decarbonisation – Building Specifier

EUROPEAN & GLOBAL MARKET FOR HEAT PUMPS LOOKS FOR WIDE EXPANSION

Chris Goggin looks at the expansion of the global heat pump market as they will play a pivotal part in UK, European and international decarbonisation plans. Rinnai observes the market conditions that will likely see heat pump technology become standard household appliances on an international scale.

Heat pumps will make a significant contribution towards global decarbonisation aims, of that there appears to be little doubt. The international heat pump market is projected to substantially expand as fossil fuels are phased out in favour of clean carbon neutral energies. Heat pumps are becoming seen internationally as trusted tools of decarbonisation with major economies across the globe adopting them as a preferred method of heating and hot water delivery to domestic and commercial sites.

Heat pumps will certainly be a major contributor towards the introduction of clean renewable energy across EU member states. The EU aims to increase the number of heat pumps installed in member countries with its REPowerEU plan. The plan covers diversifying energy supplies, producing clean energy and reducing overall energy consumption.

Current estimations on heat pumps that have been installed across Europe are around 20 million. 3 million of these heat pumps were purchased during 2022. European heat pump sales throughout 2022 resulted in a 39% increase, up 5% when compared to 2021.

France bought and installed more heat pumps than any other EU nation in 2022 when compared to 21 other European heat pump markets. 621,776 individual heat pump units were sold and installed in France throughout 2022. UK statistics show that the UK had sales of 55,168.

Scandinavian and Baltic EU states maintain the highest levels of domestic heat pump adoption – Norway has 60%, Sweden 43%, Finland 41%, and Estonia 34%. Norway has 1.4 million actively operational heat pumps that provide essential heat and hot water to domestic properties.

Heat pumps provide heating and hot water towards 16% of all domestic and commercial properties across Europe and there are further plans to install an added 60 million more by 2030. Heat pump technology is a certified method of clean energy dispersal and international market projections expect further expansions in size and scope. The current European heat pump market is healthy whilst the future heat pump market will continue to grow.

America is another area of importance regarding domestic and commercial property heat pump adoption. More heat pumps were sold and installed than gas furnaces during 2022. Heat pump sales amounted to 4.3 million whilst sales of gas fuelled heating and hot water systems were 3.9 million.

The residential heat pump market in the US was valued at $13 billion in 2020 and is expected to grow at a CAGR (Compound Annual Growth Rate) of 5% between 2021 – 2030.

American heat pump adoption has resulted in an 11% increase in sales of air sourced heat pumps during 2022. Heat pump sales throughout US territory have steadily increased for 20 years. In 2001, 1.44 million air source heat pumps were sold. In 2021, customers purchased 3.92 million air source heat pumps.

As in Europe, the American heat pump market performs strongly and is expected to grow over the coming years. In 2022 the US was the most dynamic heat pump market in the world – with a 15% increase in recorded sales.

Another significant player in the international heat pump market is China, which manufactures 40% of the world’s heat pumps. China is the globes largest producer of heat pumps with many of the finished units being exported to Europe.

Heat pumps are a recognised technology throughout all Chinese regions and play a key part in heating and hot water delivery as well as air conditioning. 58.4 million heat pumps have been installed in China as of 2020 – 33% of the world’s installed heat pumps. China is the biggest market for air source heat pumps with sales increasing by 7% in 2021 and 12.5 million units in operation.

In 2022 China recorded a 20% increase in air to water heat pumps compared to sales statistics in 2021. Over 1 million air source heat pumps were sold in China in 2022. China is currently the third most dynamic international heat pump market with a recorded annual 13% increase in national sales.

According to the website Global Heat Pump Statistics (April 2023) “Leading manufacturers are seeing promising signs that today’s momentum and policy support could put the industry on a trajectory that triples sales by 2030 – and they have accordingly announced plans to invest more than $4 billion in expanding heat pump production and related efforts, mostly in Europe.”

Heat pump sales increased by more than 11% globally in 2022. Widespread UK heat pump adoption is yet to be fully announced through sales and industry growth statistics. However, it can be observed that the heat pump industry and market is expanding exponentially, with the UK expected to also increase the size and levels of activity within the domestic heat pump market. Doing so will ensure achievable domestic and commercial property decarbonisation.

PRACTICAL, ECONOMIC AND TECHNICAL SOLUTIONS USING ALL ENERGY AND POWER OPTIONS WILL LEAD TO DECARBONISATION

Building News

Rinnai’s Chris Goggin reviews the Government’s ‘Powering Up Britain’ document & strategy which aims for NetZero by 2050.

“Powering Up Britain” is the Government’s own manifesto for a national strategy to achieve cheaper and more secure fuel supplies, decarbonisation and the goal of NetZero by 2050. ‘Powering Up Britain’ sets out the department’s approach to energy security and net zero and acts as an introduction to Powering Up Britain: Energy Security Plan &Powering Up Britain: Net Zero Growth Plan, both of which are complementary and should be read alongside each other. These documents were produced after High Court action by what can be neutrally described as the ‘Green lobby’ – a combination of interested climate groups. Mainstream media have taken their own views on this. For example the BBC reported this by saying, “The government was forced to release a new net zero strategy after the High Court ruled that the original plan did not contain enough detail, and breached the government’s legal obligations under the Climate Change Act.”

This latest government released document has attracted criticism from academics and environmentalists alike who stipulate this newly produced centralized literature amounts to a watering down of previous NetZero announcements and aims.

To maintain national fuel provision and decarbonise domestic energy supplies the UK government says it will shift away from fossil fuels and continue to construct renewable energy installations such as wind, wave and solar whilst increasing nuclear capacity.

