How the M-Thermal-14B3HB2 differs from M-Thermal-12B3HB2 and M-Thermal-16B3HB2
| Parameter | M-Thermal-12B3HB2 | M-Thermal-14B3HB2 | M-Thermal-16B3HB2 |
|---|---|---|---|
| Heating capacity A7W35 | 12.10 kW | 14.50 kW | 16.00 kW |
| COP at A7W35 | 4.95 | 4.70 | 4.50 |
| SCOP (35 °C) | 4.81 | 4.72 | 4.62 |
| Annual electricity consumption (35 °C) | 5153 kWh | 6013 kWh | 6805 kWh |
| Outdoor unit sound power level | 64 dB(A) | 65 dB(A) | 68 dB(A) |
| Cooling capacity A35W7 | 11.60 kW | 12.70 kW | 14.00 kW |
Choose the M-Thermal-14B3HB2 when the M-Thermal-12B3HB2 (12.10 kW) is too small for the building’s heat loss and the M-Thermal-16B3HB2 (16.00 kW) is more than you need. In return for 2.40 kW more capacity than the 12 kW model, the COP at A7W35 is lower (4.70 vs 4.95) and annual electricity consumption at 35 °C is higher. All three three-phase models share the same indoor module HB-A160/CDS90GN8-B2, 9 kW heater, 1.84 kg of R32 and dimensions; what differs is capacity, efficiency and outdoor unit noise.
What flow temperature does the M-Thermal-14B3HB2 heat pump supply?
In heating mode M-Thermal-14B3HB2 supplies water at 25–65 °C and works at outdoor temperatures from −25 to 35 °C. The higher the flow temperature, the lower the COP: 4.70 at A7W35, 3.65 at A7W45 and 3.00 at A7W55, with heating capacity of 14.50, 14.20 and 13.80 kW respectively.
- Seasonal efficiency: SCOP 4.72 at 35 °C and 3.47 at 55 °C.
- Seasonal space heating efficiency ηs: 185.6 % (35 °C) and 135.6 % (55 °C).
- Annual electricity consumption per the manufacturer: 6013 kWh (35 °C) and 7203 kWh (55 °C).
We agree the flow temperature (underfloor heating or radiators) with you, because real-world efficiency depends on it.
Split air to water heat pump: outdoor unit, hydraulic module and connections
M-Thermal-14B3HB2 consists of the outdoor unit MHA-V14W/D2RN8-B2 and the wall-mounted hydraulic module HB-A160/CDS90GN8-B2, linked by refrigerant piping up to 30 m long. The module already contains a circulation pump, expansion vessel, sensors and protection devices, which means less work on site during installation.
- Piping: up to 15 m without topping up refrigerant, height difference between the units up to 20 m; connections gas 5/8″, liquid 3/8″.
- Water side: connections 1″ / 1″, flow rate 0.70–3.00 m³/h.
- Control and communication: wired controller, mobile app, Modbus RTU, cascade connection.
- Additional heat sources: these can be connected, according to the manufacturer’s datasheet.
Does the M-Thermal-14B3HB2 heat pump make domestic hot water?
M-Thermal-14B3HB2 heats domestic hot water to 20–60 °C and can do so at outdoor temperatures from −25 to 43 °C. The built-in 9 kW electric heater (3 stages) switches on automatically during peak load or in very cold conditions. The specification of this kit does not state a hot water tank capacity, so we select it to match your needs.
Why a heat pump must be installed by a certified specialist
M-Thermal-14B3HB2 uses R32 refrigerant (1.84 kg, CO2 equivalent 1242.0 kg), a fluorinated greenhouse gas. EU regulation requires people working with such equipment to be certified. The regulation states (our translation from the Lithuanian version):
“Natural persons carrying out the activities referred to in points (a), (b) and (c) of the first subparagraph of Article 10(1) shall be certified in accordance with Article 10.”
In practice this means you cannot connect a heat pump yourself: installation, refrigerant charging and servicing must be done by a certified specialist.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
