Unvented Cylinders Experience Dramatic Growth In Demand From Refurb Market

Unvented cylinder systems are now experiencing an unprecedented growth in the replacement market, as many installers recognising that a combi system isn’t always the best choice.

Since figures published by the Hot Water Association in 2008, showed that mains pressure hot water systems, reached close to half of the total hot water storage market, for the very first time, the growth has continued as changing demands favour the benefits offered by unvented systems.

Whilst combi systems can provide an instantaneous hot water solution, very few can exceed 20 litres per minute, or cope with demand from multiple outlets.

McDonald Engineers Sales Director, Jamie Stewart, explained ” Modern households are expecting their hot water systems to be capable of delivering more hot water, at higher flow rates, simultaneously to multiple outlets and with limited loss of performance.”

He continued, “As a result we have seen enquiries for  our POWERflow 2000 unvented cylinder rise considerably from installers, house builders and local authorities who are beginning to question the attractiveness of the combi system.  We have also seen a dramatic increase in sales of  our THERMflow Thermal Storage Unit.  This gives the benefits of Mains Pressure Hot Water at the tap, but with a Vented Store.  This type of unit is ideal for all boilers and can also be used when people have an additional Solid Fuel heat source.”

Taking Alternative Fuel Hot Water Solutions To A New Level

McDonald Engineers has been at the forefront of hot water systems for decades and, as well as an extensive range of products available for immediate despatch,  have established a reputation in the market place, for being the specialists in bespoke hot water cylinders for multi-fuel and alternative fuel applications.

So when a specialist contractor was developing a pre fabricated toilet and wash block for a project being shipped to Africa, which needed to heat the water by burning the waste from the toilets in an incinerator, McDonald Engineers was their first port of call.

With the African climate requiring a comparatively lower level of hot water storage, McDonalds developed and supplied eight bespoke 75 litre POWERflow 2000 Unvented Cylinders to accommodate the fuel source, using its high performance coils for maximum heat transfer.

McDonald Engineers Project Manager, Dean Morrison, explained “Whilst we have manufactured a large number of bespoke cylinders with a multitude of fuels, from solar thermal to heat pumps, this is by far the most unusual fuel source we have ever worked with.”

He continued, “Most importantly the client is delighted with the end result and it goes to show the flexibility of the company, as well our ability to develop solutions that can transfer the heat from virtually any fuel source.”

Future Proof Your Hot Water System With an Unvented Cylinder

Powerflow Unvented Cylinder

Many architects, installers and end clients are turning to unvented cylinders as a means of future proofing their project, due to the systems’ ability to work with renewable energy sources such as solar and heat pump installations.

An unvented cylinder can be either heated directly by electricity or indirectly from an auxiliary boiler, typically gas or oil fired, and can be linked to a solar thermal or heat pump installation.  When installed with a new generation   condensing   boiler, as   required   under   the   current  Building Regulations,  and connected to a renewable energy source, CO2 emissions and energy consumption are reduced.

With the growing unpredictability of energy prices together with the growing movement towards a renewable energy culture, many are seeing unvented systems as a means of keeping their options open with regards to powering their hot water system.

McDonald Engineers, Sales Directors, Jamie Stewart, explained ” Both solar thermal and heat pump systems require hot water storage, such as an unvented cylinder and the perfect partner for these renewable technologies is a copper unvented cylinder with specifically developed solar or heat pump coils.  Copper gives unrivalled heat transfer and maximises the benefits of solar and heat pumps”

McDonald Engineers’ POWERflow 2000 range is one of the UK’s leading unvented copper cylinder systems and the company’s experience and expertise in producing one-off systems, to meet the exact requirements of a multi-fuel solution, is highly respected in the heating sector.

Jamie continued, “We have been at the forefront of the industry when it comes to designing hot water cylinders that are compatible with solar energy and heat pump solutions. However it’s our unique ability to manufacture for large contracts and for one-offs, to our uncompromising quality standards and unrivalled lead times, that has enabled us to establish our enviable reputation in the UK market place.”
