The Vaillant ecoTEC Pro Combi is a simple and smart condensing gas boiler that is suitable for small and medium-sized homes.
Manufactured in the UK, Vaillant’s ecoTEC Pro Combi is designed to deliver the greatest efficiencies and provide small to medium-sized homes with instantaneous heating and hot water. The boiler comes in three heat outputs, has been awarded the Quiet Mark accreditation and can be used with the brand’s range of optional smart accessories to give you ultimate control over your central heating system.
How Much Does this Boiler Cost?
You’ll be looking at spending between £900 and £1,810 including VAT, depending on which heat output is most suited to your home. Vaillant ecoTEC Pro Combi heat output options include 24kW, 28kW and 30kW. As boiler prices vary from one supplier (or installer) to the next, we suggest you shop around to find the most competitive deal. It’s usually best to get quotes on both the boiler and installation because you’ll need to pay the fitting costs as well.
How will I know if this Boiler is Suitable for My Home?
The Vaillant ecoTEC Pro Combi is a combination boiler and, like all boilers of this type, doesn’t need to be installed with any tanks in the loft or a separate hot water storage cylinder. It takes it water directly from the mains, meaning it can supply heating and hot water all by itself. This offering from Vaillant is ideal for small to medium-sized properties, however, it won’t be the best option for homes with more than one bathroom because combi boilers don’t cope well when two showers are running at the same time. If you live in an off-gas area, LPG models can be purchased as well.
To find out if the ecoTEC Pro Combi is the right type of boiler for your home and lifestyle, you’ll need to get some professional advice from a Gas Safe registered engineer. A qualified engineer can also recommend the correct heat output to ensure the boiler meets your heating and hot water demands.
Is it a High Efficiency Boiler?
Not only is the ecoTEC Pro Combi a high-efficiency boiler but it has been endorsed by the Energy Saving Trust and meets strict energy performance criteria. It actually has an ErP A rating for heating and hot water efficiency, meaning it is economical to run and will help save you some cash on your fuel bills. The boiler features a modulation ratio up to 1:4, enabling it to automatically reduce its heat output when it senses your home requires less heat. You can also choose to enhance both comfort and efficiency levels by selecting from a range of Vaillant optional controls, such as the VRT 350 wired or wireless control and the vSMART controller and app that allows you to control everything from a smartphone or tablet.
Does this Boiler have a Good Range of Controls and Features?
Yes. It has a bright display to enable you to operate the boiler with ease and all of the essential switches like an on/off button and heating and hot water temperature controls. The ecoTEC Pro Combi comes with built-in two-stage frost protection to ensure it performs all year round and has removable side panels for hassle-free repairs and servicing. It even has an exclusive AquaComfort system that provides quick delivery of hot water to prevent unnecessary wastage. There’s also a range of premium parts including a stainless steel heat exchanger to improve reliability and keep the boiler running smoothly and efficiently. On top of all of that, the boiler is Quiet Mark approved because it’s super-quiet whilst in use.
How long is the Warranty on this Boiler?
The ecoTEC Pro Combi comes with a 2-year parts and labour warranty as standard. If you would prefer a longer guarantee, you might be able to upgrade by hiring a Vaillant Advance installer to carry out the installation.
