Common questions
HB-100 frequently asked questions
What is the minimum order quantity for the HB-100?
Heatlyt supplies the HB-100 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-100 carry?
The HB-100 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-100's dimensions and connection sizes?
The HB-100 ships packed at 53 × 53 × 122 cm, weighing 27 kg net and 29.5 kg gross. It carries four G 1" circulation connections and two G ½" sensor pockets, positioned as shown on the dimensional drawing above. Those packed dimensions are the figures to quote when calculating a 20ft container load.
Is a 100 litre buffer tank big enough for a domestic heat pump?
Buffer volume follows the heat pump's output and its defrost demand, not the floor area of the house — modern air-source units need roughly 2–4 litres of stored water per kW of capacity for a reliable defrost cycle. On that basis the HB-100 suits smaller residential air-source installations; Heatlyt's buffer tank sizing guide works the calculation through across the HB range.
