Is the Baxi 400 415 a standard, combi or system boiler?

The Baxi 400 415 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, sometimes known as standard boilers, regular boilers or conventional boilers, are better for homes with multiple bathrooms or larger families where members of your household may need to use hot water at the same time as each other, such as a shower in the bathroom and a hot water tap in the kitchen. This is because, unlike combi boilers, they can handle demand from more than one point at a time with no drop in water pressure, temperature and volume.

Heat only boilers use a hot water cylinder with an immersion heater (normally installed in an airing or landing cupboard) and a cold-water tank (normally stored in the loft).

You program a heat only boiler to provide you with the central heating and hot water you need at specific times of the day, such as first thing in the morning. However, if you forget to set timings and there is no water left in the hot water tank, you may have to wait up to an hour before you have hot water again.

Is the Baxi 400 415 heat only suitable for my house or flat?

Whether this Baxi 400 415 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 Baxi 400 415 heat only is 15 kW, so which types of property would this model be appropriate for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Baxi 400 415 heat only would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

How large is a Baxi 400 415 boiler?

The Baxi 400 415 is 625 mm high by 370 mm wide by 270 mm deep.

Is the Baxi 400 415 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 400 415 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 energy efficient is the Baxi 400 415 heat only boiler?

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.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Will installing a Baxi 400 415 heat only in your home be a positive contribution to the environment? The figures below will tell you more.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Baxi 400 415 has been assigned an efficiency rating of 93% with a SEDBUK rating of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Baxi 400 415 has been given an ERP rating of "A".

If the Baxi 400 415 heat only boiler breaks down, am I covered?

The Baxi 400 415 boiler comes with a parts and labour warranty of 5 years.
