Vaillant aroTHERM plus monobloc heat pump

aroTHERM plus is an air source monobloc heat pump whose entire refrigerant circuit stays sealed inside the outdoor unit. It suits homes moving away from gas, or converting an existing radiator system to a heat pump.

Capacity: 4–15 kW
Energy class: A+++

Being a monobloc, no refrigerant line runs indoors; installation is quicker and no annual leak inspection is needed. It uses R290, a natural refrigerant with a GWP of only 3, so it will not be affected by future regulatory limits.

Because it can produce flow temperatures up to 75 °C, it works with existing radiators and does not force you into underfloor heating. During the survey we calculate the heat loss of the building and show in writing which output between 4 and 15 kW will be enough.

Vaillant aroTHERM pro monobloc heat pump
- 5–15 kW
A compact single fan monobloc heat pump. FSF technology reduces the clearance required around the unit, so it fits narrow gardens and terraces. It keeps A+++ efficiency even at a 55 °C system flow temperature and reaches up to 70 °C for radiator systems.
Vaillant aroTHERM pure split heat pump
- 6–10 kW
A split heat pump using R32 refrigerant, with separate outdoor and indoor units. The indoor unit with integrated cylinder stores up to 250 litres of hot water at 40 °C, enough for a family of four. Heating and hot water are covered by a single system.
Vaillant aroTHERM Split intro heat pump
- 8–16 kW
The entry level split heat pump range, with four outputs: 8, 10, 12 and 16 kW. A model with a built-in back-up heater avoids capacity shortfalls on the coldest days. Units can be cascaded for larger systems.
