Johnson and Starley QuanTec 28 HR Combi Gas boiler frequently asked questions

What type of boiler is Johnson And Starley’s QuanTec 28 HR - system, regular or combi?

You might want to consider the Johnson And Starley QuanTec 28 HR 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.

Is a Johnson And Starley QuanTec 28 HR combi boiler appropriate for my house or apartment?

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

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Johnson And Starley QuanTec 28 HR combi boiler is 28 kW kilowatts. Which types of property would this be 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.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Johnson and Starley QuanTec 28 HR Combi boiler's flow rate is 12 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

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.


How big is the Johnson And Starley QuanTec 28 HR?

The Johnson And Starley QuanTec 28 HR boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Is the Johnson And Starley QuanTec 28 HR condensing or non-condensing?

We recommend that, if possible, you choose a condensing boiler like the Johnson And Starley QuanTec 28 HR.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your gas bills, particularly if you're replacing a boiler more than 15 years old.

Is the Johnson And Starley QuanTec 28 HR combi an environmentally friendly boiler?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

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.

Is the Johnson And Starley QuanTec 28 HR combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

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 Johnson And Starley QuanTec 28 HR was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Johnson And Starley QuanTec 28 HR is "A" for heat and "A" for hot water.

How long is the warranty period on a Johnson And Starley QuanTec 28 HR combi boiler?

The Johnson And Starley QuanTec 28 HR boiler is covered by a parts and labour warranty of 8 years.

Johnson and Starley QuanTec 28 HR Combi Gas boiler frequently asked questions

Which category of boiler does the Johnson And Starley QuanTec 28 HR fit into?

The Johnson And Starley QuanTec 28 HR is worthy of consideration if you're looking for a combi boiler for your flat or house.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Is the Johnson And Starley QuanTec 28 HR combi boiler suitable for my house or apartment?

Whether this Johnson and Starley QuanTec 28 HR 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 28 HR combi is 28 kW, so which types of property is this Johnson and Starley QuanTec 28 HR Combi boiler appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Johnson and Starley QuanTec 28 HR Combi boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Johnson and Starley QuanTec 28 HR Combi boiler's flow rate is 12 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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.


How large is a Johnson And Starley QuanTec 28 HR boiler?

The Johnson And Starley QuanTec 28 HR measures TBC mm tall, TBC mm wide, and TBC mm deep.

Johnson And Starley QuanTec 28 HR – condensing or non-condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Johnson And Starley QuanTec 28 HR for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the combi Johnson And Starley QuanTec 28 HR boiler energy efficient?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Would installing a Johnson And Starley QuanTec 28 HR combi boiler in your home be a green choice? Let's look at the numbers.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Johnson And Starley QuanTec 28 HR was given an efficiency rating of 94% and a SEDBUK grading of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Johnson And Starley QuanTec 28 HR is "A" for heat and "A" for hot water.

Will I be covered if the Johnson And Starley QuanTec 28 HR combi breaks down?

On the Johnson And Starley QuanTec 28 HR, the manufacturer offers a parts and labour warranty of 8 years.
