Worcester Bosch Greenstar Danesmoor External 12/18 - a regular, combi or system boiler?

If you are searching for a heat only boiler for your house or flat, the Worcester Bosch Greenstar Danesmoor External 12/18 is certainly one to consider.

Also known as standard boilers, regular boilers or conventional boilers, heat only boilers feature both a hot water/immersion cylinder (normally found in a utility room or landing cupboard) and a cold water tank (normally found in an attic).

Heat only boilers enable you to program in times when you want heating and hot water to be available. If you forget to set the times and there's no water left in the hot water cylinder, you may have to wait up to an hour to run a bath or shower.

If your home has more than one bathroom or you have a large family, a heat only boiler would be a good choice because it can service demand for hot water from multiple points at the same time. This is in contrast to a combi boiler which can only heat a limited volume of water at any one time meaning that, when two or more points want hot water, the water delivered is cooler and lower in both volume and pressure.

Is the Worcester Bosch Greenstar Danesmoor External 12/18 heat only boiler suitable for my house or apartment?

Whether this Worcester Bosch Greenstar Danesmoor External 12/18 heat only 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 oil bills than you need to for years to come.

The output of the Worcester Bosch Greenstar Danesmoor External 12/18 heat only is 18 kW, so which types of property is this Worcester Bosch Greenstar Danesmoor External 12/18 heat only boiler appropriate for?

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.
