Baxi 800 825 heat only Gas boiler frequently asked questions

Baxi 800 825 - a regular, combi or system boiler?

You might want to consider the Baxi 800 825 for your house or flat if you are looking for a heat only boiler.

Heat only boilers (sometimes called conventional boilers, standard boilers or regular boilers) require both a hot water/immersion cylinder (normally in a landing cupboard or utility room) and a cold water tank (normally in the attic). The immersion cylinder keeps hot water warm and the cold water tank holds water which it transfers to the immersion cylinder when required.

You set the times that you need heat and hot water with a standard boiler. Once the water in the cylinder is heated, it can be used throughout the day. However, it takes a while for the water to heat up and so, if you haven't set your system, you will have to wait a while for heat and hot water to come back (normally no more than an hour).

Combi boilers deliver hot water instantly but there is a limit to the amount of water they can heat and distribute at any one time. Heat only boilers are usually better choices if you have a large family or more than one bathroom where more than one person in your household requires hot water at the same time.

Is a Baxi 800 825 heat only the right boiler for my house or flat?

Whether this Baxi 800 825 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 800 825 heat only is 25 kW, so which types of property would this model be appropriate for?

Most heating engineers would recommend this Baxi 800 825 heat only boiler as a suitable option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


The dimensions of the Baxi 800 825 are

The Baxi 800 825's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Baxi 800 825 non-condensing or condensing?

Condensing gas boilers like the Baxi 800 825 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

How does the Baxi 800 825 heat only boiler rate environmentally?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing the Baxi 800 825 heat only boiler be an environmentally friendly decision? Here's what the figures say.

The Baxi 800 825 has been awarded an efficiency rating of 93% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan - this includes during the manufacturing process and when they're in 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 which create fewer harmful gas emissions.

The Baxi 800 825 has an ERP Heat rating of "A".

What is the warranty period for the Baxi 800 825?

Parts and labour charges incurred for repairs made to your new Baxi 800 825 are covered by a 10 year warranty.

Baxi 800 825 heat only Gas boiler frequently asked questions

Baxi 800 825 - a regular, combi or system boiler?

If you are considering installing a heat only boiler in your house or flat, then the Baxi 800 825 boiler is certainly worth investigating.

You can program a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) to provide hot water and heating at particular times of the day. Heat only boilers consist of a cold water tank (often housed out of sight in the loft), a hot water cylinder with an immersion heater (normally situated in an airing or landing cupboard), and a control panel.

Regular boilers are best suited for large households with many members, at least two of whom often need hot water at the same time.

Should I install a Baxi 800 825 heat only boiler in my home?

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 800 825 heat only's output is 25 kW, so which types of property would this Baxi 800 825 heat only boiler be appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Baxi 800 825 heat only would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.


Making space for the Baxi 800 825

The Baxi 800 825 measures TBC mm high and TBC mm wide by a depth of TBC mm.

Is the Baxi 800 825 non-condensing or condensing?

The Baxi 800 825 boiler is a condensing gas boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' gas bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn gas to generate the power they need to operate.

How energy efficient is the Baxi 800 825 heat only boiler?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

If you would like your next boiler to help in the fight against climate change, would the Baxi 800 825 heat only be a suitable choice?

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 800 825 was awarded an efficiency rating of 93% with a SEDBUK grading of "A".

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 800 825 has a rating of "A".

How many years' warranty does the Baxi 800 825 heat only come with?

Parts and labour charges incurred during a repair on the Baxi Baxi 800 825 boiler are covered by a 10 year warranty.
