Biasi Advance Plus 25 Combi Gas boiler frequently asked questions

Biasi Advance Plus 25 - a regular boiler, combi boiler or system boiler?

If you are searching for a combi boiler for your house or flat, the Biasi Advance Plus 25 is certainly one to consider.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Is the Biasi Advance Plus 25 combi boiler suitable for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Biasi Advance Plus 25 combi boiler has an output of 25 kW, so which types of property would it be most appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Biasi Advance Plus 25 combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

In addition to output rates, you need to consider a combi boiler's flow rate when making your choice.

The flow rate of your boiler dictates the maximum volume of water (measured in litres per minute) that it can heat and distribute to your taps, showers and radiators at any one time.

However, a combi boiler like the Biasi Advance Plus 25 can only heat and deliver water at the rate at which it actually enters your property. For this reason, you should also find out what the mains pressure to your house is before purchasing a boiler.

It's pointless spending more money on a boiler with a 17l/m flow rate if the local water pressure is 11l/m. To give you an indication of average water demand, a power shower typically requires 12 litres of water per minute and a basin tap 4-8 litres. This Biasi Advance Plus 25 Combi boiler's flow rate is 13 L/m.

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 is the size of the Biasi Advance Plus 25?

The Biasi Advance Plus 25 is TBC mm [H] by TBC mm [W] by TBC mm [D] in size.

Is the Biasi Advance Plus 25 a condensing or non-condensing boiler?

The Biasi Advance Plus 25 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Biasi Advance Plus 25 combi considered environmentally friendly?

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

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Do the available figures suggest that installing the Biasi Advance Plus 25 combi in your property would be an environmentally friendly choice?

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 Biasi Advance Plus 25 was awarded an efficiency rating of 88.7% with a SEDBUK band rating of "B".

The aim of the Energy Related Products (ERP) Directive is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Biasi Advance Plus 25 is "A" for heat and "A" for water.

What is the warranty period for the Biasi Advance Plus 25?

The Biasi Advance Plus 25 is supplied with a parts and labour warranty of 5 years.

Biasi Advance Plus 25 Combi Gas boiler frequently asked questions

Biasi Advance Plus 25 - a combi boiler, system boiler or regular boiler?

If you are searching for a combi boiler for your house or flat, the Biasi Advance Plus 25 is certainly one to consider.

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 the Biasi Advance Plus 25 combi boiler the right choice for my house or apartment?

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 Biasi Advance Plus 25 combi's output is 25 kW, so which types of property would this Biasi Advance Plus 25 Combi boiler be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Biasi Advance Plus 25 Combi boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Biasi Advance Plus 25 Combi boiler's flow rate is 13 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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 big is the Biasi Advance Plus 25?

The Biasi Advance Plus 25 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Biasi Advance Plus 25 – condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Biasi Advance Plus 25 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Biasi Advance Plus 25 combi boiler environmentally friendly?

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.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

If you would like your next boiler to help in the fight against climate change, would the Biasi Advance Plus 25 combi be a suitable choice?

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 Plus 25 was rated at 88.7% with a SEDBUK grading of "B".

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Biasi Advance Plus 25, the ERP rating is "A" for heat and "A" for hot water production.

What warranty does the Biasi Advance Plus 25 combi boiler come with?

The Biasi Advance Plus 25 is covered by a parts and labour warranty of 5 years following installation.
