Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only Oil boiler frequently asked questions

Is this Worcester Bosch Greenstar Danesmoor Utility 18/25 boiler a combi, system or regular boiler?

The Worcester Bosch Greenstar Danesmoor Utility 18/25 boiler is an option you may wish to consider if you're looking for a heat only boiler for your house or flat.

Large family homes and properties with more than one bathroom benefit most from installing a heat only boiler (also referred to as a conventional boiler, a standard boiler or a regular boiler). Heat only boilers require both a cold water tank and hot water cylinder and an immersion heater. The immersion heater heats and keeps the water warm and feeds hot water to taps, radiators and other sources via the boiler.

Tell your boiler the times and days when you want hot water and central heating and it'll be there waiting for you. However, if you forget and there's no hot water left in your tank, you'll have to wait up to an hour before it's ready.

The biggest benefit of a heat only boiler is that, unlike a combi boiler, it’s possible to run two taps with hot water at the same time with no drop in pressure, volume or temperature (a known issue with combi boilers). It also means you can shower and have the dishwasher running at the same time without your water pressure being affected.

Is a Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only boiler appropriate for my house or apartment?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the oil your boiler needs to work.

The Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only outputs at a maximum of 25 kW, so which types of property would this Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only boiler be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that the level of output from this Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only boiler would make it a suitable installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Worcester Bosch Greenstar Danesmoor Utility 18/25 size

The size of the Worcester Bosch Greenstar Danesmoor Utility 18/25 boiler is 855 mm high, 370 mm wide, and 600 mm deep.

Compact wall-hung boilers have been the most popular boiler installation choice over the past two decades. If you have a floor-standing boiler in your home like the Worcester Bosch Greenstar Danesmoor Utility 18/25 and you want to replace it with a wall-mounted unit so that you and your family have more space to live, this is possible - however, please note that there may be an additional premium on fitting costs if your current pipework needs replacing.

The savings you make on your oil bills over the coming years will cover the cost of installation completely.

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

The Worcester Bosch Greenstar Danesmoor Utility 18/25 is a condensing oil 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 oil 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 oil bills.

Is the Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only good for the environment?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Let's take a closer look at whether installing a Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only would be a good choice for the environment.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Worcester Bosch Greenstar Danesmoor Utility 18/25 are 90% with a SEDBUK rating of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Worcester Bosch Greenstar Danesmoor Utility 18/25 has been given an ERP rating of "A".

What length of warranty does the Worcester Bosch Greenstar Danesmoor Utility 18/25 come with?

The parts and labour warranty on the Worcester Bosch Greenstar Danesmoor Utility 18/25 lasts for 2 years.

Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only Oil boiler frequently asked questions

Is the Worcester Bosch Greenstar Danesmoor Utility 18/25 boiler a combi, system or regular boiler?

If you’re looking for a heat only boiler for your house or flat, you may wish to the consider the Worcester Bosch Greenstar Danesmoor Utility 18/25.

Heat only boilers (often referred to as conventional boilers, standard boilers or regular boilers) consist of a large cold water tank, hot water cylinder with an immersion heater, and a control panel.
