Baxi 400 424 heat only Gas boiler frequently asked questions

What type of boiler is Baxi’s 400 424 - system, regular or combi?

The Baxi 400 424 may be worth considering if you are looking for a heat only boiler for your house or flat.

You may hear a heat only boiler described as a standard boiler, a regular boiler, or a conventional boiler but the terms mean the same. Heat only boilers require a hot water cylinder (usually stored in a landing or airing cupboard) and a cold water storage tank (usually stored in the loft) to operate. Your water is kept warm by the hot water cylinder throughout the day.

A heat only boiler lets you schedule the hot water and central heating you want for set times of the day. However, you'll have to wait before having a bath or shower if you forget to set it and there's no hot water left in the tank.

If you have a bigger family or more than one bathroom, a heat only boiler is a better option than a combi boiler in many cases. This is because a combi boiler struggles to maintain water volume, pressure and temperature to multiple points in a home simultaneously.

Is a Baxi 400 424 heat only the right boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Baxi 400 424 heat only's output at 24 kW, which types of property would this Baxi 400 424 heat only boiler be most appropriate for?

To most boiler engineers, the Baxi 400 424 heat only 400 would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What are the proportions of a Baxi 400 424 boiler?

The Baxi 400 424 is 625 mm [H] by 370 mm [W] by 270 mm [D] in size.

Is the Baxi 400 424 a condensing or non-condensing boiler?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Baxi 400 424 is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

How does the Baxi 400 424 heat only boiler rate environmentally?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would choosing the Baxi 400 424 heat only be an environmentally-friendly choice? If so, let's look at its performance 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 400 424 has an efficiency rating of 93% with a SEDBUK grade 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 Baxi 400 424 has an ERP rating of "A".

Baxi 400 424 heat only Gas boiler frequently asked questions

Baxi 400 424 - a system boiler, regular boiler or combi boiler?

The Baxi 400 424 is a heat only boiler you may wish to consider if you want this particular type of boiler for your house or flat.

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.

Should I install a Baxi 400 424 heat only boiler in my house or flat?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Baxi 400 424 heat only is 24 kW, so which types of property would this Baxi 400 424 heat only boiler be appropriate for?

A Gas Safe boiler installer would say that this Baxi 400 424 heat only boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Baxi 400 424 size

The Baxi 400 424 boiler measures 625 mm [H] x 370 mm [W] x 270 mm [D] in size.

Baxi 400 424 – condensing or non-condensing?

The Baxi 400 424 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.

How does the Baxi 400 424 heat only rate environmentally?

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.

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.

Will installing a Baxi 400 424 heat only be a positive contribution to the environment? Let's see what the experts say.

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 400 424 is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

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 Baxi 400 424.

What is the warranty period for the Baxi 400 424?

You receive a parts and labour warranty of 5 years with the Baxi 400 424 boiler.
