Baxi 800 830 Combi Gas boiler frequently asked questions

Is the Baxi 800 830 a regular, combi or system boiler?

If you want a combi boiler for your flat or house, the Baxi 800 830 might be an option for you to consider.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce gas usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Should I choose a Baxi 800 830 combi boiler for my house or flat?

Whether this Baxi 800 830 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Baxi 800 830 combi is 30 kW, so which types of property is this Baxi 800 830 Combi boiler appropriate for?

A Gas Safe boiler installer would say that this Baxi 800 830 Combi boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Baxi 800 830 Combi boiler's flow rate is 12 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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.


Where will the Baxi 800 830 fit in my house?

The dimensions of the Baxi 800 830 are 700 mm [H] x 390 mm [W] x 285 mm [D].

Is the Baxi 800 830 a non-condensing or condensing boiler?

We recommend the Baxi 800 830 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Is the combi Baxi 800 830 boiler energy efficient?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

If you decide to install a Baxi 800 830 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Baxi 800 830 has been given a rating of 93% for energy efficiency, equivalent to a SEDBUK "A" rating.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Baxi 800 830 has a rating of "A" for heat and "A" for water.

How long is the warranty offered by the manufacturer for the Baxi 800 830 boiler?

The Baxi 800 830 boiler is provided with a parts and labour warranty lasting 10 years.

Baxi 800 830 Combi Gas boiler frequently asked questions

Baxi 800 830 - a regular, combi or system boiler?

When looking for a combi boiler for your house or flat, the Baxi 800 830 might be a suitable option for you.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Would the Baxi 800 830 combi be a suitable choice of boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Baxi 800 830 Combi boiler be appropriate for given its output of 30 kW?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Baxi 800 830 combi boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Baxi 800 830 Combi boiler's flow rate is 12 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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.


What dimensions does a Baxi 800 830 have?

Baxi’s 800 830 is 700 mm tall, 390 mm wide, and 285 mm deep.

800 830 – condensing or non-condensing?

This Baxi 800 830 is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

What energy efficiency ratings have been awarded to the Baxi 800 830 combi?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would choosing the Baxi 800 830 combi boiler be an environmentally friendly decision? Here's what the figures say.

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 800 830 was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

This European legislation intends to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Baxi 800 830 is "A" for heat and "A" for water.

What warranty do I get if I purchase the Baxi 800 830 boiler?

The parts and labour warranty on the Baxi 800 830 lasts for 10 years.
