Vaillant EcoFIT Pure 630 - a regular, combi or system boiler?

The Vaillant EcoFIT Pure 630 boiler is an option you may wish to consider if you're looking for a system boiler for your house or flat.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Is the Vaillant EcoFIT Pure 630 system boiler suitable for my house or apartment?

Whether this Vaillant ecoFIT Pure 630 System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Vaillant EcoFIT Pure 630 system is 30 kW, so which types of property is this Vaillant ecoFIT Pure 630 System boiler appropriate for?

Most experienced Gas Safe engineers would likely recommend that, at this level of output, this Vaillant ecoFIT Pure 630 System boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

What are the dimensions of the Vaillant EcoFIT Pure 630 boiler?

The Vaillant EcoFIT Pure 630 occupies a space of 700 mm high by 390 mm wide and 295 mm deep.

Is this Vaillant boiler non-condensing or condensing?

The Vaillant EcoFIT Pure 630 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is choosing the Vaillant EcoFIT Pure 630 system boiler environmentally friendly?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would choosing the Vaillant EcoFIT Pure 630 system boiler be an environmentally friendly decision? Here's what the figures say.

The Vaillant EcoFIT Pure 630 has been awarded an efficiency rating of 94% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Vaillant EcoFIT Pure 630, the ERP rating is "A".

How long is the warranty offered by the manufacturer for the Vaillant EcoFIT Pure 630 boiler?

The Vaillant EcoFIT Pure 630 boiler comes with a parts and labour warranty lasting 2 years.
