Are you considering installing a new boiler for the first time or updating the old one?

Do you need help picking the right one for your home? The information we share below can help you make an informed choice.

The first step to picking the best boiler for your home is knowing, which is the best type. We have listed a few options, highlighting their pros, cons, and suitability.

1. Combi Boilers

Combi or combination boilers are popular in the United Kingdom. They are designed to provide hot water and heat to homes, eliminating the need to install water reservoirs. You can opt for an electric or gas combi-boiler Installed by a boiler and central heating specialist.

• Unlimited, readily available hot water and heat
• No need to install a secondary tank
• The boiler takes up less space

• Reduced water pressure when drawing hot water from several taps at a time
• The installation process is complicated

Suitable For:
Combination boilers are ideal for most homes. However, they are best suited where the family does not rely heavily on hot water, drawing a lot at the same time.

2. System Boilers

System boilers or sealed system boilers have a water cylinder located in an airing space; thus, eliminating the need to install a water tank.

• No need to install a water tank in the loft
• Hot water available via several taps at the same time

• Instant hot water not readily available
• Hot water can run out, and reheating takes time
• The cylinder needs a secure place for installation

Suitable For:
System boilers are an excellent choice if you need hot water running from several taps simultaneously.

3. Conventional Boilers

Conventional boilers or Open vent boilers, also known as regular boilers, have a water tank and cylinder system.

• Hot water available via several taps at the same time

• Hot water can be depleted, and reheating takes time
• You need a designated space for the water tank and cylinder

Suitable For:
Conventional boilers are ideal for homes that need hot water running from different taps at the same time.

4. Condensing Boilers

Condensing boilers are more of an attribute to your boiler instead of a type of boiler. For instance, it can be a condensing-conventional boiler or condensing combination boiler. Nonetheless, condensing boilers have a high energy efficiency rating. They trap and re-use some of the heat that escapes a non-condensing boiler’s flue. That is how they can generate more heat using the same amount of fuel other boiler types use, therein saving you money. Given such energy efficiency, it is no wonder all current boilers are condensing boilers.

Energy-Efficient Boilers

The latest boilers are designed to be energy-efficient and sold with a label stating their energy rating, similar to what is on most kitchen appliances. They adhere to the regulations that govern Energy Related Products made with an Eco-Design.

Can I Save Money On Heating Via Other Means?

Investing in energy-efficient boils is the ideal starting point when trying to save on heating. However, it all will be pointless if the heat escapes from your home. That is why you also should ensure that your house has proper insulation and is draught-proofed. The two are energy-efficiency upgrades worth making as you invest in better heating systems. The upgrades need not be time-consuming or expensive.


Installing insulation in your home is somewhat an invasive measure compared to draught-proofing. The approach used when draught-proofing is to identify draught spots around your house. They can be characterized by cracks on the doors and windows or gaps between the doors and windows and the supporting frame.

Filling the cracks and gaps is not that complicated. You can use self-adhesive foam strips to plug the holes and cracks. Conversely, you can place brushes or letterboxes at the space at the bottom of the doors to prevent indoor heat from escaping. Putty or sealant will be the best remedy if the cracks around the door and window frames are too big to fix using the self-adhesive foam strips.

On the other hand, specialist products will be necessary when dealing with significant gaps like a chimney flue. In such a situation, you can use a chimney balloon to block the flue and preventing air from escaping.


Many people will attest to how insulation is efficient. Nevertheless, it is more expensive and complicated to install but results in higher savings compared to draught-proofing.

Roughly 25% of heat loss in the average home is through the roofing. Hence, loft insulation is one of the measures worth taking if you have an attic. Many modern homes and those built in the last decade are likely to have insulation; the older buildings might not. Moreover, the older properties that might have insulation installed may not have sufficient energy-efficiency levels.

You can get loft insulation in home deports and DIY stores or hire a professional to install the insulation.

Insulating the walls can have more money-saving results, but you should leave the job to a professional. The insulation to use depends on the type of home you have and your location.

For instance, houses built after 1930 are likely to have cavity walls (having an inner and outer barrier). You can use cavity wall insulation to fill the space. The process entails drilling holes on the outer wall and then pumping the insulation into the gap.

