What type of boiler is the Worcester Bosch Greenstar Ri 18Ri - regular, system or combi?

The Worcester Bosch Greenstar Ri 18Ri boiler could be suitable for your house or flat if you are looking for a new heat only boiler.

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. The cold water tank is often situated in a loft or attic while the hot water cylinder tends to be located in an airing or landing cupboard.

The major advantage of a heat only boiler compared to the more contemporary combi boiler is that it’s possible to run more than one appliance requiring hot water at the same time. With a combi boiler, switching two hot water taps on at the same time will lead to a drop in water pressure, temperature and volume to both points.

Best suited for larger homes, you can program hot water and central heating for times and days that suit you and your family. However, if you forget to set the timer and your hot water cylinder is empty, then you may have to wait up to an hour before you run a bath.

Is a Worcester Bosch Greenstar Ri 18Ri heat only boiler right for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Worcester Bosch Greenstar Ri 18Ri heat only is 18 kW kilowatts, so which types of property would this be most suitable for?

A PlumbProud heating engineer would recommend that this Worcester Bosch Greenstar Ri 18Ri heat only boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

Would choosing the Worcester Bosch Greenstar Ri 18Ri heat only boiler be an environmentally friendly decision? Here's what the figures say.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Worcester Bosch Greenstar Ri 18Ri has been given a rating of 92% for energy efficiency, equivalent to a SEDBUK "A" rating.
