What type of boiler is Baxi’s 400 412 - system, regular or combi?

If you’re looking for a heat only boiler for your house or flat, you may wish to the consider the Baxi 400 412.

Large family homes and properties with more than one bathroom benefit most from installing a heat only boiler (also referred to as a conventional boiler, a standard boiler or a regular boiler). Heat only boilers require both a cold water tank and hot water cylinder and an immersion heater. The immersion heater heats and keeps the water warm and feeds hot water to taps, radiators and other sources via the boiler.

Tell your boiler the times and days when you want hot water and central heating and it'll be there waiting for you. However, if you forget and there's no hot water left in your tank, you'll have to wait up to an hour before it's ready.

The biggest benefit of a heat only boiler is that, unlike a combi boiler, it’s possible to run two taps with hot water at the same time with no drop in pressure, volume or temperature (a known issue with combi boilers). It also means you can shower and have the dishwasher running at the same time without your water pressure being affected.

Is a Baxi 400 412 heat only the right boiler for 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 400 412 heat only outputs at a maximum of 12 kW, so which types of property would this Baxi 400 412 heat only boiler be appropriate for?

A Gas Safe engineer would recommend that the Baxi 400 412 heat only boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

How large is the Baxi 400 412?

The Baxi 400 412 has the following dimensions - TBC mm high, TBC mm wide, and TBC mm deep.

Is this Baxi boiler condensing or non-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 400 412 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.

Is the Baxi 400 412 heat only environmentally friendly?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing the Baxi 400 412 heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Baxi 400 412 was given an efficiency rating of 93% and a SEDBUK grading of "A".

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 400 412 is rated "A".

What warranty do I get if I purchase the Baxi 400 412 boiler?

The Baxi 400 412 boiler comes with a 5 year warranty for parts and labour.
