The ecoTEC Pro 30, a boiler suitable for small- to medium-sized homes with up to three bedrooms, one bathroom, and hot water, could be right for you.

Customers are at the forefront of this range. The compact, lightweight design of the combi boiler allows it to be installed in a standard kitchen cupboard. The combi boiler has removable side panels as well as a push-fit flue system. This allows for greater accessibility and ease of installation.

Vaillant ecoTEC pro combi range is extremely efficient and economical to run. These units are equipped with many great benefits, including a fully modulating, low NOx burner/fan for increased energy efficiency, built-in frost protection for added peace of mind during winter months, and increased hot water delivery speed thanks to the Vaillant AquaCOMFORT warm start feature.

Why choose the ecoTEC Pro 30kw model

The ecoTEC pro 30, unlike the 28kW and 24kW versions, has a 24kw heating output as well as a 30kW hot-water output. The Pro 30 is a boiler suitable for homes with three bedrooms and one bathroom. You won’t need to wait for your bath to fill up for 10 minutes.

A system or conventional boiler is better if you want to have a shower and bath at the same time. A boiler’s suitability for your home will depend on how many radiators you have. Due to its 12.7l/m flowrate, the ecoTEC Pro30 can provide hot water to heat up to 15 radiators.

Is the ecoTEC Pro combi 30 right for my home?

Vaillant ecoTEC pro 30 combi boiler is perfect for a mid-sized home with two to three bedrooms and one or two bathrooms. It will work in any loft without a cold water tank and it won’t require a hot water tube to operate.

You may be interested in the pro 28 or 24 versions if you live in a smaller house with only one or two bedrooms. All three models can be used on either mains gas or LPG. Along with Worcester Bosch, Vaillant is a favorite among heating engineers.

How good is the Vaillant ecoTEC 30 pro?

These boilers are high quality and easy to source parts which makes them relatively easier and cheaper to repair. Although the new boiler cost is rather high in terms of value for money, it is a relatively good boiler.

Vaillant ecoTEC 30 Pro dimensions

This Vaillant boiler is 720x440x340mm and will fit in some kitchen cabinets. Whilst it is a relatively compact combi boiler, it isn’t the smallest and we always suggest that you measure up before choosing a particular boiler if you are intending on putting it in a kitchen cupboard.

Vaillant ecoTEC Pro 30 Combi Boiler Price

The Vaillant ecoTEC pro 30 combi boiler is priced at £1,200, including flue, but not including installation. This makes it one of the more costly Vaillant boilers in terms of performance and valiue for money. Most boilers in this price range are premium boilers with over 10 years of warranty. It’s over £300 more expensive than its direct competitor, Worcester Greenstar 4000 30kw combi boiler which is one of the best combi boilers to buy right now.


We love the Vaillant ecoTec pro 30 combi boiler. This boiler is perfect for a small 3 bedroom house. It can handle more radiators than the average 1-3 bedroom house due to that little bit of extra output over the 28kw.
