A Cost Effective Way to Install AmbiRad High Efficiency Radiant Heating Systems

With ever increasing energy prices, the pressure to make savings has never been more urgent. UK industry, faced with the need to remain competitive against the background of a credit crunch is being increasingly squeezed but it is not all doom and gloom according to Simon Garratt, marketing manager for AmbiRad, particularly when it comes to heating.

Current industry regulations obviously insist that staff cannot work in cold temperatures but with factory and warehouse owners faced with an ever increasing overhead, the temptation is to resort to finding the cheapest heating system available, even though it is rarely the most energy efficient.

Most manufacturers of heating systems are now looking to systems that deliver whole life costs as a way of making real energy savings. Short term, a cheap system might seem the right way to go, but don’t be deceived.

Although paying for more energy efficient heating systems may not be a popular idea in the current economy, it makes tremendous sense when true value is looked at, rather than initial costs.

According to government information, the most reliable indicator of ‘value’ in the construction industry is the relationship between long-term costs and the benefit achieved by the end-user. And when it comes to the heating system, best value is gained from the system that achieves the required functionality at lowest cost when calculated over the whole life of the equipment.

Whole-life cost analysis is an economic evaluation process solely for the purpose of assessing the true cost of constructing and running a building over a period of time, based on the functional requirements of the building. It is effective for new buildings, including design and build projects, and is a pre-requisite for all PFI contracts.

The technique was originally used by the accountancy profession to compare outcomes when income varies over time, using today’s value or net present value as a starting point. Today, the methodology is used widely in many industries, although uptake in the construction industry is ‘quite small’, according to a Principal Consultant at BSRIA.

Using these calculations, modern manufacturers such as AmbiRad, a leader in energy efficient heating systems, have proved that the economies that can be gained from installing radiant are substantial. Savings of between 25 and 60% have been achieved when radiant replaces a traditional boiler and radiator system in a large space building.

It’s a technique that has been in existence for decades. With more and more people seeing the benefits of whole-life cost analysis, its popularity in construction is increasing. Rather than focusing on the cost of installment and payment for the system, it focuses instead on the building’s requirements, how well each solution tackles them and the costs of doing so.

Going cheap might look good in an initial payment. But compare its whole-life cost to that of an energy efficient system, and the difference can be thousands, wasted money that businesses cannot afford to lose.

When considering each building’s needs, it shouldn’t be simplified to just simply ‘the building must be heated’, as the full requirements are far more specific. Value management and value engineering are indispensable factors in finding the more efficient solution.

The system should match the needs of the occupants, as well as the building’s shape and size. This means knowing exactly where and when heat will be needed and how it can best be delivered.

In specifying a heating system, it is important to base requirements on output and functional needs, rather than describing the process by which these will be achieved. This allows for flexibility and perhaps more thoughtful or innovative approaches to a heating solution, one that will fulfil needs over the system’s life. For example, it should respond to alterations in the work pattern, downsizing or expansion.

AmbiRad displayed the genuine energy saving benefits of this method and its heating systems with an example at the RAF Coltishall air base. The four 5,500m2 hangars were used for storage and maintenance of the aircrafts on the airbase, and previously had a highly inefficient high temperature hot water distribution system; it turned to reducing its extensive fuel consumption. The previous distribution losses were enormous and the system was burning fuel without producing much heat. The existing heating system was decommissioned and each hangar was fitted with a continuous radiant tube eating system, operating in four zones.

Following an investigation into the options, taking into account whole-life costing, AmbiRad’s radiant tube heating was found to be the best solution for long-term value. The zoned heating had an unusual advantage on this application, on occasion the cockpit was secured into place using epoxy glue. The aircraft could be positioned in one of the zones and left to run over night to set the glue using the new heating system, whereas with the previous heating the entire system had to be left on to achieve this.

After just a few months of instalment, energy consumption was found to have reduced dramatically. Compared to its previous boiler system, the base saw a substantial reduction in heating costs and emissions reduction. Over a ten year period following the system’s introduction it was calculated that the base would benefit from discounted savings of near £150,000.

This is something that every sector can benefit from. And, with forward thinking companies strongly backing the system, like AmbiRad, there can be nationwide savings of up to millions of pounds. With fuel prices looking to never back down, it is a saving that no one can afford not to make.
