Baxi 600 630 Combi Gas boiler frequently asked questions

What type of boiler is Baxi’s 600 630 - system, regular or combi?

If you’re looking for a combi boiler for your house or flat, then the Baxi 600 630 is one you may wish to consider.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Is the Baxi 600 630 combi boiler from the 600 range a suitable choice for my house or flat?

Selecting the right boiler for your property means selecting 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".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Baxi 600 630 combi is 30 kW kilowatts, so which types of property would this be appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Baxi 600 630 combi would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.

The Baxi 600 630 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Baxi 600 630 Combi boiler's flow rate is 12 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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.


The size of the Baxi 600 630 in millimetres

The size of the Baxi 600 630 boiler is 700 mm tall, 390 mm wide, and 285 mm deep.

600 630 – non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Baxi 600 630.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

How environmentally friendly is the Baxi 600 630 combi?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

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.

Would choosing a Baxi 600 630 combi help the environment? Let’s see what the performance figures suggest.

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 Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and create fewer harmful gas emissions.

The Baxi 600 630 has an ERP Heat rating of "A" and an ERP Water rating of "A".

How long am I covered by the warranty for if the Baxi 600 630 breaks down?

The Baxi 600 630 boiler is covered by a parts and labour warranty of 7 years.

Baxi 600 630 Combi Gas boiler frequently asked questions

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

If you are considering installing a combi boiler in your house or flat, then the Baxi 600 630 boiler is certainly worth investigating.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

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

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

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

A PlumbProud Gas Safe boiler installer would recommend that the level of output from this Baxi 600 630 Combi boiler would make it a suitable installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Baxi 600 630 Combi boiler's flow rate is 12 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

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's dimensions are 700 mm [H] x 390 mm [W] x 285 mm [D].

Is the Baxi 600 630 non-condensing or condensing?

Condensing gas boilers like the Baxi 600 630 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

What energy efficiency ratings have been awarded to the Baxi 600 630 combi?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Would installing a Baxi 600 630 combi boiler in your home be a green choice? Let's look at the numbers.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Baxi 600 630 was awarded an efficiency rating of 93% with a SEDBUK grading 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.

How long is the warranty period on the Baxi 600 630 combi boiler?

A parts and labour warranty of 7 years is included with the Baxi Baxi 600 630 boiler.
