What is a boiler in a house?
A boiler, or a hydronic heating system, uses a fuel source to heat a fluid – usually water or glycol – which is then pumped through your hydronic heating system to various devices such as radiators, in-floor heating loops, etc. to heat your home.
What is the life expectancy of a residential boiler?
between 10 and 15 years

Should I replace my 20 year old boiler?
Therefore, any central heating system using a boiler that is more than 20 years old is likely to be made significantly cheaper to run by replacing with a condensing boiler. As boilers age – particularly those that are not well maintained – they become less efficient.
Is 30kw boiler enough?
For domestic properties, 35-40kW are some of the largest size boilers available, providing enough power to heat big family homes. You’ll find these outputs across all types of Ideal models, with our 35kW boilers capable of running and heating 15 to 20 radiators.
Is a system boiler better than a combi?
For larger homes with multiple bathrooms, particularly with showers in use at the same time, a system boiler with a large hot water cylinder is nearly always a better option. Bigger combi boilers have been developed to provide lots of hot water, but they can make the heating system less efficient.
What are the disadvantages of a combi boiler?
Because combi boilers take water directly from the mains supply if more than one person is showering simultaneously there can be a decline in water pressure. Older properties with original pipework may not be able to handle the higher pressure water and therefore would not be suitable for a combi boiler.
Can a combi boiler run a 4 bedroom house?

How often should you replace your boiler?
The average boiler lasts around 15 years if well maintained and although a yearly service can improve the lifespan, an older boiler has to work harder to heat your home.
