Is the Biasi Advance Plus 7 25 boiler a standard, combi or system model?

Looking for a gas system boiler for your flat or house? Then the Biasi Advance Plus 7 25 may be an option you should consider.

A system boiler needs a hot water cylinder to work but it does not require a cold water tank, unlike with heat only boilers. This makes system boilers suitable for properties that lack loft space (or have no loft at all) or where a loft conversion is planned. The cylinder stores hot water for use throughout the day and water can be distributed to more than one tap or shower simultaneously without a loss of pressure or temperature (something combi boilers really struggle with).

System boilers are generally found in larger homes or properties housing large families. System boilers are easier to install than heat only boilers because their major components, including the circulation pump, are built-in and, of course, no cold water tank is needed.

With a system boiler, you use the control panel to set times for when you want the heating and hot water to be available but, unlike combi boilers, they cannot deliver hot water instantly. If you don't set your timer, you will have to wait for the water to heat up.

Is the Biasi Advance Plus 7 25 system boiler from the Advance Plus 7 range a suitable choice for my house or flat?

Whether this Biasi Advance Plus 7 25 System 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 Plus 7 25 system outputs at a maximum of 25 kW, so which types of property would this Biasi Advance Plus 7 25 System boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that the Biasi Advance Plus 7 25 system boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Is the Biasi Advance Plus 7 25 a condensing or non-condensing boiler?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Biasi Advance Plus 7 25.

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.

What energy efficiency ratings have been awarded to the Biasi Advance Plus 7 25 system?

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

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

Would choosing a Biasi Advance Plus 7 25 system help the environment? Let’s see what the performance figures suggest.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Biasi Advance Plus 7 25 was given an efficiency rating of 92% and a SEDBUK grading of "A".

How long is the warranty period on the Biasi Advance Plus 7 25 system boiler?
