Industrial‑Grade Greenhouse Heating Coal Fired Hot Water Boiler
Designed for large‑scale horticultural operations, the greenhouse heating coal fired hot water boiler delivers reliable, high‑temperature water for year‑round climate control. Engineered for continuous duty cycles, the unit integrates seamlessly with existing pipework and distribution systems, ensuring uniform heat throughout the growing area while keeping fuel costs predictable.
Application Scenarios
Our coal‑fired boiler is the preferred solution for growers who require:
- Large commercial greenhouses (10,000‑150,000 m²) where natural gas or electricity is scarce or cost‑prohibitive.
- Cold‑climate regions where temperature stability directly impacts crop yield and quality.
- Operations that already have a coal supply chain and need a robust, low‑maintenance heat source.
- Facilities seeking a simple, proven technology that can be serviced by local technicians.
Product Overview
Our unit combines a rugged cast‑iron combustion chamber with a high‑efficiency heat‑exchange core. The design prioritises low thermal loss, quick steam‑up, and ease of maintenance. Key construction elements include:
- Heavy‑duty steel frame with corrosion‑resistant lining.
- Adjustable burners for optimal coal feed rate.
- Integrated safety valve and pressure gauge for real‑time monitoring.
- Modular design enabling field upgrades or capacity scaling.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a customized boiler?
We accept single‑unit orders for pilot projects and larger batches for commercial deployments. MOQ typically starts at one unit, with price breaks from 5 units upward.
Can the boiler be adapted for alternative solid fuels?
Yes. While the standard configuration is optimized for bituminous coal, our engineering team can retrofit the burner and feed system for anthracite, lignite, or processed biomass, subject to a feasibility review.
What is the typical lead time from order to shipment?
Standard models are stocked and ship within 15 – 30 days. Fully customized solutions require 45 – 60 days, depending on the scope of engineering changes and component availability.
What warranty and after‑sales support are provided?
All units come with a 12‑month warranty covering manufacturing defects. Extended warranty options (up to 36 months) and on‑site service contracts are available upon request.
Why Choose a Greenhouse Heating Coal Fired Hot Water Boiler?
- **Cost‑effective fuel**: Coal remains one of the most affordable heat sources in many regions, delivering predictable operating expenses.
- **Robust performance**: Engineered for continuous operation at high loads, the boiler maintains temperature stability even during harsh winter periods.
- **Scalable design**: Modular components allow capacity upgrades without replacing the entire plant.
- **Low maintenance**: Simple mechanical feed and self‑cleaning firebox reduce downtime and spare‑part inventory.
- **Compliance**: Built to meet ISO 9001, CE, and local emission standards; optional after‑treatment systems can further reduce particulates.
