1️⃣ Decide on the right type of boiler
The size of your property, the number of people living in it, and the demand for heating and hot water will determine which boiler type is right for your home.🏠
Combi boilers are the most modern and popular type of boiler in the UK. A combi is a single cost-effective heating system that doesn’t need to be installed alongside any additional tanks or cylinders. Great news if your property has limited space available. They deliver instant heating and hot water on demand as and when needed without the need for any tanks or cylinders. As a result, they’re perfectly suited to homes with 1-2 bathrooms (depending on the output rating).
While combi boilers have several benefits, some considerations need to be made too. As combi boilers take water directly from the mains, you will need a high water pressure at your property. Otherwise, the hot water that comes out of the tap will always be weak. Also, they’re unable to deliver a strong supply of hot water to more than a single tap at a time (in most cases) which is why they’re best suited to smaller properties.
A system boiler is a great option for homes with 2 or more bathrooms and high demand for hot water. This is because, rather than heating water on demand, they store it in a hot water cylinder. If your property has a high demand for hot water then it’s well worth the additional space.
While storing hot water in a cylinder does allow a system boiler to meet higher demands for hot water, there will be times when you need to wait for it to fill back up. This may, on occasion, postpone your bath for a little while – a problem you won’t face with combi boilers.
2️⃣ Research the best boiler brands.
Once you’ve decided on the right type of boiler for your home then you’ll need to select a model from one of the many UK leading boiler manufacturers.🧐 The best boiler manufacturers in terms of homeowner reviews and installer feedback are widely considered to be:
⭐️ Worcester Bosch
Each of these brands manufactures mainly gas-fueled boilers with an extensive warranty. Not sure which boiler type is best suited to your home? Then you should seek the expert advice of our
3️⃣ Choose the right size of boiler:
Getting the boiler size right is vital. And by boiler size, we mean its power, which is measured in kilowatts (kW).⚡️
A suitable output for the boiler installed in your property will be determined by the size of your property and the number of people living in it. Getting the output rating right is essential. Otherwise, if it’s too low it will struggle to meet demand and if it’s too high then your heating bills could shoot up unnecessarily.🏠
For an average three or four-bedroom house that typically has around ten radiators a small or medium boiler (for example 24-30 kW) should be sufficient. A larger house with substantially more radiators or an en-suite bathroom will generally need a larger one, typically 30-35 kW.
The above is very much a rule of thumb, you should always have your home’s hot water demand assessed by one of our iSafe surveyors before going ahead with a boiler replacement.
4️⃣ Choose a place for your boiler:
Modern boiler installations can be incredibly flexible. Giving you the freedom to choose where you’d like your boiler to be installed. Having it installed in a kitchen or utility room is by no means a requirement. 🤷♂️
Most boilers manufactured nowadays are designed to be as compact as possible. So they won’t take up too much space and many can be hidden away in a wall-mounted cupboard. One necessity of gas boiler installations is that they must be installed onto an external wall.
This is so that waste gases can be easily emitted out and away from the property through the flue pipe.🏠
Note that moving a boiler from one location to another will add to the costs of a boiler replacement.
5️⃣ Know your budget:
A question we get asked almost every day…🤷♂️ “How much for a new boiler?” For many people, the choice is often dictated by budget.
- The price of buying a new boiler will depend on several things, including:
- Manufacturer, range, and model.
- Boiler type (combi, system, or regular).
- Output rating (this determines how powerful the boiler will be and is measured in kW).
- On top of the cost of the boiler itself, you’ll also need to think about the installation. Boiler installation prices can also vary greatly, thanks to factors such as:
- Time of year.
- Difficulty of the installation.
- Whether the boiler is being moved to a new location.
- Whether it’s a like-for-like boiler replacement (replacing a combi with a combi, for example).
With so many variables that can have an impact on the total cost of buying a new boiler, booking a free boiler survey with iSafe Gas will help you to explore the available options.👍
6️⃣ Check the warranty:
A boiler warranty will give you the peace of mind that you’re covered in the unlikely event of an issue.
All UK boiler manufacturers offer warranties on their boilers. However, the terms and length of the warranty will both vary depending on the manufacturer and model. Boiler warranties typically vary from 1-10 years with some now going beyond 10 years. ATAG boilers come with an impressive 14-year warranty – the longest of any boiler available in the UK!
The warranty of some boilers can be extended when installed by a heating engineer certified by the manufacturer.
It’s worth asking our iSafe Surveyors who quote on your job about the warranties we can offer.
7️⃣ Check your installer’s qualifications & reviews:
The heating engineer you hire to install your new boiler must be fully-qualified. 📝 This means hiring a Gas Safe registered engineer for gas boiler installations. Oil boilers must be installed by an OFTEC technician.👨🏭
To make sure the installer is suitably qualified, you can check online. This means visiting the Gas Safe register and looking up the company that you’re considering. In addition to this, always ask to see their ID card as soon as they arrive at your property.
You can be rest assured that iSafe Gas has fully qualified, vetted, time-served Gas Safe registered engineers along with a full log of 5-star customer reviews. ⭐️⭐️⭐️⭐️⭐️
