Tankless vs. storage
Every buyer asks this before switching. This is the comparison we send to distributors — short enough to read in a minute, complete enough to forward to your own customers. See the tankless vs storage running-cost comparison for the arithmetic and the cases where a storage tank still wins.
| Point | TanklessInstant · our range | StorageTank unit |
|---|---|---|
| Heating method | Heats water instantly as it flows through. No tank, nothing to pre-heat. | Pre-heats water and keeps it stored in a tank until the tap opens. |
| Hot water supply | Unlimited hot water on demand. | Limited to tank capacity (30 L, 50 L…). Once empty, you wait for it to reheat. |
| Energy efficiency | Draws power only while water is running. No standby heat loss. | Reheats continuously to hold its temperature, so it loses energy around the clock. |
| Size & space | Compact and wall-mounted. Fits a small bathroom or an under-sink cabinet. | Bulky tank that needs dedicated floor or wall space. |
| Installation | Vertical, horizontal or concealed — orientation is up to the fitter. | Fixed orientation, more pipework and more planning. |
| Time to hot water | 2–3 seconds. | Wait for preheated water to travel through the pipe to the tap. |
| Maintenance | No tank to clean, so upkeep stays low for the whole life of the unit. | Periodic descaling and tank cleaning. Tanks rust and leak over time. |
| Lifespan | 10–15 years. | 8–12 years. |
| Best for | Bathrooms, kitchens, heating systems, modern homes and hotels. | Older installations and whole-house central heating with lower demand. |
| Cost | Higher purchase price, lower running cost. | Lower purchase price, higher electricity bills. |

Inside the factory
R&D, tooling, production, testing, custom packaging and warehousing — the whole chain runs across our production bases in Cixi and Jiaxing, Zhejiang.
Head office and export team in Shanghai; production bases in Cixi and Jiaxing, Zhejiang — in the middle of China's appliance and bathroom-heater manufacturing belt, 6,500 m² at the main site. Factory audits and showroom visits are welcome by appointment, and we can walk the line with you on video if you cannot travel.
Incoming components checked and issued to the line, batch by batch.
Multiple assembly lines run in parallel with in-line functional checks.
Units are powered and run on aging racks, not just spot-checked.
Function, safety and leak tests recorded per production batch.
Retail packaging and export cartons built to your specification.
Finished goods staged and loaded, with mixed-model containers supported.
Quality control
A heater that fails in the field costs you a customer. So nothing leaves the factory untested — we inspect 100% of production, not a sample.
Showroom & trade shows
Buyers visiting the factory can compare water heaters, taps and heaters side by side — and we take the same range to international trade shows, so you can see it in person before you place an order.
Our water heaters and taps are CE and RoHS compliant; the bathroom heater range holds CCC (China) certification. Test reports and technical files are available on request, and export certification can be arranged with your order.

Buyer FAQ
Straight answers on the six things every enquiry covers — who we are, how we build, how we ship, how you pay, how you brand the product, and what it takes to start.
Four core lines, all produced at our production bases in Zhejiang: best-selling instant water heaters (43 models up to 26 kW), compact & mini point-of-use heaters (20 models, 3.5–6 kW), instant electric hot-water taps (25 models) and multi-function bathroom & desk heaters (17 models). The range is updated regularly against what each market sells.
Head office and export team in Shanghai; production bases in Cixi and Jiaxing, Zhejiang — both inside China's appliance and bathroom-heater manufacturing belt, so components, tooling and skilled labour are on the doorstep. 6,500 m² at the main site. Audits and showroom visits are welcome by appointment, and we can walk the line with you on video if you cannot travel.
Standard models are held in stock, so orders below 1,000 pieces ship within 48 hours of payment. Customised versions — logo, panel colour, retail packaging or a special specification — are scheduled case by case, because artwork, tooling and quantity all change the run. Send us the models, quantities and what needs changing and we reply with a dated plan within one working day.
30% T/T deposit with the order and 70% balance before shipment; a letter of credit at sight is accepted on request. Samples are paid at sample price plus freight, and that sample-to-bulk price difference is refunded against a bulk order of the same model placed within 30 days of receiving the sample.
100% functional testing — every unit is powered and checked before packing, not a sample. Aging racks catch early failures, the water side gets a leak and pressure test, insulation and earth continuity are checked electrically, and inspection data is traceable to each production batch.
Yes — it is our normal way of working. A stable in-house R&D team develops new models, and we customize product appearance, glass-panel colour (black, white, grey or blue), internal structure, function settings, packaging and the user manual to your brand. We manufacture under your brand and never put ours on your product.
Samples start from 1 piece and regular orders from 10 sets per model. Custom panel colour, pattern and logo apply from 100 pieces and printed retail packaging from 1,000 pieces; plug standard and cable length add no extra minimum. The sample price difference comes back on your first bulk order within 30 days of receiving the sample.
Our water heaters and taps are CE and RoHS compliant; the bathroom heater range holds CCC (China) certification. Test reports and technical files are available on request, and export certification can be arranged with your order. Certification for other markets can be discussed at the quotation stage.
Units are built to the mains standard of the destination market: typically 220–240 V with the plug type of your choice, and 110 V versions are available on selected models. Tell us the destination country when you ask for a quotation and we match the plug, cable and rated voltage to it.
