What type of boiler is the Baxi 400 415 - regular, system or combi?

The Baxi 400 415 is worthy of consideration if you're looking for a heat only boiler for your flat or house.

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 a Baxi 400 415 heat only boiler suitable for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Baxi 400 415 heat only's output at 15 kW, which types of property would this Baxi 400 415 heat only boiler be most appropriate for?

A PlumbProud heating engineer would recommend that this Baxi 400 415 heat only boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

What size is a Baxi 400 415 boiler?

The Baxi 400 415 has the following dimensions - 625 mm high, 370 mm wide, and 270 mm deep.

Is the Baxi 400 415 non-condensing or condensing?

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?

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

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.

Is the Baxi 400 415 heat only an environmentally friendly choice for your home? Let’s have a look at the figures.

The energy efficiency rating of the Baxi 400 415 is 93% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

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".

Am I covered if the Baxi 400 415 heat only boiler breaks down?

The Baxi 400 415 boiler is provided with a parts and labour warranty lasting 5 years.
