Infrared Heating - Discussion With Phil Alcock, MD, FRICO

Contd....Part 2 of Discussion With Phil Alcock, MD, FRICO UK.

Thanks Phil – infrared is becoming more and more popular in yoga studios, gymnasiums, sports halls; do you see any other growth areas where infrared heating can be used?

Infrared heating will provide heat in large areas such as warehouses, churches, sports halls, gymnasiums, which have very large air volume structures and traditional buildings like a warehouse, which is not usually well insulated.  Trying to heat the air space in those buildings is almost impossible or certainly very expensive to do, so radiant heating is better because you don’t have to heat such a huge air space. 

Radiant heating has not been the most obvious option to use, but now with very well insulated properties and at the other end of the scale, living rooms, domestic rooms, offices, yoga studios, most new buildings are now very well insulated - so radiant heating is a very, very effective solution.  Part of the reason for this is that the heat requirement in a well insulated environment is very low.  One of the benefits of using radiant heating is that you can very precisely match the heat loss of the room to the power needed - so in theory if the heat loss is 700W you install 700W of radiant heating.  You precisely match the heat load for that the room.  

Again, the advantage of radiant heating is that you don’t need to preheat the air or to provide a more powerful unit to provide a fast warm up, so you can very precisely match the heat loss.  If the heat loss is low, and for a small room typically it may only be few 100W which is the sort of heat contribution you would get from a couple of light bulbs - a small amount of radiant heating can provide a similar amount of radiant energy and because of that you can hide the radiant heating in parts of the structure.  You can put it in the floor, you can put them in the ceiling or on the wall as decorative panels, so there is a huge amount of possibilities but the main advantage is that you can directly match the heat loss and hide them in the structures very discreetly.

So what with better building standards – the use of infrared heating looks to be a far better alternative to gas central heating?

Yes exactly, and if you class under floor heating systems as radiant heating (which they are) there are an awful lot of new homes using this method of heating, and under floor is a very successful heating system – wet or electric – it is popular mainly because it is very easy to connect to a heat pump.  

Heat pumps are very energy efficient but they are very high capital costs and if you look at domestic radiant heating, it is very low capital costs and absolute zero maintenance.  In fact a lot of radiant heating systems we supply are intended to be largely DIY installed type products, so there is not such a huge level of skill required to install electric radiant heating system  - so it has a low capital cost and it has a low running cost which are just more examples of the advantages of using infrared heating systems – so, the fact is that when placed in a well insulated modern building we can provide heat with very low energy without the maintenance worries and costs.
