Who are Warmhaus

Warmhaus have been manufacturing Combi boilers since they were established in 1996. They were started as a subsidiary of Beyçelik Holding who are involved in many fields such as automotive, energy, tourism and insurance. You can find out even more about Warmhaus and their range of boiler on Boiler Guide.

Top 5 Warmhaus Boiler Problems

  1. Low pressure

    Without constant pressure, your boiler won’t be performing to its full potential. If you find that your boiler has low pressure then there’s probably either a water leak or a bleeding radiator. If there’s not a leak, or the leak has been repaired you can go about re-pressurising the boiler. You can use our steps to re-pressurising your system to find out how to do this but if you’re not confident then contact an engineer.

  2. High pressure

    Boiler pressure normally sits somewhere between 1 and 2 bars on the pressure gauge, if it’s above this then your boiler pressure is too high. This can be caused when a boiler has recently been re-pressurised as the valve or filling loop may still be open, ensure the valve is closed. You can also reduce the pressure by bleeding your radiators.

  3. Without heating and hot water

    The first thing to do in this case is check that there’s not an issue with boiler pressure or your thermostat. If you can rule both of these out then there are several possible causes such as broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels.

  4. Strange noises

    If you’re hearing unfamiliar banging or gurgling noises then one of the most common causes is air in the system. If this isn’t the case then either the water pressure is too low or it’s kettling. We’ve put together a guide to central heating noises which should help you uncover the cause of the noises from boiler.

  5. Radiators not heating up

    Finding that your radiator is hot towards the bottom and cold at the top, there could be too much air, sludge build-up or heat not being distributed equally. You should try bleeding your radiators but if this doesn’t work, or you don’t feel confident doing that, then contact an engineer.

Which Boiler Issues Need an Engineer?

We’ve put together the list below to help you find potential causes of some of the more common boiler problems.

Problem Possible Cause Do you need an engineer?
No heating or hot water Possibly caused by several things such as broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels Yes
Dripping and leaking Most likely to be a broken internal component but it will depend where the water is leaking from Yes
Banging, whistling or gurgling noises Air in the system could be causing this, otherwise it could be that the water pressure is too low Yes
Pilot light goes out The thermocouple could be broken which is in turn stopping the gas supply Yes
Losing Pressure Could be a water leak in the system, the pressure relief valve needs replacing or due to recently bleeding radiators If there’s a leak
Frozen condensate pipe You should see this displayed on your boiler as an error code or warning notification Yes
Thermostat issues Your thermostat could be turned off or isn’t set to the correct settings (time etc.) Consider replacing
Kettling Limescale or sludge building up on the heat exchanger Yes
Radiators not getting hot Sludge or air building up in the system or an unequal distribution of heat Your radiators will need to be bled which doesn’t require an engineer but if you don’t feel like carrying out the task yourself
Boiler keeps switching itself off Could be low water pressure, a problem with the thermostat or a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly Yes

Who Should You Choose to Replace a Warmhaus Boiler?

Coming to the decision that you’d like to replace your boiler means finding someone to replace your old one.

The simple part is knowing that the engineer carrying out the work must be Gas Safe registered. Ultimately though, the replacement will be carried out by a national company or a local engineer, which one is right for you?

In a lot of cases, local engineers offer extremely competitive rates for personal service where you’ll be able to talk with the same person throughout.

National companies however, might tempt you as they can offer additional services such as ongoing boiler cover and you’ll have big brand protection.

When deciding who to carry out the replacement, we don’t recommend that you go with the first engineer you come across. It’s worth getting up to 3 quotes from different engineers to find the best deal for you and your home.

Boiler Insurance and Ongoing Cover

When a boiler warranty comes to an end you might want to think about boiler insurance. If you take a look at boiler insurance, make a note of the ones offering annual services and safety inspections. Boiler insurance can be taken out with your energy supplier but there’s no obligation to do so.

Warmhaus Boiler Warranty

All of the Combi boilers that Warmhaus have available come with a 2 year warranty. We’ve put together a complete guide to Warmhaus warranties so that you know exactly what to expect. One thing you’ll need to do to keep the warranty valid is arrange an annual Warmhaus boiler service throughout the duration of the warranty period. This will also help your boiler to last longer and run to its most efficient, keeping your energy bills as low as possible.
