Vaillant ecoTEC Plus 435 heat only Gas boiler frequently asked questions

Is the Vaillant EcoTEC Plus 435 a combi boiler, system boiler or regular boiler?

Vaillant’s EcoTEC Plus 435 is one you might consider if you’re looking for a heat only boiler for your house or flat.

Heat only boilers, also known as regular or conventional boilers, need enough space for a hot water cylinder with an immersion heater (usually found in a landing cupboard) and a cold-water tank (usually found in a loft). The hot water cylinder keeps water warm and the cold water tank stores water that it passes to the hot water cylinder when required or programmed to do so.

You control how your heat only boiler works by programming it to heat water and provide central heating at the times and on the dates you choose. But if you forget to set times and dates and your hot water cylinder is empty, you may have to wait up to an hour before you have hot water again in your home.

Heat only boilers are often the best choice for a larger family or a property with multiple bathrooms as, unlike with combi boilers, there is no drop in water pressure, temperature or volume when more than one person wants hot water.

Is a Vaillant EcoTEC Plus 435 heat only boiler right for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Vaillant EcoTEC Plus 435 heat only boiler has an output of 35 kW, so which types of property would it be most appropriate for?

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How large is a Vaillant EcoTEC Plus 435 boiler?

The Vaillant EcoTEC Plus 435's dimensions are 600 mm [H] x 375 mm [W] x 340 mm [D].

Is the Vaillant EcoTEC Plus 435 condensing or non-condensing?

We recommend the Vaillant EcoTEC Plus 435 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Does the Vaillant EcoTEC Plus 435 heat only protect the environment?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would choosing a Vaillant EcoTEC Plus 435 heat only help in the fight against climate change? What do the performance statistics suggest?

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Vaillant EcoTEC Plus 435 was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Vaillant EcoTEC Plus 435 scores "A".

How long is the warranty period on the Vaillant EcoTEC Plus 435 heat only boiler?

You receive a parts and labour warranty of 5 years with the Vaillant EcoTEC Plus 435 boiler.

Vaillant ecoTEC Plus 435 heat only Gas boiler frequently asked questions

Is the Vaillant EcoTEC Plus 435 a system boiler, a combi boiler or a regular boiler?

You may wish to consider installing the Vaillant EcoTEC Plus 435 if you are looking for a heat only boiler for your house or flat.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the water temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you want heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like instead of replacing it with a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Should I choose a Vaillant EcoTEC Plus 435 heat only boiler 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 EcoTEC Plus 435 heat only is 35 kW, so which types of property would this Vaillant ecoTEC Plus 435 heat only boiler be an appropriate choice for?

A PlumbProud Gas Safe boiler installer would recommend that this Vaillant ecoTEC Plus 435 heat only boiler is appropriate for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Dimensions of the Vaillant EcoTEC Plus 435 boiler

The Vaillant EcoTEC Plus 435 is 600 mm tall, 375 mm wide, and 340 mm deep.

Vaillant EcoTEC Plus 435 – condensing or non-condensing?

We recommend the Vaillant EcoTEC Plus 435 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

What energy efficiency ratings have been awarded to the Vaillant EcoTEC Plus 435 heat only?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Will you be helping the environment if you decide to install a Vaillant EcoTEC Plus 435 heat only in your home? Let’s look at the figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Vaillant EcoTEC Plus 435 has an efficiency rating of 93% with a SEDBUK grade of "A".

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Vaillant EcoTEC Plus 435.

Am I covered if the Vaillant EcoTEC Plus 435 heat only boiler breaks down?

The Vaillant EcoTEC Plus 435 is supplied with a parts and labour warranty of 5 years.
