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

What type of boiler is Worcester Bosch’s Greenstar CDi FS Regular 42 - system, regular or combi?

The Worcester Bosch Greenstar CDi FS Regular 42 is a heat only boiler you may wish to consider if you want this type of boiler for your house or flat.

Heat only boilers, sometimes known as standard boilers, regular boilers or conventional boilers, are better for homes with multiple bathrooms or larger families where members of your household may need to use hot water at the same time as each other, such as a shower in the bathroom and a hot water tap in the kitchen. This is because, unlike combi boilers, they can handle demand from more than one point at a time with no drop in water pressure, temperature and volume.

Heat only boilers use a hot water cylinder with an immersion heater (normally installed in an airing or landing cupboard) and a cold-water tank (normally stored in the loft).

You program a heat only boiler to provide you with the central heating and hot water you need at specific times of the day, such as first thing in the morning. However, if you forget to set timings and there is no water left in the hot water tank, you may have to wait up to an hour before you have hot water again.

Is a Worcester Bosch Greenstar CDi FS Regular 42 heat only a suitable choice for my house or flat?

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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler has an output of 42 kW, so which types of property would it be most appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that the most suitable type of property for this Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler would be larger properties including detached homes containing 15 or more radiators and two or more bathrooms.


What size is the Worcester Bosch Greenstar CDi FS Regular 42 boiler?

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

Many properties in the UK still feature a floor-standing boiler like the Worcester Bosch Greenstar CDi FS Regular 42. This is despite the fact that more compact wall-mounted types have been the first choice of homeowners over the last 20 years seeking more space to live for their families. If you want, you can choose to replace your floor-standing model with a wall-mounted, more compact boiler. However, this could involve having to change the pipework, adding to overall installation costs.

You would benefit from savings on your gas each year that would eventually pay off your investment in a wall-mounted boiler.

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

The Worcester Bosch Greenstar CDi FS Regular 42 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.

Is the Worcester Bosch Greenstar CDi FS Regular 42 heat only an energy-efficient boiler?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

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

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Worcester Bosch Greenstar CDi FS Regular 42 was awarded an efficiency rating of 92% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Worcester Bosch Greenstar CDi FS Regular 42 is "A".

Is this Worcester Bosch Greenstar CDi FS Regular 42 heat only covered by a warranty?

You receive a parts and labour warranty of 7 years with the Worcester Bosch Greenstar CDi FS Regular 42 boiler.

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

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

Worcester Bosch’s Greenstar CDi FS Regular 42 is one you might consider if you’re looking for a heat only boiler for your house or flat.

If your home has more than one bathroom or you have a large family which uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Is the Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler a suitable choice for my property?

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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler has an output of 42 kW, so which types of property would it be most appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


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

The Worcester Bosch Greenstar CDi FS Regular 42 is 850 mm in height, 400 mm in width and 600 mm in depth.

Many homeowners dislike the floor-standing boilers (like the Worcester Bosch Greenstar CDi FS Regular 42) they have in their properties because they feel that they are bulky and take up too much room. If this is you and you want to replace what you have now with a compact, wall-mounted boiler, we can do this for you, although please note that you may need to pay for new piping.

The gas bill savings offered by modern boilers are significant, however, and you should be able to recoup your investment in a few years.

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

Condensing gas boilers like the Worcester Bosch Greenstar CDi FS Regular 42 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

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

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

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Will choosing a Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler for your home be positive for the environment? Let's examine the figures.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Worcester Bosch Greenstar CDi FS Regular 42 was given an efficiency rating of 92% and a SEDBUK grading of "A".

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 warranty does the Worcester Bosch Greenstar CDi FS Regular 42 heat only boiler come with?

The Worcester Bosch Greenstar CDi FS Regular 42 boiler is provided with a parts and labour warranty lasting 7 years.
