since the industrial revolution when none of our electricity came from coal.

Recycling our rubbish has become second nature in the UK. But we are missing an opportunity to recycle our heat.

Currently supplying about 11% of global space and water heating needs, most heat networks today are fuelled by either coal or natural gas, while the national renewable energy share can range from 1% in China to 42% in Denmark.

The heat network industry is beginning to make a much-needed cultural shift from keeping the heat on at any cost to one that focuses on increasing whole system reliability and efficiency. This is part of a more holistic approach to maintenance and operation. 

Communal heating systems and district heat networks are considered by the UK Government as one of the most cost-effective ways of reducing carbon emissions from heating, especially as their efficiency and carbon-saving potential increases as they grow and connect to each other. They also provide a unique opportunity to exploit larger-scale, and often lower-cost, renewable and recovered heat sources that otherwise cannot be used.

Over the course of two years, Danny Bulch, director at Cedar Green Projects, replaced the boilers, gas fired water heaters and calorifiers in the Welcombe hotel, spa and golf club with new equipment. The main challenges of the project were carrying out refurbishment during peak heat requirements in winter; overcoming access issues to the plant room; and accommodating different fuel options.

Renewable technologies are becoming more commonly applied in UK homes, with more householders installing solar panels than ever before. But when it comes to sources of heat, most houses are still fitted with ‘traditional’ boilers, and many homeowners are unaware of the alternatives available. However, 2018 looks to be a turning point, with heat pump applications increasing because of the benefits they offer.

The Victoria Hotel in Sidmouth, part of the Brend Hotel Group, promises its guests that: “From the moment you step through the original carriage portico, you will be surrounded by warmth and refinement.” Where the exquisite décor and four-star service provides the refinement, a new A-rated efficient boiler from Potterton Commercial is now providing the warmth.

While district heating systems may have had something of a chequered history in the UK, the last few years have seen a considerable resurgence in their popularity. This is in line with the move to central energy centres, which make it easier to deploy both traditional and low carbon heat sources together.

According to the Building Engineering Services Association (BESA), offsite construction currently accounts for at least 3% to 4% of the UK construction sector. However, the cost and time savings and quality control benefits associated with this method will no doubt see it grow exponentially in the next decade.

Most MBS readers will be familiar with the phenomenon of thermal stratification, a frequent occurrence in high-roofed buildings where the natural buoyancy of warm air results in its accumulation at high level. Heating this unoccupied area of the space is clearly inefficient, exacerbated by colder air at high level being pushed downwards into the occupied zone by the warm air, increasing the demand for heating.

For commercial buildings, such as offices, hotels and leisure centres, a consistent hot water supply is a business-critical service. If a system fails, it can quickly force a business to shut its doors until a solution is found. Even more critically, you only have to look at the recent spate of legionella outbreaks in hotels around the UK to see the devastating impact a failure in water maintenance can have on a business. However, despite this there are still a large number of business owners who do not have a programme in place that meets the demands of their site.

One of the key recommendations to come out of the Dame Judith Hackitt’s Independent Review of Building Regulations and Fire Safety was for a clearer, more transparent and more effective specification process to put an end to cost-cutting compromises.

In the last few years, the energy management landscape has changed considerably and will undoubtedly change again in the future.

September traditionally hails the start of heating season, where thermostats click in, BMS systems relay information and commercial boilers fire into action to warm occupants feeling the first chilly morning of the autumn.

The UK has so far been successful in achieving interim targets for carbon reduction. But now the low hanging fruit is scarce, it’s time to tackle the big challenge head on - decarbonising our heat. Karen Fletcher looks at the options and the hurdles ahead.
