Worcester Bosch Greenstar CDi FS Regular 42 heat only Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar CDi FS Regular 42 a regular, combi or system boiler?

Suitable for a house or a flat, the Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler is worth considering if you want a heat only boiler.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

Is a Worcester Bosch Greenstar CDi FS Regular 42 heat only the right boiler for my house or flat?

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 Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler has an output rate of 42 kW, so which types of property would this be suitable for?

A heating engineer would recommend that this Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more bathrooms.


What are the proportions of a Worcester Bosch Greenstar CDi FS Regular 42 boiler?

The Worcester Bosch Greenstar CDi FS Regular 42 is 850 mm tall, 400 mm wide, and 600 mm deep.

Despite the increase in demand for compact, wall-mounted boilers over the last 20 years, hundreds of thousands of homes still have large floor-standing boilers like the Worcester Bosch Greenstar CDi FS Regular 42. If you would like a wall-mounted boiler to replace your existing floor-standing unit to free up space, we can carry out this installation for you but please bear in mind that we may also need to replace your existing pipework, which will add extra costs to the work.

You should however be able to repay your investment in full within a few years with the savings you make on your gas bills.

Is the Worcester Bosch Greenstar CDi FS Regular 42 a condensing or non-condensing boiler?

The Worcester Bosch Greenstar CDi FS Regular 42 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Worcester Bosch Greenstar CDi FS Regular 42 heat only considered environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would choosing a Worcester Bosch Greenstar CDi FS Regular 42 heat only help the environment? Let’s see what the performance figures suggest.

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 Worcester Bosch Greenstar CDi FS Regular 42 was given an efficiency rating of 92% 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.

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Worcester Bosch Greenstar CDi FS Regular 42 has an ERP rating of "A".

What is the warranty period on a Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler?

The Worcester Bosch Greenstar CDi FS Regular 42 boiler is covered by a parts and labour warranty of 7 years.

Whether this Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

It is possible to replace your floor-standing unit with a wall-hung and more compact boiler but please note that much of the pipework could need replacing, making the overall cost of installation higher.

Your new compact will save you money on your gas bills every quarter, however, and those savings should cover the costs within a few years.

Worcester Bosch Greenstar CDi FS Regular 42 – condensing or non-condensing?

The Worcester Bosch Greenstar CDi FS Regular 42 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.

How environmentally friendly is the Worcester Bosch Greenstar CDi FS Regular 42 heat only?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

Do the available figures suggest that installing the Worcester Bosch Greenstar CDi FS Regular 42 heat only in your property would be an environmentally friendly choice?

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 Worcester Bosch Greenstar CDi FS Regular 42 is rated as 92% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Worcester Bosch Greenstar CDi FS Regular 42.

How long am I covered by the warranty for if the Worcester Bosch Greenstar CDi FS Regular 42 breaks down?