Hydrogen production and distribution will also become increasingly more relevant as the government is keen on widespread CCUS (Carbon Capture Underground Storage used for blue hydrogen manufacturing) and green hydrogen development – both forms of hydrogen can be used for industrial and potentially property heat usage.

The new plan also sets out the following objectives:

insulating 300,000 of the UK’s worst insulated homes as part of a £1bn energy efficiency programme
aiming to remove between 20m and 30m tonnes of carbon from the atmosphere by 2030.
providing more than £350m for electric vehicle charging facilities
aiming to produce 25% of the UK’s electricity through nuclear power by 2050
speeding up the planning process for wind farms and solar energy sites

A main ambition of the “Powering Up Britain” strategy focuses on reducing electrical costs to be the lowest in Europe by 2035. UK energy strategists believe that clean and sustainable electrification is presently the safest way to ensure lower customer costs and carbon emissions.

We believe that manufacturers must adapt and offer the marketplace the variety and quality of products needed to achieve lower carbon through practical, technically and economically feasible pathways today.

Rinnai has adapted the range of low carbon commercial and domestic products to include technologies that support electrification. We now offer a range of products and systems powered by electric, natural gas, hydrogen-blends, BioLPG, rDME, Solar & Heat Pumps – all commercial heating & hot water systems.

For example, all Rinnai electric storage water heaters are designed with flexibility in mind. All units are fitted with between one and six titanium elements. The Kw rating within the Infinit-E range is scalable from 12kw to 72kw ensuring that our appliances are suitable for a wide variety of applications.

The overall Rinnai range is branded as H1, H2 & H3.

H1 – Hydrogen, BioLPG – water heaters & boilers.

H2 – Hybrid Systems – Heat Pumps and Solar Thermal.

H3– Heat Pumps – Low GWP.

Rinnai understands the green direction of current and future energy needs as well as the cost-of-living crises which has seen fuel costs rise to exorbitant levels. Not only has Rinnai adapted their current range to include hydrogen ready technology and products that accept renewable power such as solar and hybrid heat pumps.

Energy options will continue to expand across the UK and Rinnai will be constantly preparing products and technology that instantly provides the customer with reduced emissions and costs for their commercial or domestic property.

RINNAI CONTINUOUS FLOW HOT WATER REPLACES STORED SYSTEM AT HISTORIC ESSEX SCHOOL

General News

Holmwood House was opened in 1922 as a boy’s school by Mr and Mrs E F Duggan with the aim ‘to develop the individuality and abilities of each child, to make them self-reliant and adaptable’. The world has changed a great deal in the school’s first century, but it still upholds those underlying values.

Except for wartime evacuation, the school has remained on the same site, two miles from the centre of Colchester. In 1985 Holmwood House began accepting girls, and in 2006 the nursery was opened in Great Horkesley. The site needed to upgrade and update its hot water delivery system. The new hot water delivery system – comprising of 3 x Rinnai N Series 1600i units – was installed by SDF Mechanical.

Shaun Fuller, who started SDF in January 2018 has been working within the HVAC industry since he was 17 years old and has gained a wide range of experience over the last 13+ years. From working on domestic boilers within households to large industrial steam boilers in factories, he has a wide range of skills to meet all requirements throughout all sectors. Since starting the business Shaun has progressed SDF Mechanical Services into having a large customer base in all sectors in the industry and built close relationships with them. SDF Mechanical Services are Gas Safe and Oftec Registered and have a wide range of qualifications to be able to carry out various different types of work to the highest of standards.

For Rinnai Harry Barton commented,

“The diminutive size, lightweight nature (less than 30kg) and high performance of 960 litres per hour at a 50 degree rise ensured that the Rinnai solution was an ideal system for this project. Having run some capital expenditure, operational expenditure, and carbon modelling, we also saved the school money and reduced its carbon footprint. “

Rinnai’s hot water heating units have been certified by the British Standards Institution (BSI) for use as hydrogen blends ready. The range was subjected to rigorous testing and analysis by the BSI and the product range is ‘Hydrogen BLEND 20% ready’ with the I2HY20 gas category certificate for all its products.

All Rinnai continuous flow condensing water heaters are guaranteed to provide limitless volumes of temperature accurate hot water (in excess of 1500 litres per hour) this is combined with market leading turn down ratios (13-1) and 96% efficiency.

Extensive testing also demonstrates that multiples of its existing ranges are retrospectively compatible with future hydrogen blending including all N series models already installed in the UK.

The Rinnai Sensei N Series continuous flow hot water heater range offers a more compact, enhanced combustion design that allows for easier installation, superior operational performance as well as ease of serviceability.

The Rinnai Sensei N Series is the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK – this gives a greatly extended working life at optimum performance to each of the four models in the range. Added to this are the market leading extended warranties, that accompany the hydrogen Blend-ready and Bio-LPG ready instantaneous water heaters.

The four models are:

-the N1600i giving 954 litres per hour (at 50 degrees)

-the N1600e (external) also giving 954 litres per hour (at 50 degrees)

-the N1300i giving 775 litres per hour

-the N1300e also giving 775 litres per hours of temperature controlled hot water at 50 degrees.

The two 1600s have load profiles of XXL and are water efficiency class A rated, while the 1300s are load profile XL and are also water efficiency class A rated.

All the range is also low-NOx (Less than 26ppm meaning they gain additional points under BREEAM) and the futureproofed continuous flow water heater utilises Rinnai’s patented advanced burner technology with a 13-1 turn down ratio – the largest on the market combined with 96% efficiency rating. Integral controls on the units enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges.

This wide range of modulation means that energy usage is completely optimised as the water heater through smart inbuilt controls will only heat the water to the temperature required thus preserving energy.
