Worcester Bosch Greenstar Danesmoor External System 18/25 System Oil boiler frequently asked questions

Worcester Bosch Greenstar Danesmoor External System 18/25 - a combi boiler, system boiler or regular boiler?

When looking for a system boiler for your house or flat, the Worcester Bosch Greenstar Danesmoor External System 18/25 might be a suitable option for you.

System boilers need a hot water cylinder to work - normally fitted inside an airing or landing cupboard or similar spot. Unlike heat only boilers, they do not require a separate cold water tank, making them a more suitable choice if you have no loft, lack space in the attic, or are planning to do a loft conversion.

These boilers distribute hot water around your home to your taps and radiators using (often built-in) circulating pumps and they're easier to install as there is one less component (the water tank) to find room for. A system boiler needs to be programmed to tell it what times you want heat and hot water - unlike combi boilers, they don't provide hot water on demand.

Is the Worcester Bosch Greenstar Danesmoor External System 18/25 system boiler suitable for my house or apartment?

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

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for oil than is necessary.

The Worcester Bosch Greenstar Danesmoor External System 18/25 system boiler has an output level of 25 kW, so which types of property would it be appropriate for?

To most boiler engineers, the Worcester Bosch Greenstar Danesmoor External System 18/25 system Greenstar Danesmoor External System would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What dimensions does a Worcester Bosch Greenstar Danesmoor External System 18/25 have?

The Worcester Bosch Greenstar Danesmoor External System 18/25 is 950 mm in height, 565 mm in width and 780 mm in depth.

The Worcester Bosch Greenstar Danesmoor External System 18/25 is an external floor-standing system boiler intended for placement outside the home. In addition to providing you with more indoor space and reducing noise, this makes it easier for a service technician to access it if something goes wrong. The chance of carbon monoxide leaking into your home is also greatly reduced.

Floor-standing external boilers are housed in a weatherproof covering allowing them to be placed outside your home with only a minimal risk of rusting. Using external boilers is also safer because there will be less chance of oil leaks in your home which can cause significant internal damage and leave you with an oily odour that is hard to remove.

Is the Worcester Bosch Greenstar Danesmoor External System 18/25 a non-condensing or condensing boiler?

We recommend the Worcester Bosch Greenstar Danesmoor External System 18/25 as it is a modern condensing oil boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more oil.

Condensing boilers significantly reduce your quarterly oil costs and they're better for the environment.

Worcester Bosch Greenstar Danesmoor External System 18/25 System Oil boiler frequently asked questions

Is the Worcester Bosch Greenstar Danesmoor External System 18/25 boiler a standard, combi or system model?

If you are considering installing a system boiler in your house or flat, then the Worcester Bosch Greenstar Danesmoor External System 18/25 boiler is certainly worth investigating.

System boilers need a hot water cylinder to work, which is normally situated in an airing cupboard or similar. However, unlike heat only boilers, system boilers don’t require a separate cold water tank, meaning they are a preferred option for some homeowners, especially those planning a loft conversion in the future.

They use (often built-in) circulating pumps to distribute hot water to your taps and radiators and installation is often easier from scratch with heat only boilers as there’s one less component (the water tank) to purchase and fit.

System boilers also need programming for heat and hot water and don’t offer this instantly. However, the cylinder can keep water hot for use afterwards so you shouldn’t have to wait around for your bath water so long as you set your timer and have it on long enough to heat the water you’ll need for the day.

Is the Worcester Bosch Greenstar Danesmoor External System 18/25 system boiler a suitable choice for my property?

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

This Worcester Bosch Greenstar Danesmoor External System 18/25 System boiler gets its power from oil and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher oil bills.

The Worcester Bosch Greenstar Danesmoor External System 18/25 system boiler has an output level of 25 kW, so which types of property would it be appropriate for?

To most boiler engineers, the Worcester Bosch Greenstar Danesmoor External System 18/25 system Greenstar Danesmoor External System would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

By selecting a modern condensing boiler, you'll save money on your oil bills as well as benefitting the wider environment.

Is the Worcester Bosch Greenstar Danesmoor External System 18/25 system good for the environment?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.
