Why condensing heaters may not suit your business

Why condensing heaters may not suit your business

Energy efficiency, low carbon and condensing are the buzz words currently circulating the business sector. So when you search online for energy efficient industrial or commercial heating products you may be bogged down with the number of products on offer, all claiming to save you energy and money. Whether they will provide the results you are looking for or not will all depend on the structure of your building.

Condensing heating systems work by converting flue gases into liquid. It does this by passing the fuel burned and the hot gases over a secondary heat exchanger which then turns the residual heat into additional useable heat – a heat that would be released into the atmosphere and lost when using a conventional warm air heater.

While heaters of this calibre do achieve higher efficiency than standard industrial heating systems, they may not be suitable for your premises and here’s why.

Leaving air temperatures generated by condensing heaters are significantly lower than conventional warm air heating systems. This is acceptable when you have a new building that has been built to the highest specification, using high quality insulation and building materials and taking all measures to ensure that the building operates at its maximum efficiency.

However, consider you have an older building with little or no insulation. Take a small car repair shop, for instance, where the roller doors are open for a large part of the day. This would mean that the leaving air temperature would have to be higher to ensure the building remains at a comfortable working temperature at all occupying times. In turn this means that the condensing heater will have to work harder to achieve a similar temperature, which would result in higher energy usage.

Condensing heaters generate an acidic condense waste that will need to be disposed of correctly via the foul drainage system. In some regions there is a requirement for this to be located at least three metres away from the building. This raises another issue, how will the waste get there? Simple, a pump will be required to pass the waste out of the building and into the foul drainage system. This will increase the cost of an installation.

If you have a high efficiency building this would be worth the extra capital as you could expect to see an ROI in a shorter period of time.

In conclusion, condensing technology is an energy efficient source of heating for any industrial or commercial building, assuming that you have taken all measures to increase the efficiency of your building. For those that haven’t, there are alternative heaters that aren’t condensing available from Combat. These include our warm air ELU unit heaters or our ELG and ELO cabinet heaters, as well as our radiant heating systems, which are now fitted with our high efficiency reflector.
