Baxi 400 412 - a regular, combi or system boiler?

Suitable for a house or a flat, the Baxi 400 412 heat only boiler is worth considering if you want a heat only boiler.

Heat only boilers, also known as conventional boilers, standard boilers or regular boilers, require a hot water/immersion cylinder and a cold-water tank to work - the immersion cylinder is usually stored in a landing or airing cupboard and the cold water tank in your attic. Your water is kept hot throughout the day by the immersion cylinder.

You can schedule your hot water and heating at set times during the day, but if you forget to set your system and there's no hot water left, you'll have to wait for the immersion cylinder to heat your water for your bath or shower.

A heat only boiler is usually a better option if you have several bathrooms in your home or yours is a large household where there may be continual demand for hot water from different family members - combi boilers are not normally a suitable choice in these situations.

Is the Baxi 400 412 heat only boiler from the 400 range a suitable choice for my house or flat?

Whether this Baxi 400 412 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 400 412 heat only is 12 kW, so which types of property would this model be appropriate for?

Most experienced boiler engineers would recommend this Baxi 400 412 heat only boiler as a suitable option for smaller homes and apartments with no more than up to 10 radiators and one bathroom.

What size is the Baxi 400 412 boiler?

400 412 – non-condensing or condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Baxi 400 412 are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Baxi 400 412 heat only rated as environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

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.

Do the available figures suggest that installing the Baxi 400 412 heat only in your property would be an environmentally friendly choice?

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Baxi 400 412 are 93% with a SEDBUK rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Baxi 400 412 is "A".
