Biasi Advance 25 Combi Gas boiler frequently asked questions

Is the Biasi Advance 25 a combi boiler, system boiler or regular boiler?

The Biasi Advance 25 is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Is a Biasi Advance 25 combi boiler suitable for my house or flat?

Whether this Biasi Advance 25 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The Biasi Advance 25 combi outputs at a maximum of 25 kW, so which types of property would this Biasi Advance 25 Combi boiler be appropriate for?

To most experienced Gas Safe engineers, the Biasi Advance 25 combi Advance would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

In addition to the output rate, you should consider a boiler's "flow rate" (measured in litres per minute) when choosing a combi boiler.

If you have a lot of radiators and bathrooms in your home and members of your household want to use hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate. This Biasi Advance 25 Combi boiler's flow rate is 12 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. Homes with higher than average demand for hot water, and particularly those in low mains pressure areas, may find that a combi boiler is not the right answer for them.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead to better serve you and your family.


How big is the Biasi Advance 25?

The Biasi Advance 25 measures TBC mm in height and has a width of TBC mm and a depth of TBC mm.

Biasi Advance 25 – condensing or non-condensing?

The Biasi Advance 25 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.

How does the Biasi Advance 25 combi rate environmentally?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would installing a Biasi Advance 25 combi boiler in your home help combat climate change? What do the figures suggest?

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Biasi Advance 25 was rated at 88.7% with a SEDBUK grading of "A".

Is there a warranty on the Biasi Advance 25 combi boiler if it breaks down?

The parts and labour warranty on the Biasi Advance 25 lasts for 5 years.

Biasi Advance 25 Combi Gas boiler frequently asked questions

Is the Biasi Advance 25 a combi, system or regular boiler?

The Biasi Advance 25 is worthy of consideration if you're looking for a combi boiler for your flat or house.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Is the Biasi Advance 25 combi boiler from the Advance range a suitable choice 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.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

The output of the Biasi Advance 25 combi is 25 kW, so which types of property would this Biasi Advance 25 Combi boiler be an appropriate choice for?

A Gas Safe engineer would recommend that the Biasi Advance 25 combi boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

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 Biasi Advance 25 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.


Biasi Advance 25 size

The dimensions of the Biasi Advance 25 are TBC mm tall, TBC mm wide, and TBC mm deep.

Advance 25 – condensing or non-condensing?

We recommend that you select a condensing boiler like the Biasi Advance gas Biasi Advance 25 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Biasi Advance 25 combi environmentally friendly?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing a Biasi Advance 25 combi boiler in your home help combat climate change? What do the figures suggest?

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Biasi Advance 25 was awarded an efficiency rating of 88.7%, equivalent to a SEDBUK grade of "A".

How many years does the warranty period cover on a Biasi Advance 25 boiler?

The Biasi Advance 25 boiler comes with a 5 year warranty for parts and labour.
