Combi Boiler Market Growth Drivers and Challenges:

Growth Drivers

  • Compact Designs and Energy Efficiency - Residential boilers and heaters consume over half of the users' yearly earnings. This clearly shows the need for cost-effective boilers all around the globe. At present, most of the new combi boilers that are installed in the United Kingdom, utilize less energy and provide the users with an impressive 90-94% efficiency. Combi boilers are now much smaller in size, unlike traditional boilers, which require a hot water cylinder, combi boilers have eliminated the need for any additional storage and hot water cylinder, which makes them perfect to use in compact spaces like a utility room, loft, or even a kitchen closet. Also, if the user decides to include a tank, they can enjoy a higher hot water flow rate.
  • Government Regulations- All across the globe, governments are trying their best to save energy and are promoting sustainability as well. Combi boilers are known to be an energy-efficient solution, which is one of the reasons, users are switching to combi heaters. Additionally, there are several strict government regulations mainly for the control of greenhouse gas emissions, and this has also played a major role in increasing the growth of the combi boiler market.

Challenges

  • Space availability and temperature control- Some combi boiler systems completely depend on the gravitation for functioning properly. For this purpose, the tank has to be placed as high as possible, and usually in the loft. The combi boiler, on the other hand, gets its water from the mains, and if the supply of the mains has low pressure, then the taps and showerheads will lack pressure. This can cause an issue in the system and would prevent it from functioning properly.
  • The growing focus on environmental regulations worldwide, adds to the cost pressure challenging the profitability of the combi boiler market.
  • A combi boiler is not able to work properly in a large house that has several bathrooms and taps, as while using the second tap, the first one has to be stopped. This is mainly because the combi boiler provides only a certain volume of hot water at a time.
