The size of boiler you need will depend on the size of your home, how many radiators and bathrooms you have and how many people live there. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you. Other boiler types such as system boilers or conventional boilers may be better suited to larger homes because they have bigger outputs.
When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!
Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:
• Switch off your boiler and let it cool completely
• Make sure both ends of your filling loop are attached
• Open both valves to allow cold water into the system – you’ll hear it start to move
• Look out for your pressure gauge to show 1.5 bar
• Close both valves
• Switch your boiler back on
• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!
If you’re thinking about getting a new gas boiler for your home or property, then you might also be wondering how much it’ll cost you so you can set a budget and start planning. As simple as this question sounds, it’s actually very tricky to provide a simple and short answer as the costs of installing a new gas boiler alone varies greatly based on the parts needed, the amount of work required, your location, their availability as well as the company you hire for the project.
When it comes to purchasing a new gas boiler the price you’re expected to pay also depends on multiple influencing factors such as the type, brand as well as your most preferred gas boiler model. However, one thing you should have in mind is the fact that your gas boiler is right at the heart of your home or property and can be a complicated piece of machinery. As a result, you wouldn’t expect gas boilers to come cheap. Generally, it’s going to cost within the range of £500 to about £2,500 to get a new gas boiler. Therefore, it’s always advisable to obtain all necessary details and facts before you decide to purchase a replacement gas boiler.
This price range may seem too high as it’s usually a turn off for most homeowners. However, it’s worth noting that gas boiler replacement costs and gas boiler installation costs are, more often than not, compensated by the saving you’ll make off your utility bills - all thanks to the new and more energy efficient boiler you just installed in your home. And even more importantly, when it has been estimated that roughly half of the amount spent on energy on an annual basis depends on your boiler.
