Your RADIANT RBC 24 (ENERGY series) is a gas- fired wall hung high efficiency boiler, which generates heat for heating and or hot water production. RBC 24 (ENERGY series) boiler can be operated together with a domestic hot water cylinder, which stores a larger volume of hot water. This boiler is fitted with internal hot water production and a domestic hot water cylinder to achieve increased hot water convenience.
Hot water production
When you open a hot water tap sink, shower, bath, etc, the boiler operates automatically and supplies hot water at a temperature set by you. The boiler automatically stops producing hot water. when you close the hot water tap.
Common Issues
The RADIANT RBC 24 (ENERGY series) could be constantly switching itself off for a number of reasons. Some of the key culprits are:
- Low boiler pressure
- Lack of water flow due to a closed valve or the pump not circulating the water around the system properly
- A build up of sludge or other debris within the system
- Too much air within the system
- Thermostat issues
Boiler is leaking
A leak coming from your boiler is never a good sign. And the cause of the leak will depend where the water is coming from. Before attempting to locate the cause of the leak, stop the water supply and turn off the central heating. If the leak is coming from the pressure valve it could be the case that the boiler pressure is too high. It's important to note that you should never attempt to repair a boiler leak yourself, always call out a Gas Safe registered engineer. A leak from the pump seal is a sign that it may have worn out and need replacing. The most common cause of a leaking boiler is a broken internal component, such as a pump seal or pressure valve.
no heat or hot water
Before jumping to conclusions about potential faults, check that power is being supplied to the boiler. If your boiler is receiving power then we can begin looking further into possible issues. If you find that it isn't able to do either then you'll want to get it fixed as quickly as possible. There's no single issue that can lead to your boiler failing to provide heat or hot water. You should be able to rely on your boiler to provide your home with heating and hot water.
Your RBC 24 (ENERGY series) boiler should display an error code to help you locate the source of the problem. However, to give you some ideas, possible issues include: Low boiler pressure so ensure the boiler pressure is set according to the manufacturers instructions ( usually between 1 and 2 on the pressure gauge The condensate pipe has frozen and needs thawing out we'll come onto this later in the article Fuel isn't making its way into your property. If you have a gas boiler, ensure that your gas supplier is still supplying fuel. Double check the thermostat settings and set the desired temperature higher than the current room temperature Older boilers will have a pilot light ( a small flame that constantly burns before lighting a larger flame when heating or hot water is needed. if the pilot light goes out then the boiler won't be able to fire into action.
Hot water but no heating
RADIANT RBC 24 (ENERGY series) boiler should provide your home with domestic hot water and central heating. If you've found that you're getting hot water from the taps but no central heating, there's a problem. Increasing the boiler pressure is something you can do without calling out a heating engineer. However, if you're the slightest bit unsure, don't hesitate to contact a professional. When you have no central heating, first make sure your thermostat is working then check to see if the boiler pressure is too low. Boiler pressure is a term used to describe the pressure of the hot water running through the central heating system. Should the boiler pressure drop too low, the central heating will fail to work. Low boiler and thermostat troubles pressure aren't the only reasons why you might have domestic hot water but no heating. Unfortunately though, this is where it gets a little more complex... Thermostats allow you to control the temperature of the central heating, as well as the time it should come on. If the heating hasn't come on at the expected time, double check the settings. If the boiler pressure is high enough and your thermostat is fine, there could be a fault in need of professional repair. Common causes of hot water but no heating include broken diaphragms and airlocks or a failure of the motorised valves. For heating systems that include a combi boiler, there could be an issue with the diverter valve. RBC 24 (ENERGY series) boiler provide hot water on demand and heating and the diverter valve directs the hot water to either the radiators or the hot water outlets. In the event that it gets stuck, you could end up with hot water but no heating, or vice versa. A Gas Safe registered engineer will be able to diagnose faulty diaphragms and airlocks, motorised valves or diverter valves and carry out the necessary repairs or replace broken parts
Blink boiler falling
In the case that the boiler is leaking around the pipes or tank then that's a strong indication of corrosion. Otherwise, it could be the result of a poor installation. Either way, we recommend calling out an engineer who will be able to diagnose and fix the leak.
RBC 24 (ENERGY series) boiler is not responding to the thermostat
Pairing your boiler with a thermostat particularly a smart thermostat is a great way to increase the efficiency of your home. However, if your boiler isn't responding to the thermostat then it can be particularly frustrating. Start by making sure the temperature on the thermostat is above the current room temperature. If the boiler still doesn't respond after turning the room thermostat right up then it's time to look into the problem a little further:
- Check it has a full charge and working batteries
- Look through the temperature settings and daily schedules that may be preventing the heating from coming on
- Smart thermostats need to be connected to the internet so make sure your Wi- Fi is running
If you find that it isn't able to do either then you'll want to get it fixed as quickly as possible. You should be able to rely on your boiler to provide your home with heating and hot water.
