Vaillant EcoFIT Pure 830 - a combi boiler, system boiler or regular boiler?

Suitable for a house or a flat, the Vaillant EcoFIT Pure 830 combi boiler is worth considering if you want a combi boiler.

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

Is a Vaillant EcoFIT Pure 830 combi boiler suitable for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

The output of the Vaillant EcoFIT Pure 830 combi is 30 kW, so which types of property would this Vaillant ecoFIT Pure 830 Combi boiler be an appropriate choice for?

An experienced heating engineer would recommend that the Vaillant EcoFIT Pure 830 combi boiler is a suitable choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This Vaillant ecoFIT Pure 830 Combi boiler's flow rate is 12 L/m.

Like all combi boilers, the Vaillant EcoFIT Pure 830 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.

What size is the Vaillant EcoFIT Pure 830 boiler?

The Vaillant EcoFIT Pure 830 measures 700 mm in height and has a width of 390 mm and a depth of 295 mm.

Is the Vaillant EcoFIT Pure 830 non-condensing or condensing?

The Vaillant EcoFIT Pure 830 is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Is the Vaillant EcoFIT Pure 830 combi environmentally friendly?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

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.

Is the Vaillant EcoFIT Pure 830 combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Vaillant EcoFIT Pure 830 was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, right through to the point of final disposal.

The Vaillant EcoFIT Pure 830 has a rating of "A" for heat and "A" for hot water production.

How long is the warranty offered by the manufacturer for the Vaillant EcoFIT Pure 830 boiler?

The Vaillant EcoFIT Pure 830 is supplied with a parts and labour warranty of 2 years.
