Biasi Advance Plus 7 30 - a combi boiler, system boiler or regular boiler?

The Biasi Advance Plus 7 30 boiler is an option you may wish to consider if you're looking for a combi 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 a Biasi Advance Plus 7 30 combi boiler suitable 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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Biasi Advance Plus 7 30 combi boiler has an output rate of 30 kW, so which types of property would this be suitable for?

A heating engineer would recommend that this Biasi Advance Plus 7 30 Combi boiler would be a suitable installation choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler like the Biasi Advance Plus 7 30, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Biasi Advance Plus 7 30 Combi boiler's flow rate is TBCl/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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.

Advance Plus 7 30 – non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Biasi Advance Plus 7 30.

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.

How energy efficient is the Biasi Advance Plus 7 30 combi boiler?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Would choosing the Biasi Advance Plus 7 30 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Biasi Advance Plus 7 30 was given an efficiency rating of 92% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

How long is the warranty period on the Biasi Advance Plus 7 30 combi boiler?

The parts and labour warranty offered with this Biasi Advance Plus 7 30 Combi boiler covers you for 7 years.
