Gas fired Warm Air Unit – global internet retailer

/in , /by

The life expectancy of a boiler depends very much upon the type of boiler in question but, on average, a traditional gas boiler should last between 10 and 15 years. When it comes to the end if its serviceable life, it’ll need to be replaced – as was the case when we were called to check out some issues a client (global internet retailer) was having with their current heating system at a warehouse in Croydon.

The team at CH Systems discovered that the older gas fired Reznor units had fulfilled their life expectancy and a decision was made to replace the current units with 6no new Reznor UDSA-100 units.

With the roof of the warehouse being 13 meters off the slab, the work had to be carried out on Mobile Elevating Work Platforms (MEWPs) – this was no problem as all of our engineers hold current IPAF Certified Training For Working Height certificates, which enabled us to carry out the work in a much more timely fashion (saving the time and effort of scaffold towers etc).

How innovative installation makes your business energy efficient

/0 Comments/in /by

One of the biggest energy-related challenges for owners of businesses that operate out of commercial buildings – schools, restaurants, supermarkets, offices, gyms etc. – is finding a heating and hot water system that can keep up with the demand, at a reasonable price. Saving energy, for ethical reasons as well as money-saving targets, is no mean feat. But there are ways…

Thinking outside of the box with innovative installations is one way to cut overheads. Heating manufacturer Vokèra is currently working with UK business owners to reduce usage and costs, as reported by Plumbingmag.com. Two recent projects include the replacement of a 43-year-old oil roof-top boiler with a floor standing modular unit, which enabled the building in question to be heated to temperature in a mere 20 minutes.

Another project saw oil boilers replaced with the energy-efficient CondexaPRO, alongside new insulation, high-efficient glazing and LED lighting; the building now saves almost 980,000 kWh per annum.

Cascade configuration is also a good way to ensure that the output of the heating system meets the demand of a large property. Boilers that have been designed for modular systems will work well in commercial applications. If the demand within the building is high, then all boilers in the system can be working together, but, if the heating requirement drops, each appliance can be individually controlled and turned off to match the lower demand.

Vokèra is just one brand committed to helping business save money with energy efficient installations, there are also others – Worcester/Bosch, Reznor, Vaillant, (to mention a few), which are all committed to making energy efficiency commercially viable for both smaller and larger businesses.

Reznor’s new efficiency condensing heater promises to help businesses cut costs

/0 Comments/in /by

In a time when energy culture is all about carbon reduction and money saving, there is extreme pressure on companies to be as eco-efficient as possible. Matter-of-factly, this can only happen if suppliers and providers rise to the challenge with equal intent – by meeting demand with product. With this in mind, Reznor’s vastly improved RHeco range couldn’t have come at a better time. Designed with business in mind, the systems supplier’s new fully condensing gas fired unit promises to cut overheads by delivering warmth at low cost.

Launched earlier this year, the range features a new primary heat exchanger and an advanced burner with ‘pull through’ combustion and premix technology, which allows for high efficiency condensing heaters that have been developed to deliver thermal efficiencies of up to 109 per cent at minimum load and 100 per cent at full load.

With the system’s advanced technology, the reduction in CO, CO2 and NOx emissions is immense; so much so that RHeco exceeds the requirements of current Building Regulations L2 as well as European norms. The extremely low NOx emissions also enable BREEAM points to be claimed (when applicable). BREEAM sets the standard for best practice in sustainable building design, construction and operation and has become one of the most comprehensive and widely recognised measures of a building’s environmental performance. Credit from BREEAM ranks a building high on the sustainability-o-metre, which, along with energy savings made, offers an extremely favourable payback period.

But RHeca’s money-saving possibilities are not all about its ethical content. RHeca’s heating units are made from high quality, corrosion resistant steel, which informs its durability. The system’s tubular primary heat exchanger reduces thermal stress to ensure improved life expectancy, and due to its advanced burner technology delivers optimum reliability and ease of maintenance. In translation: it’s less likely to break and more likely to last a long time.

Other important features include:

  • Versatile flue options (top or rear connections) for ease of installation.
  • High flow axial fan for a powerful air throw, decreases stratification and improves heat distribution.
  • 5:1 turn down ratio for close temperature control. Reduced temperature gradients help prevent stratification.

Reznor has suggested that its RHeca range is ideal for low carbon buildings, with up to 35 per cent energy saving on replacement heaters. For more detail on the RHeco heating range, visit Reznor.co.uk.
