Vaillant aroTHERM heat pump

Comfortplus systems powered by Vaillant aroTHERM air to water heat pumps harvest free energy found in the air outside the building envelope and convert it into all season comfort and convenience.

  • Underfloor Heating
    In winter it circulates warm water throughout pipes encapsulated within the concrete slab floor and radiantly warms your entire home.
  • Underfloor Cooling
    In summer it reverses the process and circulates cool water to provide background cooling.
  • Domestic Hot Water
    All year round it generates enough hot water to meet your entire household demand.

Heat pumps from Vaillant are very quiet, powerful, energy-efficient and environmentally friendly.

  • Low noise level (35dBA @4meters) ensures quiet operation for the comfort of home owners and neighbours.
  • A high level of performance even when its -10°C outside.
  • Ultra energy efficient and compared to a gas-fired system saves the equivalent CO2 emissions reduced by a forest area of around 2,500m2.

Engineered in Germany, Vaillant heat pumps offer world leading quality and reliability. Vaillant have more than 140 years of experience in heating systems, including 40 years in the area of heat pumps.

Grant Aerona3 heat pump

Comfortplus systems powered by Grant Aerona3 is an affordable air to water heat pump option for the single purpose of underfloor heating a medium to large home. The Grant Aerona3 harvests free energy found in the air outside the building envelope, tunring it into warm water for the underfloor system.

 

  • Underfloor Heating
    Warm water is gently and quietly circulated throughout pipes encapsulated within the concrete slab floor and radiantly warms your entire home.

Powered by electricity, the Grant Aerona3 heat pump is using an entirely renewable energy which helps reduce the amount of harmful greenhouse gases being released into the atmosphere and, in so doing, lowers the carbon footprint of the household.

  • Low noise level ensures quiet operation for the comfort of home owners and neighbours.
  • A high level of performance even when its -10°C outside.
  • Ultra energy efficient and compared to a gas-fired system saves the equivalent CO2 emissions reduced by a forest area of around 2,500m2.

Grant Aerona3 heat pumps can deliver over four times the amount of energy for every single unit of electricity used depending on the flow temperature and the climate conditions prevailing at the time. Homes utilising this type of heat generator will obviously have a lower dependency on fossil fuels, making them less susceptible to rising fuel costs.
