Revolutionary heat pump technology

Heat pumps offer heating, hot water and cooling. Environmental heat is the main energy source, and it can be gained through either air, water, or the ground. A heat pump will require an electricity source to operate.

Vaillant offers suitable heat pumps for every energy source. Air-to-water heat pumps are an ideal way to upgrade your heating. These heat pumps can be easily mounted outdoors and are low in acquisition costs.

Your advantages of modernising with a heat pump

Cut your heating expenses significantly

Profit from low operating costs due to the use of free environmental energy.

Enjoy triple comfort: heating, hot water, and in some cases even cooling

Choose your own comfortable temperature, regardless of the outside temperature, all year round

Boiler Upgrade Scheme

The Boiler Upgrade Scheme (BUS) is aimed to encourage homeowners in England and Wales to upgrade their existing heating system to a more energy efficient option, such as a heat pump in an effort to decarbonise their home’s heating.

Financial security due to independency

Being independent of fossil energy prices means that there will be less surprises for you in terms of price fluctuations

What does modernisation with a heat pump involve?

Replacing your traditional gas heating system with a more sustainable heat pump can be a great decision both ecologically and economically. Heat pumps can improve your home's energy efficiency by an additional 250% depending on your home's requirements, helping to lower future energy costs whilst also reducing the environmental impact. However, there is some preparation involved prior to the installation of a heat pump. The first thing you should do is talk to an expert from your local Vaillant heating service provider, who should also handle the replacement of the heating system. Together with your Vaillant installer, you can determine which type of heat pump is most suited for your home based on your home type, family life, and any other additional requirements. This plays a key role in the type and scope of modernisation.

The installation of an air source heat pump can typically completed in one to two days whereas ground source and water source heat pump may take around three to four days due to the excavation and/or drilling work.

Heat Pump in a Detached House

The Smith family have decided to move to a house which was built in 1997 and still has the same heating system installed since it was built. This heating system is a large oil-fired boiler with a high energy consumption.

They are looking to upgrade their heating system to one which will offer a higher level of comfort alongside improving their systems energy efficiency.

Their home is well insulated and has an underfloor heating system, making it an ideal candidate for the installation of a heat pump.

  • The Smith family consulted their local MCS certified Vaillant renewables partner who recommended they install the aroTHERM split air to water heat pump. This heat pump extracts the freely available thermal energy from the outside air and converts this into heating and hot water. This heat pump is made up of two modules; an indoor wall-mounted unit that is approximately the same size as a standard combi boiler, and an outdoor unit which can be either wall-mounted or free standing and can be discreetly installed up to 15m away from the property. Mrs. Smith decides that since the aroTHERM split is extremely quiet, she can have it installed either in the garden or near the wall of the house without having to worry about any problems from the noise. The compact indoor unit of the heat pump is placed next to the washing machine in the laundry room.
  • To complement their new heat pump, the Smith family are also recommended a uniSTOR hot water cylinder to ensure maximum heat transfer and help to both reduce running costs and increase hot water performance. The family can choose from a range of cylinders from 150 to 300 liters, all of which are made using a fully recyclable stainless steel shell and can be supplied pre-plumbed.
  • They are also recommended a VRC 700 wireless system controller to operate their new heat pump, allowing the family the potential to control their heating room by room (with the additional of ambiSENSE radiator valves), and offering app-based control anytime, anywhere. The VRC 700 is also able to adapt the heating output automatically to suit the outside weather conditions, and to further improve the systems energy efficiency, thus helping the family reduce their future energy bills.

Replacing oil heating with an air-to-water heat pump

The dismantling of the old oil heating system is a bit more complicated part because of the removal of the oil tank. The tank has to be completely emptied, cleaned and removed. Make sure to hire a company that not only removes the tank, but also disposes of it for you.

When this is done, the rest of the work - installing the heat pump indoor unit and connecting it to the outdoor unit - is done quickly. You should allow in general one extra day to complete the exchange due to the oil tank removal task.

Watch our video 'Heat pump considerations and expected costs'.

Replacing gas heating with an air-to-water heat pump

Before you can install a new heat pump heating system, the existing gas heating system must first be removed. An experienced heating engineer routinely does this and can carry it out in just a few hours.

The indoor unit of the heat pump can then be installed where the old heating system once stood. This can be either a compact unit with all hydraulic components or several parts.

The indoor unit is connected to the outdoor unit through openings in the exterior wall of the boiler room. With careful planning and professional installation by a qualified company, the exchange should be successfully completed within one day.
