How a Commercial Boiler Works

It’s hard to imagine a world without the humble boiler. After all, everything from your radiator to your hot water relies upon it, whether you’re operating a commercial boiler in Hampshire or a domestic boiler in the Outer Hebrides. There are three main types of condensing boiler for commercial boiler and domestic boiler use, with the combi boiler becoming an increasingly popular choice across Hampshire and the rest of the UK. Regular boilers and system boilers are also used. While there are differences in the design of each condensing boiler, they operate according to the same basic principles. Let’s take a look at these.

Burning the Gas commercial boilers

From Hampshire to Hertfordshire, condensing boilers are the same as standard gas-fired boilers in the most simple of operational principles. In other words, gas is pumped into the boiler and ignited to heat your home or business. So far, so ordinary, but it’s what is done with the rest of the process that makes condensing boilers so efficient as commercial boilers, as well as domestic ones.

When natural gas is burned, hydrogen and carbon dioxide gases are created. In a conventional boiler, these by-products travel through the flue to the outside world, with up to 30% of their heating energy going with them. Condensing boilers capture these gases before they can escape, using a heat exchanger to turn them back into a liquid known as condensate. This condensate is then sent back. In the process, heat that would have been lost is recovered, allowing your condensing boiler to operate at up to 98% efficiency in some cases.

Disposing of Waste  commercial boilers

Once the heat has been used, the remaining acidic condensate waste naturally needs to go somewhere. With this in mind, condensate boilers have pipes specifically designed to remove this waste into a drain. Although acidic, the disposal of this waste is still better for the environment then losing the gases through the flue. Think of the condensate pipe as the equivalent of a car exhaust.

What Condensate Boilers Are Made From

Due to the acidic nature of condensate, condensing boilers are typically made from non-corrosive metals such as stainless steel or aluminium. This makes condensing boilers much tougher than conventional boilers. Condensing boilers are now a legal requirement across the UK. Companies such as KMH Gas can offer further information on the nature of these commercial boilers, as well as tips on how to maintain and service them.
