What kind of boiler is the Vaillant EcoTEC Plus 615 - standard, combi or system?

The Vaillant EcoTEC Plus 615 is a system boiler you may wish to consider if you want this particular type of boiler for your house or flat.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Should I install a Vaillant EcoTEC Plus 615 system boiler in my home?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Vaillant EcoTEC Plus 615 system's output level is 15 kW, so which types of property would this Vaillant ecoTEC Plus 615 System boiler be an appropriate choice for?

The dimensions of the Vaillant EcoTEC Plus 615 are 720 mm tall, 440 mm wide, and 338 mm deep.

Is this Vaillant boiler condensing or non-condensing?

We recommend that, if possible, you choose a condensing boiler like the Vaillant EcoTEC Plus 615.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your gas bills, particularly if you're replacing a boiler more than 15 years old.

Is the Vaillant EcoTEC Plus 615 system environmentally friendly?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Let's take a closer look at whether installing a Vaillant EcoTEC Plus 615 system would be a good choice for the environment.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Vaillant EcoTEC Plus 615 was given an efficiency rating of 93% and a SEDBUK grading of "A".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Vaillant EcoTEC Plus 615 has a rating of "A".
