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

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.
