Vaillant ecoTec Plus 415 Regular Boiler – Review

Are you looking for a regular boiler from one of Europe’s leading manufacturers? Let us introduce you to the Vaillant ecoTec Plus 415 Regular. Here we’ll provide a full rundown of its features, so you can decide whether it’s the right choice for your home.

First, let’s give you a quick overview of Vaillant – the brand behind the boiler. Vaillant is a German manufacturer that has been operating for years. They’re known for being first class innovators, having developed water heaters in the early 1900s (we told you they’ve been around a long time) and the combi boiler over 35 years ago. Vaillant heating systems are top quality, designed with both the consumer and planet in mind.

With ranges to suit all domestic properties, you should have little trouble finding a Vaillant gas boiler for your home. Let’s find out if it’s the Vaillant ecoTec Plus 415 Regular Boiler.

Will the Vaillant ecoTec Plus 415 Regular be suitable for my home?

The Vaillant ecoTec 415 has a central heating output of 15kW and is best suited to smaller homes with up to 10 radiators. If you haven’t already, do a quick count up. It’s the best way to determine the output you’ll need.

You’ll have gathered by now that the ecoTec Plus 415 is a regular boiler. This means it’ll need a hot water cylinder and a cold water cistern in order to supply hot water. If you don’t have a lot of free space in your home, a regular boiler probably isn’t a sensible choice. However, if you are looking to upgrade an existing regular boiler, with a more efficient model, the Vaillant ecoTec Plus 415 should tick all of the boxes.

Vaillant are known for their precision engineering and long life boilers. The ecoTec Plus 415 boasts a premium quality aluminium heat exchanger for increased durability, easy maintenance and the possibility of lower heating bills.

If you are looking for a renewable energy solution, you’ll be pleased to hear that the Vaillant 415 Regular boiler can be installed as part of a solar or heat pump system. This will allow you to reduce your carbon footprint, whilst also benefiting from lower bills.

If your home has more than 10 radiators or you have more than one bathroom, you are going to need a boiler with a higher output. Take a look at the Vaillant ecoTec Plus models with outputs of 18kW, 24kW, 30kW and 35kW. Otherwise, Vaillant also offer the Vaillant ecoTec Plus 412 Regular if you have up to 10 radiators.

For comparison with another brand, check out the Worcester Bosch Greenstar 15Ri. It has a 15kW central heating output like the Vaillant 415 but is slightly more slimline in design, with a dimension of 270mm, compared to 316mm.

Vaillant ecoTec Plus 415 Controls

The ecoTec Plus 415 has a basic control panel, with a large backlit display screen for easy viewing. There you’ll see the boiler’s current operation mode and be alerted to any faults. Use the push-buttons to increase and reduce the temperature settings.

Today all boilers must be compliant with the Boiler Plus regulations, introduced in April 2018. An easy way to ensure the Vaillant ecoTec Plus 415 is compliant is to link it with a smart thermostat. There are several options available, including the Vaillant vSMART thermostat from the brand itself, as well as third-party smart thermostats, like the highly sought after Nest and Hive.

As well as making your boiler compliant, using a smart thermostat (and corresponding mobile app) is a great way to gain more control over your heating settings. Personalise your boiler’s cycles to meet your needs and benefit from greater efficiency.

Vaillant ecoTec Plus 415 Regular Size

The Vaillant ecoTec Plus 415 measures 600x375x316mm. It’s fairly compact in size and has a lightweight design, so there may be the possibility of installing it in a kitchen cupboard. The only way to know is to measure up the cupboard you have available and see if it’ll fit.

If the kitchen cupboard is out of the question, fear not, wall space will do just fine and with a flexible rear flue option, you’ll have plenty of choice for its location. Need a little advice? Our expert engineers are more than happy to help.

Vaillant ecoTec Plus 415 Warranty

Hometree offers a free 5-year warranty with every Vaillant boiler installation. If you want to double this to 10 years, we can arrange this for a small extra charge.

Vaillant ecoTec 415 Energy Efficiency

All boilers must now have an ErP (Energy-related Product) rating, which tells you how energy efficient they are. This was previously known as SEDBUK. The idea is that if you replace an old, inefficient boiler, with a lower ErP rating, for a model with a better ErP, you’ll reduce your carbon footprint, whilst also benefiting from lower energy costs.

We’re pleased to say that the Vaillant ecoTec Plus 415 regular boiler has an excellent ErP rating of 89.3%. This gives it an A-rating overall, and, just like in school, an A is the best you can get.

Verdict – Is the Vaillant ecoTec Plus 415 Regular the best boiler for you?

If you are looking to replace an old, inefficient regular boiler with a newer, more energy-efficient model, the Vaillant ecoTec Plus 415 is definitely worth your consideration.

Although a 15kW central heating output isn’t the highest on the market, if you have fewer than 10 radiators, it’s more than sufficient. There’s little point in paying extra for a higher output model when the Vaillant ecoTec 415 will easily meet your heating demands.

The Vaillant 415 is fairly compact in design, highly energy-efficient and compatible with a number of smart thermostats for enhanced control. We should also mention it is Quiet Mark accredited, so it won’t keep you up at night or wake you up in the morning.

All in all, it’s a first class boiler from a highly reputable brand you can trust. Does the Vaillant ecoTec Plus 415 regular boiler sound like the best choice for your home? Get in touch with Hometree to find out the next steps for installation.
