Johnson and Starley QuanTec 24 Combi Gas boiler frequently asked questions

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

If you are considering installing a combi boiler in your house or flat, then the Johnson And Starley QuanTec 24 boiler is certainly worth investigating.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Would the Johnson And Starley QuanTec 24 combi be a suitable boiler for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Johnson And Starley QuanTec 24 combi's output at 16 kW, which types of property would this Johnson and Starley QuanTec 24 Combi boiler be most appropriate for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Johnson And Starley QuanTec 24 combi would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Johnson And Starley QuanTec 24 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. This Johnson and Starley QuanTec 24 Combi boiler's flow rate is 10 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

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 Johnson And Starley QuanTec 24

The Johnson And Starley QuanTec 24 boiler measures TBC mm [H] x TBC mm [W] x TBC mm [D] in size.

Johnson And Starley QuanTec 24 – condensing or non-condensing?

The Johnson And Starley QuanTec 24 is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

Is the Johnson And Starley QuanTec 24 combi considered environmentally friendly?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

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 Johnson And Starley QuanTec 24 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Johnson And Starley QuanTec 24 has been given a rating of 93% for energy efficiency, equivalent to a SEDBUK "A" rating.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Johnson And Starley QuanTec 24 are "A" for heat and "A" for hot water.

How long is the warranty period on the Johnson And Starley QuanTec 24 combi boiler?

The Johnson And Starley QuanTec 24 boiler offers a parts and labour warranty of 8 years.

Johnson and Starley QuanTec 24 Combi Gas boiler frequently asked questions

What kind of boiler is the Johnson And Starley QuanTec 24 - standard, combi or system?

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

Traditional boilers require at least one large cylindrical tank to work, normally housed in a large landing cupboard, utility room or the attic. As the UK has some of the world's smallest residential properties, manufacturers introduced the combi boiler in the 1970s to address the issue of space while meeting homeowners' need for central heating and hot water at the same time.

Combi boilers don't need external storage tanks. Instead, they draw water directly from the mains, heat it and then distribute it on demand to the areas where it is needed.

The most important disadvantage of combi boilers is that they have a maximum capacity for the amount of water they can heat up. This means that, if one person in your household is having a shower and another person turns on a hot water tap elsewhere, then the volume, pressure and temperature of the water to both points decreases.

Is a Johnson And Starley QuanTec 24 combi the right boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Johnson And Starley QuanTec 24 combi's output at 16 kW, which types of property would this Johnson and Starley QuanTec 24 Combi boiler be most appropriate for?

A heating engineer would recommend that the Johnson And Starley QuanTec 24 combi boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

If you are thinking about installing a combi boiler like the Johnson And Starley QuanTec 24 in your home, you should consider flow rates as well as output rates. This Johnson and Starley QuanTec 24 Combi boiler's flow rate is 10 L/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water 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.


Making space for the Johnson And Starley QuanTec 24

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

Is this Johnson And Starley boiler non-condensing or condensing?

This Johnson And Starley QuanTec 24 is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

How does the Johnson And Starley QuanTec 24 combi rate environmentally?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

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.

Is the Johnson And Starley QuanTec 24 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Johnson And Starley QuanTec 24 is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Johnson And Starley QuanTec 24 are "A" for heat and "A" for hot water.

Will I be covered if the Johnson And Starley QuanTec 24 combi breaks down?

The manufacturer offers a parts and labour warranty of 8 years on the Johnson And Starley QuanTec 24 boiler to new customers.
