Boilers are often unappreciated, but in reality they’re heating heroes…

Your boiler may just look like a box, hanging around on your wall or lurking, hidden away in a cupboard, but have you ever taken a moment to appreciate what that box does?... 

It works hard every day to bring together gas, electricity and water, heating up the water for your taps and your central heating system. It heats up, cools down, pumps and makes sure your home is warm and comfortable. And that level of dedication is not to be sniffed at.

Knowing how hard your boiler works, you really need to make sure you are looking after it. It’s really important to make sure you have an annual Boiler Service carried out. 

Not only is an annual service important from a safety perspective, it can also make all the difference in terms of reliability, efficiency and the size of your household bills. Getting your boiler serviced could also prevent unnecessary boiler repairs or replacement further down the line too.  It’s important to note that if your boiler is still under warranty or guarantee, having an annual service is actually one of the conditions you have to comply with for the guarantee to stand.

If you are a Landlord, an annual service/gas safety check is a legal requirement for all of your properties. The law also requires that all servicing and gas safety checks are made by a Gas Safe registered Engineer.


A Boiler Service isn’t just a quick check under the cover…

During your boiler service,  you can expect the Engineer to do the following: 

  • Remove the boiler casing and examine the components
  • Check the gas pressure and flow is correct
  • Use a flue gas analyser to make sure the boiler is burning the right mixture
  • of gas and air, and that the exhaust gases are correct and safe
  • Check that all the electrical connections are clean and in good condition
  • Check the fans and other key components are working efficiently
  • Check that seals are intact
  • See that the electrodes are in a good condition
  • Check the safety devices 
  • Check the condensate trap and pipe is not blocked
  • Check over all the water and gas pipework
  • Check that your Boiler is working safely and efficiently overall.



There are some basic rules about boiler positioning that should be followed too…

If your boiler has been installed in a cupboard, you'll need to adhere to the manufacturer's recommended clearances so it can work safely and be accessed easily for a Boiler Service. Air vents, grilles and flues must be kept free from blockages. If you have a very old boiler and are concerned about its positioning, we can advise.

If you have concerns about your boiler performance or gas safety, it’s best to act swiftly…

If you feel your Boiler is not running correctly do not be tempted to remove the case. Only a Gas Safe registered engineer is legally qualified to remove a Boiler casing. If you think there might be a problem with your boiler, you’ll need to call a Gas Safe registered Engineer. It’s easy to forget that gas can be extremely dangerous and leaks can lead to fires, explosions and Carbon Monoxide poisoning.

Tareq's Tips #4. Six handy hints to help keep your house warm through a big chill…


It’s looking like we’re due to see some big drops in temperature through December and there might even be a touch of the white stuff. If your house isn’t keeping you as snug as a bug in a rug, we’ve got a few ideas here for easy ways to stave off the shivers and optimise your home heating throughout the winter season.

1. Cut out drafts

There are plenty of places around the home which can really let a draft in. Adding an insulation strip around your front door for example can really cut out the cold air, as can fitting a letterbox cover and keyhole cover - all easily available from your local diy shop.

2. Get your radiators working harder

At Roost Heating, we always say that bleeding your radiators regularly is a no brainer because it will help to ensure they are working as efficiently as possible. If your radiators are old then a power flush to clear out sludge build up is also a good idea. A simple diy solution to get your radiators working even harder is to add shiny silver foil behind them so more heat is reflected out into the room. If nothing seems to kickstart them into action and they’re still failing to keep you cosy, just get in touch and we can come up with a solution.

3. Achieve the optimum home temperature 

When the temperature drops, it’s often an automatic reaction to turn up your heating thermostat. It’s the thermostat’s job to maintain a constant temperature whatever the weather so fiddling about with it won’t make you any warmer. Just set it to the desired temperature (20 degrees is the general preference) and then let it work its magic. If your thermostat’s not working properly then perhaps it’s time you opted for something a bit smarter - like a nest* thermostat? Find out more here.

4. Get your boiler checked

A cold house can often be due to a boiler that’s not behaving itself. Strange clunking noises, radiators that are gurgling and not getting hot or never enough hot water can all be signs that your heating system needs an overhaul. Best to book a boiler check which may result in a simple boiler fix - and will certainly mean you can rest assured that your boiler is safe. If you do need a brand new boiler, we can advise you on the best, most economical boiler for you and we can install it too so you’ll be toasty in no time.

5. Consider your soft furnishings

Adding blackout blinds behind your curtains, or incorporating thermal interliners within your curtains can keep drafts around windows at bay and help keep your house that bit warmer. Even with modern double glazing, windows can let heat out. Similarly wooden or tiled floors can be warmed up by adding a woolly rug - or you could consider incorporating an underfloor heating system to really heat things up.

 6. Check out your chimney

If you’ve got an open fireplace that’s purely decorative , or a chimney that you never use, it might be creating a draft or taking heat away from the room. You can buy ‘chimney balloons’ at most diy shops and quickly and easily fill the gap. Obviously not suitable if you’re planning on lighting a fire, but definitely worth investing in if you just rely on your central heating system.

When it comes to home heating, economical and efficient heating solutions and clever ways to save energy, at Roost Heating we’re full of bright ideas. For further information on new boilers, underfloor heating, smart thermostats and more - just get in touch.

Tareq's Tips #1 - Going on Holiday? Don't forget to switch off your water at the mains.


If you’re jetting off on holiday to somewhere sunny (or just popping to a campsite up the road) but you don’t want to come home to a nasty, soggy surprise - it’s advisable to turn your mains water off to the house before you head out of the door.

Burst pipes, slow leaks or flooding can be stressful and expensive, particularly if they’re left for any length of time so it makes sense to prevent them happening by switching off your mains water before you go away.

It may however be the case that for you, this is easier said than done.  Traditional brass stopcock water taps are often tucked away in the most inaccessible places. Difficult to locate and often hard to turn so sometimes it’s not possible to access them or adjust them, or it just seems to be an extra hassle that you don’t have time for as you dash out of the door. 

At Roost Heating, if your stopcock is stiff or inaccessible, we recommend fitting a modern and convenient new Stopcock which means it’ll be simple for you to switch your water on and off ongoing. Whether you’re going away but you still need the neighbours to do the watering or you suddenly have a leaky pipe or burst pipe and want to stop your water supply as quickly as possible, a Surestop Stopcock will enable you to switch off your water at the touch of a button. Find out more here: http://www.surestop.co.uk/owners/

We can install a brand new Stopcock for you and ensure you’re confident to use it too.

Just drop us a line to find out more or to book. Then you can head off on your holidays with one less thing to worry about.
