Conclusion
In Singapore, only licensed professionals can legally install storage heaters while meeting EMA, PUB, BCA, and HDB requirements. Non-licensed work risks catastrophic penalties (up to SGD 10,000 + jail), safety hazards, and financial losses. Always:

- Submit required permits and certifications.
- Insist on post-installation inspections.
For hybrid systems (electrical + plumbing), ensure both licenses are verified to avoid dual violations. Compliance safeguards your home, wallet, and legal standing in Singapore’s regulated environment.
