What Constitutes An ‘Emergency’?

Any boiler issue is obviously important to get remedied as soon as possible, but in a triage system of urgency, some issues take precedence.

You can consider any of the following an emergency boiler matter:

  • Suspected gas leak (natural gas or carbon monoxide)

  • No heating or hot water during winter (especially important if you have children in the home)

  • Water is streaming out of a boiler or pipe at a very quick rate

Possible Symptoms of Carbon Monoxide Poisoning:

  • Headaches

  • Dizziness

  • Nausea and vomiting

  • Tiredness and confusion

  • Stomach pain

  • Shortness of breath

  • Confusion

  • Irregular heartbeat

  • Seizures

Unfortunately, small gas leaks often do not have a smell or other physical signs, which means they can go undetected for a long time.

However, after a while you may notice signs such as a sulphur or rotten egg smell, hissing from a gas line, a damaged gas pipe or dead houseplants.

Or if you notice the small flame as seen through the viewing window on older boilers is yellow instead of blue, this could be a gas leak indicator.

Undetected gas leaks also pose the potentially lethal risk of gas ignition explosions, this is when a leaking gas source combines with the air and an ignition source (e.g lighter flame) to cause an explosive and violent combustion.

What To Do If You Think you Have A Gas Leak

If you suspect your property has a gas leak it is crucial to carry out these steps:

  1. Ensure all people and pets are evacuated from the house.

  2. Leave doors and windows open.

  3. Turn off the gas at the mains tap- this can usually be found near the gas meter.

  4. Immediately call the National Gas Emergency Service number on 0800 111 999 as soon as you have evacuated the house.

  5. Do not turn any power or light switches on or off.

  6. Do not light any sort of flame within the property.

  7. Do not use any appliances that could cause a spark.

Boiler Replacement Costs

Even in the event of a boiler issue not deemed an ‘emergency’, you can still contact an engineer for a call out if you believe it’s required, however the 24 hour rate will be down to that engineer or firm’s labour and expertise pricing but you can expect this will be around 30% above normal day rates.

Things To Note About Boiler Replacements

Regular boiler companies will first have to send an engineer for an on site assessment, potentially allowing the situation to further deteriorate as time elapses, also it may prove prudent to contact and compare price quotes for any emergency boiler replacements.

Remember to fully document and authenticate prices before committing to any work being carried out to avoid disputes about the service costs down the line.

Consider A Combi Boiler

What Is A Combi Boiler And What Are Their Benefits?

Combi (combination) boilers link a home’s central heating system and water heating into a single unit, with all components integrated within the boiler. 

The combi signals a sensor upon hot water demand, then takes water directly from the mains and the heat exchanger heats it for distribution to water outlets. This means there's no accompanying cylinder or hot water tank.

This allows a compact boiler which could fit into a standard kitchen cupboard or be wall mounted, to thoroughly heat a home without stealing lots of space. Combi systems are also easier to service or for boiler replacement due to their popularity, meaning greater availability.

Another great benefit of a combi boiler is its efficiency. By heating water on demand as opposed to constantly heating stored water, you can save energy and cut costs on your fuel bills. A new combi boiler should be around 90% efficient, so replacing your old boiler could save you up to £445 according to The Energy Saving Trust.

iHeat New Boiler Costs

Boilers can be a daunting purchase for many people as they’re an appliance with a lot of responsibility, providing heat for you and your family is something you want to get right. Boilers aren’t exactly a quickly disposable item either, potentially lasting you a decade.

Here at iHeat, we want to remove all of this undue stress and make the decision making process of upgrading to a new central heating system, as easy as possible.

Boiler costs can vary depending on a number of factors including their brand, model, fuel, output, warranty, labour and installation type. Typically a new boiler will cost between £1,845 and £3,500, below is a list of average boiler installations offered by iHeat (guide only).
