Vaillant EcoFIT Pure 430 - a system boiler, regular boiler or combi boiler?

If you’re looking for a heat only boiler for your house or flat, then the Vaillant EcoFIT Pure 430 is one you may wish to consider.

A heat only boiler, sometimes called a conventional boiler, a standard boiler or a regular boiler, requires both a hot water cylinder and a cold water tank to operate. Most homeowners keep their hot water cylinder in a landing cupboard or airing cupboard and their cold water tank in the attic. Your hot water is kept warm in the immersion cylinder.

With a heat only boiler, you program your hot water and temperature for set times during the day or week. If you forget to set your boiler or the immersion cylinder runs out of hot water, you may have to wait up to an hour for your supply of hot water to be restored.

A heat only boiler is likely to be the best choice for a home with several bathrooms or a bigger family - the type of household where hot water is in continual demand and more than one person might need it at once. With the more popular combi boiler, there is a maximum amount of water that can be heated and distributed, while pressure, volume and temperature drop if two or more people need hot water at once.

Is a Vaillant EcoFIT Pure 430 heat only boiler appropriate for my house or apartment?

Whether this Vaillant ecoFIT Pure 430 heat only boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Vaillant EcoFIT Pure 430 heat only boiler is 30 kW, so which types of property would this be appropriate for?

A PlumbProud heating engineer would recommend that this Vaillant ecoFIT Pure 430 heat only boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

What is the size of the Vaillant EcoFIT Pure 430?

EcoFIT Pure 430 – condensing or non-condensing?

The Vaillant EcoFIT Pure 430 is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Vaillant EcoFIT Pure 430 heat only boiler good for the environment?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on 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.

Will choosing to install a Vaillant EcoFIT Pure 430 heat only in your home help the environment? Let's review the figures.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Vaillant EcoFIT Pure 430 was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Vaillant EcoFIT Pure 430 has an ERP rating of "A".
