Worcester Bosch Greenstar 4000 15kW System Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar 4000 15kW - regular, system or combi?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Worcester Bosch Greenstar 4000 15kW.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Is a Worcester Bosch Greenstar 4000 15kW system boiler suitable for my apartment or house?

Whether this Worcester Bosch Greenstar 4000 15kW System 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 Worcester Bosch Greenstar 4000 15kW system is 15 kW, so which types of property is this Worcester Bosch Greenstar 4000 15kW System boiler appropriate for?

An experienced Gas Safe engineer would be likely to recommend that this Worcester Bosch Greenstar 4000 15kW System boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.

Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Worcester Bosch Greenstar 4000 15kW has an efficiency rating of 94% with a SEDBUK grade of "A".

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.

Worcester Bosch Greenstar 4000 15kW System Gas boiler frequently asked questions

Worcester Bosch Greenstar 4000 15kW - a combi boiler, system boiler or regular boiler?

You may wish to consider installing the Worcester Bosch Greenstar 4000 15kW if you are looking for a system boiler for your house or flat.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

Is the Worcester Bosch Greenstar 4000 15kW system boiler the right choice for my house or apartment?

Selecting the right boiler for your home means choosing a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Worcester Bosch Greenstar 4000 15kW system has an output of 15 kW, so which types of property would this Worcester Bosch Greenstar 4000 15kW System boiler be appropriate for?

A PlumbProud heating engineer would recommend that this Worcester Bosch Greenstar 4000 15kW System boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.
