Johnson and Starley QuanTec 30 Combi Gas boiler frequently asked questions

Is the Johnson And Starley QuanTec 30 a combi boiler, system boiler or regular boiler?

You may wish to consider installing the Johnson And Starley QuanTec 30 if you are looking for a combi boiler for your house or flat.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is a Johnson And Starley QuanTec 30 combi the right boiler for my house or flat?

Whether this Johnson and Starley QuanTec 30 Combi boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Johnson And Starley QuanTec 30 combi is 23 kW, so which types of property would this model be appropriate for?

An experienced boiler engineer would recommend that this Johnson and Starley QuanTec 30 Combi boiler would be a suitable installation choice 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 30 in your home, you should consider flow rates as well as output rates. This Johnson and Starley QuanTec 30 Combi boiler's flow rate is 12 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.


What are the dimensions of the Johnson And Starley QuanTec 30 boiler?

The Johnson And Starley QuanTec 30 occupies a space of TBC mm high by TBC mm wide and TBC mm deep.

Johnson And Starley QuanTec 30 – non-condensing or condensing?

The Johnson And Starley QuanTec 30 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Johnson And Starley QuanTec 30 combi boiler rated as environmentally friendly?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Do the available figures suggest that installing the Johnson And Starley QuanTec 30 combi in your property would be an environmentally friendly choice?

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Johnson And Starley QuanTec 30 was awarded an efficiency rating of "93%", equivalent to a "B" rating on the SEDBUK system.

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Johnson And Starley QuanTec 30, the ERP rating is "A" for heat and "A" for hot water production.

What warranty does the Johnson And Starley QuanTec 30 combi boiler come with?

The Johnson And Starley QuanTec 30 boiler is covered by a parts and labour warranty of 8 years.

Johnson and Starley QuanTec 30 Combi Gas boiler frequently asked questions

What type of boiler is the Johnson And Starley QuanTec 30 - regular, system or combi?

You might want to consider the Johnson And Starley QuanTec 30 for your house or flat if you are looking for a combi boiler.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

Would the Johnson And Starley QuanTec 30 combi be a suitable choice of boiler for my house or flat?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Johnson And Starley QuanTec 30 combi outputs at a maximum of 23 kW, so which types of property would this Johnson and Starley QuanTec 30 Combi boiler be appropriate for?

Most heating engineers would suggest that the Johnson And Starley QuanTec 30 combi boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and 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 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. This Johnson and Starley QuanTec 30 Combi boiler's flow rate is 12 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.


What are the dimensions of the Johnson And Starley QuanTec 30 boiler?

The Johnson And Starley QuanTec 30 measures TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Johnson And Starley QuanTec 30 a non-condensing or condensing boiler?

The Johnson And Starley QuanTec 30 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Johnson And Starley QuanTec 30 combi rated as environmentally friendly?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

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.

If you would like your next boiler to help in the fight against climate change, would the Johnson And Starley QuanTec 30 combi be a suitable choice?

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Johnson And Starley QuanTec 30 was given a 93% energy efficiency rating and a SEDBUK grading of "B".

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 30 are "A" for heat and "A" for hot water.

Is there a warranty on the Johnson And Starley QuanTec 30 combi boiler if it breaks down?

The parts and labour warranty on the Johnson And Starley QuanTec 30 covers all repair-related costs for 8 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
