“Seamless experience and very professional. Would highly recommend. Altaf & James were super polite and arrive at the time they said they would to install. James explained all we needed to know before he left & they took all the rubbish with them!!”

Questions & Answers
What efficiency gains can I expect from an Immergas heat pump?
Immergas units use inverter-driven compressors and R32 refrigerant to achieve coefficients of performance (COP) up to 4.6, meaning they produce up to 4.6 kW of heat for every 1 kW of electricity consumed—often cutting running costs by 60–75% compared to traditional electric systems.
Will an Immergas heat pump perform reliably in very cold weather?
Yes. All models include frost-protection logic and electric-element backup, allowing operation down to around –15 °C, so you’ll continue to get hot water and warm your home even in sub-zero conditions.
How loud are these units in everyday use?
Thanks to “silent mode” and acoustically insulated components, outdoor noise can drop to as little as 35 dB(A)—quieter than a normal conversation—making them ideal for residential locations.
What warranty and maintenance should I plan for?
Immergas heat pumps typically come with a two-year parts warranty (contact your installer for exact details), and we recommend an annual service—cleaning filters and coils—to maintain peak efficiency and protect against scale or corrosion.
