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?

The Johnson And Starley QuanTec 28 HR boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

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.

Should I install a Johnson And Starley QuanTec 28 HR combi boiler in 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 28 HR combi's output at 28 kW, which types of property would this Johnson and Starley QuanTec 28 HR Combi boiler be most appropriate for?

Most experienced Gas Safe boiler installers would suggest that the Johnson And Starley QuanTec 28 HR combi boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Johnson and Starley QuanTec 28 HR Combi boiler's flow rate is 12 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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 28 HR

The measurements of the Johnson And Starley QuanTec 28 HR are TBC mm by TBC mm by TBC mm.

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?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would choosing the Johnson And Starley QuanTec 28 HR 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 Johnson And Starley QuanTec 28 HR was given an efficiency rating of 94% 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.

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.

Does the Johnson And Starley QuanTec 28 HR combi boiler come with a warranty?

The parts and labour warranty on the Johnson And Starley QuanTec 28 HR covers all repair-related costs for 8 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

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

Is the Johnson And Starley QuanTec 28 HR a system boiler, a combi boiler or a regular boiler?

Suitable for a house or a flat, the Johnson And Starley QuanTec 28 HR combi boiler is worth considering if you want a combi boiler.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

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

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Johnson And Starley QuanTec 28 HR combi is 28 kW, so which types of property would this Johnson and Starley QuanTec 28 HR Combi boiler be appropriate for?

An experienced PlumbProud boiler engineer would recommend that this Johnson and Starley QuanTec 28 HR Combi boiler be installed in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With combi boilers like the Johnson And Starley QuanTec 28 HR, 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 28 HR Combi boiler is 12 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 is the size of 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 non-condensing or condensing?

The Johnson And Starley QuanTec 28 HR is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Does the Johnson And Starley QuanTec 28 HR combi protect the environment?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

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.
