Making Solar Water Heating Solutions Easy With SOLARsave
Filed under: Renewable Energy Cylinders, Unvented Cylinder, hot water cylinder, solar cylinders
McDonald Engineers has made solar hot water systems easy with its SOLARsave pre-plumbed unit which features a high performance dual coil copper cylinder with all the major components pre-fitted and pre-wired for a quick and easy installation.
Available in vented and WRAS approved unvented cylinders, the SOLARsave unit comes supplied with a Solar Differential Controller pre-plumbed to the solar coil. Simply connect the flow & return and solar sensor from the differential controller, along with a solar expansion vessel and relief valve and your solar system is ready to use.
McDonald Engineers’s Sales Director, Jamie Stewart, said “Whilst we have an extensive portfolio of expert solar installers who recognise the benefits from high quality copper cylinders in solar thermal solutions, we were receiving a growing number of enquiries from plumbing contractors who wanted a complete ‘plumb and go’ solution.”
He continued, ” SOLARsave not only makes the specification of the hot water system simple, the pre-fitted and prewired components dramatically reduce the installation time of the system, making it easy and accessible to a far greater number of installation contractors.”
McDonald Engineers also offers its full range of thermal stores, unvented cylinders and calorifiers now available with solar compatibility.

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
Filed under: Renewable Energy Cylinders, Unvented Cylinder, hot water 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.”
