Frequently Asked Questions
Which kW model should I choose — 18, 21, or 24?
This depends on the number of simultaneous outlets and your inlet water temperature. As a general guide: 18kW for 2 bathrooms in warm climates, 21kW for 2 bathrooms in colder regions or with rain showers, 24kW for 3 bathrooms or high-flow applications. Contact us for a free sizing consultation.
Does this require a three-phase electrical connection?
Yes. The DHE 18/21/24 operates on three-phase 400V supply. This is standard in most Indian villas, bungalows, and commercial properties. Confirm your property's electrical supply before ordering.
Can this be used in a boutique hotel with 5–8 rooms?
For a small boutique hotel, the DHE 24 can handle peak demand for 2–3 rooms simultaneously. For larger hotels, multiple units or the DHE 27 may be required. We offer project-level consultation for hospitality installations.
How is the DHE 18/21/24 different from the DHE 27?
The DHE 27 is a single 27kW unit designed for the highest central heating demand — typically large villas or hotels needing 3+ simultaneous outlets. The DHE 18/21/24 covers the mid-range of central heating requirements.
