Top 5 Ravenheat Boiler Problems

  1. Boiler isn’t firing up

    If your boiler is failing to start then there are several possible causes including a broken thermocouple, a draught blowing the pilot light out or a deposit built up in the pilot light. There will be instructions in your boiler’s manual that can talk you through reigniting but before attempting this it’s very important to to check that there aren’t any issues with the gas supply.

    Never carry out any work on your own gas boiler, so if it doesn’t reignite get in touch with a Gas Safe registered engineer.

  2. Flashing red light

    A flashing red light suggests that there is an electrical fault with your boiler, potentially caused by the gas valve, PCB or flame sensor. It may be the case that they need replacing, get in touch with a Gas Safe registered engineer in this instance.

  3. Without heating and hot water

    You should start by checking the boiler pressure and your thermostat as they could be causing the issue. If not, the potential causes can be low levels of water, broken diaphragms and airlocks or motorised valves failing.

    With Ravenheat boilers specifically, this issue could be down to a faulty pump, if you think that your boiler needs a new part then you’ll need to get a Gas Safe registered engineer on the case. They’ll be able to thoroughly diagnose the problem and replace any broken parts where necessary.

  4. Radiators not heating up

    If the radiators in your home aren’t coming on when they should be, or are only heating up at the bottom, then they probably need to be bled. This is something that you can do yourself, our guide to bleeding radiators can talk you through the process, but you can contact an engineer if you’d prefer.

  5. Low boiler pressure

    If the boiler pressure has dropped below 1, then you might have an issue. Get to know more with our guide to low boiler pressure.

Who Should You Choose to Replace a Ravenheat Boiler?

After you’ve decided that you’d like a brand new boiler in your home, you have to start thinking about who you’d like do the installation. Your two options are a local engineer or a national company, both of which offer many benefits depending on your preferences.

Local engineers can offer some very competitive rates and if you like to receive service with a personal touch then you’re likely to be in direct communication with one person throughout.

With national companies, on the other hand you will have big brand protection which is a great bonus and they’ll be able to provide ongoing boiler cover.

When receiving quotes, we don’t recommend going with the first one you receive, instead aim to get up to 3. This way, you’re more likely to find the best deal for you.

Boiler Insurance and Ongoing Cover

It can be easy to think that your boiler warranty expiring is the end of the road in terms of cover for your boiler, but that doesn’t have to be the case. Boiler insurance is something well worth considering. If you think boiler insurance is the way to go then keep an eye out for any that offer an annual service and safety inspection. And remember, you’re under no obligation whatsoever to take this insurance out with your energy supplier.