Solid walls are most popular with homes built earlier. Insulating the solid walls involves packing the insulation on the walls’ outer and inner surfaces, which can be costly. However, it is something worth considering if you want to save money on energy in the long-term.

Unfortunately, every year there are multiple people who die and get seriously injured due to accidents caused by gas leaks. As a result, gas safety is essential in every home. We will now look at some of the causes of gas leaks, how to find out if you have one and what to do about it.


The Causes Of Gas Leaks

In many cases, gas leaks are caused by improperly working appliances such as cookers, boilers etc. It can also occur due to poorly fitted appliances where the gas escapes. This usually happens from the gas hose and from the seal. So, to prevent this from happening, you should get your appliances properly fixed by a Gas Safe engineer that is fully accredited.

In the event that you’re unsure of the engineer’s accreditation, all you need to do is ask the engineer for their registration card or look at the Gas Safe website. Once you have older appliances, it is important that you regularly service them and always hire a Gas Safe engineer to do so.

If you have second hand or significantly older appliances, you should be very careful if you’re moving into a new house or apartment. Thankfully, there are many signs that indicate that your appliance has a leak or is faulty and we will take a look at them below.

How to determine if you have a gas leak?

Smelling gas in your home is the easiest sign that shows that there is a gas leak. On the other hand, if there is a carbon monoxide leak then you won’t be able to smell it but you’ll feel certain physical effects. Carbon monoxide will make you feel nauseous, lightheaded and even a bit dizzy and sick. So, once you start to feel these ways, you should leave the enclosed area as soon as possible and get fresh air outside. Once you stop feeling these ways, then your home likely has a carbon monoxide leak.

When it comes to your appliances, there are many signs that show that there is a leak, even if you can’t smell anything off in you home. These signs include:
– A low orange and yellow flame as oppose to a blue, sharp flame
– Issues with the pilot light blowing out easily
– Burnt or scorched parts on your appliance’s exterior
– Musty smells as well as a lot of condensation on surrounding windows

How to stop gas leaks from occurring?

It is best to focus on preventing gas leaks from happening as oppose to waiting for a gas leak to occur before fixing the issue. The first place you should pay attention to are the appliances in your home.
Always make sure that you hire a Gas Safe engineer to install all of your appliances as well as check them and maintain them regularly.

Once your appliance needs to be maintained, you should ensure that only a registered Gas Safe engineer does so. In order to prevent poisoning from carbon monoxide leaks, you should have a carbon monoxide alarm installed within your house. These alarms are quite inexpensive and they can be easily purchased from most hardware and DIY stores. They look and work in a similar fashion to smoke alarms. It is best to install these alarms in an open area such as a room or hallway and ensure that you swap out the batteries regularly.

What is the best course of action to take if I smell gas?

Once you smell gas, you should immediately spring into action. The very first thing you should do is take off your gas supply. This is located at your gas meter and the valve there is used to change gas flow. It may be a bit challenging to find this valve, so it is best to become familiar with it before you run into any issues.

Next, you should try to open your doors and windows so that fresh air can enter your home and reduce the concentration of gas within your home. Make sure that you leave the doors and windows open as long as you need to so that the gas can easily flow out of your home.

In the event that it isn’t possible for you to open any windows, it is best that you go outside and breathe in clean fresh air. Once you are aerating your home, make sure that you don’t smoke, use matches or even use electrical switches such as doorbells, light switches and more. This is because the spark could easily cause an explosion. Even lighting a candle can cause an explosion to happen due to the high concentration of leaked gas.

After you’ve completed these steps, the next thing you should do is get professional help. You can call National Gas at 0800 111 999. Make sure that you add this phone number to your phone so that you can quickly and easily call when necessary. You can call this number free of charge and you should also place the number on the fridge or any other easily accessible region in your home. You can also call National Gas anytime as they are available 24/7.

Avoid calling inside of your home if you suspect there is a gas leak. Instead, you should leave your home and call on your mobile or ask a friend or neighbor to call. Also, once the emergency engineer arrives, ensure that there is someone available to give them access to your property as well as help them to find the leak. In the event that there is a fire, you should opt to call the Fire Service (999) first before national Gas.
