HB-200 frequently asked questions

What is the minimum order quantity for the HB-200?

Heatlyt supplies the HB-200 on a 20ft container minimum order, and models can be mixed within one container — buffer tanks, DHW cylinders and duo tanks together — so distributors can balance stock across the range. Quotes are issued FOB Shanghai, and production takes about 30 days from order confirmation and deposit.

Which certifications does the HB-200 carry?

The HB-200 is built in an ISO 9001:2015 certified factory, carries CE marking for the European market, and ships with the ErP energy label shown above. The SUS304 body is joined by argon-shielded welding, the process that keeps a weld seam's corrosion resistance close to that of the parent steel.

What are the HB-200's dimensions and shipping weight?

The HB-200 ships packed at 60 × 60 × 158 cm, weighing 39.5 kg net and 41.5 kg gross. The dimensional drawing above gives connection positions and heights. Those packed dimensions are the figures container loading plans are built from, so they are the ones to quote when calculating a 20ft container load.

What size heat pump does a 200 litre buffer tank suit?

Buffer volume is sized from the heat pump's output and its defrost demand rather than from the floor area of the building — modern air-source units need roughly 2–4 litres of stored water per kW of capacity for a reliable defrost cycle. Heatlyt's buffer tank sizing guide maps that calculation across the HB range.
