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

Worcester Bosch’s Greenstar Ri 15Ri is one you might consider if you’re looking for a heat only boiler for your house or flat.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

Is a Worcester Bosch Greenstar Ri 15Ri heat only boiler suitable for my house or flat?

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 gas than is necessary.

The Worcester Bosch Greenstar Ri 15Ri heat only boiler has an output level of 15 kW, so which types of property would it be appropriate for?

An experienced PlumbProud heating engineer would recommend that the level of output from this Worcester Bosch Greenstar Ri 15Ri heat only boiler would make it a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

Is this Worcester Bosch boiler non-condensing or condensing?

The Worcester Bosch Greenstar Ri 15Ri is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.
