Reply To: Boiler Lifespan Hi all, Had my ideal combi boiler serviced just before xmas, like I’ve done since I’ve had it. This year it had it’s 9th service. Same guy has come round…

£2500 sounds a good price especially if you have the work completed in the summer, prices seem to be cheaper then.

The only other area to consider is if your boiler should have an aluminum or stainless steel heat exchanger.

 

Here are some differences between aluminum and stainless steel heat exchangers: (AI Overview)

• Thermal conductivity

  Aluminum has a high thermal conductivity, which allows for a more compact and lightweight boiler design. 
• Corrosion resistance

  Stainless steel heat exchangers are more resistant to corrosion than aluminum heat exchangers. 
• Water conditions

  Stainless steel is tolerant to a wider pH band than aluminum, making it suitable for more challenging water conditions. 
• Noise

  Aluminum heat exchangers have larger waterways, which means the water doesn’t need to flow as quickly, making the boiler quieter when operating. 
• Weight

  Aluminum is lighter than steel, which can be helpful when installing a large boiler in a space with difficult access.
• Maintenance
  Aluminum heat exchangers are more likely to suffer damage if they are not maintained regularly.

Let us know how it goes as and when you do have your boiler replaced.
