How to share the cost of boiler replacement

Check the original boiler contract, there should be relevant explanations such as service life, and you can complain to the Bureau of Quality and Technical Supervision. Four years should be fine.

Protection of rights during warranty period

During the warranty period, the owner can refuse to replace it. If it cannot meet the use requirements due to design reasons, the expenses shall be borne by the developer.

Cost allocation

If it exceeds the service life, it really needs to be replaced, because the beneficiary of the boiler is the owner, so it is reasonable to share the cost according to the housing area. However, whether this fee can be paid from the housing overhaul fund depends on the relevant local regulations.

The property shall not be cut off from water and electricity.

It is impossible for the property to stop water and electricity on this basis, but there is nothing wrong with not heating.
