Ensuring high efficiency‎ with a Condensing Boiler

Condensing / combi boilers are the preferred choice these days due to their efficiency and versatility. Consequently, they use less fuel and have lower running costs than conventional boilers. The main difference between a condensing and non-condensing boiler is the efficient heat exchanger.

When launched initially to the UK market, their popularity suffered because of early teething problems but now these problems have been resolved, condensing boilers are the default choice for both engineers and clients alike.

Condensing boilers turn energy contained within the unit into heat, they then recycle heat without wasting it.

Combi boiler design
The basic mechanism of the condensing boiler is somewhat similar to the traditional boiler, but they make better use of the heat they generate. The heat from flue gases being burned is recycled and can then heat your home for less. Whilst traditional boilers release flue gases in excess of 300 degrees, the condensing boiler uses a secondary heat exchanger to utilise these flue gases again.

How are they different?
A Non-condensing boiler takes air from the room, whereas a condensing boiler will take the air directly from outside the flue. Condensing boilers are up to 99% efficient while non-condensing boilers are only up to 78% efficient, that’s why a condensing boiler may require a higher initial cost, but make more sense in the long-run.

Benefits of condensing boilers

  • Space savings: Combi boilers don’t need a hot water tank and are much sleeker when compared to conventional boilers.
  • Supply reliability: New boilers are fitted with a heat exchanger made from stainless steel, so that they don’t corrode over time.
  • Simple controls: They are really easy to operate. They don’t need a hot water timer, as they automatically produce hot water whenever a tap is turned on.
  • Eco-friendly: Combi boilers can significantly reduce your carbon emission foot print.
