Ningbo Ruihe Intelligent Technology Co., Ltd. manufactures a range of water-heated blanket systems to accommodate different usage scenarios, product designs, and commercial requirements. Our vertical water-heating units provide a configuration for brands seeking a distinct upright main-unit design, while desktop models offer an alternative format for compact product positioning. Portable configurations can be developed for applications where convenient placement, manageable dimensions, and flexible product arrangements are preferred. Depending on the model specification, the system can incorporate AC or DC circulation pumps, mechanical control interfaces, touchscreen operation, or remote-control functionality. This range allows Ningbo Ruihe Intelligent Technology Co., Ltd. to support OEM and ODM projects across multiple product categories without restricting customers to a single housing design or control configuration.
The Vertical Water-Heated Blanket category is intended for product programmes that require an upright main unit with a coordinated water-circulation system. Ningbo Ruihe Intelligent Technology Co., Ltd. can work with customers on housing appearance, product dimensions, control-panel positioning, interface layout, and the integration of the heating and circulation assemblies. The vertical format provides opportunities for differentiated exterior styling and brand-specific product presentation. Depending on the agreed engineering specification, customers can evaluate suitable pump configurations, operating controls, connection arrangements, and user-interface requirements for their target markets. Our manufacturing approach coordinates the main unit with the compatible blanket assembly to maintain consistency between the product's mechanical structure, electrical architecture, and water-circulation pathway.
The Desktop Water-Heated Blanket category provides another configuration for brands seeking a compact main unit suited to desktop-style placement. Ningbo Ruihe Intelligent Technology Co., Ltd. develops desktop water-heated blanket systems with attention to housing structure, component arrangement, accessible controls, and compatibility with the selected blanket. The overall design can be adapted according to customer requirements for external dimensions, control functions, appearance, and packaging presentation. For private-label projects, the desktop format offers flexibility in establishing a recognizable product identity through customized housing details, logos, interface designs, and product documentation. Ningbo Ruihe Intelligent Technology Co., Ltd. coordinates these customization requirements with manufacturing feasibility, assembly procedures, and product verification so that the final configuration reflects the approved project specification.
The Mechanical Water-Heated Blanket category serves customers who prefer a straightforward operating interface based on mechanical knobs or similar physical controls. Ningbo Ruihe Intelligent Technology Co., Ltd. can integrate mechanical adjustment mechanisms into compatible main-unit designs, allowing users to operate designated functions through tactile controls rather than relying exclusively on a touchscreen. Depending on the selected model, mechanical interfaces can be configured around temperature adjustment, operating modes, or other supported functions. The final control arrangement is established through the product specification and engineering review. This product category can be considered for markets where familiar physical controls, clear operation, and practical product positioning are important purchasing considerations. Our development process also accommodates touchscreen and remote-control alternatives for customers seeking different interaction methods or product tiers.
Integrated Manufacturing and Component Coordination
Ningbo Ruihe Intelligent Technology Co., Ltd. combines multiple manufacturing activities within our facility, including plastic housing production, circulation-pump integration, control-board assembly, and blanket manufacturing and assembly. This integrated production model allows our teams to coordinate component specifications and assembly requirements throughout the manufacturing process. Rather than treating the main unit and blanket as unrelated products, we approach the heating system as a coordinated assembly in which the mechanical structure, water pathway, electronic controls, pump performance, and blanket construction must operate according to the agreed design. Internal coordination also supports production planning, component traceability where implemented, assembly consistency, and communication when customers request engineering adjustments.
Our plastic housing manufacturing activities support the production of external enclosures designed to accommodate the internal heating, circulation, and control components. Ningbo Ruihe Intelligent Technology Co., Ltd. evaluates housing dimensions, mounting arrangements, access points, ventilation requirements where applicable, and assembly interfaces against the selected product design. The enclosure must provide suitable space for the internal components while supporting the intended appearance, handling characteristics, and maintenance considerations. Housing design and material selection are reviewed according to the model specification and applicable product requirements. By coordinating the enclosure with the internal component layout, our production team can reduce unnecessary interface conflicts during assembly and support consistent construction across approved production batches.
The circulation pump forms another essential part of the water-heating architecture. Ningbo Ruihe Intelligent Technology Co., Ltd. integrates AC or DC pump configurations according to the requirements of each model, taking account of the specified circulation arrangement, electrical input, physical installation, and intended operating conditions. The pump must be compatible with the water-loop design and the selected heating assembly to support the intended circulation performance. Our engineering and assembly procedures address the connections between the pump, tubing, reservoir or associated water-management components where included, and the blanket circuit. Product-specific checks can be established to assess circulation operation, connection integrity, and the consistency of the assembled system against approved requirements.
Electronic control boards manage the operating functions supported by each water-heated blanket model. Ningbo Ruihe Intelligent Technology Co., Ltd. integrates control boards with compatible heating components, pump assemblies, sensors, switches, and user interfaces in accordance with the product design. Mechanical-knob models, touchscreen models, and remote-controlled models may require different control layouts and electronic configurations. Our production workflow takes these differences into account during component preparation, board integration, wiring, assembly, and functional inspection. Control logic, temperature regulation, operating limits, fault responses, and protective functions must be established and verified according to the applicable design and compliance requirements for each product.
What Our Water Heat Blanket Range Covers
Each model in the family addresses a different placement and control preference rather than a different heating principle. All units share the same closed-loop water circuit, built-in water tank and constant-temperature logic; the differences sit in housing format, pump type, interface and blanket size.

