Interview With Phil Alcock, MD, FRICO UK - Infra Red Heating

In the previous article, we spoke about the types of application (from the weird and wonderful to bog standard installation), the logeivity of such a system and how to calculate the energy savings derived from using infra heating technology.  In this, the last portion of the interview with Phil Alcock, MD of FRICO UK , we discuss the affects of infra red waves on the skin, what sort of sun tan (!) you can expect and we take a brief look at the future of infra red heating....

With regard to the infra red rays won’t it harm the body?

Interesting question actually because apart from you I don’t think I’ve been asked that before.  The facts are that radiant heating is part of the electromagnetic spectrum and it’s infrared and that is not to be confused with ultraviolet which is on the electromagnetic spectrum, but it is a completely different part of the wave length and also it is not to be confused with X-rays and micro waves which are obviously very dangerous.

Infrared is entirely benign and in fact as humans we are designed to feel comfortable with infrared energy and as mentioned previously, any warm surface gives off infrared energy which is perfectly safe.  It is not ultraviolet which is the harmful component of being in the sunshine which is also on a completely different end of the spectrum, in fact conversely infrared is widely known for its health benefits some of which can be overstated, and it’s not a cure all, but the fact that the body is designed to feel comfortable in the infrared energy will indicate that infrared heating is very beneficial.

Most people know that if you sit in an environment you need the air to feel quite warm to feel comfortable.  The humidity has an affect if you are sitting in a damp room the damp has an effect that’s also unhealthy.  You don’t get this problem with radiant heating, as it will heat the structures and prevent the condensation build up.

Plus, there is another health benefit to using infrared energy - there is no air movement. If you have a convection system there is always air movement because you set up a convection pattern – as warm air rises cold air falls to the ground, and that means that dust moves around the room along with anything else unpleasant in the air.  With an infrared system there is no air movement and it is very clean and that is why it is very popular in hospitals – they use a lot of radiant heating because they are concealed, meaning there are zero kinds of radiators to collect the dirt or pipe work to clean or nooks and crannies making it a very healthy system. 

So I won’t get a suntan from it then?

I’m afraid not – you might get a warm glow but not a tan!

What is the future for infrared heating?

Our experience is that it is growing all the time, particularly the electric infrared heating systems in the UK, it’s been a gas and radiators market and that is down to tradition more than science. Most people know that fuel costs are rising and gas is rising faster than electricity, and no fuel is cheap nowadays, but well insulated building are favouring systems (if you look at the running costs of a system) that requires no maintenance and is very cheap and easy to install, such as infrared heating.

So in domestic situations there is a move towards this sort of heating - we are also finding more and more use in commercial situations and sports environments, and that is a fast growing market because as you know there is more interest in health and leisure activities right now.

So we find that the uses and applications are growing all the time and we are always going to need heating, certainly in this country, but what we also find is that we can use less heating – the typical house heating load is a fraction of what it was a few decades ago.  Because the products are very flexible and able to fit into many different types of applications, it means infrared heaters can be used absolutely anywhere.

So would you agree because of the advancement of building design and construction that has encouraged this growth in using infrared technology?

Yes absolutely - no system is perfect and there are things to be considered when designing radiant heating systems.  One of the things to consider particularly in a residential and office situation is that you still need enough heat in the building to cover the heat loss, and if the heat loss is very high i.e. in a badly built leaky building, that would mean using a lot of radiant heating.  The problem can then be that it can appear too hot because our bodies can directly absorb the infrared heat coming from a large number of power infrared heaters -  and that was the problem in the past with heating these old badly put together buildings such as warehouses and large halls.

That’s all changed and now building regulations have changed and radiant heating comes in to its own.  One of the things that we bring to the market is having the expertise in how to apply the product to design a radiant heating system.  We have found that you have to be careful not to oversize it rather than undersize it, it is more often the case the system has been oversized and getting too warm than not warm enough. 

So it is important as part of the whole heating package that there is a controls system to make sure the system doesn’t get too hot, and again you need a bit of expertise and experience to design the system and to design it correctly so that it is working as perfectly as a heating system can. 

Thanks for your time Phil.
