Common questions
HB-150 frequently asked questions
What is the minimum order quantity for the HB-150?
Heatlyt supplies the HB-150 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-150 carry?
The HB-150 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-150's dimensions and shipping weight?
The HB-150 ships packed at 53 × 53 × 161 cm, weighing 35.5 kg net and 38 kg gross. It shares the 53 cm footprint of the HB-100 and gains its extra 50 litres in height, so the two models load onto the same pallet base. The dimensional drawing above gives connection positions and heights.
Should I specify the 150 litre HB-150 or the 100 litre HB-100?
Buffer volume follows the heat pump's output and its defrost demand, not 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. The HB-150 is the step up for medium-sized installations where the HB-100 leaves too little margin; Heatlyt's buffer tank sizing guide works the calculation through across the HB range.
