Specifications of boilers for a heat pump
A heat pump supplies water at a lower temperature than a boiler, so the heat exchanger area is the main parameter when choosing.
| Model | Volume | Heat exchanger area | Connection | Material | Max. temperature |
|---|---|---|---|---|---|
| DHW boiler 200 l | 200 l | 1.72 m² | G1″ | SUS304 | 95 °C |
| DHW boiler 320 l | 320 l | 2.87 m² | G1¼″ | SUS304 | 95 °C |
| DHW boiler 500 l | 500 l | 3.35 m² | G1¼″ | SUS304 | 95 °C |
| Bivalent 200 l | 200 l | 1.98 m² + 1.14 m² (solar circuit) | G1¼″ | stainless steel | 95 °C |
How to choose the boiler volume
| Number of people | Volume |
|---|---|
| 1–3 | 200 l |
| 4–5 | 320 l |
| 6 or more | 500 l |
This is a guideline for ordinary consumption. If hot water is needed at several points at the same time, choose a larger volume.
Bivalent boiler or combination tank
A bivalent boiler has a second heat exchanger — for a boiler or solar collectors. It is chosen when the heat pump works together with another heat source.
A combination tank is a DHW tank and a heating buffer in one body: 185+65, 250+80 and 300+110 l. A combination tank replaces a separate buffer tank and frees up space in the boiler room.
Indirect-heating boiler or heat pump water heater
Unlike a heat pump water heater, here the water is heated by the main heating heat pump. A DHW tank is chosen when a heat pump is already installed or is being purchased for heating; if only hot water is needed, Hot Spot is suitable.
FAQ
What boiler volume is needed for a family of 4 people?
Approximately 320 l. For 1–3 people 200 l is enough, for 6 or more — 500 l.
Will a Termojet boiler work with a heat pump of another brand?
The boiler is connected via a G1″ thread (200 l) or G1¼″ (320 and 500 l, bivalent), and the sensor is M12. A Termojet engineer will confirm compatibility with a specific heat pump model.
How much does a 200 l indirect-heating boiler cost?
The price of the 200 l DHW boiler is on the product card above, including VAT, installation not included.
