What is a combi boiler?

Combi boiler is short for combination boiler which has two important jobs. The first is to give you instant and constant hot water by heating the cold water as it flows through your boiler, sending hot water to your bath and sink taps. The second job your combi boiler has is to send hot water around your central heating system, to heat up your radiators. As the hot water heating and central heating parts are combined together inside your boiler, we call this type of boiler, a combination boiler or combi boiler.


What are boiler controls?

When you have a new boiler installed you will usually need a few new controls too. Typically we supply things like room thermostats, especially SMART thermostats which let you control room temperatures on your phone. Other controls include programmers (sometimes combined within your thermostat), hot water cylinder thermostats, 2-port and 3-port valves and motorised valves. During hot weather you won’t need your radiators on but will still want to use your hot water. Motorised valves move the heat between radiators and hot water so you can choose to have hot water only on warmer days.


What is condensate?

When your boiler burns gas, condensation forms inside. During cold days this can be particularly noticeable as it flows out of your boiler with all gases and looks a bit like steam in the air. Condensate also gathers within your boiler and is then drained away usually via a white plastic condensate pipe. Condensate is completely safe so no need to worry.


What is a condensate pipe?

A condensate pipe isn’t allowed to be metal, making it easy to spot as the only plastic pipe coming out of your boiler - it is usually white plastic. Your condensate pipe is used to run waste water out of your boiler and towards a suitable drain. A condensate pipe is an important part of any modern boiler and can’t run without it.


What does ErP mean?

ErP is short for the Energy-related Products directive, a piece of legislation from 2015 that instructs how the energy efficiency information of products are labelled. From September 2015 all new domestic and light commercial boilers, water heaters and heating products up to 70kW have to include an ErP label clearly showing the specified efficiency information. This applies to the UK and the European Union so consumers are aware of the efficiency levels of the products and appliances they use everyday. This means that manufacturers now design and build all new boilers to align with the ErP requirements and any new boiler you buy will display an ErP label.


What is a flue?

A flue is a pipe that forms part of your boiler and pops out of your house through an external wall or the roof. It connects your boiler to the outside world, getting rid of all gases and condensate from inside your boiler and safely moving them them away from you, out in to the fresh air.


What is a fully pumped system?

A fully pumped system is a requirement of all new high efficiency boilers. This means that if your current central heating system is gravity fed (see ‘what is a gravity fed system?’), we have to update it to a ‘Fully Pumped’ system. This is done automatically as part of your new boiler install with no preparation work for you beforehand. The big benefit is that your new boiler and central heating system will run much more efficiently, reducing your energy consumption and saving you money.


What is a fused spur?

Regulations state that a new boiler must connect to electricity via a fused spur so that the engineer is in no danger of being electrocuted. A fused spur is an electrical point that has its own removable fuse that the engineer can remove, as well as an isolation switch that the engineer is able to turn off. If your old boiler doesn’t have a fused spur, a fully qualified and approved electrician will need to fit one close to the new boiler position. We can organise this for you or you or you can use your own contact.


What is the Gas Safe Register?

The Gas Safe Register is the UK’s official gas registration body of gas businesses and engineers and is there to protect you and your family from unsafe gas work. By law all gas businesses must be on the Gas Safe Register. Individual gas engineers can not enter on to the register but if they work for a registered business they can be issued with a license to carry gas work on behalf of the registered business, providing they hold a valid and current qualification. Just as the DVLA issues driving licences only to those who have demonstrated competency by passing a driving test. It is crucial for your safety that anyone who installs or maintains gas appliances in your home is a qualified Gas Safe heating engineer. All Gas Angel engineers are fully compliant and licensed by Gas Safe.


What is your Gas Safe number?

Gas Angel Heating Services Ltd. has a full company Gas Safe registration under the number is 231975.


What is a gravity fed system?

The force of gravity is used to circulate water around a gravity fed central heating system. You will normally find a cold water tank high up, often in the loft and then a boiler on the bottom floor, usually the kitchen. In between these two floors is where the hot water cylinder will sit. When you call for hot water tap the boiler heats up the water and because cold water is denser than the freshly heated water, it falls down to the boiler. The hot water then moves up to the hot water cylinder from where it gets forced out to the hot water taps.


What is a hot water cylinder?

A hot water cylinder is a big tubular tank that you usually find tucked away in airing cupboards or lofts. If you have a hot water cylinder it’s job is to store your homes hot water so that it’s ready for you when you want to run a hot bath or fill the sink with hot soapy water via taps. If you’re upgrading to a combi boiler that supplies you with heating and hot water on demand, you no longer need your hot water cylinder so we remove it to give you extra space. However system boilers and regular boilers (also called traditional or heat-only boilers) only directly provide central heating so you need a hot water cylinder to deliver hot water too.


What is a boiler service?

An annual boiler service is a yearly examination of your boiler by a Gas Safe Registered engineer who will inspect, test and clean various parts of your boiler. For full details see our boiler service page.


Do you have a CRB check?

Yes we are fully CRB checked and can show the disclosure on request. Yes all rented properties must have a valid gas safety check, this is to be done annually, without excuse, otherwise not only will you be breaking the law, but you will be putting your tenants potentially at risk.
