Vaillant ecoTEC Pro 24 Review – Great entry-level combi for smaller homes

Vaillant ecoTEC pro combi boiler

The Vaillant ecoTEC Pro 24 is great for smaller homes in the UK. This is Vaillant’s least powerful boiler in the Pro range and would be perfect for homes with 1 bathroom and 2 bedrooms. The low output means that it would be cheaper to run and use less gas than its bigger brothers so if you have a pretty low hot water demand then this would be the ideal Vaillant boiler for your home.

Vaillant ecoTEC Pro 28 Review – Combi for small to medium-sized homes in the UK

The ecoTEC pro 28 combi boiler is one of Vaillant’s best-selling boilers. It is perfect for the average home in the UK so appeals the most with an output of 28kW. This means it can cope with moderately hot water demand in small to medium-sized homes with up to 3 bedrooms. If you have 2 bathrooms you may want to consider the 30kW combi boiler.

Vaillant ecoTEC pro 30 Review – Great combi for medium-sized homes

The ecoTEC Pro 30 combi boiler is the most powerful in the Pro range and can cope with moderate hot water demand in homes with 3 bedrooms and 2 bathrooms. As this is the most powerful ecoTEC pro new boiler costs are higher out of the 3 but if you need the extra power as you use quite a lot of hot water or multiple taps at the same time sometimes, then this would be the best choice.

The Vaillant ecoTEC combi boiler range is fantastic as it offers you a wide range of choices on different sized boilers and outputs. With regards to performance and reliability, they come out very well but these do come at a price. 

The entry ecoTEC Pro boiler range boiler prices start where some of the other boiler manufacturers mid-range boilers finish, such as the Worcester 4000 or Viessmann Vitodens 050-w which are over £200 less with better warranties and better technology such as built-in Wifi. They are also more compact too if you require to install your new boiler in a kitchen cupboard. You can get Vaillant boilers on finance too if you want to spread the cost of your boiler and pay monthly for it.

On the other hand, if you are looking for high-performance boilers with lots of power then these combi boilers are high on the list.

With some of the highest flow rates possible from combi boilers, if you can afford the price tag of one of the more powerful boilers then we think they are one of the best options out there. 

Vaillant vSMART App Thermostats & Controls

The Vaillant vSMART app allows you to connect to your boiler and control your heating wherever you are. If you have chosen to install a new Vaillant boiler in your home for energy efficiency reasons, then the vSMART app is another way of helping to reduce your energy bills.
