Is the Biasi Advance Plus 7 30 boiler a standard, combi or system model?

The Biasi Advance Plus 7 30 is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

Is the Biasi Advance Plus 7 30 combi boiler from the Advance Plus 7 range a suitable choice for my house or flat?

Whether this Biasi Advance Plus 7 30 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Biasi Advance Plus 7 30 combi is 30 kW, so which types of property is this Biasi Advance Plus 7 30 Combi boiler appropriate for?

Most experienced Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This Biasi Advance Plus 7 30 Combi boiler's flow rate is TBCl/m.

Like all combi boilers, the Biasi Advance Plus 7 30 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

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.

The size of the Biasi Advance Plus 7 30

The Biasi Advance Plus 7 30 measures TBC mm in height and has a width of TBC mm and a depth of TBC mm.

Biasi Advance Plus 7 30 – condensing or non-condensing?

Condensing gas boilers like the Biasi Advance Plus 7 30 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

How environmentally friendly is the Biasi Advance Plus 7 30 combi?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will choosing to install a Biasi Advance Plus 7 30 combi in your home help the environment? Let's review the figures.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Biasi Advance Plus 7 30 was awarded an efficiency rating of 92% with a SEDBUK band rating of "A".

How long am I covered by the warranty for if the Biasi Advance Plus 7 30 breaks down?

Biasi offers a parts and labour warranty of 7 years on the Biasi Advance Plus 7 30.
