Upgrade with a Highly Efficient Gas Condensing Boiler

A good solution for an energy-efficient renovation of your existing heating system is easiest with the gas condensing technology. A gas heating system warms a house or flat by gas combustion and produces domestic hot water as well.

Among fossil energy sources, gas is the most eco-friendly carrier as it does not leave any residues. Nowadays technology uses the condensing effect, where heat contained in the extract fumes is recovered. This saves up to 30 % of energy, and thus reduce costs.

A reliable heating solution that meets both your individual needs and those of tomorrow

Our new generation of gas condensing boilers provides automatic gas adaptive technology which uses resources more efficiently than ever. This allow you to keep your energy consumption at the minimum level, whatever the quality of the gas supply – good for the environment, good for you. Future-oriented extensions like room-by-room temperature control and smart control functions can also help to generate more savings.

Advantages of choosing a new gas boiler

Gas-fired Condensing System in an Old Apartment

The Foresters, a family of 4, live on the second floor of an old building. Whilst the building has the beauty of high windows and wooden flooring, the old wall-hung boiler is not providing enough hot water to suit the family. They decided that they would need to look for a replacement for their current heating system as the costs of running it were too high and the boiler itself wasn’t performing well enough to meet their high heating and hot water demands.

Once they had spoken to an installer and had them run a full survey of their home, they were advised to replace their current boiler with a modern condensing boiler with a smart controller. This ensures that the family will have enough hot water for everyone's morning showers whilst also helping them keep control of costs.

The goal for the Forester family is to increase the comfort of their home whilst also trying to save money on their energy bills.

  • Following their consultation with an installer, the family were recommended the ecoTEC plus combi. This is a flexible combi boiler offering high performance, control, and efficiency which will fulfil all of the Forester's heating and hot water demands. Not only is the new boiler efficient in gas, the high-efficiency pump within the boiler uses 50% less current than their old one. The precision heating system will help to reduce their fuel bills, and their heating system will also supply sufficient enough heating and hot water throughout the house at any time, delivering hot water within 5 seconds. This new combi boiler can be easily mounted anywhere on the wall, for example in the bathroom or in the kitchen, and is compact enough to suit even smaller properties
  • The Foresters were also recommended the vSMART Control.This self learning smart thermostat becomes accustomed to your household's needs to help improve your boilers overall efficiency, enabling it to work smarter and to minimise the family's energy bills. It can also monitor local weather conditions to adjust the heating to the perfect temperature for the family. The vSMART is also app controlled, allowing the Foresters to conveniently control their homes hot water and heating anytime, anywhere, even via their existing smart home technology.

Gas-fired Condensing System in a Detached Family Home

The Watson family live in a 3 bedroom detached home with 1 bathroom that was initially built around the mid ‘90s. They currently have a combination boiler to provide their heating and hot water however, the boiler is over 10 years old and has needed several repairs in recent years, both increasing the family’s heating bills and inconveniencing family life when repairs are required. Mr. Watson is now actively looking for a replacement to this aging combi boiler, with the aim to find one that will help improve the efficiency of his heating and hot water.

After consulting with an installer, it was decided that the best solution would be a straight combi for combi swap over. This work could therefore be completed by his installer in a day minimal inconvenience for the family.

The goal for the Watson family is to replace their existing old boiler with a newer and more efficient model

  • Mr. Watson calls an installer who recommends a new Vaillant ecoTEC exclusive combi boiler. This offers the highest levels of performance, control, and most importantly, efficiency. Vaillant’s unique Green iQ mark exemplifies the ultimate in energy efficiency, with the lowest levels of fuel consumption and running costs. This will therefore provide the Watsons with much greater hot water performance than their current boiler, and should dramatically decrease their fuel bills. This combi boiler increases the cold water temperature from 10 degrees to 14 degrees, meaning the boiler can deliver your hot water more efficiently, saving you energy, and resulting in a saving of over 10% in hot water mode over the course of the year. Mr Watson was astonished to find that this boiler was only around £200 more expensive than the normal equivalent model, whilst saving £30 per month on his heating and hot water. This means that the additional £200 will be recuperated within less than a year.
  • Similarly to the Foresters, the Watsons were also recommended the vSMART Control. This will help the family to maximise their boiler’s efficiency and to give the family remote control over their heating and hot water through both the dedicated vSMART app and any existing smart home apps that the family uses.
