Vaillant ecoTEC Plus 637 System Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoTEC Plus 637?

Vaillant’s EcoTEC Plus 637 is one you might consider if you’re looking for a system boiler for your house or flat.

System boilers need a hot water cylinder to work - normally fitted inside an airing or landing cupboard or similar spot. Unlike heat only boilers, they do not require a separate cold water tank, making them a more suitable choice if you have no loft, lack space in the attic, or are planning to do a loft conversion.

These boilers distribute hot water around your home to your taps and radiators using (often built-in) circulating pumps and they're easier to install as there is one less component (the water tank) to find room for. A system boiler needs to be programmed to tell it what times you want heat and hot water - unlike combi boilers, they don't provide hot water on demand.

Would the Vaillant EcoTEC Plus 637 system be a suitable boiler for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Vaillant EcoTEC Plus 637 system's output at 37 kW, which types of property would this Vaillant ecoTEC Plus 637 System boiler be most appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Vaillant ecoTEC Plus 637 System boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Vaillant EcoTEC Plus 637 dimensions

The size of the Vaillant EcoTEC Plus 637 boiler is 720 mm high, 440 mm wide, and 406 mm deep.

Is the Vaillant EcoTEC Plus 637 non-condensing or condensing?

The Vaillant EcoTEC Plus 637 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Vaillant EcoTEC Plus 637 system good for the environment?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Would installing the Vaillant EcoTEC Plus 637 system in your home be an environmentally friendly decision? Let's look closely at the figures.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Vaillant EcoTEC Plus 637 was given an efficiency rating of 94% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The Energy Related Products (ERP) Directive's aim is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Vaillant EcoTEC Plus 637 is "TBC".

What warranty does the Vaillant EcoTEC Plus 637 system boiler come with?

On the Vaillant EcoTEC Plus 637, the manufacturer offers a parts and labour warranty of 5 years.

Vaillant ecoTEC Plus 637 System Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoTEC Plus 637 - regular, system or combi?

You might want to consider the Vaillant EcoTEC Plus 637 for your house or flat if you are looking for a system boiler.

Like regular boilers, system boilers have a control panel that you use to program the times of the day when you want hot water to be available or the central heating to come on, such as in the morning when several people will be having showers or baths.

Once the water is heated, it is stored and kept warm in a hot water cylinder during the hours you've programmed. Hot water cylinders are often installed in an airing or landing cupboard and they contain built-in circulating pumps whose job is to heat water drawn from the mains.

System boilers do not need a cold-water tank like heat only boilers, making them a popular choice for homeowners who want to save space and those who are considering a loft conversion in the future. They're also easier for heating engineers to install, as they require one less large part. Instead, they use built-in circulating pumps.

Would the Vaillant EcoTEC Plus 637 system be a suitable boiler for my house or flat?

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.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Vaillant EcoTEC Plus 637 system is 37 kW kilowatts, so which types of property would this be most suitable for?

To most experienced Gas Safe boiler installers, the Vaillant EcoTEC Plus 637 system EcoTEC Plus would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is the Vaillant EcoTEC Plus 637 boiler?

The Vaillant EcoTEC Plus 637's dimensions are 720 mm [H] x 440 mm [W] x 406 mm [D].

Is the Vaillant EcoTEC Plus 637 a non-condensing or condensing boiler?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Vaillant EcoTEC Plus 637.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

How energy efficient is the Vaillant EcoTEC Plus 637 system?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Will choosing to install a Vaillant EcoTEC Plus 637 system in your home help the environment? Let's review the figures.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Vaillant EcoTEC Plus 637 are 94% with a SEDBUK rating 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 637 has a rating of "A".

If the Vaillant EcoTEC Plus 637 breaks down, will I be covered by the warranty?

The parts and labour warranty on the Vaillant EcoTEC Plus 637 lasts for 5 years.