How the Hydronic Circuit Works
A pump moves water from the built-in tank through the heating block and into the blanket hose, then back to the reservoir. Because the heating element and the pump stay inside the main unit, the blanket itself is a passive water channel — the reason the design is described as water and electricity separated.
- Closed loop: the tank supplies a stable water volume, so the loop does not need topping up during normal use.
- Constant temperature: the controller modulates the heating block against the returning water temperature rather than cycling a surface element on and off.
- Gentle warmth: circulating water warms without the moisture-stripping effect associated with dry convection heating.
- Pump choice: AC pumps suit cost-driven programmes; DC inverter pumps reduce running noise for premium and bedroom-focused lines.

We build to a specification agreed with your product team, and most configuration decisions fall into the categories below. Where a requested combination has not been produced before, our engineers review the housing, pump and controller together before quoting.
Power and Pump
AC or DC versions, with DC inverter pump options for low-noise positioning.
Control Interface
Mechanical rotary knob, touchscreen, remote control or combined dual control.
Blanket Format
Single and double sizes, washable surfaces, foldable construction for storage.
Branding
Custom logo printing, colourways and housing styling for private-label ranges.
Critical Specifications We Confirm Before Production
Rated voltage and plug type follow the destination market. Beyond that, the parameters below determine whether a unit performs as intended in the field, and we fix them in the approved sample before tooling is released.
- Temperature range and step size: the lowest and highest settable points, and how many levels sit between them.
- Timer logic: maximum duration and whether shut-off is automatic or user-set.
- Pump acoustics: measured at the working point, since noise is the main differentiator between AC and DC variants.
- Tank capacity and loop volume: matched to hose length and blanket area so heat reaches the far end of the blanket.
- Blanket construction: surface fabric, hose routing, washability and connector durability after repeated coupling cycles.
- Housing footprint: desktop versus vertical, and whether the column detaches for nightstand placement.
Manufacturing and Quality Control
Our Ningbo plant covers nearly 50,000 square metres with an annual capacity above 3 million units, supported by more than 50 injection moulding machines and 12 automated assembly lines. Mould development, injection, assembly and testing run under one roof, which keeps changes to a housing or connector inside a single production chain.
Quality control follows incoming material inspection, in-process monitoring, finished-product testing and pre-shipment inspection. Water-heated units receive particular attention at the leak and electrical-safety stages, because a hose joint or tank seal is the component most likely to affect a customer complaint rate.
- Professional test instruments and inspection fixtures for performance evaluation before shipment.
- More than 30 quality inspectors and over 10 engineers supporting development and inspection.
- Management systems certified to ISO 9001 and ISO 14001, with CB and CE EMC documentation available for the relevant models.
Installation, Use and Maintenance
A water-heated blanket arrives assembled; the user fills the tank, connects the hose to the blanket coupling and selects a temperature. There is no fixed installation, no plumbing work and no refrigerant handling, which keeps the product suitable for retail self-purchase and for gift or promotional channels.
- Place the main unit on a level surface within hose reach of the bed, keeping the tank accessible for filling.
- Route the hose without sharp bends or weight resting on the connector.
- Detach the blanket for washing according to the care instructions; the main unit is not washed.
- Drain and store the loop dry at the end of the season to protect the pump and tank.

Frequently Asked Questions
Is the blanket itself electrically heated?
No. The heating element and pump sit inside the main unit, and warmth reaches the blanket through circulating water. The blanket is a passive water channel, which is why we describe the design as water and electricity separated.
Can we order AC and DC versions of the same model?
Yes. The platform is available in both AC and DC configurations, and the DC inverter pump variant is the choice where low running noise matters most. We confirm the pump, controller and housing combination at sample approval.
What customization do you support?
Custom logo printing, colourways, housing styling, control interface selection and blanket size mix. Mould development is handled in-house, so a new housing shape can be quoted as part of the project rather than sourced externally.
Which certifications apply to the range?
Our management systems are certified to ISO 9001 and ISO 14001, and CB and CE EMC documentation is held for the relevant models. The applicable certificate set is confirmed against the final specification and destination market.
How is the product packed and shipped?
Units ship from Ningbo, close to Ningbo Port, with sea freight as the primary method. Carton specification, artwork and pallet configuration are agreed with the order, and our standard quotation is FOB Ningbo Port.
