Baxi 400 430 heat only Gas boiler frequently asked questions

Is this Baxi 400 430 boiler a combi, system or regular boiler?

The Baxi 400 430 is a heat only boiler you may wish to consider if you want this type of boiler for your house or flat.

Heat only boilers (often referred to as conventional boilers, standard boilers or regular boilers) consist of a large cold water tank, hot water cylinder with an immersion heater, and a control panel. The cold water tank is often situated in a loft or attic while the hot water cylinder tends to be located in an airing or landing cupboard.

The major advantage of a heat only boiler compared to the more contemporary combi boiler is that it’s possible to run more than one appliance requiring hot water at the same time. With a combi boiler, switching two hot water taps on at the same time will lead to a drop in water pressure, temperature and volume to both points.

Best suited for larger homes, you can program hot water and central heating for times and days that suit you and your family. However, if you forget to set the timer and your hot water cylinder is empty, then you may have to wait up to an hour before you run a bath.

Should I install a Baxi 400 430 heat only boiler in my house or flat?

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

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Baxi 400 430 heat only outputs at a maximum of 30 kW, so which types of property would this Baxi 400 430 heat only boiler be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Baxi 400 430 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.


Baxi 400 430 dimensions

The size of the Baxi 400 430 boiler is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Baxi 400 430 non-condensing or condensing?

The Baxi 400 430 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 the Baxi 400 430 heat only considered environmentally friendly?

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.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing the Baxi 400 430 heat only be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Baxi 400 430 is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use right through to final disposal, with the aim of reducing harmful gas emissions.

The Baxi 400 430 is rated "A".

Is this Baxi 400 430 heat only covered by a warranty?

The Baxi 400 430 boiler has a warranty covering parts and labour costs for up to 5 years after installation.

Baxi 400 430 heat only Gas boiler frequently asked questions

What type of boiler is Baxi’s 400 430 - system, regular or combi?

The Baxi 400 430 is a gas heat only boiler.

If your home has more than one bathroom or you have a large family which uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard 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 temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish 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 and not choose 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.

Is the Baxi 400 430 heat only boiler a suitable choice for my property?

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

This Baxi 400 430 heat only boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

The Baxi 400 430 heat only boiler has an output level of 30 kW, so which types of property would it be appropriate for?

A PlumbProud Gas Safe engineer would recommend that this Baxi 400 430 heat only boiler is suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


The dimensions of the Baxi 400 430 are

The Baxi 400 430 stands at TBC mm tall, TBC mm wide and TBC mm deep.

Is this Baxi boiler non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Baxi 400 430.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

How energy efficient is the Baxi 400 430 heat only?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

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 choosing a Baxi 400 430 heat only boiler for your home be positive for the environment? Let's examine 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 Baxi 400 430 has an efficiency rating of 93% with a SEDBUK grade of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

The Baxi 400 430 has been awarded an ERP rating of "A".

How long am I covered by the warranty for if the Baxi 400 430 breaks down?

Parts and labour charges incurred for repairs made to your new Baxi 400 430 are covered by a 5 year warranty.
