Baxi 800 825 heat only Gas boiler frequently asked questions

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

Looking for a gas heat only boiler for your house or flat? If you are, the Baxi 800 825 boiler may be worth considering.

Heat only boilers (often referred to as conventional boilers, standard boilers or regular boilers) consist of a large cold water tank, hot water cylinder with an immersion heater, and a control panel. The cold water tank is often situated in a loft or attic while the hot water cylinder tends to be located in an airing or landing cupboard.

The major advantage of a heat only boiler compared to the more contemporary combi boiler is that it’s possible to run more than one appliance requiring hot water at the same time. With a combi boiler, switching two hot water taps on at the same time will lead to a drop in water pressure, temperature and volume to both points.

Best suited for larger homes, you can program hot water and central heating for times and days that suit you and your family. However, if you forget to set the timer and your hot water cylinder is empty, then you may have to wait up to an hour before you run a bath.

Is the Baxi 800 825 heat only boiler suitable for my house or apartment?

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

A PlumbProud boiler engineer would almost certainly recommend that this Baxi 800 825 heat only boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is a Baxi 800 825 boiler?

The Baxi 800 825 measures TBC mm in height and has a width of TBC mm and a depth of TBC mm.

Is the Baxi 800 825 non-condensing or condensing?

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

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

What energy efficiency ratings have been awarded to the Baxi 800 825 heat only?

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 installing the Baxi 800 825 heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

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 800 825 are 93% with a SEDBUK rating of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

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

If the Baxi 800 825 breaks down, will I be covered by the warranty?

The Baxi 800 825 boiler comes with a parts and labour warranty lasting 10 years.

Baxi 800 825 heat only Gas boiler frequently asked questions

Is this Baxi 800 825 boiler a combi, system or regular boiler?

If you want a heat only boiler for your flat or house, the Baxi 800 825 might be an option for you to consider.

You may hear a heat only boiler described as a standard boiler, a regular boiler, or a conventional boiler but the terms mean the same. Heat only boilers require a hot water cylinder (usually stored in a landing or airing cupboard) and a cold water storage tank (usually stored in the loft) to operate. Your water is kept warm by the hot water cylinder throughout the day.

A heat only boiler lets you schedule the hot water and central heating you want for set times of the day. However, you'll have to wait before having a bath or shower if you forget to set it and there's no hot water left in the tank.

If you have a bigger family or more than one bathroom, a heat only boiler is a better option than a combi boiler in many cases. This is because a combi boiler struggles to maintain water volume, pressure and temperature to multiple points in a home simultaneously.

Is the Baxi 800 825 heat only boiler a suitable option 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".

A PlumbProud boiler engineer would almost certainly recommend that this Baxi 800 825 heat only boiler is most suitable 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 is TBC mm high by TBC mm wide by TBC mm deep.

Is this Baxi boiler condensing or non-condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Baxi 800 825.

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.

Is the Baxi 800 825 heat only a good choice for the environment?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

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 the Baxi 800 825 heat only be an environmentally-friendly choice? If so, let's look at its performance figures.

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) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

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

Am I covered if my Baxi 800 825 heat only boiler breaks down?

A parts and labour warranty of 10 years is included with the Baxi Baxi 800 825 boiler.
