Enamel Heat Pump Tank, Coil Cylinder

An enamel heat pump tank with an oversized coil — heat pumps run cooler than boilers, so the coil has to work harder.

Enamel Heat Pump Tank, Coil Cylinder — description and technical data

Product overview

An enamel heat pump tank with an oversized coil

The enamel heat pump tank from LVJIA is built on the Enameled panel system at our own plant in Dezhou, Shandong. Fit a heat pump to a boiler cylinder and it will underperform, and the cylinder is almost always the reason.

What is an enamel heat pump tank?

An enamel heat pump tank is a bolted tank whose steel panels are fired with a glass glaze at high temperature, so the surface meeting the water is chemically glass rather than metal. It does not rust, it takes no coating and it adds no taste, and the glaze is fused into the steel rather than painted onto it. Panels come in 3 × 1 m; 2 × 1 m; 1.5 × 1 m; 1 × 1 m; 1 × 0.5 m; 0.5 × 0.5 m, and the tank is rated for water between 4 and 100 °C.

Enamel heat pump tank with a large surface area heating coil
Two to three times the coil area of a boiler cylinder.

Why a heat pump needs a different cylinder

A boiler delivers water at 70 to 80 °C, so a modest coil transfers heat quickly on a large temperature difference. A heat pump delivers 45 to 55 °C, which leaves far less difference to work with, and the same coil then takes hours to bring the cylinder up. The answer is more surface area: a heat pump cylinder carries a much larger coil, often two to three times the area, so the pump can dump its output and return to an efficient operating point instead of running long and hot.

How the enamel heat pump tank is built

The panel is pressed from 2 to 4.5 mm steel depending on where it sits in the wall, then enamelled on both faces so the outside is protected as well as the inside. Assembled, the wall section measures 12 mm. Panels bolt together on a sealed joint, and because the glaze is inert the same tank handles potable water, fire reserve and mildly aggressive process water without a change of specification. LVJIA runs the enamel line at Dezhou under ISO 9001.

Testing, standards and certification

Every enamel heat pump tank is filled and held at full head before it leaves the factory, and no joint is allowed to weep. The plant is certified to ISO 9001 and the inspection certificate ships with the order; the full set is on our certifications page. The same specification is published on our Made-in-China storefront, where LVJIA is an audited supplier with a 5.0 store rating on Alibaba, 100% on-time dispatch and a response time under one hour.

Where the enamel heat pump tank is used

  • Air source heat pumps — domestic hot water storage.
  • Ground source systems — cylinder matched to the loop output.
  • Solar assisted systems — twin coil for two heat sources.
  • Small commercial — heat pump hot water for a light commercial load.

How to order an enamel heat pump tank

Pricing for the enamel heat pump tank starts at US$200 per m³, falling to US$180 from 10 and US$150 from 50, FOB Tianjin or Qingdao. The minimum order is one set and lead time is within 15 working days from Dezhou, Shandong. Twin coil versions take a heat pump and a solar or immersion input, which is worth specifying at order rather than later.

Send the capacity you need and the space you have, and LVJIA returns an arrangement drawing with the panel schedule before you commit to anything. Our engineers answer specification questions directly through technical help, and the rest of the range sits on the Enameled water tank page.

Other LVJIA tanks worth comparing

Elsewhere in the enamelled range there is the enamel modular water tank for built-to-size layouts, the enamel rainwater tank for harvested rainwater, the enamel household water tank for household sizes and the enamel biogas tank for aggressive process liquids.

  • The surface is glass. — A glaze fired into the steel at high temperature, so the face meeting the water is chemically glass, not metal.
  • Enamelled both sides. — The outside is protected as well as the inside, which matters in a humid plant room.
  • Bolted panels. — Standard panel sizes: 3 × 1 m; 2 × 1 m; 1.5 × 1 m; 1 × 1 m; 1 × 0.5 m; 0.5 × 0.5 m, so the tank is fitted to the room it has to go in.

Product highlights

Why buyers choose enamelled steel

  • It cannot rust.The wetted face is fired glass, so there is no steel exposed to the water at all.
  • No taste, no coating.Nothing is painted on and nothing leaches, which is why it suits potable duty.
  • Long service life.A fired glaze does not break down the way an organic coating does.
