How should a 3.5 million kcal gas hot water boiler be selected?
A 3.5 million kcal gas hot water boiler is approximately equal to 4.07MW. In practical selection, the boiler capacity is usually matched with the heating load, water supply temperature, return water temperature, system pressure, altitude, fuel type and emission requirements.
For this inquiry, ZOZEN can transfer the project information to the sales email for follow-up. Customers may send technical requirements to info@zozen.com, or contact ZOZEN by WhatsApp +86 18861589035 and WeChat +86 13506150756. If the project is for the Chinese market, customers can also call 400-161-0099 or 13861509153.
A 3.5 million kcal gas hot water boiler can be configured as a gas-fired hot water boiler system with burner, control cabinet, circulating pump, water treatment device, economizer or condensing heat recovery unit, valves and instruments. If the customer needs shorter on-site installation time, a skid-mounted or integrated system can also be evaluated according to the site conditions.
Before quotation, ZOZEN usually confirms the heating medium, operating pressure, gas composition, expected delivery date, installation country and whether local certification documents are required. These details help provide a more accurate technical proposal and equipment list.
