Vaillant ecoTEC Plus 435 heat only Gas boiler frequently asked questions

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

Looking for a gas heat only boiler for your flat or house? Then the Vaillant EcoTEC Plus 435 may be an option you should consider.

Heat only boilers (often called regular boilers, conventional boilers or standard boilers) keep hot water warm in an immersion cylinder (generally installed in a utility room or landing cupboard) and also include a cold storage tank that holds water for heating later.

As with all boilers, you set the times and days you want your hot water and central heating to be on. However, if you forget to program the boiler and there's no water left in the immersion cylinder, you may have to wait up to an hour for hot water to return.

A heat only boiler is best for homes with more than one bathroom or a larger family - immersion cylinders store a lot of water and they can deliver water at the same temperature, volume and pressure to multiple points in your home at the same time. This is in contrast to the more popular combi boilers that draw water from the mains and heat it on demand - these types of boiler have volume capacity issues.

Should I install a Vaillant EcoTEC Plus 435 heat only boiler in my home?

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 435 heat only is 35 kW kilowatts, so which types of property would this be most suitable for?

An experienced Gas Safe boiler installer would be likely to recommend that this Vaillant ecoTEC Plus 435 heat only boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.


What are the proportions of a Vaillant EcoTEC Plus 435 boiler?

The Vaillant EcoTEC Plus 435 measures 600 mm in height by 375 mm in width by 340 mm in depth.

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

We recommend that you select a condensing boiler like the Vaillant EcoTEC Plus gas Vaillant EcoTEC Plus 435 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Vaillant EcoTEC Plus 435 heat only an environmentally friendly boiler?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing a Vaillant EcoTEC Plus 435 heat only help the environment? Let’s see what the performance figures suggest.

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 435 are 93% with a SEDBUK 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 a Vaillant EcoTEC Plus 435 heat only boiler?

The Vaillant EcoTEC Plus 435 boiler comes with a parts and labour warranty lasting 5 years.

Vaillant ecoTEC Plus 435 heat only Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoTEC Plus 435 - regular, system or combi?

Looking for a gas heat only boiler for your house or flat? If you are, the Vaillant EcoTEC Plus 435 boiler may be worth considering.

You may hear a heat only boiler being called a regular boiler, a conventional boiler or a standard boiler. With a regular boiler, you need to find room within your property for a hot water cylinder with an immersion heater (usually in a landing cupboard or airing cupboard) and a cold-water tank (usually in the loft). The immersion cylinder is what keeps your hot water warm all day.

With a regular boiler, you schedule your hot water and heating for set times during the day or week, but if you forget to do so and the hot water runs out, you'll need to wait for your boiler to heat enough water before you can have a bath or shower - that can sometimes take up to an hour.

A regular boiler is suitable for homes with more than one bathroom or larger families when there is high demand for hot water. Although combi boilers are the most popular type of boiler in Britain, water pressure, volume and temperature drop if there is simultaneous demand from two or more points - for example, someone running a hot water tap when someone else is in the shower.

Is the Vaillant EcoTEC Plus 435 heat only boiler a suitable option for my house or flat?

Whether this Vaillant ecoTEC Plus 435 heat only boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Vaillant EcoTEC Plus 435 heat only is 35 kW, so which types of property would this model be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Vaillant ecoTEC Plus 435 heat only boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Making space for the Vaillant EcoTEC Plus 435

The Vaillant EcoTEC Plus 435 occupies a space of 600 mm high by 375 mm wide and 340 mm deep.

EcoTEC Plus 435 – non-condensing or condensing?

The Vaillant EcoTEC Plus 435 is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

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

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

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 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 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 EcoTEC Plus 435, the ERP rating is "A".

How many years' warranty does the Vaillant EcoTEC Plus 435 heat only come with?

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