Understanding Boilers
A combi or combination boilers are the most popular type of boilers across the Uk. A combi boiler is a single unit that heats up both central heating and hot water instantly and on-demand.
They are efficient, cost less in heating bills, and space-saving compact units. They only heat water when you need it, rather than storing hot water as they don’t use external hot water storage cylinders.
These boilers are also known as Traditional, Heat only, Regular, Standard, or Conventional boilers and are most commonly found in old-built properties or properties with low mains water pressure.
They store hot water in the storage cylinder fed by a big cold water tank usually in the loft and heat up the radiators using a feed and expansion cistern ( small tank) usually in the loft too. They don’t have a built-in expansion tank like a system or combi boiler.
They are also suitable if two or more bathrooms in your home are likely to be in use at the same time but the flow of hot water depends on a gravity-fed hot water storage cylinder resulting in low flow at hot water taps and showers as compared to a combi or system boiler.
These boilers can also work along with vented or unvented hot water storage cylinders.
Yes. Both regular and system boilers can work along with vented or unvented cylinders but in some cases may need a small change to the heating or hot water controls ( motorized valves/zone valves) which you can discuss by ringing us on 0300 303 0902
About Boiler Accessories

In most cases yes, depending on the type of radiator you’re interested in, for example sourcing a designer radiator might take a day or two. You can discuss it with us during the ordering process.
In case you are out of heating and hot water we can offer to replace the odd radiator another day after your boiler installation if it suits you.
We can easily provide you a fixed cost over the phone but if it is complexed we do offer a tech visit, To see how we do it please visit https://gasheatinginstallers.co.uk/radiators-central-heating/
Alternatively for any advice or guidance please ring us on 0300 303 0902 and we’ll happy to help.
Yes, should you require a radiator to be installed in a new location, rather than replacing it, we can arrange it for you. To discuss and arrange it please call us on 0300 303 0902 or alternatively to see how we do it please visit https://gasheatinginstallers.co.uk/radiators-central-heating/
That’s fine, if you select a smaller radiator our engineer will still be able to fit this by using adjustment fittings. This means that the engineer will have to use extra piping from the existing valve to meet the radiator and you’ll see a bend where this joins the radiator.
Don’t worry, you can discuss it with our experts during the ordering process and they can offer one with the nearest height and width to the one you currently have, to minimize disruption if there is a space problem then its better to go for a slightly smaller size than your existing radiator.
If you are looking to replace the same size radiator with the one you currently have, you can provide us with the measurements (height and width) of that radiator.
Alternatively, you can send us some pictures by email at pics@gasheatinginstallers.co.uk or send them on our What’s App number 07889293101 with your name, postcode, and phone number.
It depends on how many radiators you have or plan to have in the future. The higher heat output (measured in KW) means that the boiler will have the capacity to allow you to add more radiators and they are heated at maximum output. Our technical team will be more than happy to advise you on live chat or you can call us on 0300 303 0902.
Once a flush is complete and your new boiler/radiators are installed and refilled with fresh water, the engineer will add a system protector (inhibitor) to protect the system both against system corrosion and limescale deposition.
No, As a part of our fixed price we provide a new TRV and lockshield valve with each radiator that is supplied and fitted by us.
