How it works

It recovers some of the steam heat from gases against old boilers, but it still depends on combustion and does not represent the ultimate decarbonisation target.

It meets thermal and indoor air needs after reducing demand, through sized, controlled, maintainable systems compatible with decarbonization.

When does it make sense?

  • After reducing loads and defining health and comfort requirements
  • When partial load and year-round performance can be compared
  • With access to commissioning, maintenance and monitoring

How to apply it

  1. 1

    Defining what need resolves "condensation boiler as a transition solution" and establishing a starting situation.

  2. 2

    Compare alternatives and adapt design to climate, use, regulation, affected people and available resources.

  3. 3

    Apply with clear responsibilities, check the actual result and correct unwanted effects.

Potential benefits

Thermal comfort

Healthier indoor air

Lower consumption and power

Limitations and precautions

  • It should avoid long-term blocks in fossil fuels and be compared with demand reduction, clean grids and heat pumps.
  • Nominal efficiency does not guarantee the performance of the entire system.
  • Dimensions, refrigerants, noise, hygiene, controls and maintenance should be evaluated.
