SSI 1500 Stainless Steel Indirect (Calorifier)

Taking the Indirect Approach to your Heating Needs

The Stainless Steel Indirect (SSI) range from Adveco is designed to serve as an indirect calorifier in domestic hot water (DHW) installations. The unit has no integral burner, instead, it contains a single, high-output internal heat exchange coil situated at low level which heats water circulated over it.

Commercial installations where heat is already being generated, such as light industry, leisure sites, and hospitals are perfect locations for the use the SSI as a method of indirect heating.

Without a directly connected gas supply, and therefore no need for a flue, an SSI indirect calorifier is simpler to install as part of a wider heating and hot water system where the heat is provided by a separate appliance – typically a gas boiler, heat pump or solar collector. The fluid in the coil – which is immersed in the water within the SSI – is filled by heated liquid (water or solar fluid) and the heat then exchanged from the coil into the vessel, hence indirectly heated. The insulated storage tank retains energy longer, permitting hot water production year-round in greater quantities and at a reasonable cost.

Commercial systems should harness the efficiency of the modern boiler for both the heating circuit and the DHW system. This counters requirements for a dedicated boiler to heat the calorifier. During the winter, when the indirect water heater is used for the heating, only a small fraction of the heat is used for DHW. In the summer when the space heating is not needed, all of the heat is used for hot water preparation, so this does mean the boiler needs to be operating year round. There are system advantages to this approach as continuous use of the boiler for DHW helps prevent costly deterioration which can occur if a boiler is idle for long periods. The SSI coil is also easy to remove for cleaning and maintenance purposes.

Available in a range of tank sizes, SSI can also be upgraded at any time with a range of coil options making the design highly modular. There is even the option to add an electric immersion heater, turning the SSI into a direct heating appliance, perfect for cost-effectively building redundancy into a system that could otherwise be reliant on a continuous gas supply.

UK framework sets agenda for building and construction sector to police its carbon emissions

Despite the cited success of reduction of emissions in line with the Government’s Carbon Budgets, we are well aware that much of this success has come from easy wins, such as closing operations at coal-burning power stations. The final push to zero carbon by 2050 is the real challenge, as the gap between effort/expenditure and results narrows.

The clear agenda is to adhere to a course of action that curbs global greenhouse gas emissions so that temperature rise remains ideally below 1.5 degrees Celsius within the established timeframe.

To achieve a state of zero carbon emissions requires those with a significant role in global energy consumption and the associated emissions to come to a consensus agreement on tackling the issue. The building and construction sector is currently responsible for around 30% of global energy consumption, and here in the UK there is encouraging new action to drive an ambitious transformation of the industry with co-ordinated action towards delivering 100% net zero carbon buildings by 2050.

The UK Green Building Council (UKGBC) has developed a framework definition for net zero carbon buildings to begin to provide direction for addressing whole life carbon in the industry and clarity on action to achieve net zero carbon across the UK built sector.

The first phase of this work has set the scope of the work required by the industry which can be accurately measured. The UKGBC has set out two clear approaches, net zero carbon construction, and net zero carbon operational energy. In the coming decade, the intent is to develop and ensure these approaches become enshrined within industry protocols.

To reduce construction impacts the framework proposes a whole life carbon assessment should be undertaken and disclosed for all construction projects to drive carbon reductions. The carbon impacts from the product and construction stages should be measured and then offset at practical completion.

To reduce operational energy use, the framework proposed reductions in energy demand and consumption be prioritised over all other measures. In-use energy consumption should be calculated and publicly disclosed on an annual basis with an increase in renewable energy supply and on-site renewable energy source prioritised. Off-site renewables should demonstrate additionality and any remaining carbon must be offset to achieve net zero using a recognised offsetting framework and the amount of offset used should be publicly disclosed.

The framework has been presented as a starting point, with the next ten years seeing the scope and ambition of the framework increased to encourage greater action.

In the short-term, additional requirements will be introduced to challenge the industry, including minimum energy efficiency targets and limits on the use of offsets.

In the longer term, the two approaches for construction and operational energy will be integrated into a broader approach for net zero whole life carbon, covering all of the emissions associated with the construction, operation, maintenance and demolition of a building.

The Advantages of Packaged Plate Heat Exchangers

The Adveco PPN and PPS ranges are packaged plate heat exchanger systems designed to provide an instantaneous (PPN) or semi-storage (PPS) supply of domestic hot water to a commercial building.

Plate heat exchangers can be employed as a system break between old and new heating systems; used as a separation between systems due to pressure limitations or as an integration with renewables. Consisting of an alternating ‘sandwich’ of thin hollow metal sheets with passageways for different sources of liquid – for example, one with heating water and the other with DHW. The plates keep the fluids separated, and as it spreads across the planes of the adjacent plate heat is exchanged. PPN and PPS appliances support heat transfer capacities from 100 to 600 kW.

Constructed from gasketed stainless steel, Adveco Packaged Plate Heat Exchangers are supplied pre-assembled with pumps, pipework, controls, and valves on a metal skid base. This approach reduces design requirements and on-site assembly time for the M&E installer, supporting simple separation or pressure break systems, as well as systems with different temperature requirements between ‘side one’ and ‘side two’. The proven design guarantees a fast response to changes in the DHWS demand, plus accurate and close temperature control with easy to use purpose-built integrated controls.

Adveco Packaged Plate Heat Exchangers are compact, despite the extremely large surface area for heat exchange, so are easy to locate and access within the plant room for maintenance. Smooth surfaces with high turbulence created by the complex pattern of passageways within the plates help to also create a self-cleaning action for less fouling and scaling.

PPN Packaged Plate Heat Exchanger from Adveco - rear viewWater content is also low (so there is less water to treat periodically) and fast moving under pressure. With no static water bacterial growth within the plate system is virtually eliminated. The gasketed design means the system is also easy to disassemble to clean and maintain.

Critically, the gasketed design ensures there is no cross-contamination between the two fluids, so it is a perfect response when integrating new and old systems. By easily adding extra plates, a system can be expanded to meet the specific requirements of a project or application.

The Adveco PPN and PPS ranges are WRAS approved products that are suitable for use with DHW systems up to 99°C and 6-10 bar.

Catering hygiene starts with hot water

Hot Water and Hygiene go Hand in Hand

For catering managers focussed on ensuring good hygiene remains at the heart of their operation, the provision of 24/7 commercial grade hot water is a critical tool for the delivery of food safety on their premises. Old, inefficient, incorrectly installed or poorly maintained systems can rapidly lead to failure and impact critical daily hygiene protocols such as kitchen washdowns.

The number of businesses sentenced in court for catering hygiene offences has more than doubled since 2013*. Despite the vast majority of businesses working hard to meet their hygiene and safety obligation, the number of firms convicted of offences rose from about 60 in 2013 to 130 in 2016 and has remained consistent since then.

Irresponsible businesses are being held more accountable for poor conduct, and fines for organisations have increased by approximately £5,000 to an average of £7,100 under new sentencing guidelines. 94% of those convicted of food safety and hygiene offences in 2017 received a fine.

As a commercial hot water and heating specialist, Adveco offers unparalleled experience in the design, supply and commissioning of bespoke systems to the restaurant and leisure sectors. We help ensure that a business can rely on a system to meet their critical demands for hot water to address staff and premises hygiene. Additionally, Adveco’s team of designers and warranty service engineers will ensure new or refurbished systems are sustainable, efficient and cost-effective to operate.
