Johnson and Starley QuanTec 24 Combi Gas boiler frequently asked questions

Johnson And Starley QuanTec 24 - a regular boiler, combi boiler or system boiler?

The Johnson And Starley QuanTec 24 boiler could be suitable for your house or flat if you are looking for a new combi boiler.

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 a Johnson And Starley QuanTec 24 combi boiler appropriate for my house or apartment?

Whether this Johnson and Starley QuanTec 24 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 Johnson And Starley QuanTec 24 combi is 16 kW, so which types of property is this Johnson and Starley QuanTec 24 Combi boiler appropriate for?

An experienced PlumbProud Gas Safe engineer would almost certainly recommend that this Johnson and Starley QuanTec 24 Combi boiler would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Johnson And Starley QuanTec 24, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Johnson and Starley QuanTec 24 Combi boiler is 10 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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 are the proportions of a Johnson And Starley QuanTec 24 boiler?

The Johnson And Starley QuanTec 24 measures TBC mm in height by TBC mm in width by TBC mm in depth.

Is the Johnson And Starley QuanTec 24 condensing or non-condensing?

Condensing boilers like the Johnson And Starley QuanTec 24 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the combi Johnson And Starley QuanTec 24 boiler energy efficient?

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.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

If you would like your next boiler to help in the fight against climate change, would the Johnson And Starley QuanTec 24 combi be a suitable choice?

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 Johnson And Starley QuanTec 24 was given an efficiency rating of 93% and a SEDBUK grading of "A".

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Johnson And Starley QuanTec 24 scores "A" for heat and "A" for water.

Does the Johnson And Starley QuanTec 24 combi boiler come with a warranty?

The Johnson And Starley QuanTec 24 boiler has a warranty covering parts and labour costs for up to 8 years after installation.

Johnson and Starley QuanTec 24 Combi Gas boiler frequently asked questions

Is the Johnson And Starley QuanTec 24 a system boiler, a combi boiler or a regular boiler?

When looking for a combi boiler for your house or flat, the Johnson And Starley QuanTec 24 might be a suitable option for you.

Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.

With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.

The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.

Is the Johnson And Starley QuanTec 24 combi boiler suitable 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.

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 Johnson And Starley QuanTec 24 combi boiler has an output rate of 16 kW, so which types of property would this be suitable for?

Most Gas Safe boiler installers would recommend that this Johnson and Starley QuanTec 24 Combi boiler would be suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

You'll also need to be sure to choose a combi boiler with the right flow rate for your home.

The flow rate indicates the maximum volume of hot water (measured in litres per minute) that your boiler can distribute at any given time. This means that if you and your family are likely to be using several taps and showers simultaneously or you have a lot of radiators, you need a boiler with a high flow rate. This Johnson and Starley QuanTec 24 Combi boiler's flow rate is 10 L/m.

As with all combi boilers, the Johnson And Starley QuanTec 24 is only able to heat and distribute water at the rate at which it actually enters your property.

For this reason, you shouldn't purchase a boiler with a very high flow rate if the flow rate in your mains pipes is lower because the extra capacity doesn't mean it can draw more water from the mains pipes.

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 size is the Johnson And Starley QuanTec 24 boiler?

The size of the Johnson And Starley QuanTec 24 boiler is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Johnson And Starley QuanTec 24 condensing or non-condensing?

The Johnson And Starley QuanTec 24 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 Johnson And Starley QuanTec 24 combi boiler environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Do the figures suggest that installing the Johnson And Starley QuanTec 24 combi at your property would help in the fight against climate change?

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Johnson And Starley QuanTec 24 was awarded an efficiency rating of 93% with a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use through to final disposal, with the aim of reducing harmful gas emissions.

The Johnson And Starley QuanTec 24 is rated "A" for heat and "A" for water.

How many years' warranty does the Johnson And Starley QuanTec 24 combi come with?

Parts and labour charges incurred during a repair on the Johnson And Starley Johnson And Starley QuanTec 24 boiler are covered by a 8 year warranty.
