MD wall hung boiler & ATSH indirect water heater

DHW For Smaller Businesses

Refurbishing and modernising heating and domestic hot water DHW for smaller businesses should not be a chore, but commercial boilers can be large and complex to install, especially if available space is limited for new plant. Adveco has responded to this, extending its award-winning MD boiler range with a series of highly compact wall hung variants designed with the smaller plant room in mind.

Smaller business types, from office buildings to light commercial industry, retail and cafés will typically exhibit defined periods of continuous heating and hot water demand across the working day, often encompassing peak periods of demand when energy costs can also be higher. For this reason, to ensure demand is met and energy costs offset, commercial applications will typically look to incorporate thermal storage through indirect heating, using the boiler as the primary energy supply. This is advantageous in terms of maintaining consistent levels of heating or hot water throughout the day, as well as being able to rapidly respond to fresh demands for extra heating. The size of such a system can however prove prohibitive for smaller businesses. While the MD range offers a variety of models to address central heating needs,  Adveco’s MD 15B, 24B and 34B feature connections specified for use with an indirect water heater that can also be used to provide DHW for smaller businesses.

The MD boiler’s single, high-quality patented titanium-stabilised stainless steel heat exchanger, provides exceptional construction strength and corrosion resistance. The brand-exclusive three-pass design features large bore, circular tube cross-sections that reduce the collection of debris for improved operational efficiency and extended operational life. This is further improved by separating the water flowing through the boiler from the business’ DHW supply which is achieved by pairing with an indirect hot water calorifier, such as the extremely compact 160 and 200 litre ATSH Stainless Steel High-Capacity Cylinders. The calorifier vessel includes a single internal high-capacity fixed heating coil at low-level for use with the high-powered MD heat source and adds the option of a secondary electric immersion for built-in system redundancy.

One of the greatest advantages of using this type of indirect tank with an MD Wall Hung Boiler is the consistency of DHW for smaller businesses without requiring the boiler to be in constant use. You, therefore, save on energy, further reducing emissions and are better able to control operational costs. The boiler efficiently heats the water in the tank, which is kept at a consistent temperature for a near-instantaneous supply of hot water as and when needed, steadily distributed throughout the day. Rapid thermal recovery means the system is able to support even the most demanding peak periods which are easily addressed by the built-in controls accessed from the MD’s LCD control screen.

Should business demands increase consistently, the MD is designed with cascade control to enable up to eight units to work together seamlessly, and the ATSH range of calorifiers offers larger vessel sizes for extra DHW load.

Whether providing space heating or DHW for smaller businesses seeking an efficient, cost-effective replacement for ageing gas-fired boilers to support your application, the Adveco range of MD wall hung boilers offer a wide choice of appliances to meet your particular business needs without the need to oversize a system which will be more costly to both install and operate over its lifetime.

FUSION Commercial Hybrid Hot Water Systems from Adveco

  • FUSION is a complete range of low carbon hybrid heat pump and electric hot water systems
  • Resilient stainless steel water heating suitable for all UK regions
  • Compact design for new build and refurbishment projects seeking greater sustainability

Commercial hot water specialist Adveco, introduces the FUSION FPH-S range of low carbon, all-electric, packaged hybrid hot water systems. FUSION harnesses Adveco’s FPi32 Air Source Heat Pumps (ASHP), a high-pressure ATSH calorifier with electric immersion, controls, and metering to provide a reliable, high-temperature, sustainable and cost-effective system for new commercial build and refurbishment projects.

FUSION is available in 16 pre-specified variants with 6 or 10 kW preheat and 9 or 12 kW electric top-up, with capacities ranging from 200 to 500 litres all rated at 10 BAR for high-pressure applications. Able to meet a range of continuous capacity hot water demands from 257-377 litres/hour makes FUSION highly adaptable for a wide range of commercial buildings.

The FPi32 ASHP is specified to supply a working flow of 50°C for system preheat throughout the year, even when ambient air temperatures drop as low as -25°C. Electric immersion top-up then raises system temperatures in the calorifier to the necessary 60°C to meet commercial requirements for safe hot water demands. The stainless steel construction of the ATSH also makes it an excellent all-rounder, resistant to soft water corrosion and, with FUSION’s unique low electric immersion heat intensity (6W/cm²), is more resistant to scale build-up in hard water areas.

The physical design, dedicated controls and integrated metering ensure the ASHP preheat, and immersion work seamlessly to deliver the highest operational efficiencies. This enables FUSION to make the greatest gains possible from the heat pump, even when ambient temperature and system demands fluctuate. These gains offset much of the direct electrical energy usually required, delivering 53% carbon emissions saving and helping control the operational costs of providing business-critical hot water.

“For organisations with small to medium basin and sink led hot water demands and a desire to embrace a more sustainable business model, the FUSION FPH-S range provides a single, easy to accommodate, highly effective response,” says Bill Sinclair, technical director, Adveco. “By choosing one of these packaged hybrid water systems you gain optimum efficiencies, lower your carbon emissions and can be assured building regulations are being met for your commercial project.”
