What to be aware of when replacing your old heating system

Your installer will assist you in your search of a new heating system

Which heating system is right for me?

What type of appliance – wall-hung or floor-standing? If you already have a wall-hung system it is wise to choose the same type. The same applies if you have a floor-standing boiler. The benefits for you: You use existing connections and do not require any additional space. This saves you time and money.

The next step is working out your hot water needs: Should hot water be stored in reserve or heated up when it is needed? We explain the difference between the two here:

Converting to condensing heating

Condensing boilers use the energy released in combustion more effectively by also drawing heat from the exhaust fumes. This helps to reduce energy costs and emissions by up to 30%. Construction work is required because of the lowered exhaust temperature:

  • The flue system needs to be adjusted e.g. a plastic pipe must be inserted in the chimney to protect the flue from the moisture in the exhaust fumes.
  • Condensing heating also needs a drain connection to drain off the resulting condensed water.

Your installer will advise you on these modifications and carry them out when replacing your heating.

Since 2015, new standards for heating systems have been required by law to reduce CO2 emissions. With a few exceptions, non-condensing heating systems are no longer permitted. When you replace the old boiler, your installer will offer you a new condensing system.

The latest technology for the Sattlers

Laura and Mark Sattler have recently married and will soon be moving into their own 84 m² apartment. They want to replace the old condensing heating system with a new one. They hope this will give them improved hot water convenience. The heating will be mounted to the kitchen wall and must be particularly quiet and space-saving. As they are often out-and-about, the newly-weds want mobile control over their heating.

They decide on an ecoTEC exclusive, which is the premium solution from the Vaillant gas appliance range. A special benefit of this appliance is that it is self-optimising and can thus work especially efficiently. It also offers the best hot water comfort, just as Mark and Laura had hoped. It is particularly important for the couple that Smart Home technology is already integrated into the appliance and ready to go.
