Baxi 600 630 Combi Gas boiler frequently asked questions

Is the Baxi 600 630 a system boiler, a combi boiler or a regular boiler?

The Baxi 600 630 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Is a Baxi 600 630 combi the right boiler for my house or flat?

Whether this Baxi 600 630 Combi 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 600 630 combi is 30 kW, so which types of property would this model be appropriate for?

Most experienced Gas Safe boiler installers would suggest that the Baxi 600 630 combi boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This Baxi 600 630 Combi boiler's flow rate is 12 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


How large is the Baxi 600 630?

The Baxi 600 630 measures 700 mm tall, 390 mm wide, and 285 mm deep.

Baxi 600 630 – non-condensing or condensing?

We recommend that you choose a condensing boiler wherever possible like the Baxi 600 630 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Is the combi Baxi 600 630 boiler energy efficient?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

If you decide to install a Baxi 600 630 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Baxi 600 630 was awarded an efficiency rating of 93% with a SEDBUK band 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 600 630 is "A" for heat and "A" for hot water.

Is there a warranty on the Baxi 600 630 combi boiler if it breaks down?

Parts and labour charges incurred for repairs made to your new Baxi 600 630 are covered by a 7 year warranty.

Baxi 600 630 Combi Gas boiler frequently asked questions

Is this Baxi 600 630 boiler a combi, system or regular boiler?

The Baxi 600 630 boiler is an option you may wish to consider if you're looking for a combi boiler for your house or flat.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Is the Baxi 600 630 combi suitable for my house or flat?

Selecting the right boiler for your home means choosing a boiler that 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’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Baxi 600 630 combi has an output of 30 kW, so which types of property would this Baxi 600 630 Combi boiler be appropriate for?

An experienced boiler engineer would recommend that this Baxi 600 630 Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Baxi 600 630 Combi boiler's flow rate is 12 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Making space for the Baxi 600 630

The Baxi 600 630 stands at 700 mm tall, 390 mm wide and 285 mm deep.

Is the Baxi 600 630 non-condensing or condensing?

We recommend that you choose a condensing boiler wherever possible like the Baxi 600 630 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Is the Baxi 600 630 combi considered environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Do the figures suggest that installing the Baxi 600 630 combi at your property would help in the fight against climate change?

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Baxi 600 630 was awarded an efficiency rating of 93% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, right through to the point of final disposal.

The Baxi 600 630 has a rating of "A" for heat and "A" for hot water production.

What is the warranty period for the Baxi 600 630?

On the Baxi 600 630, the manufacturer offers a parts and labour warranty of 7 years.
